APAR status

  • Closed as program error.

Error description

  • If WebSphere Application Server is configured with multiple
    servants (minimum servants greater than 1), this is also the
    number of servants that is started in recovery mode.  It is
    unnecessary to have more than 1 servant region during recovery
    mode restart.
    This (depending on minSRs setting) could greatly increase the
    amount of CPU time and elapsed time required to start the
    server in recovery mode, clean up the resources and shutdown.
    
    This apar will provide a fix to start only 1 servant regardless
    of specified min/max value when server is restarted in recovery
    mode.

    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V7.0, V8.0, and V8.5                 *

    * PROBLEM DESCRIPTION: WebSphere Application Server for        *
    *                      z/OS when started in recovery mode      *
    *                      honors the wlm_minimumSRCount           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A server started in recovery mode will start the mininum number
    of configured Servants (based on wlm_minimumSRCount).  This
    will cause unnessary consumption of CPU and delays in recycling
    the server.  The additional Servants are not needed to perform
    the recovery actions.
    

Problem conclusion

  • Code was modified to not honor the setting of
    wlm_minimumSRCount if the server is started in recovery
    mode.
    
    APAR PM74563 is currently targeted for inclusion in Fix Packs
    7.0.0.29, 8.0.0.6, and 8.5.0.2 of WebSphere Application Server.
