Adjusting the queue depth of a monitor model

You can use the WebSphere® Application Server administrative console to adjust the maximum queue depth for a monitor model.

Before you begin

Before you begin this task, you must log in to the WebSphere Application Server administrative console.

For several reasons, you might want to increase the maximum queue depth for a monitor model in the following situations:

When maintenance is planned for machines on which the monitor model is running
When 6.0.2 emulation has encountered an error causing the Java™ Message Service (JMS) queue to back up until the problem is resolved
When the monitor model cluster requires more capacity and, until the capacity comes online, the emitter is producing more messages than the existing hardware can accommodate

To adjust the queue depth of a monitor model, complete the following steps:

In the WebSphere Application Server administrative console, click Service Integration > Buses.
On the Buses page, click MONITOR.your_cell.Bus.
Under Destination resources, click Destinations.
On the Destinations page, click wbm_your_model_Q_Destination.
Under Message points, click Queue Points.
Click your queue.
Under the Configuration tab in the High message threshold field, enter the new message threshold number.
Click Apply or OK.
To save your changes to the master configuration, click Save.
Repeat this procedure for wbm_your_model_Q_A_Destination.
