4.4 Defining Remote Gateways
A remote gateway is another Oracle Tuxedo Mainframe Adapter gateway (TUX, CICS, or IMS) to which TMA TCP for IMS can be connected by one or more TCP/IP connections. A remote gateway definition defines the access points that TMA TCP for IMS uses to connect to the remote gateway.
The remote gateway is defined by its IP address and port number. The remote gateway may be defined as accepting one or more concurrent outbound TCP/IP connections initiated by the local (IMS) gateway. Outbound connections are used by the IMS gateway to send IMS client requests to a remote gateway for processing by the requested service.
One or more GATEWAY TYPE=REMOTE statements are used in the configuration file to define remote gateways. Each GATEWAY TYPE=REMOTE statement defines the IP address and port number that TMA TCP for IMS uses to establish an outbound connection with a remote gateway. The GATEWAY TYPE=REMOTE statement also identifies a remote gateway by a unique logical machine ID.
The configuration file may contain multiple GATEWAY TYPE=REMOTE statements, each defining a different remote gateway. If no GATEWAY TYPE=REMOTE statements are present, then TMA TCP for IMS cannot establish outbound connections with remote gateways, and therefore cannot process IMS client requests.
The TMA TCP for IMS software can optionally be configured to supply a valid account ID and valid password when establishing an outbound session with a remote gateway.
For examples of the GATEWAY TYPE=REMOTE statement, refer to the Example Configuration Files
