A service is a name associated with some component of work. That component of work might 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 process called 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 process would be referred to as a call to a “black box.”

In a CICS application that uses TMA TCP for CICS, a service name is passed in the data area in an EXEC CICS LINK command and the results are returned in that same area. The service screens use the terms “service name” and “remote service name.” The 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, but if naming conventions differ, you can use different names.
