Issue:
CA Datacom MUF, which has CA CCI connection enabled, fails to start after having applied CA Common Services but it starts fine when resubmitted after few minutes. 
Environment:
CA Datacom MUF with CCI connection
Cause:
Failing MUF joblog shows the following error messages:
DB00260E - CCI ERROR - INIT 0004 0000 00 00000 
DB00223E - MULTI-USER UNABLE TO ACTIVATE CCI, FDBK = 14,0000
DB00239I - MUF TERMINATION, START PROGRAM ABEND

This means that MUF region could not connect to CA CCI and got the above errors.
Resolution:
Since it was successfully restarted later, the most likely reason for the failure of the first execution of MUF is that CA ENF was not fully activated.
In fact, when CA ENF has been correctly initialized, the MUF has successfully connected to CA CCI.
In order to avoid these error messages, MUF must be started aftee CA ENF is successfully activated.
