Using syncpoint coordination

Within WebSphere MQ, one of the roles of the queue manager is syncpoint control within an application. If an application runs on an WebSphere MQ base client, it can issue MQCMIT and MQBACK, but the scope of the syncpoint control is limited to the MQI resources. The WebSphere MQ verb MQBEGIN is not valid in a base client environment.

Applications running in the full queue manager environment on the server can coordinate multiple resources (for example databases) via a transaction monitor. On the server we can use the Transaction Monitor supplied with WebSphere MQ products, or another transaction monitor such as CICS. We cannot use a transaction monitor with a base client application.

We can use an external transaction manager with a WebSphere MQ extended transactional client. See What is an extended transactional client? for details.
