The IMS adapter

 

 

Note to users

If you are using the IMS™ adapter from a WebSphere MQ for z/OS system, ensure that IMS can obtain sufficient storage to accommodate messages up to 100 MB long.

The IMS adapter provides access to WebSphere MQ for z/OS resources for:

To use these resources, the programs must be running in task (TCB) mode and problem state; they must not be in cross-memory mode or access-register mode.

The adapter provides a connection thread from an application task control block (TCB) to WebSphere MQ. The adapter supports a two-phase commit protocol for changes made to resources owned by WebSphere MQ for z/OS, with IMS acting as the syncpoint coordinator.

The adapter also provides a trigger monitor program that can start programs automatically when certain trigger conditions on a queue are met. For more information, see Starting WebSphere MQ applications using triggers.

If you are writing batch DL/I programs, follow the guidance given in this book for z/OS batch programs.
