Resource Recovery Services (RRS) is a subcomponent of z/OS that provides a system-wide service for coordinating two-phase commit across z/OS products. The WebSphere MQ Batch/TSO RRS adapter (the RRS adapter) provides WebSphere MQ support for z/OS Batch and TSO applications that want to use these services. The RRS adapter enables WebSphere MQ to become a full participant in RRS coordination. Applications can participate in two-phase commit processing with other products that support RRS (for example, DB2).
The RRS adapter provides two stubs; you must link-edit application programs that want to use RRS with one of these stubs.
You must also link-edit module ATRSCSS from library SYS1.CSSLIB with your application. If you use the MQI calls MQCMIT and MQBACK, you will receive return code MQRC_ENVIRONMENT_ERROR.
For information about building application programs that use the RRS adapter, see the WebSphere MQ Application Programming Guide.
