Restarting the system logger address space

If it is necessary to restart the IXGLOGR address space to correct problems or apply maintenance, then the following procedure is recommended:
  1. Take action to cause any log stream connectors (exploiters) to disconnect from their log stream(s).
    You can use the following commands to identify any connectors and which log streams need attention.
    Display LOGGER,C,JOB=*
Display LOGGER,C,LSN=*

    When there are no log stream connections remaining on the system, IXG601I message output will indicate 'NO MATCHING INFORMATION FOUND.'

  2. Issue the command FORCE IXGLOGR,ARM and wait for it to complete (see message IXG067E in z/OS MVS System Messages, Vol 10 (IXC-IZP)).
  3. If this restart is to install maintenance, ensure it is applied at this point.
  4. Issue the command START IXGLOGRS to restart system logger.
  5. Take action to reconnect to log streams as needed.
Note: The FORCE IXGLOGR,ARM command will cause disconnects for active log stream connections on the system and log stream requests will fail until logger is restarted. Applications with log stream connections may experience outages when system logger is unavailable. Log streams will need to be reconnected when system logger is available to resume operations.

For more information on the START IXGLOGRS command, see IXGLOGRS - Start the IXGLOGR server address space. For more information on availability of the IXGLOGR address space, see z/OS MVS Setting Up a Sysplex.
