Configuring Exactly-Once Processing for a JMS Trigger
Within Integration Server, exactly-once processing is a facility that ensures one-time processing of a persistent message by a JMS trigger. The trigger does not process duplicates of the message. Integration Server provides exactly-once processing when all of the following are true:
*The message is persistent.
*The JMS trigger has an acknowledgement mode set to CLIENT_ACKNOWLEDGE.
*Exactly-once properties are configured for the JMS trigger.
Note:Software AG recommends that if you want to use exactly-once processing for JMS triggers subscribing to topics, make sure the topic uses a durable subscriber.
