PI53237: PRE-ROUTING EXIT NOT CALLED FOLLOWING PING REQUEST IN THE SAME PERSISTENT SESSION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The pre-routing exit is not called following a PING request in
  the same persistent session. The Target Datastore in event x'3E'
  for the transaction that is not routed may show a value of
  PING_IMS in some cases. A circumvention is provided in module
  CEXEXRTR that detects the missing trigger event x'48' and clears
  the residual information from the PING request.
  
  Summary of changes:
  The root cause of the problem is a missing TRIGGER event
  TYPE=MESSAGE (EVENT ID=X'48') following the PING response. This
  results in residual information about the session and the PING
  request causing CEXEXRTR to not call the pre-routing exit.

  1. The pre-routing exit is not called following a PING request
     in the same persistent session. The Target Datastore name in
     event x'3E' for the transaction that is not routed may show
     a value of PING_IMS in some cases.
  2. The root cause of the problem is a missing TRIGGER event
     TYPE=MESSAGE (EVENT ID=X'48') following the PING response.
     This results in residual information about the session and
     the PING request causing CEXEXRTR to not call the
     pre-routing exit.
  

Problem conclusion

• A circumvention is provided in module CEXEXRTR that detects
  the missing trigger event x'48' and clears the residual
  information from the PING request.
