MSMQ Glossary: X
A transaction that is coordinated by an XA-compliant transaction manager. MS DTC can enlist in an XA transaction as an XA-compliant resource manager and act simultaneously as a subordinate transaction manager that controls a Message Queuing resource manager. In such a transaction scheme, Message Queuing implicitly invokes the current XA transaction.
A keyword that indicates that the transactional connector queue is requested.
