    * PROBLEM DESCRIPTION: SQA shortages due to suspended SRBs     *
    *                      that are scheduled for DISCARDDATA      *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When large number of SRBs are scheduled to issue
    IARV64 DISCARDDATA, SQA shortages can result due to
    suspended SRBs because of the LOCAL lock
    contention.
    

Problem conclusion

  • IARV64 DISCARDDATA code is changed so that it
    will not obtain the LOCAL LOCK when processing
    the request.
