  • Closed as program error.

Error description

  • Over a period of time and under certain circumstances
    (server being down unexpectedly or cleanup not being
    performed) job capacity can be lost.
    
    When this occurs, jobs will remain in submitted state
    and the part.0 joblog will mention no capacity, without
    any jobs running (or not enough jobs running to account
    for no capacity)

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of WebSphere Compute Grid V8          *
    ****************************************************************
    * PROBLEM DESCRIPTION: The Job Scheduler can not dispatch jobs *
    *                      due to full capacity.                   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The Job Scheduler may not keep track of ended jobs and update
    its
    internal capacity counters.  This can cause job dispatches to
    fail
    due to full capacity.
    

Problem conclusion

  • A code update has been made to allow the Job Scheduler to
    detect and reclaim job class capacity.  The frequency with
    which this detection occurs is configurable with scheduler
    custom property: MaxJobCapacityLeakDetectionFrequencyMinutes.
    To enable just the job class capacity detection, enable
    scheduler custom property: EnableJobCapacityLeakDetection.  To
    enable job class capacity detection and recovery, enable
    scheduler custom property:
    EnableJobCapacityLeakDetectionAndRecovery.
    The fix for this APAR is currently targeted for fixpack 8.0.0.3.
