Operating System Requirements
This chapter provides operation system requirements for installing an Ex Libris application on the AIX operating system.
Operating System
The following AIX operating systems are supported:
- AIX 5L version 5.3, TL 05, Service Pack 06 or later
- AIX 6L version 6.1, TL 02, Service Pack 05 ("6100-02-05") or later
AIX 5.3 is supported for the following Ex Libris products:
- Aleph 18.01
- Aleph 19.01
- Aleph 20.x
AIX 6.1 is supported for Aleph 20.x.
The file system should be configured and mounted without the CIO (concurrent IO) option.
Operating System Patch
Maintenance level 5 or higher is required.
The following are required packages for AIX 5 and AIX 6:
- bos.adt.base
- bos.adt.lib
- bos.adt.libm
- bos.perf.libperfstat
- bos.perf.perfstat
- bos.perf.proctools
- xlC.aix50.rte:8.0.0.3 or later (AIX 5.3)
- xlC.rte:8.0.0.0 or later (AIX 5.3)
- xlC.aix61.rte:9.0.0.1 or later (AIX 6.1)
- xlC.rte:9.0.0.1 or later (AIX 6.1)
- rsct.basic.rte (For RAC configurations only)
- rsct.compat.clients.rte (For RAC configurations only)
- xlC.aix61.rte 10.1.0.0 or later
The following are the 5.3 ML5 required patches:
- IY84780
- IY68989
- IY89080
- IY92037
- IY94343
- IZ01060 or efix for IZ01060
- IZ03260 or efix for IZ03260 (IZ03260 for ML6, IZ03475 for ML7) to address ORA-27061
Use the latest patch from IBM. IBM provides patch information at:
The following patches are required for AIX 6L:
- IZ41855
- IZ51456
- IZ52319
It is likely that the above three APARs have already been built into the later OS version if the OS is later than the listed version (AIX 6.1 TL 02 SP5) and therefore, can be safely ignored. It is found that if the OS level is higher than 6100-02, you can skip installing IZ51456. If the OS level is equal to or higher than 6100-04-07-1036, the fix for IZ41855 is superseded by IZ39665 and the fix for IZ52319 is superseded by IZ55160.
Note that all AIX maintenance packages and patches are available from the following Web site. Download the packages that matches your AIX version and technical level.

AIX Kernel Settings: AIXTHREAD_SCOPE=S
In addition, for Aleph installation, the following RPMs should be installed from aixtoolbox:
gcc-3.3.2gcc-c++-3.3.2libgcc-3.3.2libstdc++-3.3.2libstdc++-devel-3.3.2
Windows Manager
The installation of the Oracle server in silent or online install modes requires X Windows. Use any Windows manager that supports Motif.
Native C Compiler
Requires XL C/C++ 9.0 or later. It is also necessary to install the native C++ compiler.
Required Executables
The following executable files must be present in the /usr/bin directory:
bash, tcsh, make, ar, ld, nm, ksh
System Environment Setup
The system must set the following shell limits to the recommended values for the oracle user or any users who use Oracle services.
|
Soft CPU time [-1] Soft FILE size [-1] Soft DATA segment [-1] Soft STACK size [-1] Soft RSS size [65536] Soft NOFILE descriptors [2000] Processes (per user) [-1] |
- As the root user, use smit chuser to update the shell limits for the oracle user and other users.
The system must set the following kernel parameters greater than or equal to the recommended values.
|
maxuprocs >= 2048 ncargs >= 128 |
- As the root user, use smit chgsys to verify that the value of Maximum number of PROCESSES allowed per user is greater than or equal to 2048 and that the value of ARG/ENV list size in 4K byte blocks is greater than or equal to 128.
- Verify the asynchronous input/output processes.
- Confirm that aio_maxreq is 64K (65536) with the following command:
|
ioo -o aio_maxreqs |
