OA46164: KDS RECORD UPDATES MADE WHEN CCMK IS RUNNING WITH HCR77A1 IN THESYSPLEX WITH OLDER RELEASES MAY RESULT IN KDS RECORD CORRUPTION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• KDS update requests are sent to the master system during a CCMK
  operation.  When a HCR77A1 system shares a KDS with pre-HCR77A1
  systems, the HCR77A1 system may cause an incorrectly formatted
  KDS upate to be written to the KDS which leads to corruption of
  the KDS record.  The potential for the KDS record truncation or
  corruption exits only for records updated during the CCMK.

  Problem Summary:
  ICSF may corrupt KDS records if a Coordinated Change Master Key
  operation is performed while an HCR77A1 system is sharing a KDS
  with a pre-HCR77A1 system and KDS updates are being performed.
  

Problem conclusion

• ICSF has been changed to send the correct KDS update requests
  when a Coordinated Change Master Key operation is performed
  while HCR77A1 systems are sharing a KDS with pre-HCR77A1
  systems.
