After a CA Datacom MUF abend and restart, the CA Datacom CICS Service Facility is not reconnecting automatically to the MUF.
Release : 15.1
Component : CA DATACOM CICS SERVICES
After a MUF abend, the CA Datacom CICS Service facility has the capability to reconnect to the MUF automatically as long as the application work load keeps coming in and the failed MUF gets restarted and fully activated.
There is no need for manual intervention if all the steps in the automatic reconnect process complete successfully.
If the MUF and the application CICS regions are up and running and connected together and actively processing requests, when the MUF fails at some point, an application request from CICS to MUF will receive a Datacom Return Code of 86.
This return code will trigger the following process in the CICS Service facility :
Any abends during this process can prevent the auto-reconnect process from being completed successfully.
If the CICS Service Facility is not reconnecting within a couple of minutes of the MUF restarting and activating do the following:
This will allow any other non-DATACOM application work to proceed uninterrupted and would act just like a CICS recycle for the CA Datacom related applications.
Alternatively perform a recycle of the CICS region.
