OA62837: STOW RECOVERG PROCESSING FAILS WITH AN ABEND0C1 IGWDDCR2+70AE

APAR status

• Closed as program error.

Error description

• Following the successful completion of an IEBCOPY COPYGRP or
  COPYGROUP with the GENS=ALL parameter the PDSE Generation Data
  Index records in the target PDSE will have uninitialized member
  length data.
  
  
  Subsequent STOW RECOVERG or STOW RG (ReplaceGeneration)
  processing against the target PDSE is likely to fail with an
  S0C1 ABEND out of the PDSE module IGWDDCR2+70AE at the z/OS 2.5
  base level.

Local fix

• BYPASS/CIRCUMVENTION:
  Avoid IEBCOPY generation copy processing. This entitles IEBCOPY
  COPYGRP or COPYGROUP with the GEN=ALL parameter

  * PROBLEM DESCRIPTION:                                         *
  * Copying PDSE member generations using IEBCOPY with the       *
  * GENS=ALL option produces generations which can result in an  *
  * intentional 0C1 error when the generation is recovered due   *
  * to an incorrect length being written in the generation       *
  * metadata.                                                    *

  * RECOMMENDATION:                                              *
  ****************************************************************
  

Problem conclusion

• Corrected the code so new copies will have the correct internal
  length in the metadata. In addition, any generation created by
  the previous errant behavior will be tolerated and able to be
  recovered correctly.
