IBM Maximo Asset Management, Version 7.6

Verifying large page size support for AIX

For Maximo® Asset Management to function correctly, large page size support must be enabled on AIX® servers that host WebSphere® Application Server.

About this task

If you are deploying Maximo Asset Management on WebSphere Application Server hosted on an AIX system, that system must be configured to support large page sizes. 

Large page usage is primarily intended to provide performance improvements to high performance computing applications. Typically this feature is enabled by default on AIX systems.

Procedure

  1. Log on to the AIX system that hosts WebSphere Application Server and open a console window. You must have root authority to work with the AIX operating system commands.
  2. Verify large page size support by running the following command:
    ps -Z
    Output from the command includes 4 K and 64 K page sizes that are listed for processes, for example:
    # ps -Z
        PID    TTY  TIME DPGSZ SPGSZ TPGSZ CMD
     311342  pts/4  0:00    4K    4K    4K ksh
     397526  pts/4  0:00    4K    4K    4K ps
     487558  pts/4  0:00   64K   64K    4K sleep
