Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 9 for z/OS and DB2 10 for z/OS users *
    *                 of REORG TABLESPACE utility                  *
    ****************************************************************
    * PROBLEM DESCRIPTION: Data corruption with mixed row format   *
    *                      after REORG TABLESPACE completion.      *
    ****************************************************************
    * RECOMMENDATION: Apply corrective PTF when available.         *
    ****************************************************************
    User has a table space containing records in Reordered Row
    Format ( RRF ), as indicated by the header page of the pageset.
    However, as a result of DSN1COPY or other causes, the directory
    and catalog indicate the pageset is defined in Basic Row Format
    ( BRF ).
    
    When a REORG TABLESPACE is run against the table space as
    described above, the utility makes a program logic decision
    based on the row format indicator in the directory.  Due to the
    row format mismatch between the directory and the actual data,
    this inadvertently causes REORG to process the records in the
    wrong format, which can result in potential data corruption
    where records with different row format can reside in the same
    data page.  This problem can also occur when the directory
    indicates RRF while the actual data is in BRF.
    
    A similar problem can happen on row format mismatch on
    partitions of a partitioned table space, but no data corruption
    should occur on a non-partitioned table space as a result of
    REORG due to row format mismatch between the directory and the
    actual data.
    
    Additional symptoms:
    - SQL failed with ABEND04E RC00C90101 DSNIMOFR ERQUAL5022
    - SQL failed with ABEND04E RC00C90216 DSNIRNXT ERQUAL53CD
    

Problem conclusion

  • Code has been modified to enable REORG TABLESPACE to detect the
    aforementioned row format mismatch between the directory and
    the actual data, and to rectify the data records format to match
    that indicated by the directory.  This rectification is
    applicable to both partitioned and non-partitioned table space.
