Configuring TCP/IP Communications on the DB2 Connect Workstation

This section assumes that TCP/IP is functional on the DB2 Connect and host systems.

See Software Requirements for the communication protocol requirements for your platform. See Possible Client-to-Server Connectivity Scenarios for the protocols supported for communication between your particular client and server.

To set up TCP/IP communications between your DB2 Connect workstation and a host database server, perform the following steps:

Step  1.

Identify and record parameter values.

Step  2.

Configure the DB2 Connect workstation:

  1. Resolve the host's IP address.

  2. Update the services file.

Step  3.

Catalog the TCP/IP node.

Step  4.

Catalog the database.

Step  5.

Catalog the database as a Database Connection Service (DCS) database.

Step  6.

Bind utilities and applications to the database server.

Step  7.

Test the host connection.

Due to the characteristics of the TCP/IP protocol, TCP/IP may not be immediately notified of the failure of a partner on another host. As a result, a client application accessing a remote DB2 server using TCP/IP, or the corresponding agent at the server, may sometimes appear to be hung. DB2 uses the TCP/IP SO_KEEPALIVE socket option to detect when there has been a failure and the TCP/IP connection has been broken.

If you are experiencing problems with your TCP/IP connection, refer to the Troubleshooting Guide for information on how to adjust this parameter and other common TCP/IP problems.
