PM90579: JOBCLASS CAPACITY LEAK DETECTION AND RECOVERY

8.0.0.3: WebSphere Extended Deployment Compute Grid V8.0 Fix Pack 3
8.0.0.4: WebSphere Extended Deployment Compute Grid V8.0 Fix Pack 4
8.0.0.5: WebSphere Extended Deployment Compute Grid V8.0 Fix Pack 5

APAR status

• 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.
