10 Configuring the TCP/IP Communications Package for IMS Connect

Read this chapter if your gateway uses the TCP/IP communication protocol. It describes how to configure the TCP/IP for IMS Connect feature. TCP/IP is a communication protocol that is already a part of your operating system. No third-party protocol software is required. This chapter contains the following section:

10.1 Configuring TCP/IP for IMS Connect on UNIX Platforms

The configuration process requires you to enter parameters that are unique to your system to properly configure TCP/IP. Ask your network administrator to provide you with a list of the installation parameters that you require to complete the configuration process.

Basic configuration consists of assigning a host name, an IP address, and a Network Mask to a given network interface. This basic configuration must already be done by your systems administrator. If not, contact your systems administrator to have this configuration completed before you continue.

Additional configuration consists of defining a Name Server IP Address or creating entries in the Hosts file on the local system. Name servers translate host names into IP addresses when queried for a particular host name. The hosts file provides this same functionality, but in a nonnetwork participating manner.

For local configuration (the gateway is on the same system), you might want to use the loopback address. The IP address is and is typically given the local name (localhost or loopback) in the Hosts file. Using the loopback address reduces the amount of network overhead by handling the traffic internally without actually talking to the network.


Oracle Database Gateway for APPC using TCP/IP support for IMS Connect has specific initialization file parameters. These parameters are located in $ORACLE_HOME/dg4appc/admin/initsid.ora. For information about these parameters, refer to "Gateway Initialization Parameter File Using TCP/IP".

For more information about configuring TCP/IP for a particular host operating system, refer to the appropriate platform and operating system installation and configuration guides.

When you have finished configuring TCP/IP for IMS Connect for the gateway, proceed to Chapter 11, "Configuring the OLTP" to complete and verify the configuration process.
