A service is a name associated with some component of work. That component of work can be a banking transaction, an airline flight reservation, or an order for a dozen widgets. In Oracle Tuxedo, a client program that needs work done makes a service request. A server performs the work described in the service request on behalf of the client, then returns the results of its efforts back to the client. In MVS this would be referred to as a call to a “black box.”

The service screens use the terms LOCAL SERVICE NAME and REMOTE SERVICE NAME. The LOCAL SERVICE NAME (such as, CIC01XXYYZZ) is what the service is known as to your CICS environment and the REMOTE SERVICE NAME (such as, WITHDRAWL) is what the service is known as to Oracle Tuxedo. For simplicity, you can make both names the same; however, different names can be used. Changes to the inbound service file are only picked up when the Handler is restarted.
