Error description

  • Workload Manager (WLM) on 9.7 fix Pack 2 does not work properly.
    It fails to change the priority of db2 agent threads.  Note
    that this problem exists on Linux platform only.  All other
    platforms work correctly.  Also, note that this problem exists
    in fix Pack 2 only.  All other fix packs of 9.7 do not have this
    problem.  All other releases don't have it, either.
    
    Changing the priority of an agent gets changed at DB2 level. We
    can confirm it with "db2pd -agents" output.  However, it is not
    reflcted at Operating System Level. "ps-lLfp <PID of db2sysc>"
    does not show the change.  After applying the APAR fix, both
    "db2pd -agents" and "ps -lLfp" show the change and WLM will
    behave properly.
    
    Everyone using WLM on Linux platform must apply the fix
