Refreshing Datacom External Security definitions


Article ID: 219132


Updated On:


Datacom Datacom/AD Datacom/DB


We are using the External Security definitions for Datacom/AD that were given us for our CA 7 installation, and we had to make a change because we missed one of the definitions. Even though we refreshed our security system, it doesn't look like the changes worked. Is there something special we need to do in the MUF to refresh or reset Datacom External Security settings?


Release : 15.1

Component : Datacom/AD

Component : Datacom/DB


In order to improve performance, the Datacom MUF holds certain attributes about the security configuration in its memory. Therefore, when you have made a security change—using RACF, ACF2, or Top Secret—you need to clear out the old information and reset the definitions in the MUF. You can do this either by recycling the MUF or by keeping the MUF up and running commands to reset the security settings.

You can reset the security buffers in the MUF by issuing the console command

/F mufjobname,SECURITY RESET

or you can run a DBUTLTY job with 

//SYSIN    DD  *

Once you have refreshed your security system and reset the security in the MUF, the security system changes should be active. Note that SECURITY RESET will only work on any user changes in the DxTABLE (RACF: Dx@ABLE) profiles (such as the DCTABLE used with CA 7) classes used in the MUF Startup Options called SECURITY. Changes to any of the other Datacom classes will take effect immediately, so any jobs can be submitted right away. 

Additional Information

For more information on the Security Reset process, please review the Datacom documentation for SECURITY RESET (Clearing Security Validation Buffer).
