Specify the DB2 Information Center port

The DB2 Information Center contains documentation for DB2® products. When you install the DB2 Information Center it functions as a server that starts up automatically when you turn on your computer. You can install the DB2 Information Center on one server to serve your entire organization. This not only eliminates the need for every user to locally maintain the DB2 Information Center, but it also allows multiple computers to access the DB2 Information Center at the same time.

The service requires a service name and a dedicated TCP/IP port. It is recommended that you accept the default values for Service name and Port number. If you need to change these values, choose values that will not conflict with existing entries in the services file:

Once the DB2 Information Center is installed, other computers will be able to access it using the newly-configured TCP/IP port. If your computer is connected to a network and is accessible by other computers, you should configure the local firewall on this computer to allow incoming TCP/IP requests to this port.

You might want to install and use the DB2 Information Center on your local computer. However, you still need to specify values in the service name and port number fields. When you try to access the DB2 Information Center on your local computer, your request comes in the form of a TCP/IP request through the DB2 Information Center port. The port therefore needs to be specified for you to use the DB2 Information Center.

To restore the installation default values after you have made changes, click Restore Default Values.

Select Configure all installed DB2 products in this installation location to use the DB2 Information Center if you want all DB2 products on this computer to use the DB2 Information Center you are now installing. If there are DB2 products already installed on your computer, this check box is selected by default. Otherwise it does not appear in this window. If you select this option, the DB2 Setup wizard modifies the DB2_DOCHOST and DB2_DOCPORT registry variables for all of the DB2 products installed on this computer.

You can change how individual DB2 products access the DB2 Information Center by using either the Tools Settings notebook in the Control Center, or the db2set command to update the DB2 registry variables. For example, assume you want all installed DB2 products to use the DB2 Information Center server you are setting up, except for one product that needs to access IBM's Web site. You can select Configure all installed DB2 products in this installation location to use the DB2 Information Center then go back and reconfigure the product that needs different access using the Tools Settings notebook or the db2set command. Alternatively, you can uncheck Configure all installed DB2 products in this installation location to use the DB2 Information Center then go back and configure the access for each product manually.
