restart CKTI instance after MQRC 2373 failure

Currently an instance of the CKTI is terminated when it encounters a MQRC 2373 failure due to a failed WMQ application structure when using shared queues.. Once the structure is successfully recovered we have to manually restart that instance of the CKTI.

    There has been no reponse from the customer about if an automation procedure was put in place after the CF structure was recovered. We have no plans to provide such function.

    In the PMR associated with this RFE there was reference to "working with the automation team to restart CKTI once the structure is recovered". Were you table to put such a procedure in place ?


    WMQ does not have any mechanism (like an event notification) that CICS could use to know when a CF structure (or other transient condition) has recovered. This has been considered by WMQ but is not going to be delivered any time soon, if ever.

    Even If such a mechanism were implemented, it's not clear how CICS would know that starting/restarting CKTI would be a sensible reaction. If CICS actually knows that CKTI is interested in the recovery that just happened (not sure how it would know that) then it could start/restart CKTI.

    A  more viable alternative, which might also work for other recoverable situations, would be for CKTI itself to retry periodically (say every minute).

    However, none of the above are necessarily an enormous improvement over doing it using automation.
