PI78153: OTMA CLIENT TIMEOUT CANNOT BE CONFIGURED FOR WOLA

Fixes are available

APAR status

Closed as program error.

Error description

If an IMS region is unable to process a WOLA request for some
reason, such as the target IMS transaction is not available,
there is no way to cancel the request to IMS.  The connection
wait timeout provided in the managed connection factory or
connection specification is not honored for requests to IMS
using OTMA.

Local fix

In some instances a dispatch timeout or transaction timeout can
be used to terminate the offending servant region,
CAVEAT:::  But this can lead to frequent recycling of servant
regions if the IMS region is configured incorrectly.  So it is
offered with caution.

*                  Server V8.5 and V9.0                        *
****************************************************************
* PROBLEM DESCRIPTION: The OTMA request timeout is not         *
*                      honored when submitting requests via    *
*                      WOLA.                                   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The connection wait timeout provided on the WebSphere
Optimized Local Adapters (WOLA) connection factory is not
honored when submitting OTMA requests to IMS.  There is no
way to interrupt an OTMA request after a fixed amount of time
has elapsed.

Problem conclusion

The connection factory and interaction spec were updated to
allow OTMA requests to be interrupted after a fixed amount of
time has elapsed.
