  * PROBLEM DESCRIPTION: ABEND0C4 RC10 at DSNUCBMT + x'8C66'     *
  *                      occurred during RECOVER PARALLEL of a   *
  *                      list of objects with PI05573/UI15308/   *
  *                      UI15309 applied.                        *
  ****************************************************************
  * RECOMMENDATION: Apply corrective PTF when available.         *
  ****************************************************************
  With PI05573 / UI15308 / UI15309 applied, RECOVER PARALLEL of a
  list of objects may ABENDS0C4 RC10 at DSNUCBMT OFFSET8C66
  because RECOVER utility may use an incorrect index to check for
  subtasks. The problem happens when there are not enough tape
  drives to support the degree of parallelism.
  
  This problem happens intermittently and a similar problem may
  also happen with COPY PARALLEL.
  
  Additional Keywords: DSNUBBID OFFSET6FC4
  

Problem conclusion

• RECOVER and COPY utilities have been modified to use the correct
  index to check for subtasks during parallel processing.
