Error description

  • A REORG of a mix of RRF and BRF parts when SPRMRRF is set to
    zero can result in storage overlays, and potentially bring DB2
    down.

Local fix

  • 1)  Turn on SPRMRRF (1) so that all parts will be converted to
        RRF by REORG.
    .
    2)  With SPRMRRF (0), avoid reorganizing partitions that have
        mixed row format in a single REORG.
    .
    

Problem summary

    * USERS AFFECTED: All DB2 9 for z/OS users of REORG            *
    *                 TABLESPACE utility.                          *
    ****************************************************************
    * PROBLEM DESCRIPTION: REORG TABLESPACE failed with ABEND0C4   *
    *                      RC38 in DSNIRLPG + x'2B08' on a         *
    *                      partitioned table space with SPRMRRF    *
    *                      set to DISABLE                          *
    ****************************************************************
    * RECOMMENDATION: Apply corrective PTF when available.         *
    ****************************************************************
    User has a partitioned table space where some partitions are in
    Basic Row Format (BRF) and some in Reordered Row Format (RRF).
    With SPRMRRF=DISABLE, a REORG TABLESPACE was run against this
    table space, but it failed with ABENDS0C4 in DSNIRLPG + '2B08'x
    due to rows with incorrect format being loaded.  A storage
    overlay can also happen as a result of this failure.
    
    The reported problem is caused by incorrect program logic in
    REORG TABLESPACE to handle partitions with different row
    formats when SPRMRRF=DISABLE.  The confusion on the row format
    subsequently resulted in this abend and storage overlay.
    A similar problem can happen to the LOAD REPLACE utility.
    

Problem conclusion

  • Code has been modified so that even with SPRMRRF=DISABLE, the
    REORG TABLESPACE and LOAD REPLACE utility will convert the mixed
    row format partitions to RRF when running in DB2 9 NFM.
