Additional Product Information
Scalability and Capacity
In addition to providing a 32-bit kernel, AIX® 5.1 offers a scalable, 64-bit kernel capable of supporting increased system resources and much larger application workloads on 64-bit hardware. The 64-bit kernel offers scalable kernel extension interfaces, allowing kernel extensions and device drivers to make full use of the kernel's system resources and capabilities.
The expanded capabilities of the 64-bit kernel improve the ability to run an expanding application workload on a single system. This ability is important for a number of reasons.
Server consolidation and workload scalability will continue to require higher capacity hardware systems that support more memory and additional I/O devices. The 64-bit kernel is designed to support these requirements for years to come.
Kernel extensions and device drivers must be compiled in 64-bit mode to be loaded into the 64-bit kernel. The 64-bit kernel, combined with header files and libraries, provides the environment for porting and developing kernel extensions.
64-bit Application Scalability
AIX 5.1 provides a scalable ABI for 64-bit applications. This scalability:
The scalable 64-bit ABI is supported by the 32-bit kernel and the 64-bit kernel.
For example, the 64-bit kernel is designed to support file sizes larger than 1 terabyte. By using the scalable 64-bit ABI, 64-bit applications will be able to use existing interfaces to process these large files. To take advantage of the scalability improvements to 64-bit programs, all 64-bit programs and libraries must be recompiled for AIX 5.1. In addition, existing 32-bit kernel extensions and device drivers used by 64-bit applications may have to be modified in order to support the new 64-bit ABI.
Workload Manager Enhancements
Workload Manager is enhanced to:
Additional capabilities which, Workload Manager offers are:
These capabilities can be easily managed through Web-based System Manager, SMIT, shell scripts, or command line interfaces. Monitoring is available using the new wlmmon and wlmperf tools.
Very Large Program Support
AIX 5.1 offers new flexibility for 32-bit "maxdata" programs by allowing the segments of the data heap (up to eight 256 MB segments) to be created dynamically.
The large program support previously available did not allow data heap segments to be used for any other purpose, even if the data heap never grew large enough to use all the reserved segments.
The Very Large Program Support will allow the data heap segments to be created dynamically. Until a segment is needed for the data heap, it may be used by shmat and mmap.
In addition, when Very Large Program Support is enabled for an application, segments allocated by shmat and mmap are allocated in descending order instead of ascending order.
Very Large File Support
Cachefs is enhanced to work under the 64-bit kernel and will support large file systems. It will handle files larger than 2 GB, although the cache file does not have to be larger than 2 GB. As a result, data can be accessed faster.
JFS2 is a new file system providing the capability to store much larger files than the existing Journaled File System (JFS). It is the default file system for the 64-bit kernel.
Customers have the choice of implementing JFS or taking advantage of the additional 64-bit functionality of JFS2. The following table provides a summary of the differences between JFS2 and JFS.

Network Technology and Performance
IP Multi-path Routing and Multiple Gateways with Dead Gateway Detection
Multi-path routing is added to provide users the ability to specify multiple routes to a destination.
Web Serving Enhancements and Dynamic Content and Web Cache Enhancements
A set of APIs provided by Fast Response Cache Architecture (FRCA) enables e-business applications to cache data such as Web content in the Network Buffer Cache (NBC).
Through these APIs, Web serving can be done in the kernel via FRCA and NBC, significantly reducing the path length and increasing the performance of e-business applications for net commerce. FRCA and NBC are enhanced from managing static data to managing dynamically generated data.
FRCA will support the Hypertext Transport Protocol (HTTP) Version 1.1, a standard of IETF RFC, including the persistent connection aspect of that protocol.
Dynamic Feedback Protocol (DFP) Support for Load Balancing
DFP is a way to provide load statistics to a load manager (Cisco LocalDirector) so that load elements can be balanced by sending subsequent connections to servers that are more available.
DFP helps improve server response in a Multi-node Load Balanced (MNLB) environment.
TCP Explicit Congestion Notification (ECN)
Enhancements were made to improve performance of TCP/IP over congested networks, especially, for Web serving. All of the following features are configurable:
TCP splicing helps push the data-relaying function of a proxy application (from server side socket to the client side socket or vice versa) into the kernel. Performance of proxy applications is improved by reducing the pathway length through which data must travel.
Software products that are expected to take advantage of this function include Network Dispatcher and, potentially, the Web Traffic Express caching proxy server.
Virtual IP Address (VIPA)
This capability allows system administrator to define a virtual IP address for a host and, from a TCP connection standpoint, decouple the IP address associated with physical interfaces. As a result, user connections should not be affected if some interfaces are lost.
Network Interface Takeover
This new feature allows the configuration of multiple adapters, including IBM 10/100 Mbps Ethernet PCI adapter, Gigabit Ethernet-SX PCI adapter, and 10/100/1000 Base-T Ethernet PCI adapters and allows one or more to be designated as a backup. If any hardware failure (adapter or cable) occurs, the next alternate adapter immediately takes over. This gives has the appearance of "one network interface" to the user and continues to keep network traffic moving with minimal delay.
Network interface takeover is an additional option to EtherChannel, Cisco Systems Network Bandwidth Aggregation, and Load Balancing technology, which:
Sendmail Version 8.11
This new version of sendmail improves performance by having:
Some of the other features include:
This functionality helps enhance the robustness and ease-of-use in gathering network traffic data to improve problem determination for network applications.
The Packet Capture Library, libpcap, provides:
Quality of Service (QoS)
This function is enhanced to allow system administrators the ability to manage polices for the QoS Manager from the command line.
This is important when two or more overlapping policies are installed, policies can then be enforced in order of highest priority.
AIX Multiple-protocol Over ATM (MPOA) Token Ring Support
Token Ring emulation support for (MPOA) provides improved management and performance of an ATM LAN emulation network by combining multiple-edge routers into a single router image.
This support provides better interoperability between an ATM network utilizing AIX MPOA support and token-ring networks.
MPOA IP Fragmentation
MPOA IP packet fragmentation support provides for instances where there is a heterogeneous network environment with varying Multiple Transmit Units (MTUs).
This capability extends to circumstances where there are network configurations and normal MTU path discovery is not available.
ATM LANE/MPOA RAS Enhancements
The following enhancements to the ATM LANE and MPOA statistics and trace tools gain improved serviceability of installed products.
Virtual LAN (VLAN)
Gigabit EtherChannel Support
The Cisco System Network Bandwidth Aggregation and Load Balancing technology, called EtherChannel, builds upon standard and 802.3 Fast Ethernet to provide the functionality to aggregate a bandwidth of multiple Ethernet interfaces.
AIX 5.1 adds Gigabit EtherChannel support, allowing the aggregation of up to four Gigabit Ethernet ports and an increase of bandwidth capabilities.
System Networking, Analysis, and Performance Pilot (SNAPP)
SNAPP provides a hand-held Personal Digital Assistant (PDA) menu-driven interface for performing AIX administration tasks.
The primary purpose of SNAPP is to allow minimum IP address configuration on a newly preinstalled system that does not have a monitor or ASCII terminal and keyboard connected to it.
Once the AIX system is on the network, remote access can then be used to further configure the system. Users can add new, customized functionality to the SNAPP interface with minimal programming.
The SNAPP application consists of a server and a client.
The client portion may be obtained from the /usr/samples/snapp directory on an AIX system or it may be downloaded from the AlphaWorks Web site:
Reliability, Availability, and Serviceability (RAS)
Recover from System Hangs
This shdaemon command function aids system administrators by providing a SMIT-configurable mechanism to detect system hangs and initiate the configured action. When a system hang occurs, one of the following actions can take place:
System administrators can set up these actions with appropriate priority and turn them on or off as needed.
An additional benefit of the tool is that it can be set with a threshold low enough that when that level occurs, a log entry is generated. The frequency of log entries can provide a measure of saturation and resource utilization.
Error Log Scalability Enhancements and Error Thresholding/Activity Counters
Enhancements are made to the error log to detect consecutive duplicate errors and help prevent the error log from being overloaded.
These enhancements provide a mechanism to keep track of the number of times an exactly identical error at the bit level occurs within a limited time period. An entry will be added to the error log along with the number of occurrences for this error.
Examples of this type of error include:
This function is automatically enabled.
Automatic Dump Analysis
This tool enables accelerated customer support with less customer interaction time. The Automatic Dump Analysis tool is capable of automatically examining a dump and pulling out (in text) relevant information for forwarding to support entities as an e-mail attachment. This will allow early diagnosis of dumps without having to send the entire dump file.
Error Log Retrieval API for Diagnostics
As part of the error log analysis performed by diagnostics, the errpt command with the -g flag is invoked to get raw data for each error log entry. This data is parsed and then put into a data structure for use by the calling application.
AIX 5.1 provides the calling application an API to get data directly from the error log. This new method for obtaining data from applications is much faster when compared to the errpt raw mode.
With this enhancement, error reports will contain both the error report and the diagnostics analysis. Previously, the error report only showed the error. A separate command was required to see the diagnostic analysis.
With this change the error report will include diagnostic analysis for errors that have been processed. This may include such errors as:
Diagnostic analysis will give an indication of whether the hardware needs replacing or if the error may be safely ignored.
Dump Reliability Improvements
System dump capability has been improved to increase reliability.
These improvements will help ensure that system dumps are consistent and reliable for easy problem determination.
As dumps approach 3 GB in an uncompressed state, situations arise where dumps are incomplete or unavailable to technical support resources. This improvement adds compression as soon as possible, and adds a cron job to estimate dump size and send an error message recommending a larger dump device when it is appropriate.
Because paging space is the default dump device, this enhancement helps avoid the problem of insufficient paging space for dumps. The "snap" command is modified to eliminate an additional copy of the dump when it gathers files for its image. This reduces the space required to take a snap image.
In addition, a new command, snapcore, is available to assist in the problem determination of core dumps. This command can be used to automatically package not only a core dump but also executable files and shared libraries, and send the complete package to technical support personnel.
Generate Core Files Without Requiring Process Termination
AIX 5.1 provides a capability to generate a core file for an application without requiring application termination. This capability helps increase the application availability as well as serviceability.
Allowing the dd Command to Span Volumes
The dd command has been enhanced to allow the ability of writing data to multiple tapes. This new feature prompts users to insert another tape when the tape currently in the tape drive reaches its end.
AIX 5.1 makes available an additional ANSI terminal. This addition helps ease the work of system administrators.
Enhancements to Cron Job Logging
The cron command has been enhanced to provide a more detailed log file, including logging tasks and processes with the crontab to launch them. The cron command can even log the completion time and exit status information.
New Coredump Naming
The coredump naming convention has been changed to keep as many coredumps saved as systems allow. The coredumps will be named "core.pid.time", where "pid" is the process id of the dump process, and "time" is a timestamp in the form of "ddhhmmss."
Kernel Debugger (KDB) Enhancements
KDB improvements include the following options:
AIX System and Networking Security
Enhancements to Increase Affinity with Linux
In conjunction with the AIX Toolbox for Linux Applications packaged on separate media, new APIs are added to AIX so that Linux applications using these routines do not have to supply their own libraries.
The goal is to have "compile and go" operability for Linux applications. This does not extend to the kernel and device driver layers.
AIX Toolbox for Linux Applications
The AIX Toolbox for Linux Applications provides the ability to build and execute applications commonly found in Linux distributions. It supports a wide variety of software, including:
Featured software includes:
Base Operating System
NFS Statd Multithreading
The status monitor provides a general framework for collecting network status information. Implemented as a daemon that runs on all NFS configured machines, the status monitor provides a simple protocol that allows applications to easily monitor the status of other machines.
Deactivating Active Paging Spaces
This function provides new flexibility without rebooting after:
Until this release, allocated and activated paging space had to remain active until the next reboot. With this release, paging space can be deactivated without rebooting by using the new "swapoff" command. A new "shrinkps" command:
The use of a shell script reduces the possibility of an unbootable state because users will not be allowed to run out of adequate paging space. The script checks paging space actually in use and adds a buffer for paging space warning threshold.
AIX 5.1 provides an optional buckets-based extension of the default memory allocator (the malloc subsystem) that improves performance for applications that issue large numbers of small allocation requests.
Each bucket consists of a block of memory that is subdivided into a predetermined number of smaller allocatable blocks of uniform size. Organizing allocatable memory in this fashion often provides faster access for allocation requests falling within the range of sizes defined by the buckets.
When this capability is enabled, allocation requests that fall within a predefined range of block sizes are processed by Malloc Buckets. All other requests (for example, those outside the defined range of sizes) are processed in the usual manner by the default allocator. Up to 128 buckets are available per heap (refer to the Malloc Multiheap documentation for details on this capability).
Number of buckets, bucket sizing factor, and other configuration values are specified via an environment variable prior to process startup. More information on configuring the MALLOCTYPE and MALLOCBUCKETS environment variables is available in the book "General Programming Concepts: Writing and Debugging Programs."
SVR4 Printing Subsystem
AIX 5.1 provides the UNIX® System V style file spooling subsystem and makes it available as an administrator configurable option. Enabling this option allows users who are more comfortable with System V printer utilities to more easily use AIX 5.1.
System V Packaging Commands
System V Packaging Commands are available for customers to create and install a package in the System V packaging format. These commands are:
AutoFS is enhanced to support the multithreaded automountd daemon. This allows automountd to provide more jobs than before.
In addition to fulfilling mount requests, the new automountd handles requests such as:
It is 64-bit enabled, which permits it to be run in either 32-bit or 64-bit kernel.
The /proc Filesystem
The /proc file system provides access to the state of each process and thread in the system.
The file system is mounted over /proc. Standard system call interfaces, such as open(), read(), write(), lseek(), are used to access /proc files. Programs such a debuggers can use /proc to control a process being debugged. /proc provides the ability to:
Increased Concurrent Group per Process Limit
The number of concurrent groups per process has been increased from 32 to 64. The concurrent group set is used to control access to files and programs. Increasing this value allows users greater flexibility in classifying and protecting system resources.
Administrators who require access to resources belonging to a large number of groups will be able to access those resources without having to change their concurrent group set.
Increased Argument List Limit
The argument list limit has been increased to 512 K from 24 K (24 K is the traditional AIX limit and system default).
Applications can specify the length of command line argument and the
length of the environment (stream length) list in bytes. Users will be
able to use the default or automatically specify an upper limit (512 K)
for their application.
DMAPI Data Management API
AIX 5.1 includes the implementation of the DMAPI, as defined in the XDSM API specification.
DMAPI is a technology, which enables the development of relatively portable data management applications, such as hierarchical storage management (HSM), by providing the underlying JFS support and programming interface for those applications. DMAPI is available on the 32-bit kernel only.
LVM Scalability Variable Logical Track Group (LTG)
The LVM now has a constant max transfer size of 128 K, (which is known within LVM as the LTG). Enhancements are provided to allow a Volume Group (VG) LTG size to be specified at VG creation time and to change the LTG size of an existing volume group.
Different LTG sizes of 128 K, 256 K, 512 K, and 1024 K are now supported and verification for the sizes of 512 K and 1024 K are underway. The different LTG sizes pend on the max transfer size of the member disks of the volume group.
LVM Mirror Write Consistency
MWC helps ensure data integrity on logical volumes in the event of a system crash during mirrored writes.
The existing method achieves this by logging when a write operation occurs. The LVM makes an update to a log (MWC log) that identifies what areas of the disk are being updated prior to performing the write of the data. This results in a performance degradation during random writes.
There are now two ways of handling MWC: Active and Passive. The existing method is Active MWC and the new MWC is called "Passive."
The Active MWC method (existing MWC) is still supported and is the default mode when a mirrored logical volume is created.
Passive MWC reduces the instance of having to update the MWC log on the disk. This method logs that the logical volume has been opened but does not log the writes. If the volume group is not deactivated before reboot (crash), then the LVM starts a forced synchronization of the entire logical volume when the system restarts. Data consistency exists for reads that occur during the synchronization so that applications can start using data as soon as the volume group is varied on.
The new Passive MWC method is intended to provide better random write performance on mirrored logical volumes when compared to the Active MWC method.
Hot Spare Disk Support in Volume Group
The LVM previously shipped with AIX took no action when partitions went stale or disks went missing other than logging an error in the error log.
The new ability of LVM to optionally provide hot spare disks within a volume group and automatically synchronize stale partitions helps to increase the availability of mirrored data.
In addition, the Logical Volume Manager will attempt to reactivate a missing disk. If the disk cannot be restarted, then its mirror copy will be migrated to a hot spare disk if such disk with proper size exists.
Hot Spot Management in Logical Volume Group
LVM provides the ability to move physical partitions (smallest possible data unit in a volume group) to any member disk of the volume group. Sometimes it is necessary to migrate partitions to new disk for maintenance (for example, disk replacement). This migration may also achieve a performance gain for I/O if there happened to be high-traffic partitions all located on a single disk and some were migrated to other member disks.
Currently, there are no tools at LVM level that will identify the
partitions by the number of I/O structures. There are tools that provide
similar information like iostat and filemon, but they do not directly
identify the partitions at the LVM level. Hot spot management provides
two commands one that will identify the hot spots and another that
migrates the hot spot to a different location.

Programs compiled to exploit POWER2 or POWER3 technology must be run on the same processor type. 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.
64-bit applications produced using AIX Version 4 will not execute on AIX Version 5. These applications will need to be recompiled from the source on AIX Version 5 to execute on this version of AIX. 64-bit applications produced using AIX Version 5 on any of the 32-bit or 64-bit processor models will execute without recompilation on the 64-bit processor models. 32-bit applications produced using AIX Version 5 on either 32-bit or 64-bit processor models will execute without recompilation on both models.
X11R5/X11R6 Compatibility Issues On AIX Version 5: The AIX Version 5 X-server uses the X-Consortium release 6 of X (commonly known as X11R6). The libraries shipped by IBM with XllR6 are backward compatible and the client applications which access these libraries work as on AIX Version 4. As on AIX Version 4, IBM will also ship X11R3, X11R4, X11R5 compatibility installation options for maximum customer flexibility.
The broad majority of applications using X fall into this category and will not see any difficulty. However, a small minority 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, a customer may have an extension which will not work with X11R6, for example, a customer:
In these cases, the extension will need to be made compatible with X11R6 before they will execute properly. Customer-developed extensions and sample X-consortium extensions will need to be recompiled with the X11R6 environment. For third-party extensions, the customer should contact the vendor for a X11R6 compatible update.
Customers using non-IBM display adapters 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. The customer should contact the particular vendor of the display adapter for this software.
IBM plans to provide a porting guide with AIX Version 5 to assist customers and vendors developing adapters or extensions for AIX.
Between AIX Versions 3 and 5: All AIX applications using AIX Version 3 Release 3.2 or greater, for POWER-, POWER2-, and PowerPC-based models, that are written in accordance with the guidelines in this announcement and other AIX announcements will run on AIX Version 5 without recompilation for those same models. The exceptions to this statement would be applications compiled using POWER2 or PowerPC specific compiler options but run on models other than POWER2 or PowerPC or applications using:
Applications created on a system using AIX Version 5 may not
function properly on a system using AIX Version 3. Applications
must have been created using the AIX shared libraries for these binary
compatibility statements to apply.
