Fine-tuning WebSphere MQ Messaging Provider

Use this task to improve the rate at which WebSphere® MQ processes messages if you use IBM® WebSphere MQ Messaging Provider.

Before you begin

If, after you complete the tuning actions, less than 80% of your CPU capacity is used, or if the CPU usage graph shows bursts of activity, experiment with the custom property non.asf.receive.timeout. To change this property, use the administrative console.

Why and when to perform this task

CPU usage is improved by smoothing peaks, or bursts, of activity.

Steps for this task

Create the custom property non.asf.receive.timeout, on the message listener service of the application server, with a value of 2000.

This setting switches the message listener service to non-ASF mode.

Result

The rate at which WebSphere MQ processes messages is improved.
