OA65167: CHANGES TO VSAM DATA SETS DEFINED WITH BWO(TYPEIMS) MAY NOT BE DETECTABLE TO BACKUP-WHILE-OPEN PROCESSING 23/07/24 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Updates to VSAM data sets defined with option BWO(TYPEIMS)
  during backup-while-open processing may not be detected by the
  backup utility, such as DFSMSdss.
  
  PE Information:
  Users Affected: V2R4 users with PTF for OA57833 (UJ04671)
  applied, V2R5, or z/OS 3.1 users that have VSAM data sets
  defined with BWO(TYPEIMS) that perform backup while open.
  
  User Impact: The causing APAR fixed the original problem but it
  introduced a new problem. Affected users may have invalid
  backups if the data set was modified while backup-while-open was
  
  processing.
  Local fix: Contact IBM support for ++APARs, or wait until the
  PTFs are available.

  ****************************************************************
  An uninitialized field may cause the Media Manager to fail to
  set the indicator that backup-while-open processing uses to
  check whether updates were made to the index component of the
  data set during backup processing. Additionally, the return code
  to the termination routine called by the Media Manager was
  passed incorrectly.
  

Problem conclusion

• Code changes were made to ensure that the uninitialized field is
  correctly initialized and that the return code is passed
  correctly to the termination routine.
