JMSX Properties

Use this tab to re-specify which JMS-defined properties should be set by Message Queue.

Message Queue supports a number of JMS-defined attributes, though at the cost of resources. To conserve resources, you should determine which of these properties are actually needed by the client application and enable setting of those properties by clicking the appropriate checkbox.

Enable JMSXAppID Message Property Specifies whether Message Queue should set the JMS-defined property, JMSXAppID (identity of application sending the message), on produced messages. Default: false

Enable JMSXUserID Message Property Specifies whether Message Queue should set the JMS-defined property, JMSXUserID (identity of user sending the message), on produced messages. Default: false

Enable JMSXProducerTXID Message Property Specifies whether Message Queue should set the JMS-defined property, JMSXProducerTXID (transaction identifier of the transaction within which this message was produced), on produced messages. Default: false

Enable JMSXConsumerTXID Message Property Specifies whether Message Queue should set the JMS-defined property, JMSXConsumerTXID (transaction identifier of the transaction within which this message was consumed), on consumed messages. Default: false

Enable JMSXRcvTimestamp Message Property Specifies whether Message Queue should set the JMS-defined property, JMSXRcvTimestamp (the time the message is delivered to the consumer), on consumed messages. Default: false
