    * RECOMMENDATION:                                              *
    ****************************************************************
    While REORG is running on a multi-table table space, DB2 doesn't
    include the size of a dropped table when determining the size of
    the storage to allocate for a work area that is used for
    decompressing or editproc decoding records.
    Later it tries to use the work area, which leads to the storage
    overlay because the allocated storage is of insufficient size.
    

Problem conclusion

  • DB2 code has been modified to ensure that the work area is of
    maximum size needed to handle any dropped tables.
