When the PowerCenter Integration Service writes a value to the JMSDeliveryMode field in the target, it writes 1 for non-persistent and 2 for persistent.
When the target is a WebSphere MQ JMS provider, and the PowerCenter Integration Service writes a value of -1 to the JMSDeliveryMode field or JMSPriority field in the target, WebSphere MQ JMS writes a value of 4 to the field, and the session completes successfully.
