target journal

See queue journal.

target journaling

The process Message Queuing uses to respond when messages are removed from a queue. When target journaling is enabled, a copy of each message removed from a destination queue is stored in the journal of the queue.

transaction boundaries

The boundaries that define a group of messages sent within a single transaction. When transactional messages are sent to a single destination queue, the receiving application can use the transaction boundaries to verify that first and last messages sent in a transaction have not been lost by the application while the messages were waiting in the queue.

transactional dead-letter queue

A system-generated transactional queue located on each source computer. It is used to store a copy of each unconfirmed message sent within a transaction. Looking into this queue after the proper interval gives the sending application a guaranteed way to verify that the message was delivered and processed by the receiving application.

transaction level

A queue setting that indicates whether the queue accepts transactional or nontransactional messages. This setting is set when the queue is created and cannot be changed later.

transactional message

A message sent as part of a transaction. Transaction messages must be sent to transactional queues.

transactional queue

A queue that contains transactional messages. Transactional queues can only contain transactional messages, which are messages sent within a transaction.

transaction status queue

A system-queue that contains the read receipt acknowledgments returned by connector applications. It is specified by setting the message's PROPID_M_XACT_STATUS_QUEUE property. The transaction status queue must be a transactional queue.


The user account, group account, or logon session to which an access control entry (ACE) applies. Each ACE in an access control list (ACL) applies to one trustee and contains one security identifier (SID) that identifies the trustee.
