    * PROBLEM DESCRIPTION: REORG TABLESPACE on a compressed PBG    *
    *                      table space compresses or decompresses  *
    *                      data records with an incorrect          *
    *                      compression dictionary.                 *

    ****************************************************************
    User ran a REORG TABLESPACE utility on a partition-by-growth
    table space, which was defined with the COMPRESS YES attribute
    where different partitions have different pre-existing
    compression dictionaries built prior to REORG.  During REORG
    execution, the utility failed as follows:
    
    (1) If KEEPDICTIONARY is specified and REORG is run against
        disjoint partition ranges, REORG might decompress data
        records using the wrong decompression dictionary when the
        PBG records are redistributed across partitions.
    
    (2) For REORG TABLESPACE SHRLEVEL CHANGE execution, concurrent
        DML resulting in PBG record data movement can also result
        in the usage of incorrect compression dictionaries in
        log apply processing.
    
    A variety of symptoms can occur in the aforementioned scenarios
    due to the incorrect decompression of data records.  Some of the
    known symptoms include :
    
    - ABEND04E RC00C90101 in DSNIREFS ERQUAL535C
    - ABEND04E RC00C90206 in DSNIIDIS ERQUAL5002
    - ABEND04E RC00C90101 in DSNKINSL ERQUAL5033
    - ABEND04E RC00E4030F in DSNURLAP OFFSET4394
    - ABEND0C7 ABENDS0C7 in DSNURWBF OFFSET51DC
    - ABEND0C1 ABENDS0C1 ABEND0C4 ABENDS0C4 due to STORAGE OVERLAY
      involving incorrectly decompressed data record
    

Problem conclusion

  • Code has been modified to ensure the correct compression
    dictionaries are used by REORG in the aforementioned scenarios.
