### Configuring the ORB

1. In the tree component, expand the Configuration node.

2. Select the ORB node.

3. Choose the thread pool the ORB uses from the Thread Pool ID drop-down list.

   The ORB uses thread pools to respond to requests from remote clients of enterprise beans and other clients that communicate via RMI-IIOP. For more information, see To create a thread pool.

4. In the Max Message Fragment Size field, set the maximum fragment size for IIOP messages.

   Messages larger than this size are fragmented.

5. In the Total Connections field, set the maximum number of incoming connections for all IIOP listeners.

6. Select the Required checkbox if IIOP client authentication is required.

7. Click Save to save the changes, or Load Defaults to load the default values.

8. Restart the server.
