Error description
When using CPSM WLM to route transactions to available target regions, transactions are being routed to a region that has been set Out-of-Service when they shouldn't. This occurs on an RZ route where an OPEN failure occurs in DFHAPTC and EYU9XLOP is notified of the route failure and redriven to choose the next target. However, the route error code is always set to IOERR (DYR_IOERR) instead of the exact failure (ie. DYR_ERROUT for SYSID out of service in this case) and so the target regions WAOR control block is never updated to indicate the system is not in service.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: CPSM routes transaction to out-of- * * service AOR repeatedly. * **************************************************************** * RECOMMENDATION: * **************************************************************** In CPSM, a request is being routed from TOR to AOR. The request is using request streams by web service context switch. The request stream use distributed routing exit supply by CPSM to determine the AOR to route request to. Because the connection to the target AOR is out of service, the incorrect reason code DYR_IOERR is returned from request stream code to CPSM routing exit. This reason code make same AOR selected again by routing exit and leads to another route failure. Additional keywords: DFHPI0508 msgDFHPI0508
Problem conclusion
DFHAPTC and request streams code has been changed to return dynamic routing exit with DYR_ERROUT while the target routing region is out of service.
