## To configure the ORB

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

2. Select the instance to configure:

   - To configure a particular instance, select the instance’s config node. For example, for the default instance, `server`, select the `server-config` node.

   - To configure the default settings for future instances that use a copy of `default-config`, select the `default-config` node.

3. Select the ORB node.

4. 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 About Thread Pools and To create a thread pool.

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

   Messages larger than this size are fragmented.

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

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

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

9. Restart the server.
