Developing applications to use the CICS-MQ adapter

The CICS®-MQ adapter implements the IBM® MQ Message Queue Interface (MQI) for use by CICS application programs. The adapter also supports a CICS-MQ API-crossing exit. You can use this exit to intercept MQI calls as they are being run, for monitoring, testing, maintenance, or security purposes.

For transaction integrity, the adapter supports sync pointing under the control of the CICS Recovery Manager, so that units of work can be committed or backed out as required. The adapter also supports security checking of IBM MQ resources when used with an appropriate security management product, such as Security Server (previously known as RACF® ). The adapter provides high availability with automatic reconnection after a queue manager termination, and automatic resource resynchronization after a restart. It also features an alert monitor that responds to unscheduled events such as a shutdown of the queue manager.
