Message Acknowledgement
For each message type (that is, each type of channel), TIBCO BusinessEvents acknowledges the receipt of messages according to the protocol of the messaging system.
Some messages do not require acknowledgement. For example reliable Rendezvous messages do not require acknowledgement.
JMS messages might require acknowledgement, depending on the message acknowledgement mode (see JMS Message Acknowledgement Mode in TIBCO BusinessEvents Developer’s Guide for a list of modes).
An event is acknowledged as follows:
- In a preprocessor: Immediately after the event is consumed.
- During a run to completion (RTC) cycle:
- With Cache or Store OM, after the post RTC phase.
- With In Memory OM, after the post RTC phase, but only if the event has been explicitly consumed.
