|Monitoring components on Geronimo Server||Monitoring the health of the Apache Geronimo server||Server uptime and resource utilization|
The Thread Pools portlet provides information about threads being used by the Geronimo server.
You can click Monitor to see statistics about maximum threads in the pool, lowest number recorded, highest number recorded, and threads in use for ConnectorThreadPool and DefaultThreadPool.
Note: Currently not all threads used by the server come from one of these thread pools. Future enhancements will enable additional server components to use these pools.
Applications which have requirements for a larger pool size may require you to increase the default values of 30 for ConnectorThreadPool and 500 for DefaultThreadPool. For example, assume that your application has two HTTP connectors that demand 100 simultaneous connections each. The ConnectorThreadPool size needs to be increased to 200 and the DefaultThreadPool size to 700.
The console allows you to monitor the utilization of the thread pools, but it does not yet allow you to configure the maximum pool size. Use the following procedure to modify the configuration.
You must always stop the server before changing config.xml. Any changes made to config.xml while the server is running will be lost. When the server stops, it writes a new copy of config.xml so it contains any configuration changes made while the server was running.
where 500 is replaced with the new pool size.
where 30 is replaced with the new pool size.
Note: ConnectorThreadPool is used in J2EE Connector Architecture (JCA), and DefaultThreadPool is used by Web container and System database.
