#### To configure MDB pool settings

The pool for message-driven beans is similar to the pool for session beans. By default, the container maintains a pool of message—driven beans.

To adjust the configuration of this pool:

1. In the tree component, select the Configuration node.
2. Select the EJB Container node.
3. Click the MDB Settings tab.

   The MDB Default Pool Settings page is displayed.

4. In the Initial and Minimum Pool Size field, enter the minimum number of message beans the container creates in the pool.
5. In the Maximum Pool Size field, enter the maximum number of beans the container maintains in the pool, at any time.
6. In the Pool Resize Quantity field, enter the number of beans that are removed from the pool if they are idle for more than the time specified in Pool Idle Timeout.
7. In the Pool Idle Timeout field, enter the time, in seconds, that a bean in the pool can remain idle before it is removed from the pool.
8. Click Save.
9. Click Load Defaults if you want to restore the default values for the MDB pool settings parameters.
