Sun Java System Message Queue 4.3 Developer's Guide for C Clients



The handle to the transacted session that you want to commit.

A transacted session supports a series of transactions. Transactions organize a session’s input message stream and output message stream into a series of atomic units. A transaction’s input and output units consist of those messages that have been produced and consumed within the session’s current transaction. (Note that the receipt of a message cannot be part of the same transaction that produces the message.) When you call the MQCommitSession function, its atomic unit of input is acknowledged and its associated atomic unit of output is sent.

The completion of a session’s current transaction automatically begins the next transaction. The result is that a transacted session always has a current transaction within which its work is done. Use the MQRollBackSession() function to roll back a transaction.
