Problem summary

    * USERS AFFECTED: All DB2 10 and DB2 11 for z/OS users of XML. *
    ****************************************************************
    * PROBLEM DESCRIPTION: This apar addresses a potential         *
    *                      accumulation of storage problem that    *
    *                      can occur when an XML error path is     *
    *                      taken.                                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Storage which is obtained on behalf of XML used for DOCID ANDing
    and ORing can accumulate if an error path is taken in regards to
    RIDs because it is never freed.  This problem can only occur
    during error path processing (for example, if a resource
    unavailable condition for RIDs is detected).  If this is the
    case, it is likely that the -904 would be issued because of a
    physical or logical RID overflow with a module name of DSNXRDOC
    or DSNXRDO9 with a reason code of rc00C900BC.
    

Problem conclusion

  • The code in DB2 is modified to free XML DOCID storage if a
    'resource unavailable' condition is detected.  This will prevent
    storage from accumulating for XML processing during an error
    path.
