Thread pool configuration XML elements

The following element types for thread pools are subtypes of the abstract <threadpool> type:

<j2ee-managed-threadpool>

This type of thread pool supports JMS integration and JSR-236 concurrency. Use this type for running in IBM WebSphere, JBoss, or Oracle Weblogic environments. Use this type of thread pool for running in a JBoss environment. This type does not support an inbound JMS integration that runs in dev mode on the Jetty platform.

<unmanaged-threadpool-cached>

This type of thread pool supports reusing an available thread that is not in use and creating a new thread if one is not available.

<unmanaged-threadpool-fixed>

This type of thread pool uses a fixed number of threads.

<unmanaged-threadpool-forkjoin>

This type of thread pool uses the same number of threads as the number of CPUs that the JVM detects. Use this type for a self-managing default thread pool.

<unmanaged-threadpool-single>

This type of thread pool uses a single thread.

Some of these types contain attributes or subelements specific to the type.

The base configuration provides definitions for managed and unmanaged thread pools that use default attribute values. These definitions are for development use only and must not be used in a production environment. For best performance, create your own custom thread pool with a unique name and tune that thread pool for the specific work you need, such as your JMS work. Then, update the thread pool settings to include the JNDI name for your new thread pool.

For testing inbound JMS integration in dev mode on the Jetty platform, use an unmanaged thread pool, not a thread pool of type j2ee-managed-threadpool.
