Customizing security

If you want to change the way IBM® MQ security operates, you 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 documentation.

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.
