Error description

  • ABEND0C4 RC11 DSNRLLM1.DSNRPBCW+045A may occur on an accelerator
    enabled system after STOP ACCEL command is issued at least once.
                                                          (d182801)
    

Local fix

  • Users of an accelerator with DB2 table
    SYSACCEL.SYSACCELERATORS altered to have the new column
    ACCELERATORSRL added can temporarily bypass the problem
    by removing the bad PTF UI34442 (PI49422) until the
    fixing PTF or aparfix from PI61661 can be applied.
    The added column can be left intact.

    ****************************************************************
    ABEND0C4 RC11 DSNRLLM1.DSNRPBCW+045A may occur on an accelerator
    enabled system after STOP ACCEL command is issued at least once
    and DB2 table SYSACCEL.SYSACCELERATORS has already been altered
    to add ACCELERATORSRL. It is because the DB2 internal record for
    the update of ACCELERATORSRL is not cleaned up properly and in
    rare cases, it could result in DB2 abend or even system crash.
    It can happen especially when frequent storage contraction
    occurs which can cause the storage to becaome unavailable
    leading to the abend.
    

Problem conclusion

  • DB2 is modified to process the URE record for the update of
    ACCELERATORSRL correctly.
