Description

Scalability and Resource Management

  • Dynamic logical partitioning adds and removes processors, real memory, and I/O from active logical partitions without rebooting the systems. Processors, memory, and I/O slots can be assigned via the Hardware Management Console.
  • Dynamic Capacity Upgrade on Demand enables you to order and install POWER4 systems with additional hardware resources (processors) than what is currently required and keep these resources in reserve until they are required as future business application workloads dictate. To enable the additional resources, the system administrator can dynamically turn on the resources using DLPAR services without having to bring down the system. This function is well suited for those who have unpredictable application workload requirements.
  • Dynamic CPU Guard automatically and dynamically removes failing processors from a system image before they cause a system failure. If spare processors are available on the systems, they can automatically replace the failing processors.
  • Memory affinity support may improve the performance of memory-access-intensive, high-performance computing jobs running on multichip module p690 and p670 systems.
  • The POWER4 processor in the p690 system supports 4 KB and 16 MB virtual page sizes.

    The large page provides performance improvements to high-performance computing applications. AIX V5.2 supports large page use for both 32- and 64-bit applications and on both 32-bit and 64-bit kernels.

  • Enhanced WLM gives system administrators more control of resources. Functions such as time-based setting make changes to configuration easier. A set of processors may be associated with a WLM class. Jobs assigned to such a WLM class run only on the processors associated with the WLM class.
  • The existing per-process file descriptor limit is increased from 32K to 64K under both 32-bit and 64-bit kernels.
  • Enhanced journaled file system (JFS2) increases file and file system sizes to 16 terabytes (TB) with the 64-bit kernel. The 32-bit kernel continues to support 1 TB. Larger file systems created under the 64-bit kernel can be mounted only with the 64-bit kernel.
  • AIX V5.2 includes support for the Universal Disk Format (UDF) V1.50 file system for the pSeries and RS/6000®-supported DVD-RAM and DVD-ROM optical drives.

    With the UDF file system you can backup and restore AIX files and backup images. You can also start the system and install from disks created using the mkcd command with DVD-RAM media. Software vendors and other users can create DVD distribution media for programs and data. AIX creates and supports file names only in 8-bit OSTA compressed UNICODE format.

Reliability, Availability, and Serviceability

  • With the improved system dump estimation mechanism, system administrators have a more accurate measure of the storage required for a complete system dump. As a result, the probability of losing a crash dump due to space overflow is reduced.
  • Core dumps are generated without stopping and restarting applications. The core dumps can be sent to IBM support for further analysis. This function, combined with the snapshot backup, yields easier problem determination.
  • Hang conditions on I/O devices can be detected and recovered without bringing systems to a slow halt. Based on a user-defined timeout threshold, lost I/O is detected and the system alerts the user. Users can also configure the system for an automatic reboot.
  • More information is displayed on the second line of the LED display panel, if one is available. The extra information corresponds to the LED code that is displayed and helps system operators monitor the boot process.
  • Automated dump analysis tool, adump, is enhanced to execute custom Perl scripts for dump analysis.
  • AIX V5.2 isolates the damage caused by uncorrectable data corruptions to a user process. This can help avoid more severe situations such as an entire partition reboot or a complete system reboot if it is not partitioned.

Enterprise Storage Management

  • An industry-standard programming interface, Common Host Bus Adapter (HBA) API, accesses management information in Fibre Channel HBAs. Storage area network (SAN) developers can use HBA to manage, monitor, and deploy a SAN.
  • Logical Volume Manager (LVM) enhancements:
    • The alignment and size restrictions of I/O to the LVM device driver are removed, helping to improve large unaligned I/O performance by not requiring that the I/O devices be divided into several smaller aligned I/O devices.
    • LVM enables a RAID to increase the size of a logical unit number (LUN) up to 1 TB. After a varyoffvg and varyonvg cycle completes, the new disk size becomes effective and LVM can use the additional disk space.
    • LVM supports splitting one or more disks from an active mirrored volume group into a new temporary volume group so that a backup of the volume group can be made. The temporary volume can be disbanded and the split disk reincorporated into the original volume group. Stale partitions are automatically synchronized. Only partitions that are written to while the temporary volume group is in place need to be marked as stale and synchronized when the disks are reincorporated.
  • A snapshot feature enables a point-in-time backup of a JFS2 file system.
  • System administrators can use SMIT to specify file system sizes in blocks of 512 bytes, 1 MB, or 1 GB during creation or modification of a file system.

Cluster Systems Management (CSM)

  • CSM for AIX can manage multiple machines from one single point of control. This solution for distributed systems management allows a system administrator to install and set up a cluster that can include pSeries servers, IBM eServer xSeries™ servers, or both. The system administrator can control the cluster by using remote parallel command execution, file synchronization, hardware control, and distributed monitoring with automated responses.
  • CSM for AIX enables xSeries servers running CSM V1.3 for Linux to join the cluster and be managed along with pSeries servers from the same single point of control.
  • Use of CSM is authorized only under the terms of either 60-day Try and Buy or a full production license (5765-F67) and LUM key. Refer to the CSM — Additional Information section for details on how to obtain a Try and Buy key or production license.

System Security

  • You can perform account authentication using Public Key Infrastructure (PKI) certificates.
  • AIX V5.2 provides integrated support of the Pluggable Authentication Mechanism (PAM). The integration of standards such as RFC 2307, Kerberos V5, and PAM with existing interfaces supports new features in existing applications without the need for recompilation.
  • A new version of the cryptographically secure random number generator supports cryptographic applications that require high-quality, secure random numbers. This version replaces the existing UNIX random number generator functions as part of the UNIX standard. AIX Internet Key Exchange (IKE) uses this random generator approach to increase its security.
  • You can automate and simplify the complex tasks of configuring the AIX client machines and the IBM Directory Server for use by AIX. The administrator can unify the information used to manage the different subsystems under a common top-level container object. Also included is the newly enhanced System V print directory enablement libraries that make use of this unification.
  • AIX Simple Network Management Protocol (SNMP) enterprise-specific instrumentation defines over 150 AIX-specific SNMP MIB objects describing AIX in a new enterprise-specific MIB. In AIX V5.2, the SNMP sub-agent supports only mandatory MIB objects. The remaining objects should be supported in future releases. In addition, a new command sends SNMP traps from the command line. The administrator can send traps from scripts or any other place that needs a custom trap sent to notify enterprise management applications of an important event.
  • IBM Directory Server V4.1 includes a powerful Lightweight Directory Access Protocol (LDAP) identity infrastructure for starting comprehensive identity management applications and advanced software architectures such as Web services.
  • AIX V5.2 delivers self-managing solutions through industry-leading implementation of enterprise identity mapping, an autonomic technology initiative.
  • AIX includes the tcbck command, which monitors host-based abnormalities and reports unexpected changes in the system. The tcbck command can now report these events to the Tivoli® Risk Manager.

Network Security

  • Hardware acceleration enables IP security to offload encryption and security management to an adapter such as IBM 10/100 Ethernet PCI Adapter II.
  • IKE supports a generic data management tunnel in Dynamic Host Configuration Protocol (DHCP) environments where IP addresses are dynamically assigned. IKE also supports Diffie Hellman group 5. Symmetric keys derived using Diffie Hellman group 5 are more secure than the currently implemented Diffie Hellman groups 1 and 2. With IP security static filter rules, users can enter a description of up to 80 characters.

Development and Performance Tools

  • AIX Developer Kit, Java™ 2 Technology Edition, V1.3.1, 32-bit Version for POWER is included with the AIX base operating system. The 64-bit version is available on the AIX V5.2 Bonus Pack.
  • Performance analysis tools include support for thread (curt), lock (splat), procfs (truss and proc commands), and JFS2 (filemon and fileplace). The GUI-based Xprofiler provides an integrated environment for analyzing application CPU usage.
  • System administrators can use systems management interfaces (Web-based System Manager and SMIT) to manage performance tuning parameters and preserve those settings whenever the system is rebooted. These interfaces support operating system, memory, network, and NFS tuning parameters.
  • Available as licensed programs, the C++, C, and FORTRAN compiler products are updated to support AIX 5.2.

Network Technology and Performance

  • The Domain Name Server improves support for dynamic updates, zone transfers, security, and IPv6.
  • SNMP V3 increases security robustness through both authentication and encryption. Users can securely configure and monitor a system remotely.
  • Mobile devices that use Mobile IPv6 enable the devices to keep the same global address on supporting networks. Applications maintain transport and higher-layer connections while changing locations.
  • With enhanced network availability, an EtherChannel Link Aggregation can be backed up by a standby Ethernet Adapter. This feature is supported on the IBM 10/100 Mbps Ethernet PCI Adapter.
  • Network technology RAS features include better management of network tunables and additional kernel debugger support.
  • Asynchronous transfer mode is enhanced to increase network interoperability.

Interoperability

  • AIX Toolbox for Linux Applications includes updated versions of many useful Open Source applications.
  • CIFS/SMB Client is a new AIX Virtual File System offered in AIX V5.2. This feature allows the mounting of filesystems shared (exported) by CIFS servers including Windows® 2000, Windows XP, Samba 2.X, and AIX Fast Connect V3.1. It also allows AIX applications to access data resident on Windows and other CIFS servers.
  • AIX Fast Connect is enhanced with the support of CIFS DFS™ (MS Dfs) and LDAP-based authentication for CIFS clients. AIX Fast Connect is a licensed program providing file and print services for Windows clients on AIX 5L.

Standards

  • AIX V5.2 32-bit operating system maintains UNIX 98 branding.
  • AIX V5.2 64-bit operating system is in the process of obtaining UNIX 98 branding.
  • AIX V5.2 is designed to conform to the ISO/IEC 9899:1999 international standard for the C programming language, commonly referred to as C99.
  • AIX V5.2 is designed to provide the asynchronous input and output option from IEEE Standard 1003.1-2001.

Base Operating System

  • System libraries and headers incorporate APIs from the ISO/IEC 9899:1999 C language standard and the single UNIX specification V3.
  • A device automatic mount facility provides a mechanism to automatically mount CD and DVD filesystems. The facility is included in the bos.cdmount fileset.
  • The version of the Perl language installed with AIX is updated to 5.8.
  • System V proc commands display information in the /proc filesystem in the System V format.

System Management

  • With alternative disk installation migration, system administrators can migrate systems to a new AIX level while the systems are still operating properly.
  • Additional locales in Arabic, Chinese, English, Indonesian, Malaysian, and Spanish are introduced in AIX V5.2.
  • The use of the euro currency symbol, and the currency formatting rules concerning it, is the default currency handling method in AIX locales for those countries that are European Monetary Union members.
  • A new X output method is added for unicode locales taking advantage of an X11R6 font feature that allows an application to load the subset of a font.
  • System administrators can maintain a proactive maintenance strategy using the comparison report feature. Users can compare the filesets installed on their systems with the contents of an image repository or a list of available updates that can be downloaded from the pSeries Support Web site. This function can be executed from the command line (compare_report) or System Management Interface Tool (SMIT) (smitty compare_report). Selective reports can be used as input to request updates from the Web site.

Accessibility by People with Disabilities

Using AIX Documentation: The AIX product documentation library is available online at:

It is accessible with text-only browsers, such as Lynx, or talking browsers, such as IBM Home Page Reader. The AIX man pages are available from the command line and are accessible though the same assistive technologies used to access commands and output.

Using the Command Line: AIX makes all of its functions available for use through the command line so that they can be supported by assistive technologies that support the Emacs environment. The command interface is also accessible remotely using assistive technologies, such as JAWS, which support Telnet or terminal emulator environments in the Windows operating system.

Using Web-Based System Manager and SMIT: Web-based System Manager offers full keyboard accessibility and limited support for changing font size for system administrators. Screen reader support is not currently available. SMIT menus are accessible through the same assistive technologies that provide command-line accessibility. The character-based version of SMIT (which is activated with the smitty command on a graphical terminal) should be used instead of the Motif, or GUI, version activated with the smit command.

Using X Keyboard Extensions to Increase Accessibility in the X Windows System Environment: If you are using Telnet or a terminal emulator program to access AIX, keyboard-accessibility features are provided by either the application or your operating environment. For example, in the Windows operating system you can open the Control Panel and select Accessibility Options to enable and adjust keyboard accessibility settings. Keyboard-accessibility options are also available on an AIX graphical console running the X Window System software or the Common Desktop Environment (CDE). Refer to the Accessibility link on the pSeries Information Center, or your AIX or CDE documentation, for more information on configuring and using accessibility features of the X Window and CDE environments.

AIX Installation: Installation menus and other screens displayed during base AIX installation are not accessible. Use Network Installation Manager (NIM) as an alternative means of installing AIX. IBM assumes that Section 508 applies only to normal and routine end-user operations, and not to setup and service functions.

XPROFILER: The performance tool, xprofiler, is a Motif program that does not meet all accessibility requirements. Use the text-based tool, gprof, to provide the same information in tabular form.

Statement of Direction

Common Criteria Security Certification: IBM is in the process of applying for Common Criteria Security Certification for AIX 5L for POWER V5.2. This security certification will be performed by an independent auditing organization and will be assessed based on Controlled Access Protection Profile (CAPP) and Evaluation Assurance Level (EAL-4+) requirements.

Completion of the initial certification is planned for the first half 2003.

For a list of products and systems that IBM has agreed to publish before completion of the certification procedure, visit:

As government and military use of IT grows so will the number of threats directed against their critical IT infrastructures. As an industry leader in security solutions, IBM is helping U.S. Government and military agencies assess their security needs, protect data and assets, detect threats and intrusions, and recover from incidents. In January 2000, the U.S. Government issued a new policy known as NSTISSP No. 11 (National Security Telecommunications and Information Security Systems Policy 11). The goal of NSTISSP No. 11 is to ensure that commercial software products acquired by the U.S. Government for use in national security systems perform as advertised and satisfy the security requirements of the government users. As of July 1, 2002, NSTISSP No. 11 requires all commercially acquired security-enabled products that will be used in national security systems to be independently certified by approved testing facilities against the International Common Criteria for Information Technology Security Evaluation (Common Criteria or CC).

CC is a catalog of elementary security and assurance requirements. These requirements can be selected, extracted, and possibly further refined and packaged into two standardized constructs: protection profiles (PP) and security targets (ST). Assurance requirements to be incorporated into these constructs are defined and cataloged in the CC as a set of seven increasing levels of assurance, from the lowest evaluation assurance level (EAL1) to the highest (EAL7). Thus, the CC provides a comprehensive, rigorous language and flexible method for specifying security requirements.

A PP is a detailed statement of security and assurance requirements that users want in a class of IT products such as an operating system. On the other hand, the ST is a detailed statement of what a specific vendor product (for example, AIX 5L) offers in terms of the specific security and assurance requirements.

Multi-Path I/O: IBM provides Multi-path I/O (MPIO) enabling technology in AIX that supports multiple host connections to external storage devices. This technology will facilitate higher system-wide availability, performance, and flexibility in many storage network environments. This function is introduced starting with AIX 5L V5.2.

AIX MPIO is designed to work in conjunction with software delivered by IBM and third-party storage providers to allow shared, concurrent paths to storage in a Fibre Channel storage-networking environment.

IBM will offer an MPIO application development toolkit to storage providers that have an agreement with pSeries/AIX for qualification or service.

A white paper describing MPIO in greater detail is available at:

SP™ System and Parallel System Support Programs (PSSP): AIX V5.2 is not supported on the RS/6000 SP system at this time, nor on any PSSP-based cluster of servers. IBM intends to provide support for AIX V5.2 with the PSSP for AIX product on Cluster 1600 systems in 2003.

AIX Developer Kit, Java 2 Technology Edition: IBM plans to release the 32-bit SDK for AIX, Java 2 Technology Edition, V1.4 and 64-bit SDK for AIX, Java 2 Technology Edition, V1.4 in fourth quarter 2002. Both of these products will be supported on AIX V5.2. Beta versions are now available at:

In first quarter 2003, IBM plans to support the AIX Developer Kit, Java 2 Technology Edition, V1.2.2 on AIX V5.2.

These statements represent the current intentions of IBM. IBM development plans are subject to change or withdrawal without further notice. Any reliance on this Statement of General Direction is at the relying party's sole risk and will not create any liability or obligation for IBM.

All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice.

Additional Information

Scalability and Resource Management

Dynamic Logical Partitioning (LPAR): Dynamic LPAR increases the flexibility of partitioned systems by enabling system administrators to:

  • Add and remove processors, real memory, and I/O slots from active LPAR partitions
  • Assign hardware resources where they are most needed
  • Adjust to changing hardware requirements within an LPAR environment without impacting system availability

The addition and removal of hardware resources are supported at the level of a single processor, a 256 MB real memory block, and a single I/O slot. Under Dynamic LPAR, system administrators use a GUI to add and remove hardware resources through the Hardware Management Console.

Memory Affinity: The performance of memory-access, intensive high-performance computing (HPC) jobs running on multiple multi-chip module (MCM) pSeries™ 690 and 670 systems is improved.

  • A vmtune memory affinity option requests that the AIX® virtual memory manager (VMM) allocate physical memory close to the processor requesting the physical memory.
  • The AIX Workload Manager (WLM) allows system administrators to associate a set of processors with a WLM class.
  • Jobs classified with such a WLM class run only on the processors associated with that class.
  • WLM support allows installations to bind their HPC work to one or more processors; the virtual memory affinity support ensures the physical memory is allocated close to those processors.
  • Installations must explicitly enable the virtual memory affinity and WLM support, but enabling memory affinity can cause performance degradation in some workloads.

New commands and programming APIs bind processes to a collection of processors. This can be used instead of, or in addition to, WLM for binding HPC work to processors. A new environment variable processes requests for preferential local MCM memory allocation when memory affinity is globally enabled. AIX uses a "round robin" memory allocation scheme where memory allocations are distributed across all MCM memory.

Large Page Support: The POWER4™ processor in the pSeries 690 system supports two virtual page sizes:

  • Standard POWER architecture 4 KB
  • New 16 MB page size

The use of large pages improves the performance of high-performance computing applications. Memory-access-intensive applications that use large amounts of virtual memory may improve performance by using large pages. These large-page performance improvements are attributable to reduced translation lookaside buffer misses due to this buffer's ability to map a larger virtual memory range. Large pages also improve memory prefetching by eliminating the need to restart prefetch operations on 4 KB boundaries.

The POWER4 large page architecture requires that all virtual pages in a 256 MB segment be the same size. AIX uses this architecture to support a mixed mode process model. Some segments in a process are backed with 4 KB pages and other segments are backed with 16 MB pages. Applications can request that their heap or shared memory segments be backed with large pages. Other segments in a process are backed with 4 KB pages.

AIX supports large page use for both 32- and 64-bit applications.

WLM: New functions for system administrators include:

  • You can define a configuration set that contains a list of configurations and a time range for which each is active simplifies the configuration of different resource allocation policies based on time of day and day of the week. You can use WLM configuration menus in SMIT and Web-based System Manager to automate changes in the configuration.
  • You can define per-process limits on the total consumption of CPU time, blocks of disk I/O, and connect time of a login session. You can define these limits for each class and apply them to every process in each class. After a process reaches one of these limits, it is warned and killed, ensuring protection against malfunctioning or malicious programs trying to overuse system resources.
  • You can define per-class absolute limits on the number of processes, threads, and logins in each class. When one of these limits is reached, WLM prevents the creation of new processes, threads, or login sessions.
  • From the Web-based System Manager interface, you can register for notification of WLM-related events and define an action to be taken in response to the events.

Reliability, Availability, and Serviceability

Corrupt Page Process Termination: POWER 4 systems can handle many uncorrectable data errors so that system operation continues until the data is actually used by a processor. With AIX V5.2, if the data associated with an uncorrectable error is used only by a user process as opposed to the kernel or system firmware, the process using the data is terminated.

Diagnostic Use of Physical Location Codes: Physical location codes map logical functions in a platform (or expansion sites for logical functions, such as connectors or ports) to their specific locations within the physical structure of the platform. In AIX 5.2, the diagnostic subsystem expands the use of physical location codes to include devices other than those represented in the RISC System 6000 Platform Architecture (RPA) Open Firmware Device tree. Devices such as plug-in PCI adapters and storage devices are represented by their physical location code.

Enhanced Scan Ring Dump Interface: With this interface you or service personnel can choose to either fast boot the system or gather extensive error information during a checkstop, and change your choice without rebooting the system.

Trace GUI: A sample Trace GUI is included. After the installation, the file /usr/samples/trcgui/README is available for more information about how to start this Java™ application. This application helps analyzing AIX trace through a GUI.

Enterprise Storage Management

Common Host Bus Adapter (HBA) API: The Common HBA API specification Rev 1.92, developed through the Storage Networking Industry Association, provides a standard and consistent interface for accessing information in the Fibre Channel Storage Area Network. The Common HBA API includes a set of C programming language library functions, enabling access to Fibre Channel HBA attributes and operating system mapping information.

Logical Volume Manager (LVM) Enhancements

  • AIX V5.2 removes the I/O size and alignment limitations from the LVM device driver resulting in fewer "iodone" calls to the kernel when LVM is finished processing an I/O. The reduction of these calls helps improve overall system performance as well as file system performance by reducing the amount of processing each I/O takes. Enhanced journaled file system (JFS2) takes advantage of the removal of the alignment limitation in LVM for both data and meta data. JFS2 Direct I/O issues a single large I/O to LVM for the contiguous space within the underlying logical volume. Asynchronous I/O issues one larger I/O to the LVM layer rather than splitting that large I/O it up into several I/Os.
  • LVM supports splitting one or more disks from an active volume group into a new temporary volume group so that a backup of the volume group can be backed up. The temporary volume group can automatically be disbanded and the split disk or disks automatically reincorporated into the original volume group.

File System Enhancements

  • A simple backup of an online file system can produce inconsistent data because individual files are read at different times. A snapshot backup gets an image of the file system with all files in the state that they were in at the time of the snapshot. Because many applications require consistency across files, the application data is backed up in a consistent, reliable state.
  • System administrators can now use SMIT to specify file system sizes in blocks of 512 bytes, 1 MB, or 1 GB when creating or modifying a filesystem. Furthermore, cfrs and mkds commands can be invoked by SMIT. The commands du and dk display information about filesystems in a readable format.

CSM — Additional Information

CSM for AIX manages multiple machines from a single point of control, a pSeries server running AIX V5.2, known as a management server. The machines within the cluster, called managed nodes, can be pSeries servers running AIX 5L for POWER V5.2 or AIX 5L for POWER V5.1 with the 5100-03 recommended maintenance package. They can also be xSeries™ servers running CSM V1.3 for Linux Red Hat 7.2 or 7.3.

CSM for AIX includes the following systems management functions:

  • Installation and setup commands create and configure the cluster and set up security for the administrator.
  • Node groups are formed across nodes in the cluster either statically or dynamically. For example, a dynamic node group can be created for AIX machines and a dynamic node group created for Linux machines, and as a node is added to the cluster, it automatically becomes part of one of these node groups.
  • Commands are run across multiple nodes in the cluster and responses gathered. Commands can also be run across specific node groups.
  • A configuration file manager synchronizes files across nodes or node groups in the cluster.
  • Various conditions can be monitored across nodes or node groups in the cluster and actions can be run in response to specific events:
    • Monitoring includes whether the node is up or down; whether applications or daemons running on the node are up or down; and CPU, memory, and file system use.
    • Actions that can occur in response to an event, such as a filesystem filling up or a node going down, include running commands on the management server or on any node of the cluster, or either logging the event or e-mailing or paging the system administrator. SNMP traps can also be generated.
  • Nodes are powered on and off in the cluster, providing the node has a means for remote hardware control.
  • Diagnostic tools detect the health of system status.

All functions can be performed from a command line, SMIT, or Web-based System Manager.

A CSM GUI is provided by new applications and plug-ins integrated into the Web-based System Manager Console. You can:

  • Update and remove nodes from a CSM cluster.
  • Create, delete, and modify static and dynamic node groups in a CSM cluster.
  • Perform™ single-system management functions on a node in a CSM cluster (AIX nodes only).
  • Perform hardware control operations on nodes in a CSM cluster that have hardware control support. With the hardware control operations, you can power on, power off, or reset nodes in a CSM cluster.
  • Support a CSM cluster that contains both AIX and Linux nodes (the CSM management server must be an AIX system).
  • Support distributed monitoring of conditions across a set of nodes in a CSM cluster, including visual monitoring support for the Nodes and Groups applications.
  • Run a distributed command across a set of nodes or groups or the entire cluster. The results of the command, organized by target host, can be viewed in real time. In addition, a Perl script can be generated for the distributed command to allow for script automation. This same function is available in a stand-alone GUI application, which can be started from the AIX command line or Linux command line.

Use of CSM is authorized only by a license key. For production key order information, refer to Software Announcement 202-262 , dated October 8, 2002.

You can experience the power and value of CSM and clustering at no charge for 60 days under the Try and Buy option. Simply run /opt/csm/bin/csmconfig -L and accept the 60-day IBM License Agreement (ILA). You can then use all functions of CSM for 60 days, after which CSM will no longer function. After you purchase and receive a full production license and key for 5765-F67 and accept its IPLA License Agreement, you can use CSM for production purposes. CSM configuration data stored during Try and Buy will remain available for later production use.

System Security

Public Key Infrastructure (PKI): AIX V5.2 increases security by performing account authentication using PKI certificates. When you choose PKI as the authentication mechanism, you are issued PKI x509 certificates. An existing AIX user can request certificates from the certificate authority included in AIX V5.2 base media and use this certificate for account authentication. When a user authenticates to AIX using a PKI certificate, the user's authentication certificate is associated with the running process as a proof of user identity. Certificate-based login is performed through AIX loadable authentication modules mechanism and transparent to the end user. A set of command line tools is provided to manage certificates. The PKI functions of AIX are launched only in the integrated presence of the IBM LDAP directory.

Pluggable Authentication Modules (PAM): AIX V5.2 provides integrated support of PAM, a system that defines a set of functions for authentication, account management, password management, and session management services through a configurable set of loadable modules. This is accomplished on AIX through a loadable authentication module and a PAM module, providing two independent paths of PAM integration. Access is provided from the AIX security interface to PAM services by means of a loadable authentication module. Conversely, access is provided from the PAM interface to AIX security services through a PAM module. This results in a degree of integration that allows commonplace components of the AIX system, such as login, su, and ftp to access PAM services and for PAM-enabled applications to access AIX security services.

System administrators can perform the following tasks:

  • Choose any authentication service available on a system to perform end-user authentication for an application.
  • Use multiple authentication services as a means of integrating authentication technologies with system-entry services.
  • Add new authentication service modules to a system and make them available without having to modify any applications.

AIX Implementation of RFC 2307: LDAP user authentication is updated to support RFC 2307 for both IBM Directory server and client configurations. A RFC 2307-enabled IBM Directory server can support any RFC 2307-compliant client system or application. AIX client systems can communicate with any LDAP servers that are RFC 2307-compliant. Through configurable-attribute mapping, AIX client systems can authenticate LDAP users for LDAP servers with any vendor schema.

AIX V5.2 supports naming service through LDAP with RFC 2307. You can configure IBM Directory servers and client systems for naming service and naming resolution through LDAP.

AIX V5.2 further increases security by allowing distributed environments, such as LDAP, to define the "hostsallowedlogin" and "hostsdeniedlogin" user account attributes that control users' access to client systems.

IBM Directory Server 4.1: New or enhanced functions include:

  • C programming language API for AIX client that expands the previous SDK and allows non-SSL 64-bit IBM Directory applications.
  • Dynamic groups that are defined using a search expression. When an attribute is added to a directory entry, the entry automatically becomes a member of the group. In addition, simple and efficient methods are provided for client applications to do the following:
    • Test whether a specific entry is a member of a specific group
    • List all the members of a specific group
    • List all the groups to which a specific entry belongs

    The search expressions can be used in combination with existing group attributes. These groups can also be used for access control.

  • Multiple clients can update their directories simultaneously.
  • Communication between the server and plug-ins and search and compare performance are significantly improved.
  • Nesting of groups enables hierarchical relationships to define inherited group membership. A nested group is a child group entry whose domain name is referenced by an attribute contained within a parent group entry. A new attribute explicitly distinguishes nested groups from ordinary members.
  • The IBM Directory C client and server now use the Network Authentication 1.2 C client on AIX operating systems.
  • With paged results control, you can manage the amount of data returned from a search request. You can request a subset of entries (a page) instead of all results at once. Subsequent search requests display the next page of results until the operation is canceled or the last result is returned.
  • Process size limit for the slapd daemon is increased from 256 MB to 2 GB, enabling increased cache sizes and better scalability. In addition, database connections on AIX now use local loopback TCP/IP connections, which eliminate the need for shared memory segments and make 2 GB of memory available for a server running on an AIX operating system. This also greatly increases the number of available database connections.
  • The sorted search control enables a client to receive search results sorted based on a list of criteria, where each criterion represents a sort key. This moves the responsibility of sorting from the client application to the server.

Enterprise Identity Mapping (EIM): EIM, an autonomic technology initiative, helps create a self-managing computing environment. EIM maps a user identity on one system to one on another system. Applications that use the EIM C/C++ programming interface can equate "jsmith" in the pSeries environment to "janesmith" in the zSeries™ environment. EIM is an LDAP-based application that uses the LDAP database as a central repository of user mapping information. EIM can lead to better tools for managing user IDs belonging to an individual within an enterprise, and simplify applications that run on multiple platforms. EIM is planned to be made available on all IBM eServer™ platforms.

AIX Security Enhancement to Support Tivoli® Risk Manager: Tivoli Risk Manager is an enterprise-wide risk management solution that enables organizations to centrally manage attacks, threats, and exposures by correlating security information from firewalls, intrusion detectors, vulnerability scanning tools and other security checkpoints. With Tivoli Risk Manager, system administrators who are not security experts can monitor and assess security risks in real time with a high degree of integrity and confidence across an organization's multiple security checkpoints.

Network Security

IP Security (IPSec)

  • IPSec is the building block for virtual private network (VPN) support. VPNs support secure, private connections among corporate users (intranet), business partners (extranet), off-site employees, telecommuters (remote access), and customers (e-commerce), all using the Internet as the transport facility. Cryptographic algorithms offloaded to the hardware include data encryption standard (DES), Triple DES, and authentication algorithms, including Keyed-Hashing for Message Authentication, Message Digest Algorithm, and HMAC Secure Hash Algorithm. IPSec packet encryption and authentication are achieved using Authentication Header, Encapsulated Security Payload, or a combination of the two. IPSec performance is improved with higher network traffic throughput and less CPU use.
  • With IPSec static filter rules, you can enter a description of up to 80 characters. This feature enables customization of the rules and makes them easily identifiable.

Internet Key Exchange (IKE)

  • AIX V5.2 IKE supports a generic data management tunnel, allowing any address to match the generic tunnel definition. It can be used as long as the rigorous security validation was successful in the key management negotiation phase. This feature is beneficial in DHCP environments where the IP addresses are dynamically assigned. This capability can be easily managed through the XML interface (ikedb command) or SMIT.
  • IKE supports Diffie Hellman Group 5 (DH Group 5). Diffie Hellman Key exchange is a public key crypto system where public values are exchanged to arrive at a symmetric key. Each DH group defines a prime and a generator function to use when deriving a symmetric key. Symmetric keys derived using DH Group 5 are more secure than the currently implemented DH groups (Groups 1 and 2). The Web-based System Manager includes DH Group 5 support. Also, the Web-based System Manager for IKE promptly handles management of more tunnels.
  • The SMIT user interface includes IKE tunnel support and basic IKE database functions. The SMIT interface uses underlying XML command functions to perform additions, deletions, and modifications to the IKE tunnel definitions. IKE SMIT is useful in configuring the IKE tunnel quickly and gives examples of the XML syntax used to create IKE tunnel definitions. The functions of backing up, restoring, and initializing the IKE database are also new to SMIT.

Development and Performance Tools

AIX Developer Kit, Java 2 Technology Edition, V1.3.1: You can dynamically reconfigure an LPAR running a Java 1.3.1 application.

Note: Decreasing the number of CPUs or real memory allocated to a LPAR will likely degrade the performance of the application, but the application should continue to run.

You can also dynamically reconfigure an LPAR running an older version of Java with one exception: if the LPAR has only one CPU, then AIX will reject any reconfiguration request that tries to increase the number of CPUs allocated to the LPAR.

The service end date for this version of Java is April 30, 2004.

Performance Analysis Tools: Performance analysis tools include these new utilities:

  • Xprofiler : A new GUI-based gmon data analyzer is included in the AIX V5.2 base operating system.
  • Curt : A new tool to provide high-level CPU use reports for kernel thread activities for different levels such as system as a whole, processor, process, and kernel threads.
  • Splat : A new lock analysis tool to support kernel simple and complex locks, pthread mutex, rwlocks, and condition variables.
  • Tprof : System and application profiling tool supports new output reports, reduced trace recording sizes, and latest Java JVMPI. Additionally, the tool requires significantly less time to process collected data. Annotation of listing files is now provided in addition to existing source file annotation.
  • Truss : Updated with various new options including support for library calls tracing.
  • Filemon and fileplace : Supports trace and file placement reports on JFS2 file systems.
  • System Performance Tuning : Allows administrators to use the system management interfaces (Web-based System Manager and SMIT) to adjust, make permanent, and save operating system, virtual memory, network, and NFS tuning configurations. This new function centralizes the use of the tuning parameters controlled previously by schedtune and vmtune, as well as the parameters handled by no and nfso commands. Configurations are stored in files that can be copied onto multiple machines. Logging is also provided during reboot. The sample programs vmtune and schedtune will not be supported in the future releases following AIX V5.2. In AIX V5.2, they are replaced by compatibility scripts calling the new fully supported commands vmo, ioo, and schedo. The syntax of no and nfso is expanded to support permanent changes and online help. All five system tuning commands (no, nfso, vmo, ioo, and schedo) now use the same expanded syntax.
  • The perfstat library is enhanced with new interfaces to collect disk adapters, paging spaces, network buffers, and network protocols performances metrics.

Kernel Debugger (KDB) Enhancements

  • Both command and kernel kdb support a new "print" command so that users can display memory areas as C data structures.
  • The kdb command supports pipe facility for its input. This option enables users to pipe the output to filter the information. The session activity can be captured in command kdb using the set-log file option.
  • The kdb command and KDB provide the same level of command-line editing as in the crash command. The kdb command support vi, emacs, and gmacs edit modes.
  • Both kdb command and KDB display network device driver details as well as network statistics.

Network Technology and Performance

BIND V9 Domain Name System (DNS)

  • DNS acts as both an authoritative server for DNSSEC secured zones and as a caching server for DNSSEC secure resolution on behalf of clients.
  • Incremental zone transfer protocol, as specified in the RFC 1995, allows secondary DNS servers to transfer and incorporate any cumulative changes made to the primary zone since the last transfer. It notifies the process as specified in RFC 1996, which allows the primary DNS to notify the secondary DNS when zone data is updated.
  • DNS communicates using IPv6 transport and supports AAAA records.

Simple Network Management Protocol (SNMP) V3: AIX V5.2 includes both the encrypted and non-encrypted versions of SNMP V3. The encrypted version, with 56-bit DES, is included in the AIX V5.2 Expansion Pack media. The non-encrypted version is included on AIX base operating system media. SNMP V3 features:

  • A utility to generate keys based on password and IP address
  • A utility to change keys dynamically
  • An SNMP V3 manager application
  • An SNMP V3 agent, owning all requests and behaving as a DPI2 server agent and a SMUX server agent

The most important feature is security with the User-Based Security Model instead of community name.

Mobile IPv6: AIX V5.2 supports mobile devices using Mobile IPv6. Mobile devices keep the same global address on networks that support Mobile IPv6, which allows applications to maintain transport and higher-layer connections while changing locations. With Mobile IPv6 support, AIX hosts can act as the following:

  • Home agent node for mobile devices, which helps other devices communicate with the mobile devices while away from their home network
  • Stationary correspondent node that can communicate with mobile devices
  • Router node in a network visited by the mobile devices that can send router advertisements to aid movement detection by mobile nodes

FTP Server: The FTP server (ftpd) is enhanced to:

  • Restrict access for specific users or users belonging to specific groups to only their home directories.
  • Control access so that only users from specified hosts are allowed or denied access when using FTP.
  • Specify certain directories to be either read-only or write-only when accessed using ftp.
  • Support multiple line login heralds, both before and after login.

Network RAS

  • A standby Ethernet adapter can backup an Etherchannel Link Aggregation, improving network availability. This feature is currently restricted to the IBM 10/100 Mbps Ethernet PCI (23100020) Adapters.
  • SMIT support makes management of network tunables easier to retain across system reboot.
  • The network kernel debugging support is improved with the addition of support for the netstat and ndb commands.

Asynchronous Transfer Mode (ATM) Enhancements: AIX V5.2 includes the following enhancements to increase network interoperability:

  • User to Network Interface V4.0 and Integrated Local Management Interface V4.0 are supported.
  • Party function allows sharing of point-to-multipoint virtual circuits.
  • The incoming add party requests allow multiple LAN Emulation (LANE) clients to operate on the same emulated LAN over a single port.
  • Hardware-assisted IPv4 TCP checksum offload support for classical IP, LANE, and MPOA.
  • LANE clients can select maximum frame size values other than the standard legacy frame sizes. Any LANE forum value of 1516, 4544, 9234, or 18190 can be specified for Ethernet or token-ring LANE.
  • Dynamic maximum transmission unit (MTU) in LANE and TCP/IP is supported to handle changes to the MTU size after recovering from a network outage.

Interoperability

The toolbox is a collection of software commonly found with Linux distributions. Over 360 different images are available for installation.

The AIX Toolbox for Linux Applications is packaged on separate media and distributed at no charge, or visit:

The Web site is updated on an ongoing basis. The AIX Toolbox for Linux Applications is not supported by IBM and is provided as is, under the terms and conditions of the license on the AIX Toolbox CD or Web site.

AIX Fast Connect V3.1.2: AIX Fast Connect offers file and print services for Windows® clients on AIX 5L. It includes the following enhancements:

  • Implementation of Microsoft™ Distributed File System provides a logical namespace for access to files distributed across a network.
    • Multiple machines can be mapped to a single logical name.
    • Single drive mapping can accommodate the entire namespace.
    • The physical topology is simplified and hidden.
  • Implementation of level II Oplocks helps improve the performance of the server.
  • LDAP exploitation authenticates users with LDAP-based user objects. It supports existing user databases in the directories that use LDAP access, such as Active Directory and NDS. Fast Connect configuration information also can be stored as LDAP directory objects.
  • Additional print support in Fast Connect displays the complete file name instead of truncated file name or job ID in the PC clients printer status window.
  • Windows XP clients are supported, in addition to existing support for Windows 9x, Windows NT®, and Windows 2000 clients.
  • With Web-based system manager and SMIT enhancements, you can configure the new features implemented in Fast Connect.

Base Operating System

Base Commands and Libraries

  • The system libraries and headers incorporate APIs from the ISO/IEC 9899:1999 C language standard (C99) and the single UNIX® specification, V3, including:
    • Complex arithmetic support
    • Standardized floating point environment interfaces
    • Type-generic math

    New headers include:

    • fenv.h
    • tgmath.h
    • complex.h

    The math library has 164 new interfaces available. The new interfaces are exposed to applications unless the applications specifically target earlier levels of the standards by setting variables from standards.h.

  • A utmpd daemon cleans up stale records in the system login file.
  • The malloc debug facility is enhanced for improved serviceability.
  • The "last" command will now display the full hostname.
  • System administrators can now use chlicense at the command line to immediately change the number of available fixed user licenses without rebooting. The lslicense command shows the number of fixed licenses available for use at any time.

System V proc Commands: System V proc commands display information in the /proc filesystem in the System V format. These commands are:

  • procflags
  • proccred
  • procsig
  • procstop
  • procwait
  • procrun
  • procmap
  • procldd
  • proctree
  • procstack
  • procwdx
  • procfiles

Directory-Enabled Printing: Directory-enabled printing is an add-on feature to the System V Print subsystem. Its availability enables users who are more comfortable with System V printing to more easily use AIX V5.2. System administrators can create print queues on an LDAP server, which can be accessed by users on the LDAP network. One queue can be defined for an entire network, and all users on the same network can send jobs to that print queue without additional administrative work.

Systems Management

Alternate Disk Installation Migration: System administrators can migrate their systems to a new AIX level on the side while the systems are still operating properly. Users can create a copy of rootvg to a free disk (or disks) and simultaneously migrate it via NIM to a new release level. Advantages of using alternate disk migration over a conventional migration are:

  • Reduced down time
  • Quick recovery when the migration fails
  • High degree of flexibility and customization

For details on alternate disk migration, NIM, migration, and other installation issues, refer to the latest editions of the following publications:

  • AIX V5.2 Installation Guide and Reference
  • AIX Installation Guide

New Locales: AIX V5.2 expands the number of locales supported by 21. The newly supported locales are:

Unicode Enhancements: A new X Output Method (XOM) for unicode locales takes advantage of an X11R6 font feature that allows an application to load just a subset of a font. This subsetting breaks the monolithic UCS-2 font into many smaller pieces. The new XOM then uses on-demand loading to load only those pieces of the font that are actually used. This drastically reduces the number of characters in the UCS-2 font that actually get loaded, and increases the speed of starting an application (X-Windows or Motif) in the unicode locales.

Documentation Technology

pSeries Information Center: The pSeries Information Center is more than a portal to documentation. From this Web site, you can access the following tools and resources:

  • A message database that shows what error messages mean and, in many cases, how you can recover. This database also provides information for LED codes and error identifiers.
  • Several how-to tips with step-by-step instructions for completing system administrator and user tasks.
  • Several FAQs for quick answers to common questions.
  • The entire AIX software documentation library for V4.3, V5.1, and V5.2. Each book for V5.1 and V5.2 is available in PDF format, and abstracts for books for V5.2 are provided.

Included in the AIX software documentation library are books that centralize information previously located throughout the library and easier access to some new AIX functions:

  • AIX V5.2 Security Guide gives system administrators complete information on file, system, and network security. This guide contains information about how to perform such tasks as hardening a system, changing permissions, setting up authentication methods, and configuring security features.
  • A new book covering how to plan for partitioned-system operations can help you understand these functions and how to plan for and apply them to your systems.
  • Links to the entire pSeries and RS/6000® hardware documentation library.
  • A resources page that links users to other IBM and non-IBM Web sites proven useful to system administrators, application developers, and users.
  • Links to related documentation from IBM, including white papers, Redbooks™, and technical reports on topics such as RS/6000, SP™, and HACMP for AIX. A link to the documentation search tool is provided for each release, along with links to the release notes and readme files.

New System Support

  • pSeries 630 Model 6C4
  • pSeries 630 Model 6E4

New I/O Support

  • AIX support for 16/48X IDE DVD-ROM drive on pSeries systems.
  • AIX support for 16/48X SCSI Auto-Docking DVD-ROM drive on pSeries 670/690 systems.
  • AIX boot support for IBM FAStT200 Storage Server, IBM FAStT500 Storage Server, and IBM FAStT700 Storage Server.
  • Enhanced I/O error handling increases system availability with a recovery strategy for errors that occur during I/O operations on the PCI bus. AIX support of this feature uses specific pSeries hardware enablement, which allows each PCI slot to function as a separate PCI bus. When a PCI bus error occurs, each adapter is isolated; error recovery is achieved without affecting the operation of other adapters in that system.

Support Removals for Microchannel Architecture (MCA) and PR*P Architecture

AIX V5.2 and future releases do not support:

  • RS/6000 or OEM hardware based on the MCA bus
  • SP nodes based on the MCA bus
  • RS/6000, Power Personal Systems, or OEM hardware based on the PReP architecture
  • POWER1, POWER2™, POWER Single Chip (RSC), POWER2 Single Chip (P2SC), and 601 and 603 processors
  • PCI adapters that were only available on PReP hardware
  • All ISA adapters

Enhanced AIX Operating System Subscription

Enhanced AIX Operating System Subscription is an optional one-year or three-year contract offering that enables you to maintain software product version and release currency for AIX at a predetermined cost. Under the Enhanced AIX Operating System Subscription, you can receive all software product versions, release upgrades, or product refreshes announced during the contract period. If you allow either the one- or three-year software subscription offering to expire without renewal, you can use the after-license option to renew the offering.

Definition of Software Upgrade: An upgrade is either a new version (4.x.x to 5.x.x) or a new release (5.1.x to 5.2.x) of an AIX operating system announced as eligible under the Enhanced AIX Operating System Subscription offering.

The subscription entitles you to upgrades from withdrawn AIX operating system versions and releases to currently available and future AIX operating system version and releases. Refer to the Ordering Information section for details on how to order.

Note: Software preventative maintenance releases x.x.1 to x.x.2 (modification level changes, updates, or refreshes) are available under the one-year or three-year subscription program numbers when supply features have been announced or when content of an existing supply feature has been changed. Preventative maintenance releases can be obtained by subscription customers in the same manner as non-software subscription customers. Refer to the Ordering Information section for details on how to order based on your situation.

IBM may announce a product that can be substituted for an enrolled product. This product is neither a new version, new release, nor a preventative maintenance release of that enrolled product. IBM may provide those customers enrolled in the Enhanced AIX Operating System Subscription offering access to this product at a discounted rate. The terms of this transaction will be included in the new product announcement.

Note: IBM will not offer stand-alone upgrades as a standard product offering.

Contract Duration: The Enhanced AIX Operating System Subscription contracts are offered for one or three years. The one-year or three-year prepay option can be purchased at the same time a license for an eligible AIX operating system is acquired. Refunds do not apply if cancellation occurs during one- or three-year contract period. Customers are not required to renew under either the one- or three-year offering when the contract expires but will need to use the after-license option should they let the contract expire and want to acquire a new version or release of an eligible AIX operating system.

If the one- or three-year contracts are not renewed, the one- or three-year contracts will be removed from IBM administrative systems. Contract transfers within an enterprise are allowed.

Payment Options: Customers enroll in the plan at a reduced initial price at the same time a new license for an AIX operating system is acquired. Customers can also enroll in the plan after acquisition of a new license for an AIX operating system through the purchase of an after-license option.

Enhanced AIX Operating System Subscription Prices: The Enhanced AIX Operating System Subscription program prices are based on "processor capability" as offered when acquiring licenses for AIX 5L for POWER V5.1 or V5.2, not installs, as offered when acquiring licenses for AIX V4.3.

Minimum Contract Value: None

Notification of Upgrade Availability and Ordering: Changes are currently underway to the Web server where customers can register for e-mail notifications when Enhanced AIX Operating System Subscription products are upgraded. The Software Maintenance component of the Web server is available at:

Upgrade Deliverables: Entitlement includes:

  • Media supply
  • Softcopy publications
  • Hardcopy entitled publications

Adding New Licenses to an Existing Contract: New software licenses cannot be added to an existing Enhanced AIX Operating System Subscription. No proration is allowed. As new AIX operating system licenses are added, a new contract should be ordered for those licenses.

Adding Previously Installed Licenses to an Existing Contract: You cannot add installed product licenses to a contract that were not initially covered by an existing contract. These licenses should be added using the after-license features under new and separate Enhanced AIX Operating System Subscription contract. The protection expires when the originally dated Enhanced AIX Operating System Subscription contract is not renewed.

Compatibility

Applications from Earlier AIX V5 Releases: AIX 5L V5.1 applications written for RS/6000 POWER3-, POWER4-, and PowerPC-based models can be executed on AIX 5L V5.2 without recompilation for the same and newer models in that processor family (POWER3, POWER4, or PowerPC). Exceptions are applications compiled using POWER3-, POWER4- or PowerPC-specific compiler options but executed on models other than POWER3, POWER4, or PowerPC, respectively, or applications using:

  • Nonshared compiles of AIX-shared libraries
  • Features explicitly described as nonportable by IBM in the AIX V4 or V5 reference manuals
  • Undocumented AIX internal features
  • X11R5 Server Extensions
  • Locales based on IBM-850 codesets

Applications compiled on AIX V5.2 will not operate properly on systems running any level of AIX V5.1.

Any program that must run in all environments — POWER3, POWER4, and PowerPC (601 and newer PowerPC processors) — must be compiled using the common mode or PowerPC option of the compiler. Programs compiled to exploit POWER4 technology must be run on the same processor type. Programs compiled to exploit POWER3 technology may be run on POWER3 or POWER4 processor types, though there may be some performance penalty when running on POWER4. Programs compiled to exploit PowerPC-based technology must be run on PowerPC-based processors. Existing binaries need not be recompiled to operate on the target processors.

32-bit Applications from AIX V4 Releases: AIX V4.1, V4.2, or V4.3 applications written for RS/6000 POWER3-, POWER4-, and PowerPC-based models can be executed on AIX 5L V5 without recompilation for same and newer models in that processor family (POWER3, POWER4, or PowerPC). Exceptions are applications compiled using POWER3-, POWER4-, or PowerPC-specific compiler options executed on models other than POWER3, POWER4, or PowerPC, respectively, or applications using:

  • Nonshared compiles of AIX shared libraries
  • Features explicitly described as nonportable by IBM in the AIX V4 or V5 reference manuals
  • Undocumented AIX internal features
  • X11R5 Server Extensions
  • Locales based on IBM-850 codesets

Applications compiled on AIX V5 will not operate properly on systems running any level of AIX V4.

Any program that must run in all environments — POWER3, POWER4, and PowerPC (601 and newer PowerPC processors) — must be compiled using the common mode or PowerPC option of the compiler. Programs compiled to exploit POWER4 technology must be run on the same processor type. Programs compiled to exploit POWER3 technology may be run on POWER3 or POWER4 processor types, though there may be some performance penalty when running on POWER4. Programs compiled to exploit PowerPC-based technology must be run on PowerPC-based processors. Existing binaries need not be recompiled to operate on the target processors.

AIX V5 Binary Compatibility — 64-bit Applications from AIX V4 Releases: Any 64-bit applications produced using AIX V4 will not execute on AIX V5. These applications need to be recompiled from the source on AIX V5 to execute on this version of AIX. The 64-bit applications produced using AIX V5 on any of the 32-bit or 64-bit processor models will execute without recompilation on the 64-bit processor models. The 32-bit applications produced using AIX V5 on either 32-bit or 64-bit processor models will execute without recompilation on both models.

X11R5/X11R6 Compatibility Issues On AIX V5: The AIX V5 X-server uses the X-Consortium release 6 of X (commonly known as X11R6). The libraries shipped by IBM with X11R6 are backward-compatible and the client applications that access these libraries work as on AIX V4. As on AIX V4, IBM will also ship X11R3, X11R4, and X11R5 compatibility installation options for maximum flexibility.

The majority of applications using X fall into this category and will not cause any difficulty. However, a small number of X-applications use the loadable extension facility provided by the X-server.

The X-server allows for the addition of new functionality through its extension mechanism. For each extension, part of the extension is loaded into the X-server before it can be executed. X11R6 has modified how this mechanism works in the course of improvements to X, and it is this part of the extension that must be made compatible with X11R6 to execute properly. All extensions supplied by IBM have been made compatible. In some circumstances, you may have an extension that does not work with X11R6; for example:

  • Sample extension downloaded from the X-Consortium FTP site
  • Customer-developed extension
  • Third-party extension

In these cases, the extension needs to be made compatible with X11R6 before it executes properly. Customer-developed extensions and sample X-consortium extensions need to be recompiled with the X11R6 environment. For third-party extensions, contact the vendor for a X11R6-compatible update.

If you use non-IBM display adapters, you may also be using vendor-supplied software specific to those devices that uses X11R6 server capabilities. If so, this software must be compatible with X11R6 to operate properly. Contact the vendor of the display adapter for this software.

IBM plans to provide a porting guide with AIX V5 to assist customers and vendors who develop adapters or extensions for AIX.

From AIX V3 to V5: All AIX applications using AIX V3R3.2 or later, for POWER-, POWER2-, and PowerPC-based models that are written in accordance with the guidelines in this announcement and other AIX announcements run on AIX V5 without recompilation for those same models. Exceptions are applications compiled using POWER2- or PowerPC- specific compiler options but run on models other than POWER2 or PowerPC, or applications using the following:

  • Their own loadable kernel extensions
  • Certain high-function terminal control interfaces
  • X11R3 input device interfaces
  • CIO LAN device driver interface
  • SCSI device configuration methods (IHVs)
  • The nlist() interface
  • DCE threads

Applications created on a system using AIX V5 may not function properly on a system using AIX V3. Applications must have been created using the AIX shared libraries for these binary compatibility statements to apply.

Limitations: AIX V5.2 is not supported on the RS/6000 SP system at this time, nor on any PSSP-based cluster of servers. Refer to the Statement of Direction for additional information.

AIX Developer Kit, Java Technology Edition, V1.1.8 and AIX Developer Kit, Java 2 Technology Edition, V1.3.0 are not supported on AIX V5.2. Refer to the Statement of Direction for additional information.

Performance Considerations

From AIX V5.1 to V5.2: AIX V5.1 applications written for RS/6000 POWER3-, POWER4-, and PowerPC-based models can be executed on AIX 5L V5.2 without recompilation for the same and newer models in that processor family (POWER3, POWER4, or PowerPC). Exceptions are applications compiled using POWER3-, POWER4-, or PowerPC-specific compiler options but executed on models other than POWER3, POWER4, or PowerPC, respectively, or applications using:

  • Nonshared compiles of AIX shared libraries
  • Features explicitly described as non portable by IBM in the AIX V4 or V5 reference manuals
  • Undocumented AIX internal features
  • X11R5 Server Extensions
  • Locales based on IBM-850 code set

Applications compiled on AIX V5.2 will not operate properly on systems running any level of AIX V5.1.

Any program that must run in all environments — POWER3, POWER4, and PowerPC (601 and newer PowerPC processors) — must be compiled using the common mode or PowerPC option of the compiler. Programs compiled to exploit POWER4 technology must be run on the same processor type. Programs compiled to exploit POWER3 technology may be run on POWER3 or POWER4 processor types, though there may be some performance penalty when running on POWER4. Programs compiled to exploit PowerPC-based technology must be run on PowerPC-based processors. Existing binaries need not be recompiled to operate on the target processors.

Ordering Information

New Licensees

License entitlement for AIX 5L V5.2 is based on the maximum number of processors within a system, including SP systems that are based on the number of processors in each node. For example, a system ordered with a four-processor configuration will be licensed for use on four processors.

Upgrades

Upgrades from previous versions of AIX to AIX 5L V5.2 are only available through Enhanced AIX Operating System Subscription (5771-AIX or 5773-AIX) or, if entitled by contract through:

  • Software Subscription for AIX (5692-SSO)
  • Software Upgrade Protection Plan for AIX and UNIX Operating System Based Software (5692-ADV)

License upgrade charges under Enhanced AIX Operating System Subscription are based on the number of active processors to be used within a system, including SP systems that are based on the number of processors to be used in each node. For example, an SP system originally purchased or leased with four nodes, which has four processors on each node, with AIX V4 used on all four processors on the nodes, would require a specified quantity of 16 processors for the AIX 5L V5.2 license upgrade under 5771-AIX or 5773-AIX.

Current Licensees of AIX

Current licensees of AIX can select from several options to order the latest upgrade to AIX 5L V5.2.

Customers with Valid Enhanced AIX Operating System Subscription Contracts: Customers with valid contracts and who purchased protection for AIX V4.3 or AIX 5L V5.1 under Enhanced AIX Operating System Subscription (5771-AIX or 5773-AIX) are entitled to receive the latest upgrade to AIX 5L V5.2 at no charge. Eligible customers are encouraged to order MES upgrades by calling 800-879-2755. Before you call this number, IBM Software Delivery and Fulfillment (SDF) requires all AIX licensed programs installed on any RS/6000 or pSeries hardware be installed for your appropriate hardware and software serial numbers on AAS. If these conditions are met, SDF will enter an order and will process the installation of the MES. The hours of operation are Monday through Friday, 7:00 a.m. to 4:00 p.m. mountain time.

SDF requests the following information from the caller:

  • Verification of customer name and number.
  • Verification of ship-to address (for a permanent address change, the local IBM office must be contacted).

    Examples of changes that SDF will make are:

    • Number of software shipments to be generated
    • RS/6000 or pSeries hardware and software systems serial numbers
    • Expected shipment/receipt date
    • Expedited software delivery requests

The local IBM office is responsible for:

  • Permanent address change
  • New chargeable software order requests
  • Software discontinuance
  • System program order (SPO) consolidations

If SDF is unable to fulfill a request, SDF will refer you to an IBM representative or to contact your IBM Reseller and request that an MES order be processed to add the applicable media supply feature numbers from the table below under your existing 5771-AIX or 5773-AIX record.

Expedite shipments will be processed to receive 72-hour delivery from the time IBM Software Delivery and Fulfillment (SDF) receives the order. SDF will then ship the order via overnight air transportation.

SPO 5692-A5L: A 5692-A5L SPO is mandatory for shipments of program distribution and publications. The individual licensed program orders (for example, 5765-E62) are for registration and billing purposes only. No shipment occurs under these orders.

To receive shipment of machine-readable materials on CD-ROM requires an SPO 5692-A5L order. Billing for the media is generated under the SPO. To prevent additional billing expenses, place only one SPO order per machine unless requesting multiple releases of the AIX 5L operating systems to support an LPAR environment.

Select the following 5692-A5L feature number for the licensed program hardcopy entitled publications.

Preinstall: The preinstall option is only valid if accompanied by a hardware system order for the preinstalled AIX 5L V5.2 operating system specifying the preinstall option.

It is recommended that backup media be chosen with preinstalled orders. Not all of the software offered under the licensed program will be preinstalled on the system disk. To take delivery of backup media, media feature 3410 must be specified. Software preinstalled on the hard disk does not include all of the function included on the media.

The 5765-E62 order and SPO 5692-A5L must be for the same system type/system number and must have the same scheduled shipment date.

Feature number 5005 must be specified under the individual licensed program 5765-E62 and the 5692-A5L SPO to facilitate preinstall of the licensed program on the system disk.

In addition to feature numbers 5005 and 0947 for preinstall of AIX under SPO 5692-A5L, you must select the appropriate "preinstall designation feature" from the table below.

Software Ordering Instructions for Multiple AIX Operating Systems for LPAR Machines: With the availability of AIX 5L V5.2, IBM offers two operating system releases that support logical partitioning of LPAR-capable hardware. With this initial offering you can order both operating system releases for the same machine, but only one of the operating systems can be preinstalled. When the machine is preinstalled by manufacturing, it is preinstalled in SMP mode, requiring customers who run logical partitions to reinstall.

Order Structure: For LPAR-capable machines to be used in the LPAR-mode, you can order both AIX 5L V5.1 and 5.2 for the same system during initial order creation. Only one of the AIX operating systems can be preinstalled at this time. The applicable preinstall designation feature must be specified on the AIX 5L SPO 5692-A5L containing the AIX release being requested for preinstall. A second AIX 5L SPO 5692-A5L order is required to take delivery of the other AIX release being requested. Media charges apply to both SPO orders if media is requested. To order multiple releases of AIX for LPAR installation, you must also select either the one-year (5771-AIX) or three-year (5773-AIX) Enhanced AIX Operating System Subscription offering.

For LPAR preinstalled systems built in Rochester for U.S. delivery, feature 3483 must be included on the SPO 5692-A5L order that is not being preinstalled to take advantage of single pallet delivery if media and publications are requested.

For Authorized Assemblers, feature number 7305 must be specified under the individual licensed program 5765-E62 and the 5692-A5L SPO to facilitate preinstall of the licensed program on the system disk. In addition to feature number 7305 for preinstall of AIX under SPO 5692-A5L, you must select the appropriate "preinstall designation feature" from the table below.

It is recommended that backup media be chosen with preinstalled orders. Not all of the software offered under the licensed program will be preinstalled on the system disk. To take delivery of backup media, a media feature must be specified. Software preinstalled on the hard disk does not include all of the function included on the media.

The 5765-E62 order and SPO 5692-A5L must be for the same system type/system number and must have the same scheduled shipment date.

The preinstall feature number must be specified under the individual licensed program 5765-E62 and the 5692-A5L SPO to facilitate preinstall of the licensed program on the system disk.

In addition to feature numbers for preinstall of AIX under SPO 5692-A5L, you must select the appropriate preinstall designation feature from the following table.

Optional Preinstall 64-Bit Kernel for                       0963
 for AIX 5.2

The preinstall option is available at no additional charge.

Single Pallet Delivery: Single pallet delivery consolidates pSeries hardware, AIX 5L V5 or V4.3 and selected AIX licensed program orders into a single delivery when preinstall is selected. Programs that are shipped on AIX 5L V5 SPO will have their entitled publications and media consolidated with the pSeries system unit into a single delivery. The software orders affected are those programs ordered with the AIX 5L V5 SPO.

Products Currently Not Supported on AIX 5L V5.2

Licensed program products currently supported on AIX 5L V5.1 that are not offered during order creation using ECFGRS6000 or PCRS6000 when AIX 5L V5.2 is selected for the AIX operating environment, may not currently be supported on AIX 5L V5.2.
