Setting up Db2 for z/OS as a TCP/IP requester

Much of the processing in a distributed database environment requires the exchange of messages with other locations in the network.

About this task

When Db2 for z/OS acts as a requester, it can connect applications that run on the z/OS system to remote database servers, including Db2 for z/OS, Db2 for Linux®, UNIX, and Windows, Db2 for i, and Db2 server for VSE and VM.

In its role as a requester, Db2 for z/OS accepts Db2 location names and translates them into TCP/IP addresses. It uses the communications database (CDB) to register location names and their corresponding network parameters. The data that is stored in the CDB enables Db2 to pass the required information when making distributed database requests over TCP/IP connections.

Procedure

To set up Db2 for z/OS as a requester:

  1. Define the Db2 for z/OS requester to the local TCP/IP system.
  2. Identify the remote data sharing groups to which applications can connect.
