    * RECOMMENDATION:                                              *
    * Apply corrective PTF when available                          *
    ****************************************************************
    In a rare situation, a Db2 unit of recovery allocated
    a data space map page before it inserted into a data page,
    this UR later became postponed abort. During postponed
    abort recovery, Db2 failed to remove the Restart-pending
    (RESTP) or Advisory restart-pending (AREST) status from the
    table space after the postponed abort UR had been recovered.
    

Problem conclusion

  • Db2 code has been changed to remove the Restart-pending
    (RESTP) or Advisory restart-pending (AREST) status from a
    table space after the postponed abort URs changing this table
    space are recovered.
