GATEWAY TYPE=REMOTE statements define access to remote systems by the IMS gateway. In particular, each GATEWAY TYPE=REMOTE statement specifies:

• The IP Address to use to establish a TCP/IP connection (that is, connect) with the remote gateway
• The Port Number to use to establish a TCP/IP connection (that is, connect) with the remote gateway
• The Account ID and Password (if used) that must be supplied to establish an outbound session with the remote gateway
• The minimum and maximum number of concurrent, outbound sessions that are established with the remote gateway
• If you specify a value other than zero for the minimum number of sessions, TMA TCP for IMS attempts to establish the specified number of outbound sessions with the remote system during initialization.

The IP Address, Port Number, Account ID, and Password must match the configuration of the remote system. Otherwise, attempts to establish an outbound session with the remote system fails.
