Installation and Configuration Supplement

Before You Begin

To complete the steps in this section, you should know how to start the Control Center. For more information, see Appendix A, Basic Task Knowledge.

Before you can use the Control Center, ensure that you have a running Administration Server. By default, the installation program created and configured an Administration Server for you.

About the Control Center and Communications Protocols

The Control Center is a graphical tool used to administer DB2 databases. The Control Center's setup communications function allows you to display the protocols and configuration parameters that a server instance is configured to use. It also allows you to modify the parameter values of a configured protocol, as well as add or delete protocols.

When you add support for a new protocol to the server system, the setup communications function detects and generates server instance parameter values for the new protocol. You can accept or modify these values before use. When you remove support for an existing protocol from the server system, the setup communications function detects the protocol that has been removed and disables its use by the server instance.

You can add a protocol that has not been detected, however, you must supply all of the parameter values required before you proceed.

The setup communications function can be used to maintain communications for both local and remote server instances, provided that an Administration Server is running on the server system.

Modifying an instance's communications settings may require you to update the database connection catalogs on the client. You can do this by: Using the Client Configuration Assistant on the client, select the database connection you want to change and then click on the Properties push button. This will launch a SmartGuide that will help you with the changes. For more information on cataloging using the Client Configuration Assistant, see Configuring Client-to-Server Communications Using the Client Configuration Assistant. Using the command line processor on the client to uncatalog and recatalog the node, depending on the values changed on the server.
