PI53660: PRF LOGIC FAILS TO GET CONTROL AFTER ABEND SX22 S222

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The combination of PRF V2.1 and BBM V1.2 allowed batch backout
  to be run as part of the cancellation process when an Sx22 abend
  occurred. This happened because the logic to run batch backout
  was part of the mainline ESTAI processing for the application
  task which BBM attached. In PRF V2.2, this logic was removed
  from the ESTAI mainline code and placed into the mainline PRF
  logic. Due to the way an Sx22 abend works, the mainline PRF
  logic does not get control, so backout is not run. This causes
  database availability issues for customers because batch
  (DLI/DBB) jobs need to be restarted to allow the backout to
  occur.
  

Local fix

• Restart the batch job; PRF will cause backout to run at job
  start when backout is not run at job end.

  * PROBLEM DESCRIPTION: As part of PRF V2.2, application abend  *
  *                      processing changed in a way that caused *
  *                      backout processing to be skipped for    *
  *                      jobs that encounter an abend that       *
  *                      cannot be retried. This normally        *
  *                      happens in Sx22 abends or out-of-       *
  *                      memory conditions.                      *

  ****************************************************************
  PRF V2.1/BBM V1.2 contained all application backout logic in an
  ESTAI exit that was activated as part of the application ATTACH
  process. This logic was modified and moved to the mainline PRF
  logic in PRF V2.2. This meant that an abend that could not be
  retried, such as an Sx22 abend, would cause PRF to skip
  backout processing during abend processing because the PRF
  mainline code would not get control. Note that in this case,
  job restart would cause PRF to proceed with application
  backout processing prior to application restart.
  

Problem conclusion

• PRF abend processing was modified so that a new PRF ESTAE
  routine would get control in case of non-retryable abends. This
  ESTAE routine calls the PRF backout processor before
  percolating.
