Parameters

sessionHandle

The handle to the session that you want to recover.

You can only call this function for sessions that are not transacted. To rollback message delivery for a transacted session, use the MQRollBackSession() function. This function may be most useful if you use the MQ_CLIENT_ACKNOWELDGE mode.

All consumers deliver messages in a serial order. Acknowledging a received message automatically acknowledges all messages that have been delivered to the client.

Restarting a session causes it to take the following actions:

• Stop message delivery in this session.

• Mark all messages that might have been delivered but not acknowledged as redelivered.

• Restart the delivery sequence including all unacknowledged messages that had been previously delivered. (Redelivered messages might not be delivered in their original delivery order.)
