Error description

  • ABEND04E RC00C200C9 DSNB1OFA after changing zparm STATFDBKSCOPE
    from 'NONE' to 'ALL'.  An internal halfword counter overflowed
    causing a large overlay.  An internal DB2 PBG control block was
    overlayed resulting in subsystem termination.  Changing
    STATFDBK_SCOPE back to 'NONE' circumvents the error.
    ADDITIONAL SYMPTOMS:  ABEND0C4 DSNICMT2 RC00D93001
                          ABEND0C4 DSNB1PCK
                          ABEND04E RC00C200D8

    ****************************************************************
    When the user was collecting statistics
    recommendations into the SYSIBM.SYSSTATFEEDBACK
    catalog table by using the STATFDBK_SCOPE
    subsystem parameter, an ABEND0C4 RC00000038
    in DSNICMT2 OFFSET00202 occurred.
    The abend occurred due to a storage overflow in one of
    the variables used to calculate the required storage size
    for storing the distribution statistics. This problem occurs
    when the Db2 catalog has many frequency statistics some of
    which may be outdated.
    Additional symptoms:
    ABEND04E RC00C200C9 DSNB1OFA + x'01454'
    Additional keywords:
    DB2OVRLAY/K
    

Problem conclusion

  • Code was modified to prevent the storage overflow.
