Problem summary

• ****************************************************************
  * USERS AFFECTED: All IMS DRF V3R1 clients that employ the     *
  *                 Integrated Auxiliary Utilities; e.g. HPIC.   *
  ****************************************************************
  * PROBLEM DESCRIPTION: U384-02C ABEND with FRD9003A+FRD4100I   *
  *                      due to failed dynalloc of temp DSN.     *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  When 2 or more DRF Master Address spaces are simultaneously
  active, it is possible that a temporary dataset name is
  allocated to one MAS and a 2nd MAS attempts dynamic allocation
  for the same dataset. Previously, the DRF MAS attempting
  dynamic allocation took user abend U384-02C; however this
  situation is not serious. Now the DRF MAS skips the allocation
  and instead issues message FRD4101W and ends with RC=4.
  
  FRD4101W:
  ABOVE DSNAME NOT DELETED. PLEASE DELETE IF RPTRET=Y IS USED.
  
  Explanation of FRD4101W:
  
  This message always follows two messages: FRD9003A (dynamic
  allocation error) and  FRD4100I (identifies DSNAME that failed
  dynamic allocation). DRF was attempting to dynamically allocate
  DSNAME with DISP=(OLD,DELETE,DELETE) so that it could be
  deleted; however, the attempt failed for the reason indicated
  in FRD9003A. DSNAME is a temporary data set that
  contains messages related to the recovery; it does not contain
  recovery assets such as a DBDS, a Log, an Image Copy or a Change
  Accumulation file.
  
  If the RPTRET=Y parameter on the REPORT control card is used,
  the DSNAME should be manually deleted because it is possible
  that DRF will attempt to use the DSNAME again on a subsequent
  recovery. If RPTRET=N is used, DRF will delete this DSNAME if
  it is needed on a subsequent recovery and then allocate DSNAME
  as a new data set.
