After upgrading CA Datacom/DB 15.1 from version 15.0, the 15.1 MUF startup terminated:

The CA Datacom/DB 15.1 MUF startup options was missing the SECURITY options that were used with 15.0.
Note the informational message in the MUF startup indicating the external security was active:
DB00231I - EXTERNAL SECURITY LEVEL 05 ACTIVE
Determined that 15.0 MUF startup options included the following SECURITY statements that were missing from the 15.1 startup:
DB01900I - SECURITY DBDTSSR,DBDTRAT,DBDTSCI,DBDTRSR,DBDTSQL,DBDTRCI
DB01900I - SECURITY DBDTSCQ,DBDTRCQ,DBDTRAQ,DBDTSQQ DQ PATHS FOR LEVEL 05
Once these were added, the 15.1 MUF started successfully.
