Define the messaging characteristics of the connector as a JMS producer:
Select to store messages from this producer (the connector) in the database for the queue or topic until they are retrieved or they expire. Clear to store messages in memory until they are retrieved or they expire.|
If the queue or topic uses priority levels, enter a priority level for the messages. The range is 0 (lowest) to 9 (highest).|
The length of time, in milliseconds, the message stays in the queue or topic
before it expires. If the message is not retrieved during this time period, the JMS
provider destroys the message. To specify that a message never expires, either leave this field blank or enter 0.
