Performance considerations for WebSphere MQ queue destinations

To optimize performance, configure the queue destination properties to best fit your message-driven beans or other applications that use the queue destinations.

For example:

To ensure that there are enough underlying WebSphere MQ resources available for the queue, you must ensure that you configure the queue destination properties adequately for use by your message-driven beans or other applications that use the queue.

You should also consider queue attributes of the internal JMS server that are associated with the queue name. Inappropriate queue attributes can reduce the performance of WebSphere operations.

You should also consider the queue attributes associated with the queue name you created with WebSphere MQ. Inappropriate queue attributes can reduce the performance of WebSphere operations. You can use WebSphere MQ commands to change queue attributes for the queue name.

BOQNAME
The excessive backout requeue name. This can be set to a local queue name that can hold the messages which were rolled back by the WebSphere applications. This queue name can be a system dead letter queue.
BOTHRESH
The backout threshold and can be set to a number once the threshold is reached, the message will be moved to the queue name specified in BOQNAME.
INDXTYPE
Set this to MSGID. This causes an index of message identifiers to be maintained, which can improve WebSphere MQ retrieval of messages.
DEFSOPT
Set this to SHARED (for shared input from the queue).
SHARE
This must be specified (so that multiple applications can get messages from this queue).
