PK95412: LOOP IN IPI4QMGR WHEN FLUSHING TRANSACTIONS FOR HIGH WATER MARK (HWM) PROCESSING

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In a combined Connect/IMS run, if the HWM is hit while trying to
  insert a new Connect transaction into the internal queue and
  removing old transactions from that queue fails to relieve the
  storage shortage (for instance, if there are no old Connect
  transactions) then a retry of the insert will again fail.
  
  Other routine possibly involved in the loop is:
  IPICPROC ( LMOD IPI4PROC )

  Loop in IPI4PROC when flushing transactions for high water
  mark (HWM) processing.
  In a combined Connect/IMS run, if the HWM is hit while
  trying to insert a new Connect transaction into the
  internal queue and removing old transactions from that
  queue fails to relieve the storage shortage (for instance,
  if there are no old Connect transactions) then a retry
  of the insert will again fail.
  

Problem conclusion

• Flush completed Connect transactions that are waiting for
  additional IMS SLDS information (which may never appear
  anyway) before attempting to flush active Connect queue
  entries.
