Error description

  • If REORG takes partition inline copy on tape, it gets S0878
    abend.
    

Local fix

  • If possible reduce number of partitions processed in the REORG
    or use a single image copy data set for all partitions.

    * PROBLEM DESCRIPTION:                                         *
    * ABENDS878 during REORG TABLESPACE in RELOAD phase with       *

    ****************************************************************
    * RECOMMENDATION:                                              *
    * Apply corrective PTF when available                          *
    ****************************************************************
    Buffers allocated for each inline image copy data set were not
    taken into account when calculating the degree of unload/reload
    parallelism and memory assigned to each sort subtask. If many
    partition level image copy data sets were allocated this could
    exceed the available memory resources resulting in S878 abends.
    
    If REORG TABLESPACE with partition level inline image copies is
    working on a large number of partitions this could also affect
    non parallel unload/reload processing.

Problem conclusion

  • Code has been changed to take data set buffers for inline image
    copy data sets into account when calculating memory assigned to
    each sort subtask.
