### Domain-Level Settings

You can control the following domain-level message-driven bean settings in the EJB container:

- Initial and Minimum Pool Size - Specifies the initial and minimum number of beans maintained in the pool. The default is `0`.

- Maximum Pool Size - Specifies the maximum number of beans that can be created to satisfy client requests. The default is 3`2`.

- Pool Resize Quantity - Specifies the number of beans to be created if a request arrives when the pool is empty (subject to the Initial and Minimum Pool Size), or the number of beans to remove if idle for more than the Idle Timeout. The default is `8`.

- Idle Timeout - Specifies the maximum time in seconds that a bean can remain idle in the pool. After this amount of time, the bean is destroyed. The default is `600` (10 minutes). A value of `0` means a bean can remain idle indefinitely.

For information on monitoring message-driven beans, see the Application Server Administration Console online help and the Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Administration Guide.

Note –

Running monitoring when it is not needed might impact performance, so you might choose to turn monitoring off when it is not in use. For details, see the Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Administration Guide.
