Description

Resource management

AIX 5L V5.3 supports micro-partitioning which enables flexible and efficient use of system hardware resources by allowing physical processors to be shared by up to 10 separate LPARs. IBM eServer pSeries® micro-partitioning support is provided for POWER5 processor-based systems by means of the Advanced POWER Virtualization feature.

Among the key customer environments where micro-partitioning is beneficial are ones in which multiple system images are needed due to isolation requirements (security, software fault), each with generally low processor requirements, but capable of requiring more. Historically, each of these system images ran on separate hardware systems, each able to handle spikes in processor requirements, but generally each hardware system was underutilized. Micro-partitioning enables these system images to be consolidated onto a single set of physical processors, which allows more efficient use of hardware resources. The Advanced POWER Virtualization hardware feature is required to run virtualization on eServer p5 servers.

Advanced accounting provides a framework in which chargeback and capacity planning activities can be performed. Advanced accounting produces resource usage-based information for processes, file systems, transactions, and hardware resources like processors, memory, disks, and network adapters. Applications and middleware may be instrumented to provide transaction data by means of APIs which are provided for this purpose.

Network File System (NFS)

NFS V4 adds support for core features of the NFS V4 protocol described in IETF RFC 3530. This initial support places an emphasis on security with support of the optional NFS V4 ACL model when using the AIX Enhanced Journaled Filesystem. Support for managing accesses from foreign NFS V4 domains is also included. The NFS V4 provided RPCSEC-GSS RPC authentication flavor supporting the Kerberos V5 security mechanism (may also be used with the NFS V3 protocol).

Reliability, availability, and serviceability

The dump command has been enhanced to support the following:

  • ISVs with custom scripts to collect their custom problem data as part of the snap process.
  • Splitting large outputs into smaller files for ease of transport
  • Extended system failure status information captured as part of the dump success, or failures

    Dump compression is turned on by default.

System trace facility has been enhanced to support process and thread-based tracing. You can restrict the tracing to a process and capture the events in relation to the process for better debugging. Also the trace mechanism supports setting of larger trace buffers for regular users.

Support for better core file management has been implemented. A command provides for management of location of core files.

Refer to the command documentation for more detail on the trace, trcctl, chcore, sysdumpdev commands.

Enterprise storage management

Enterprise storage management tools include:

  • JFS2 to handle extended ACL attributes and finer grain permissions in order to support NFS V4.
  • Support will be provided to limit filesystem space to a specified quota for users and/or groups.
  • AIX support will enhance concurrent mode that allows only a single host to open logical volumes with write access, thus creating an owning host. Support is added to change the owning host so that on failover reserves are not broken on all disks in the volume groups. HACMP™ would use these to start a volume group and fail it over to another node.
  • AIX support to include the limit on the number of disks in a volume group from 128 to 1024.

LVM enhancements are designed to:

  • Provide ability to shrink a JFS2 filesystem in place
  • Improve LVM HotSpot Management
  • Increase I/O throughput via LVM Large Block I/Os
  • Implement scalable volume group types

Systems management

Service Update Management Assistant (SUMA) will provide flexible options that will automate the download of AIX APARs, PTFs, Security Fixes, Latest Fixes, and Maintenance Levels from the IBM eServer Support Fix Central Web site, and move administrators away from the task of manually retrieving maintenance updates from the Web.

When performing remote execution on clients, NIM makes use of the remote shell server (rshd). The server provides remote execution facilities with authentication based on privileged port numbers from trusted hosts. AIX 5L V5.3 has a new service, NIM Service Handler (nimsh), which will eliminate the need for rsh services during NIM client communication.

Cluster Systems Management (CSM) V1.4 is designed for simple, low-cost management of distributed and clustered IBM eServer, pSeries, and xSeries® servers. For organizations with both Linux and AIX applications, a single AIX 5L V5.2 or V5.3 management console can provide management services to AIX 5L and Linux clients in distributed and clustered configurations.

System security

System administrator can setup AIX for supporting long user names (longer than the traditional user name size of 8 characters) for up to 255 characters. The default limit will continue to be eight characters. Refer to chdev command security guide for additional information. Various functions of the operating system have been enhanced to recognize the support for greater than 8 character user name size.

Support for Access Control Lists (ACLs) for file system objects have been enhanced. The operating system now provides infrastructure for support of multiple ACL types based on the underlying physical file system. The JFS2 file system continues to support the existing AIX ACL (now called AIXC type for AIX classical ACL) and also a new ACL type, NFS V4. The NFS V4 ACL type provides access control as per the ACL model described in the NFS V4 protocol. Various ACL management tools and file management tools have been enhanced to support multiple types of ACLs on AIX. Refer to Security Guide documentation for additional details.

LDAP based user management infrastructure on AIX has been enhanced to support the following:

  • LDAP server based authentication is supported. This allows system administrator to manage the passwords on the LDAP server using one of many encryption algorithms.
  • Kerberos bind is enabled for LDAP client to server authentication.
  • Increased control over generation of the directory information tree (DIT) when configuring the server with the mksecldap command.

The csum command has been added to help calculate cryptographic hash values for files.

Default maximum number of user logins supported on the system has been increased to 32,767.

NIS infrastructure has been enhanced to support netgroups with LDAP.

The AIX 5L V5.3 NIS client supports the use of shadow passwords in a passwd.adjunct file. The primary benefits are increased security for NIS environments and increased interoperability with Solaris NIS infrastructure.

Development and performance tools

AIX 5L V5.3 improves dbx application debugging capabilities including additional facilities for examining process information, file descriptors, kernel threads, and core files, as well as new functionality for suspending breakpoints and managing loaded modules.

AIX 5L V5.3 introduces a new memory allocation algorithm, MALLOCTYPE=watson. The Watson malloc() setting can provide improvement over the default malloc in areas of memory fragmentation and performance in massively multi-threaded applications, particularly with respect to small requests. New features have been added to the malloc debugging facility to aid in the diagnosis of memory allocation problems, and malloc debugging capabilities have been integrated into the dbx symbolic debugger.

Added support for using copy-on-write semantics for fork(). This implementation helps reduce overall virtual memory consumption on a system and improve fork() as well as exec() performance for some workloads.

New performance tools are added to AIX 5L V5.3. Enhancements to performance tools and libraries supporting new POWER5 and PowerPC processors have been included as well as micro-partitioning and Simultaneous Multi-threading (SMT).

The following programs are the fully supported versions:

  • VisualAge® C++ Professional for AIX, V6.0
  • C for AIX, V6.0
  • XL Fortran for AIX, V8.1.1

The IBM 32-bit SDK for AIX, Java™ 2 Technology Edition, V1.4 ships with AIX 5L V5.3. The IBM 64-bit SDK for AIX, Java 2 Technology Edition, V1.4 is available on the AIX 5L V5.3 Expansion Pack and the AIX Java Web site

Click on the download and service information link. For more information, consult the User's Guide which is available from the AIX Java Web site.

Performance Toolbox V3.1

Performance Toolbox (PTX) V3.1 adds support for new pSeries Partition Load Manager and Advanced POWER Virtualization technology.

On system running Partition Load Manager, PTX can monitor special load/utilization averages, active processor counts and memory allocations that control the operation of the Load Manager. This allows customers to visualize the system performance as Partition Load Manager dynamically controls and adjusts resources to the system workload. For Advanced POWER Virtualization, the PTX instrumentation can now collect over 30 new performance metrics related to SMT and micro-partitioned environments. These metrics include processor allocations (logical, physical, virtual counts, and capacities), memory allocations and capacities, and defined partition entitlements. The PTX jtopas and 3dmon applications have been updated to provide views of the new Advanced POWER Virtualization metrics.

The 3dmon application will automatically identify the set of partitions residing on the same pSeries hardware platform. Multiple partitions can be viewed simultaneously in relationship to one another, for an overall view of system utilization. Changes in partition allocations are dynamically discovered and displayed for monitoring, recording, and playback.

The Performance Aide V3.1 fully supports the collection and recording of the new Partition Load Manager and Virtualization metrics identified above.

Network technology and communications

  • The AIX multi-path routing capability has been extended to add new schemes, besides round-robin, for route selection which would allow for more fine-grained control of the route selection policy.
  • The AIX Path MTU discovery mechanism discovers PMTU using TCP packets and UDP datagrams rather than using extra ICMP packets.
  • Support has been added for the Advanced Sockets API for IP V6.
  • Support has been added for the Streams Control Transmission Protocol (SCTP) in AIX.
  • AIX now supports Dynamic Host Configuration Protocol (DHCP) for IPV6 as described by RFC 3315.
  • Dynamic membership in EtherChannel support allows users to add or remove an adapter from a running EtherChannel without having to first detach its interface. This is useful when hot-swapping adapters that belong to an EtherChannel.
  • AIX supports TCP/IP over Fibre Channel interface (IP over FC). This is the AIX implementation of IETF's RFC 2625, which specifies encapsulation of IP and Address Resolution Protocol (ARP) over Fibre Channel (FC).

Network interoperability

AIX Fast Connect V3.2.0 offers the following enhancements:

  • Implementation of directory change notification
  • Support of direct hosting of Server Message Block (SMB) over TCP/IP
  • Implementation of level II oplocks
  • Support of large files
  • Support of 32-bit Microsoft™ Windows NT™ status codes
  • Implementation of SMB signing
  • Support of long user names
  • Support of complete Microsoft Windows NT ACLs and ACL inheritance
  • Dynamic user creation on AIX

Base operating system

System libraries and headers incorporate APIs from the ISO/IEC 9899:1999 C language standard and the single UNIX specification Version 3.

A device mount facility, explicitly enabled, provides a mechanism to mount CD and DVD filesystems. The facility is included in the bos.cdmount fileset.

The Perl V5.8.2 language is installed with AIX.

System V proc commands display information in the /proc filesystem in the System V format.

AIX 5L V5.3 provides new functionality in base commands including tree-based process listing, timestamped shell histories, cron logging controls, recursive file searching, restricted Korn shells, tar recursion control, new date formats, and vi backtagging, as well as other new capabilities for the make, find, fuser, restore, man, tar, at, nohup, and cron commands. The awk, ed, grep, head, and vi commands can now process lines of at least 8192 characters.

IBM eServer BladeCenter JS20

The recently announced POWER processor-based IBM eServer BladeCenter JS20 will support AIX 5L V5.2 effective August 20, 2004. This enables customers to consolidate and integrate AIX-based applications such as database, IT infrastructure, e-mail, and Web serving onto the BladeCenter platform. With its low price point the IBM eServer BladeCenter JS20 is IBM's entry level POWER processor-based product into the AIX market.

Models 8842-21x are supported on the eServer BladeCenter JS20. eServer BladeCenter JS20 is in AIX 5L processor group classification E5. The quantity of AIX 5L V5.2 licenses ordered for use on either single or multiple BladeCenter JS20s must be equal to the number of processors on which the AIX 5L V5.2 is intended to be used at a single end user customer (single IBM customer number) location. Additionally, ordering of AIX 5L V5.2 (processor group E5) licenses for BladeCenter JS20 require order placement for either a one-year or three-year SWMA for AIX 5L Operating Systems contract at the same time of order placement for AIX 5L V5.2 licenses. Neither AIX 5L V5.2 licenses nor SWMA for AIX Operating Systems contracts (processor group per processor usage) are included in the eServer BladeCenter JS20 offering price.

Accessibility by people with disabilities

Using AIX documentation

The AIX product documentation library is available online at

The information center is accessible through assistive technologies, such as screen-reader software and digital speech synthesizers, to hear what is displayed on the screen. In addition, features of the information center can be accessed through the keyboard. The AIX man pages are available from the command line and are accessible through 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 System Management Interface Tool (SMIT)

Web-based System Manager supports keyboard accessibility for almost all operations available from the graphical user interface. Limited support for changing font sizes and background colors is also available. Screen reader support in the Web-based System Manager Remote Client is significantly improved in this release. Refer to the README file for more information. The Configuration Assistant (invoked via the configassist command) has also been modified to provide improved accessibility support in this release.

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.

Section 508 of the U.S. Rehabilitation Act

IBM AIX 5L for POWER V5.3 is capable as of August 20, 2004, when used in accordance with IBM's associated documentation, of satisfying the applicable requirements of Section 508 of the Rehabilitation Act, provided that any assistive technology used with the product properly interoperates with it.

Statement of direction

Withdrawal of support for AIX 32-bit kernel in AIX 5L V5.4

AIX 5L V5.3 is the last release of AIX that will support the 32-bit kernel. Future releases of AIX, beginning with AIX 5L V5.4, which is scheduled for availability in fourth quarter 2006, will only support the 64-bit kernel. The AIX 5L V5.4 64-bit kernel will continue to support 32-bit applications, but will not support 32-bit kernel extensions or device drivers.

Applet mode of Web-based System Manager

IBM will remove the ability to manage AIX systems via the Applet mode of Web-based System Manager in future releases. Remote system management will continue to be supported via the remote-client and Java Web Start functions. Current users of Applet mode will find that Java Web Start offers enhanced performance and stability compared to Applet mode. The recommended method for remote management of AIX systems using Web-based System Manager is Java Web Start, which is enabled for all supported Web-based System Manager configurations. AIX 5L V5.3 will be the last release to support Applet Mode for the Web-based System Manager.

Kerberos support on PSSP

Support for Kerberos V4 used by PSSP software on SP systems will be withdrawn with AIX 5L V5.4, which is scheduled for withdrawal in fourth quarter of 2006.

Windows 95 client on Fast Connect

The support of Windows 95 client on Fast Connect will be withdrawn with the AIX 5L V5.4, which is scheduled for withdrawal in fourth quarter 2006.

Support for cluster licensed programs

IBM intends to provide support for the following cluster licensed programs on AIX 5L for POWER V5.3 only in a switchless environment in fourth quarter 2004:

  • Engineering and Scientific Subroutine Library for AIX 5L
  • Parallel ESSL for AIX 5L
  • General Parallel File System for AIX 5L
  • LoadLeveler® for AIX 5L
  • Parallel Environment for AIX 5L
  • High Availability Cluster Multi-Processing for AIX 5L

Sub-capacity licensing for middleware products

To continue to lead the industry in developing On Demand Business solutions, IBM intends to provide flexible pricing and financing that enable clients to exploit new technology. IBM has already taken important steps in this area with the announcement of complementary On/Off Capacity on Demand offerings for hardware and software.

IBM considers sub-capacity licensing to be a strategic offering within the on demand portfolio. Sub-capacity licensing enables the licensing of software products for use on less than the full capacity (in processors) of the machine when used within a logical partition. IBM currently offers sub-capacity licensing for selected software, including WebSphere® Application Server running on IBM eServer iSeries™.

Within the next twelve months, IBM intends to announce sub-capacity licensing terms and conditions for additional middleware products, such as WebSphere Application Server and DB2® Enterprise Server Edition, on other platforms such as AIX 5L, i5/OS, OS/400®, and Linux on POWER. IBM also plans to deliver license management tools to assist clients in tracking and reporting their software assets to take advantage of these flexible pricing models. Contact an IBM sales representative for details.

All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only. Contact your local IBM office or IBM authorized reseller for the full text of a specific Statement of General Direction.

Resource management

Advanced accounting supports tagging of the accounting data with system administrator-defined strings, so that the billable entity can be directly associated with accounting data. This is accommodated through system administrator-defined policies, which are downloaded into the kernel. The policy mechanism supports the manual assignment of project codes so non-privileged users with multiple clients can easily switch back and forth between a controlled set of projects. APIs are also provided, so application-defined projects can be established. This is required for on demand and cluster computing environments where the set of users is very fluid.

Advanced accounting also supports interval accounting, which may be used to profile the use of system resources and capture accounting data for long running jobs. Interval accounting is an important tool for capacity planning, performance analysis, and billing.

Advanced POWER™ Virtualization supports virtual Ethernet as an in-memory, point-to-point connection to help avoid a failed or misbehaving operating system from being able to impact the communication between two well-behaved operating systems. Each pair of partitions wishing to communicate through this channel will need to create an additional in-memory channel. This will require the ability for a user to request the creation of an in-memory channel between partitions on the hardware system console. The kernel would create a virtual device for each memory channel indicated by the firmware. A normal AIX® configuration routine would create the device special files. This function is supported only on future systems with POWER Hypervisor function.

Virtual Storage, supported via the Advanced POWER Virtualization hardware feature, facilitates the sharing of physical resources (I/O slots, adapters and devices) between logical partitions (LPARs). Virtual SCSI (VSCSI) enables partitions running on AIX 5L V5.3 to access SCSI disk devices without requiring physical resources be allocated to the partition.

Advanced POWER Virtualization partitions maintain a client/server relationship in the VSCSI environment. Partitions that contain virtual SCSI devices are referred to as client partitions while the partitions that own the physical resources (adapters, devices) are the server partitions. AIX 5L V5.3 supports booting from virtual SCSI disks.

A fairly common business model is to allocate a partition to a single account and to charge only for the resources that are actually used. Interval accounting supports this model by collecting system level resource utilization information for processors, memory, network adapters, and disks. The accounting subsystem is highly tuned to efficiently deal with large amounts of data. For example, the subsystem internally buffers accounting data and uses asynchronous I/O to write to the accounting file, which is pre-allocated to ensure that disk blocks are contiguously allocated. The system administrator can also configure advanced accounting in different ways to minimize the overhead of running advanced accounting. The administrator can select the type of accounting data to be collected and can specify that it should be automatically aggregated to minimize the volume of data that is produced.

Modern wide issue superscalar processors have the ability to execute numerous instructions in a single cycle. However, the execution of single real life code sequences rarely comes close to using the full bandwidth of these processors.

Scalability

AIX 5L V5.3 supports Simultaneous Multi-threading (SMT) which is a processor technology that allows the simultaneous execution of multiple thread contexts within a single processor core.

SMT offers a way to leverage the parallelization of multi-threaded software to achieve a higher use of the processor by dispatching instructions from more than one instruction stream simultaneously.

To the operating system, each hardware thread is treated as an independent logical processor. The result is a natural mapping of the existing SMP capabilities of the operating system to the multi-threaded execution capabilities of the processor. There are two hardware threads per processor. System administrators may enabled or disable SMT at the partition level and it may be used with either dedicated or shared partitions.

  • Dynamic Reconfiguration (DR) support for large pages allows customers to change the size of large page memory without rebooting.
  • The virtual memory pager is enhanced to release paging space blocks earlier, so that paging space may be more efficiently used when a large number of pages have to be paged out at the same time like in a memory removal operation.
  • The memory algorithm is enhanced to page out large blocks of memory. This provides more flexibility for scientific and technical computing and enhances high availability.

Standards

AIX 5L V5.3 is designed to conform to the following:

  • Single UNIX® Specification V3 (SUS V3)
  • ISO/IEC 9899:1999 international standard for the C programming language, commonly referred to as C99.

The service and support terms and conditions of the products shipped on the Expansion Pack may be different than the terms and conditions for AIX 5L V5.3.

Enterprise storage management

Extension to the chfs command will allow a JFS2 filesystem to be shrunk in place, without taking it offline and without requiring a reboot. This will eliminate unused filesystem space. This also includes the Logical Volume Manager (LVM) necessary to shrink a logical volume in place. This implementation replaces the need to copy the data, take the old version offline (which may require a reboot), and delete the old version.

System management

A new RPM Package Manager (RPM) will allow customers to perform network installations of AIX and a limited set of maintenance operations from a Linux™ server.

New support provides basic language enablement and localization for the following languages:

  • TA_IN — Tamil
  • TE_IN — Telugu
  • GU_IN — Gujarati
  • MR_IN — Marathi

Base Operating System Install now offers a choice to have the hard disk being installed to, erased of all data, with selectable erasure patterns. This choice is available for New and Complete Overwrite installs from CD and available for Network (NIM) installs using new variables in the bosinst_data NIM resource. Other disks can be erased by entering the maintenance mode in the BOS Install menus.

Support for multiple NIM masters. Customers will be able to define an alternate NIM master, synchronize the NIM database between masters, and failover between masters. This provides a basic way for customers to create a more reliable NIM environment.

The NIM client daemon will have its service ports registered as well-known ports (3901 and 3902) and will install as part of the bos.sysmgt.nim.client fileset. The daemon will serve two purposes:

  • Receive/process NIM master service requests
  • Receive/process NIM master registration requests by passing machine information necessary for defining a client in a NIM environment

While nimsh eliminates the need for rsh and interactive shell environment access, it does not provide a trusted authentication approach based on key encryption. If users wish to have cryptographic authentication during nimsh usage, OpenSSL may be configured within the NIM environment. When OpenSSL is installed on NIM clients, SSL socket connections are established during nimsh service authentication. Options are provided for SSL key generation and includes all cipher suites supported in SSL V3.

In addition to cryptography options, nimsh allows customers the flexibility of 'querying' network machines by hostname. The NIM Service Handler processes query requests and returns NIM client configuration parameters used for defining hosts within a NIM environment. Using nimsh, customers may define NIM clients without knowing any system or network specific information.

Web-based system manager support for LVMs are enhanced to:

  • Reduce the number of icons used in volume group
  • Clearly show the type of volume group in the properties
  • Suppress inappropriate columns in the volume group sub-plugin
  • Hide FS specific properties in the logical volume plugin

CSM is also a key element of the IBM eServer® Cluster 1600 and Cluster 1350, platforms that are ideal for workload consolidation or for achieving high degrees of scalability and performance for applications that take advantage of clustered systems architectures. Primary examples are computational modeling in high-performance computing or multi-terabyte data warehouses in large corporations.

CSM is enabled on AIX 5L V5.3 on a trial basis. For production use of CSM, obtain a valid license and key by ordering CSM for AIX 5L (5765-F67).

System security

Pluggable Authentication Module (PAM) infrastructure has been enhanced to include additional authentication modules. Use of PAM as an authentication mechanism is now a system wide decision rather than per user. Many native operating system applications have been PAM enabled to recognize this configuration choice.

Even though it is possible to increase or decrease the size of the user name, it is advised that the user name size should never be decreased. However if there is a need to decrease the user name, current user names on the system be studied carefully to make sure that the none of the user have names greater the size being planned to be set. If this is not done, system behavior in regards to login and other functions in regards to these users will be unpredictable.

Tivoli® Security Clients/Agents for pSeries AIX 5L

Tivoli security-ready clients and agents will be pre-installed on pSeries POWER5™ servers running AIX 5L V5.2 beginning in August 2004. Pre-installed Tivoli security-ready clients and agents for pSeries POWER4+™ and POWER4™ servers running AIX 5L V5.2 will also be available beginning in August 2004. IBM intends to pre-install security-ready clients and agents on pSeries POWER servers that support AIX 5L V5.3 in the future.

The Tivoli security clients and agents software when coupled with optional corresponding and extra cost server-based Tivoli security management solution offerings can provide pSeries customers with security capabilities to help address a fundamental and heightened customer need for more secure on demand systems.

Tivoli security (identity) management solutions provide two critical layers of additional defense beyond the traditional perimeter defense provided by firewalls, anti-virus software and intrusion detection software a security control layer and a security policy compliance layer.

The Tivoli control layer determines which server users can access and what users may view and do. The Tivoli security compliance layer helps to ensure that customers are, and remain in, compliance with security policies while helping assess security risk and initiating responses to security events.

The Tivoli security-ready client and agent software available for pSeries POWER5, POWER4+, and POWER4 server with AIX 5L V5.2 is:

  • Client for Tivoli Access Manager for Operating System AIX
  • Agent for Tivoli Identity Manager
  • Agent for Tivoli Risk Manager
  • Client for Tivoli Security Compliance Manager

To use each Tivoli security-ready client or agent, acquisition of the following corresponding server-based Tivoli security management product offering is required.

  • Tivoli Access Manager for Operating System AIX
  • Tivoli Identity Manager
  • Tivoli Risk Manager
  • Tivoli Security Compliance Manager

When pre-installed, the security-ready clients/agents help simplify the implementation and enablement of Tivoli security management solutions. These Tivoli security management solutions enable a consistent enforcement of security management policies across pSeries and AIX 5L as well as across heterogeneous server environments running UNIX, Linux, and Microsoft™ Windows™ operating systems.

Optional Tivoli Security Management Offerings for pSeries AIX 5L

Tivoli security-ready clients and agents for pSeries AIX 5L servers provide the means for Tivoli security management software running on a pSeries AIX 5L server to provide and manage two different layers of security (a control layer and/or a security policy compliance layer) for each connected and enabled server "client." One Tivoli security management server can manage up to thousands of pSeries AIX 5L server "clients." Security management capabilities include:

  • Secure and manage the pSeries AIX 5L server : Tivoli Access Manager for Operating System AIX is optional extra cost server-based enablement software that provides multiple pSeries AIX 5L server clients with IBM main-frame class security. Access Manager can lock down and harden the AIX 5L operating system at the root level thereby helping to secure applications and protect data, meet customer security audit requirements and reduce security administration costs.
  • Setup and manage the users : Tivoli Identity Manager is optional extra cost server-based enablement software that automates the creation and management of multiple user accounts. Identity Manager helps to significantly shorten the time for provisioning users from weeks to minutes and automatically discovers invalid user accounts.
  • Manage security operations : Tivoli Risk Manager is optional extra cost server-based enablement software that centrally monitors, reports and manages security events. Risk Manager helps to radically improve the administration of the whole security management environment.
  • Audit security policies for compliance : Tivoli Security Compliance Manager is optional extra cost server-based enablement software that checks the server system, middleware and applications for vulnerability and adherence to customer security policies. Security Compliance Manager determines violations against security policies that are provided by IBM or modified or written by the customer.

Complementary (security) offering — Tivoli Directory Server

Store users and their identities : Tivoli Directory Server is server-based enablement software. Directory Server is foundation service software for building security-rich and standards compliant identity infrastructure solutions. It provides a robust and light weight directory access protocol (LDAP) and offers a choice of providing simple user ID and password authentication or robust digital certificate-based authentication. Directory Server is provided as a part of the AIX 5L V5.2 Expansion Pack.

Customer value

Tivoli security management solutions for pSeries AIX 5L can significantly help meet the heightened and growing customer need for a more secure on demand IT and server operating environment.

Tivoli security-ready client and agent software provides customer value when pre-installed. Pre-installation with AIX 5L will help save installation planning and implementation time when the clients/agents are security enabled by Tivoli security management (server) offerings.

Significant additional customer value is provided when the Tivoli security-ready clients/agents are connected to and enabled by Tivoli security management (server) software:

  • Helps protect and optimize IT resources by controlling "who has access to what"
  • Helps reduce the cost of security administration and support
  • Helps manage complexity with a single user sign-on and unified user experience
  • Helps validate compliance against security policies and audits requirements

IBM value

SOSWOS (Sell Our Stuff With Our Stuff)... Tivoli security-ready clients/agents and Tivoli security management solution offerings help to further differentiate the value of pSeries and AIX 5L when compared to UNIX-based competitors such as HP and Sun Microsystems. HP and Sun do not have the security management solution portfolio capabilities of IBM. When marketed and sold together as an integrated security management solution, pSeries, AIX 5L and Tivoli is a winning combination.

Development and performance tools

The following performance tools and libraries have been enhanced:

  • PMAPI library now supports threaded applications running in M to N mode, and the new POWER5 and PowerPC970 processors.
  • The perfstat library, and the vmstat, iostat, sar, topas, curt, and splat tools have been enhanced to support micro-partitioning and SMT. Filemon, netpmon, and pprof have been enhanced to support micro-partitioning. Support for SMT will be added to those three tools in a future release.
  • Iostat, vmstat, and sar now detect and tolerate dynamic configuration changes
  • Using the -d option of the sar command, average queue size, and service and wait time can now be monitored for selected disk types.
  • The gprof tool now supports multi-process and multi-threaded applications
  • Trace now support single process and thread tracing.

The following new tools are available:

  • Lparstat which displays partition configuration information and allows monitoring of a set of partition level performance metrics.
  • Mpstat which can be used to monitor a large set of detailed performance metrics at the logical processor level

Network technology and communications

Additional route selection policies will include Random, Weighted Random, Lowest Utilization, Weighted Round-Robin, and Hash based on destination IP address.

The discovered PMTU information is stored in a dedicated table and has a method to manage the table. Separating the PMTU and the routing table makes multi-path routing work better with PMTU discovery.

Wake on LAN® technology is used to remotely wake up a machine by sending the machine a specific packet of information, called a Magic Packet. AIX provides a command (wol) to construct and send a Magic Packet frame to wake up a remote machine.

Upgrades to the AIX tcpdump and the libpcap library improve the network traffic debugging capabilities of AIX.

Support has been added for the Service Location Protocol client side API on AIX. Service Location Protocol is described by RFC 2608 and the client side API is described by RFC 2614.

New functions include socket options, ancillary data, library functions, macros to manipulate ancillary data, structure, and constant definitions based on the RFC standard 3542.

Support has been added for the Streams Control Transmission Protocol (SCTP) in AIX. SCTP is a reliable transport layer protocol which runs over IP and is described in RFC 2960. A socket API for applications to communicate using SCTP is also provided.

Support is provided for both the DHCP server (dhcpsdv6) and client (dhcpcdv6) and retains much of the flexibility and ease of configuration that users are accustomed to in the AIX DHCP for IP V4. The DHCP relay agent (dhcprd) has been enhanced to support both IP V4 and IP V6 environments.

AIX TCP/IP remote commands continue to support Kerberos V5 for authentication. Support for Kerberos V4 used by PSSP software on SP systems will be withdrawn.

Fibre Channel is a high-speed, networking technology primarily used for Storage Area Networking (SAN). Currently with AIX, Fibre Channel is only used for communication between storage devices and servers using the SCSI protocol (FCP). This AIX feature adds the support to enable IP packets to be sent over a physical Fibre Channel connection as well. When a Fibre Channel adapter's IP protocol driver is configured and the IP over FC properties are assigned, the Fibre Channel adapter may also be used as a LAN device. Its network activity will function just as if an Ethernet or Token-Ring adapter were being used. In a SAN environment, this will allow servers and storage systems to communicate and perform networking type of management services without additional LAN equipment and infrastructure.

IP over FC is only supported on the IBM 2 Gigabit Fibre Channel Adapter for 64-bit PCI Bus (#6228) and the IBM 2 Gigabit Fibre Channel PCI-X Adapter (#6239) with the configuration of an IP enabled Fibre Channel switch. The Fibre Channel switches that have been verified to work with this feature are: both 1 GB and 2 GB Fibre Channel switches manufactured by Brocade and Cisco.

AIX EtherChannel feature allows Ethernet bandwidth aggregation from several Ethernet adapters. EtherChannel feature is currently available. Dynamic Membership feature allows systems administrators to add or remove adapters from a running EtherChannel and change EtherChannel attributes except Ethernet frame size without having to first detach its interface. This enables the dynamic reallocation or deallocation of adapters, particularly useful when hot-swapping adapters that belong to an EtherChannel.

The maximum number of Fibre Channel logical units supported per target was increased from 1023 to 4095 in AIX 5L V5.2. In FC, each end point is referred to as an N_Port. If that N_Port supports SCSI protocol, then it is also referred to as a target. Each target is composed of one or more logical units.

The iSCSI protocol driver is included as part of AIX Base Operating System. It allows the access of storage devices over gigabit Ethernet TCP/IP networks. The iSCSI driver has been verified to work with the Cisco MDS 9000 IPS module as the iSCSI target, using IBM TotalStorage® ESS F20 and IBM TotalStorage ESS 800 storage devices.

The current iSCSI driver is based on IETF RFC 3720 iSCSI standard, with certain limits and functional limitations as described in AIX 5L V5.2 and AIX 5L V5.3 release notes.

The configuration of EtherChannel and Virtual IP Address (VIPA) network interfaces will be added to the NIM secondary adapter support.

Network interoperability

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

  • Implementation of directory change notification support to improve the performance of the server. Some applications like biztalk can be installed on Fast Connect shares with this feature.
  • Support of direct hosting of SMB over TCP/IP (aka NetBIOS-less connection support). It simplifies the transport of SMB traffic, removes WINS and NetBIOS broadcast as a means of name resolution and standardizes name resolution on DNS for file and printer sharing.
  • Implementation of level II Oplocks helps improve the performance of the server by allowing multiple clients to access files in Read/Deny-Write lock-mode.
  • Support of large files, large sends and large receives are added. Now Fast Connect can handle the file sizes and file offsets supported by AIX.
  • Support of 32-bit NT status codes is added, which improves the communication between server and client and supports newly defined return codes.
  • Implementation of SMB signing in Fast Connect supports mutual authentication of client and server, reduces the "man-in-the-middle" attacks.
  • Fast Connect supports long user names, a new feature of AIX 5.3, which can eliminate the Windows to AIX users name mapping.
  • Support of NT ACLs is implemented. Windows clients can add users or groups to grant NT ACL permissions to files/folders of Fast Connect server. The key/basic NT ACLs are supported prior to AIX 5L V5.3 levels, and complete NT ACLs and ACL inheritance are supported on AIX 5L V5.3.
  • Fast Connect users can be dynamically created in passthrough authentication configuration by reducing the administrative overhead.
  • Microsoft Windows 2003 clients are supported, in addition to existing support for Microsoft Windows 98, Windows NT™, Windows 2000, and Windows XP.

New I/O support

AIX 5L V5.3 includes support for:

  • 10 Gigabit Ethernet-SR PCI-X adapter. This adapter is designed to provide LAN connections for pSeries systems. The adapter has a 128 K x 8-bit boot FLASH ROM to support NIM functions.
  • 1.44 MB external USB 1.1 diskette drive with an integrated USB attachment cable.
  • DVD media as a dump device. System administrators can configure a DVD RAM as the dump device and the dump will be written out to the DVD media directly.
  • AIX device driver for ATAPI (IDE) optical for write capability. This is important for support of IDE attached DVD-RAM.
  • 2 Gigabit Fibre Channel PCI-X adapter provides connectivity to fibre channel storage area networks (SANs) as well as boot support from fibre channel attached storage.
  • PCI-X Dual Channel Ultra 320 SCSI adapter provides connectivity to Ultra320 speed SCSI DASD as well as SCSI tape and optical devices.
  • PCI-X Dual Channel Ultra 320 SCSI RAID adapter supports RAID 1,10, and 5 arrays, as well as standard SCSI JBOD disks, tapes, and optical devices. Boot support from a RAID array is supported with this adapter.

AIX 5L V5.3 support removal

The AIX 5L operating system previously contained both a uni-processor kernel and a multi-processor kernel. Effective with this AIX 5L V5.3 release, the operating system will only support the multi-processor kernel. The AIX 5L V5.3 multi-processor kernel will support the following systems: RS/6000, pSeries, or OEM hardware based on the Common Hardware Reference Platform (CHRP) architecture, regardless of the number of processors.

AIX 5L V5.2 will be the last release of AIX that will support the uni-processor kernel.

Compatibility

Applications from earlier AIX V5 releases

AIX 5L V5.1 and V5.2 applications written for RS/6000 POWER3-, POWER4-, POWER5-, and PowerPC-based models can be executed on AIX 5L V5.3 without recompilation for the same and newer models in that processor family (POWER3, POWER4, POWER5, or PowerPC). Exceptions are applications compiled using POWER3-, POWER4-, POWER5- or PowerPC-specific compiler options but executed on models other than POWER3, POWER4, POWER5, or PowerPC, respectively, or applications using:

  • Non-shared 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
  • Legacy security library interfaces executing on AIX V5 systems with long usernames enabled

Any program that must run in all environments — POWER3, POWER4, POWER5, and PowerPC (601 and newer PowerPC processors) — must be compiled using the common mode or PowerPC option of the compiler. Programs compiled to exploit:

  • POWER5 technology must be run on POWER5 processor types
  • POWER4 technology must be run on POWER4 or POWER5 processor types
  • POWER3 technology may be run on POWER3, POWER4, or POWER5 processor types, though there may be some performance penalty when running on POWER4 or POWER5
  • PowerPC-based technology must be run on PowerPC-based processors
Existing binaries need not be recompiled to operate on the target processors.

Applications running on AIX V5 Releases with long usernames enabled

AIX 5L V5.3 systems can be configured to accommodate user and group names exceeding eight characters. Applications which have not been specifically structured to handle long user and group names and which use legacy security library interfaces with 8-character name limits or which depend on user and group names not exceeding 8 characters in length may not work correctly on systems which have been enabled for long user and group names. AIX 5.3 commands which display user and group names will truncate user and group names to 8 characters to accommodate existing use unless command-specific options are utilized to display long user and group names.

Legacy Security               Long Username-Enabled
Library Interface             Alternative
 
ckuserID()                    authenticatex()
cuserid()                     getpwuid()
getuinfo()                    getuinfox()
getuinfo+r()                  getuinfox()
getuserpw()                   getuserpwx()
newpass()                     newpassx()
putuserpw()                   putuserpwx()
putuserpwhist()               putuserpwxhist()

AIX 5L V5.3 systems running applications using security library interfaces should not be configured for long usernames unless the applications have been tested successfully for long username support.

32-bit Applications from AIX V4 releases

AIX V4.1, 4.2, or 4.3 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, POWER5, or PowerPC). Exceptions are applications compiled using POWER3-, POWER4-, or PowerPC-specific compiler options executed on models other than POWER3, POWER4, POWER5, or PowerPC, respectively, or applications using:

  • Non-shared 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
  • Legacy security interfaces executing on AIX V5 systems with long usernames enabled

Programs compiled to exploit:

  • POWER5 technology must be run on POWER5 processor types
  • POWER4 technology must be run on POWER4 or POWER5 processor types
  • POWER3 technology may be run on POWER3, POWER4, or POWER5 processor types, though there may be some performance penalty when running on POWER4 or POWER5
  • PowerPC-based technology must be run on PowerPC-based processors

Existing binaries need not be recompiled to operate on the target processors.

64-bit Applications from AIX V4 releases

Any 64-bit applications produced using AIX V4 will not execute on AIX 5L V5. These applications need to be recompiled from the source on AIX 5L V5 to execute on this version of AIX. The 64-bit applications produced using AIX 5L 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 5L 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, 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.

Between AIX V3 and 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 5L V5 without recompilation for those same models. The exceptions to this statement 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
  • The CIO LAN device driver interface
  • SCSI device configuration methods (IHVs)
  • The nlist() interface
  • DCE threads
  • Legacy security interfaces executing on AIX 5L systems with long usernames enabled

Applications must have been created using the AIX shared libraries for these binary compatibility statements to apply.

Limitations

  • IBM Parallel System Support Programs (PSSP) for AIX is not supported running AIX 5L V5.3
  • SP Switch and the SP Switch2 are not supported running AIX 5L V5.3
  • Partition Load Manager for AIX (available via a hardware feature code of Advanced POWER Virtualization) is not targeted for customers that want to implement very small granularity CPU resource management (micro-partitioning) on shared-processor logical partitions. Memory management is fully supported on these configurations, but CPU management may not always give the desired result.

Ordering information

New licensees

  • AIX 5L V5.3 on POWER5 and POWER4 systems

    License entitlement for AIX 5L V5.3 is based on AIX hardware processor group classification.

    Under each AIX processor group classification E5 and F5, licenses for AIX 5L V5.3 must be purchased/ordered based on the total number of active processors running AIX Operating System. For example, for a machine/type 9117-570 ordered with a four-way processor configuration on which the end user intends to run AIX 5L V5.3 on two of the four active processors, you should order two licenses for AIX 5L V5.3 under the appropriate processor group.

    If additional processors are added after the initial system purchase and the intent is to run AIX 5L V5.3 or if AIX 5L is added to another active processor not previously running AIX 5L V5.3, additional licenses for AIX 5L V5.3 and SWMA for AIX for those processors must be acquired. Also, when adding additional processors, the AIX SWMA contract term (1 or 3 years) associated with the processor additions must be the same as selected for AIX 5L with the initial system purchase. This rule applies to other license programs offering SWMA as well.

  • AIX 5L V5.2 and V5.3 on POWER5 systems

    License entitlement for AIX 5L V5.2 or V5.3 on POWER5 systems is based on the total number of active processors running AIX Operating System. For example, for a machine/type 9117-570 ordered with a four-way processor configuration on which the end user intends to run AIX 5L V5.2 or V5.3 on two of the four active processors customers should order two licenses under the appropriate processor group.

  • AIX 5L V5.2 and V5.3 on POWER4 systems

    License entitlement for AIX 5L V5.2 or V5.3 on POWER4 systems is based on the maximum number of processors within a system (SP Systems included) 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

  • SWMA

    For each AIX 5L V5.2 (5765-E62) or V5.3(5765-G03) license ordered, an order for either the one-year (5771-SWM) or three-year (5773-SM3 or 5773-SWM) SWMA for AIX Operating Systems must also be submitted. Pricing for SWMA for AIX Operating Systems is based on processor group classification with price times quantity ordered. The quantity of processors associated with SWMA for AIX Operating Systems must be equal to the quantity of AIX licenses specified.

  • Unbundled AIX on POWER5

    AIX 5L willl be unbundled and separately priced for new POWER5 processor-based systems. For POWER4 processor-based systems, AIX 5L will continue to be included with the system purchase price.

  • License transfer

    The AIX 5L V5.3 license will be transferable to comparable processor systems ONLY within a customer's enterprise.

    The AIX 5L V5.2 license will be transferable to comparable processor systems within a customer's enterprise and will also be transferable with the hardware outside the customer's enterprise.

 for AIX 5L V5.2 (this
 option is only available
 when AIX 5L V5.2 is
 requested preinstalled.)

The preinstall option is available at no additional charge.

Single pallet delivery: Single pallet delivery consolidates pSeries hardware, AIX 5L V5 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.

LPAR machines

Software ordering instructions for multiple AIX operating systems for LPAR machines

Since the availability of AIX 5L V5.2, IBM offers multiple operating system releases that support logical partitioning of LPAR-capable hardware. With this initial offering you can order any combination of operating system releases for the same machine, but only one of the operating systems can be preinstalled (preinstall is not an option for eServer i5). On POWER4 based machines when the machine is preinstalled by manufacturing, it continues to be preinstalled in SMP mode, requiring customers who run logical partitions to reinstall. POWER5 based machines will be preinstalled as a single partition that contains all the hardware. The customer may be able to add partitions and reassign hardware to the new partitions without reinstalling.

Order structure

For LPAR-capable machines to be used in the LPAR-mode, you can order any AIX 5L V5.1, V5.2, and V5.3 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. Additional AIX 5L SPO (5692-A5L) orders are required to take delivery of any other AIX release being requested. Media charges apply to each SPO order if media is requested. To order multiple releases of AIX for LPAR installation, you must also select either the one-year (5771-SWM) or three-year (5773-SM3 or 5773-SWM) Software Maintenance for AIX Operating Systems offering.

Note: AIX 5L V5.1 is not valid with POWER5 processor-based machines.

For LPAR preinstalled systems built in Rochester for U.S. delivery, feature 3483 must be included on the SPO (5692-A5L) orders that are not being preinstalled to take advantage of single pallet delivery if media and publications are requested. These additional SPO (5692-A5L) orders must have the same system type/system number and scheduled shipment date as the hardware machine it is being ordered with to enable single-pallet delivery.

Products Currently Supported on AIX 5L V5.3

Licensed program products currently supported on AIX 5L V5.2 that are not offered during order creation using ECFGPWR when AIX 5L V5.3 is selected for the AIX operating environment, may not currently be supported on AIX 5L V5.3.

The following licensed program products or features have declared that they will run on AIX 5L V5.3. Additional products will announce support at a later date. These programs or features are orderable under the AIX 5L SPO 5692-A5L, using the appropriate feature number.

Sub-capacity pricing terms and conditions

To be eligible for Sub-Capacity Pricing, the machine on which the eligible products are installed and running must be eligible for Sub-Capacity pricing terms and conditions. Software pricing at less than full machine capacity for eligible products apply when running

  • AIX 5L V5.1, or later, on an IBM eServer pSeries 690 or equivalent partition capable operating system and machine
  • OS/400® V5.1, or later, running on an iSeries server

    Note: i5/OS V5R3 is required on the eServer i5.

  • Linux running in an LPAR under AIX 5L V5.1, OS/400 V5.1, or in a partition on an equivalent partition capable operating system and Server

Sub-Capacity Pricing for eligible products is based on the current Program pricing methodology but the number of processors will be determined based on the sum of processors for all partitions where the Program is defined(used). To obtain pricing at less than full machine capacity for eligible products, you are required to:

  • Install and use, when available, IBM's license use management program which installs with eligible IBM Programs.
  • Install available updates to the operating system and eligible products such that license use can be accurately managed.
  • If the use of Sub-Capacity Pricing terms results in a reduced requirement for entitlements, you can reallocate the entitlement difference by distributing entitlements across a larger or different set of systems, or reserve then for future growth. There will be no refunds for these "freed up" entitlements. Subscription, Software Maintenance and Support volumes and entitlements for existing contracts will continue at the same levels as the acquired licenses.

Variable charges: The applicable processor-based one-time charge will be based on the group of the designated machine on which the program is licensed for use. If the program is designated to a processor in a group for which no charge is listed, the charge of the next higher group listed applies. For movement to a machine in a higher group, an upgrade charge equal to the difference in the then-current charges between the two groups will apply. For movement to a machine in a lower group, there will be no adjustment or refund of charges paid.
