5.1 Testing Connectivity with Remote Systems
When you start TMA TCP for IMS for the first time, you should do so in a controlled environment, using a small, simple configuration that allows you to methodically test the system to verify your installation and the configuration.
An appropriate test configuration would include the IMS gateway
(one port) and one remote gateway. The SOURCE
distribution library includes several sample IMS client and server
transactions that can be used to test connectivity with a remote
Oracle Tuxedo Mainframe Adapter gateway.
By specifying a minimum number (greater than 0) of outbound sessions for a remote gateway, you can cause outbound sessions to be automatically established with that gateway during Error and Informational Messages. This can help verify outbound connectivity without having to make use of test transactions.
Execute test client and server transactions from both sides of the configuration to verify bidirectional connectivity. If errors are encountered, use the diagnostic messages issued by both sides of the configuration (that is, the IMS gateway and the remote Oracle Tuxedo gateway) to identify and correct the problem.
For a description of the TMA TCP for IMS error messages, refer to the Error and Informational Messages.
