7.1.12 Setting to reduce memory usage by the job execution control manager (jpqman) when enumerating job information

When the job execution manager (jpqman) enumerates job information, memory usage is proportional to the number of listed items. With more items added, the following commands sometimes fail and message KAVU4280-E is output to the integrated trace log. If this happens, you might need to perform a setting to reduce the amount of memory used by the job execution control manager when enumerating job information.

The procedure for reducing memory usage by the job execution control manager when enumerating job information is as follows.

Organization of this subsection

(1) Setting procedure

  1. Stop JP1/AJS3.

    In Windows:

    From Administration Tools in the Windows Control Panel, choose Services and stop the following service:

    - JP1/AJS3 service

    In UNIX:

    Execute the following commands to stop the JP1/AJS3 processes and to check that all processes have stopped:

    # /etc/opt/jp1ajs2/jajs_stop#1

    # /opt/jp1ajs2/bin/jajs_spmd_status

    #1

    First check whether the JP1/AJS3 processes are set to stop automatically.

  2. Execute the following command to set the environment setting parameter described in (2) below.

    jajs_config -k definition-key-name "environment setting parameter-name"=definition-contents
  3. Restart JP1/AJS3.

    The setting takes effect.
