Security considerations

Considerations for running your database under the XA model.

The following information is provided for guidance only. In all cases, refer to the documentation provided with the database manager to determine the security implications of running your database under the XA model.

An application process denotes the start of a global unit of work using the MQBEGIN verb. The first MQBEGIN call that an application issues connects to all participating databases by calling their client library code at the xa_open entry point. All the database managers provide a mechanism for supplying a user ID and password in their XAOpenString. This is the only time that authentication information flows.

Note that, on UNIX and Linux platforms, fastpath applications must run with an effective user ID of mqm while making MQI calls.
