Problem summary

  • ****************************************************************

    * RECOMMENDATION:                                              *
    ****************************************************************
    ABEND04E RC00C90101 DSNKPGCM ERQUAL5008 occurred when customer
    reverted from DB2 for z/OS Version 9 new function mode (NFM) to
    DB2 for z/OS Version 9 compatibility mode* (CM*) and index
    compression was active (COMPRESS YES).
    
    While in CM*, an index leaf page split did not allocate the
    required compression extension area. This caused the abend and
    pages were added to the Logical Page List (LPL).
    
    If this abend occurs, customer may:
    1. Recreate the index in CM* and no longer use index
       compression.
    2. Migrate to NFM and REBUILD the affected indexes.
    

Problem conclusion

  • Code has been modified to make sure index pages are allocated
    with the compression extension area when index compression has
    been activated, regardless if customer reverts back to
    compatibility mode* (CM*).
