Customizing security

To change the way IBM MQ security operates, we must do this through the SAF exit (ICHRFR00), or exits in your external security manager.

To find out more about RACF exits, see the z/OS Security Server RACROUTE Macro Reference manual.

Note: Because IBM MQ optimizes calls to the ESM, RACROUTE requests might not be made on, for example, every open for a particular queue by a particular user. Parent topic: Set up security on z/OS
