jms.TransportOptimized

The jms.TransportOptimized property determines if the WIP (work in progress) is optimized. You must have a WebSphere MQ provider to optimize the WIP. For optimized WIP to operate, the messaging provider must be able to:

  1. Read a message without taking it off the queue
  2. Delete a message with a specific ID without transferring the entire message to the receiver's memory space
  3. Read a message by using a specific ID (needed for recovery purposes)
  4. Track the point at which events that have not been read appear.

The JMS APIs cannot be used for optimized WIP because they do not meet conditions 2 and 4 above, but the MQ Java APIs meet all four conditions, and hence are required for optimized WIP.

This property is valid only if the value of DeliveryTransport is JMS and the value of BrokerType is ICS.

The default value is false.
