Error description
Users intermittently receive the following message at their 3270 terminals when invoking transactions defined to CICSPlex SM with an affinity lifetime of LOGON , SIGNON , PCONV or DELIMIT . . EYUWR0003W The Affinity AOR applid is not available because the AOR job is different. . This message is incorrectly issued and misleading in this instance as it is issued when there are no available sessions for routing the transaction to the target AOR. Users should receive the following message when the route error is due to no available sessions. . EYUWR0002W No sessions are available for route to AOR (typeid). . Additional Symptom(s) Search Keyword(s): WLMATAFF view shows affinity has been deleted / removed prematurely for a LOGON SIGNON PCONV or DELIMIT affinity lifetime.
Local fix
Increase the number of send sessions in the SESSION definition in the TOR router.

If the route fails and the affinity was created for this route, method EYU0WDIN (WDIN) should delete the uncommitted affinity and allow CPSM to select an alternate target region. If the affinity was already committed due to a prior successful route, it should remain active and the route should fail because the affinity target region is not available. A logic error in WDIN causes this process to be reversed.
Problem conclusion
WDIN has been updated to remove the logic error.

Comments
Invalid results may occur when the route of a transaction that has a CPSM WLM affinity defined for it results in a route failure. - if the affinity exists when the route is attempted, the affinity will be invalidly deleted. - if the affinity does not exist when the route is attempted, the route will not be attempted to any other available target regions. When a transaction that is associated with an affinity is executed, CPSM will build the affinity when called by CICS for route selection. If the route does succeed, CPSM commits the affinity. If the route fails, if the affinity was created for this route, method EYU0WDIN (WDIN) should delete the uncommitted affinity and allow CPSM to select an alternate target region. If the affinity was already committed due to a prior successful route, it should remain active and the route should fail because the affinity target region is not available. A logic error in WDIN causes this process to be reversed. WDIN has been updated to remove the logic error.
