PH69813: ABEND U0384-0000002C OCCURS IN A DRF MAS WHEN RECOVERING A SINGLE HALDB USING MULTIPLE DRF JOBS DIVIDED BY PARTITIONS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• For a HALDB (PHIDAM) with many partitions defined, when the
  partitions were divided into multiple groups, a DRF job was
  created for each group, and multiple DRF jobs with ADD IB
  (HALDB(BOTH)) specified were run in parallel, the same DSNAME
  was accidentally assigned to the IIUIN data set created by DRF
  to pass parameters to the index builder in two of the DRF jobs.
  As a result, one DRF job completed successfully, but the other
  DRF job encountered a dynamic allocation error for the IIUIN
  data set, resulting in ABEND U0384-0000002C.

  ****************************************************************
  When recovering a single HALDB using multiple DRF jobs divided
  by partitions, an ABEND U0384-0000002C occurred in a DRF MAS.
  For a HALDB with many partitions defined, when the partitions
  were divided into multiple groups, a DRF job was created for
  each group, and multiple DRF jobs with ADD IB (HALDB(BOTH))
  specified were run in parallel, the same DSNAME was accidentally
  assigned to the IIUIN data set created by DRF to pass parameters
  to the index builder in two of the DRF jobs.
  As a result, one DRF job completed successfully, but the other
  DRF job encountered a dynamic allocation error for the IIUIN
  data set, resulting in ABEND U0384-0000002C.
  Currently, DRF tries to ensure uniqueness by adding the DB name
  and timestamp to the DSNAME of the IIUIN data set it creates.
  However, those values happened to match between the two DRF
  MAS jobs.
  

Problem conclusion

• DRF has been modified to additionally set the MAS Job ID in
  DSNAME of IIUIN and HFPSYSIN data sets so that it can guarantee
  the uniqueness of DSNAME even when the timestamps match.
