PK26189: DFS070 UNABLE TO ROUTE MESSAGE RSN=0419

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The user exit routine made a call to:
  IWXMSCPR-V240-810-10/21/05-12.29PK11802 ADE
  which set bit MSPR2SRC on during an insert to the IOPCB
  in a WLR SERVER ONLY environment.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of Workload Router R243.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: DFS070 unable to route message RSN=0419 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  In a WLR server-only environment,  WLR's program routing exit
  (IWXMSCPR) attempts to route a response to the I/O PCB by
  setting the MSPR2SRC flag. In a shared queues environment, this
  may result in an A1 status code. In a data sharing environment,
  this may result in a U4095 abend. In either case, the response
  is not routed back to the I/O PCB correctly.
  

Problem conclusion

• WLR module IWXMSCPR has been updated to check if the request
  is for an I/O PCB in a server-only environment. If it is,
  WLR returns control to IMS and IMS handles the routing response
  to the I/O PCB. NOTE: WLR already checks if the request is for
  an I/O PCB in a router-server environment.
