Error description

  • During a QUIESCE utility with more than 50,000 objects, IRLM
    abended with  ABENDU2022 MODULE DXRRL010 OFFSET0FFA.  This abend
    was due to XES ABEND071 RC00000030
    
    There was a false 'spin' detected due to a high volume of DB2
    Utility locks with zeros for hash value.
    

Local fix

  • reduce number of objects for a single utility
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 10 for z/OS users of utilities.      *
    ****************************************************************
    * PROBLEM DESCRIPTION: ABENDU2022 at DXRRL010 OFFSET0FFA and   *
    *                      ABENDS0071 RC00000030 at IXLR1GLC       *
    *                      during a QUIESCE utility running on a   *
    *                      large object list defined by a LISTDEF, *
    *                      resulting in ABEND04E RC00E40020.       *
    ****************************************************************
    * RECOMMENDATION: Apply corrective PTF when available.         *
    ****************************************************************
    A QUIESCE ran on a large object list defined by a LISTDEF which
    contained more than 10000 table spaces.  ABENDU2022 at DXRRL010
    + x'0FFA' and ABEND0071 RC00000030 at IXLR1GLC occurred during
    the serialization processing of the QUIESCE utility, resulting
    in ABEND04E RC00E40020.
    This problem occurred because a lock used for utility
    serialization was requested without a hash value, causing IRLM
    to scan a large resource list and cause the abends.
    This problem could also occur for any DB2 z/OS utility operating
    on a large list of objects.
    
    Additional Symptom:
    ABENDS0071 RC00000038/RC00000010
    ABEND026   RC0C3E0101
    

Problem conclusion

  • PM83559 is a pre-conditioning APAR that includes changes to
    support the fix for the reported problem, which will be enabled
    via another APAR at a later date.  Changes in PM83559 should be
    generally transparent to users.  In a data sharing group, the
    fix for this pre-conditioning APAR must be applied to all
    members before the later enabling APAR, when available, is
    applied to any member.  The fix for the reported problem will
    not be effective until it is enabled by the follow-on APAR.
    
    Collectively, the APARs change utilities code to obtain the
    lock(s) used to serialize utilities with an appropriate hash
    value.
