PK53653: IMS CONNECT DOES NOT GENERATE EVENT 72 IF A COMMIT MODE 1 TRANSACTION TIMES OUT ON A PERSISTENT SOCKET.

APAR status

• Closed as program error.

Error description

• When a Commit Mode 1 transaction on a Persistent Socket times
  out IMS Connect returns a timeout message to the ICON client but
  it keeps the socket open and issues a read for the next message.
   However in this case IMS Connect is not generating the Prepare
  Read event (Event 72).  IMS Connect Extensions uses this event
  when deciding how to route messages.  If this event is missing
  IMS Connect Extensions may not route the message correctly, or
  it may be routed even if the transaction is not eligible for
  routing.
  

Local fix

• IMS Connect Extensions has temporary fix code if needed by the
  customer.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All IMS V9 IMS Connect users with IMS        *
  *                 Connect Extensions.                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: With IMS transaction routing            *
  *                      implemented in IMS Connect Extensions   *
  *                      (CEX) transactions are incorrectly      *
  *                      routed when the transaction request     *
  *                      follows a commit mode 1 transaction     *
  *                      that has timed out.                     *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  IMS Connect does not generate event 72 when a commit mode 1
  transaction times out on a persistent socket.  The event 72
  (Trigger event) is required by IMS Connect Extensions (CEX) as
  a framing event to delineate the timed out transaction.  As a
  result of not receiving the event 72, CEX associated the new
  transaction with the previous and maintains the routing option
  of the previous transaction.
  

Problem conclusion

• AIDS: RIDS/DCS RIDS/LMGR DCS LMGR
    GEN:
  
  *** END IMS KEYWORDS ***
  IMS Connect logic in part HWSSCVC0 has been corrected to ensure
  that event recording record 'EVENT 72' (trigger event) is
  produced for Commit mode 1 transactions that have timed out on
  persistent sockets.
  

Temporary fix
