The MUF can be shut down in the following ways:
Note: In z/OS, a sample shutdown proc AD14STOP is provided in the CUSPROC PDS data set.
The DBUTLTY COMM OPTION=EOJ function or the COMM EOJ console command provides a controlled shutdown. After receiving the EOJ command, the MUF does not allow any new tasks or programs to start accessing the DBMS. However, the MUF does not stop until all existing tasks or programs using the MUF have finished. This could apply to CICS, CA Datacom Server, TSO and other CA products processing, if they are being used. A COMM STATUS reflects jobs are still running but it also reflects an EOJ IN PROGRESS.
For more information about both options, see the CA Datacom/DB DBUTLTY Reference Guide. AD14STOP is a sample job provided from the install.
Note: To help determine the problem if the MUF abends, CA Support must have the region dump and the report or snaps produced by the MUF.
