You must configure TCP/IP for the instance to enable remote clients to connect to the database server. You will also use this connection information to configure each client to access this instance.
You can configure TCP/IP later, using the Control Center or the Command Line Processor (CLP). For information on manually updating the TCP/IP settings, see http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/topic/com.ibm.db2.luw.qb.server.doc/doc/t0004727.html
The TCP/IP Service name and Port number are used by a DB2® instance to listen for incoming DB2 connections.
If the DB2 Setup wizard detects TCP/IP for the current installation, the Configure radio button is selected automatically.
The DB2 Setup wizard generates a default value for the Service name, which is the name that is associated with the port number.
The DB2 Setup wizard also generates a default value for the Port number, which designates the particular TCP/IP port on which the server listens for requests from IBM® Data Server clients.
It is recommended that you accept the default values for Service name and Port number unless they conflict with other services on your computer. If you need to change these values, choose values that will not conflict with existing entries in the services file. Both fields are mandatory and must be unique on the computer.
The Service name cannot exceed 14 characters.
The Port number value must be in the range 1024 to 65535.
To clear the values you have typed and restore any values that are generated by the DB2 Setup wizard, click Restore default settings.
If the DB2 Setup wizard does not detect TCP/IP, the Do not configure at this time radio button is selected automatically.
If you want to configure TCP/IP at this time, click Configure and type your own values in the appropriate fields.
Click Autostart the instance at system startup to automatically start the instance. Automatically starting the instance eliminates the need to manually start the instance each time you start your system.
