Figure 1-2shows the configuration of the Oracle TMA client gateway. A client program (your CICS program) issues an EXEC CICS LINK command to the Pre-requester. The Pre-requester verifies that the service name is valid and identifies the Requester to which it should it should pass the request. The Pre-requester starts a different Requester for each configured remote endpoint. The Requester then sends the request to the remote Oracle Tuxedo domain and waits for a response. Once the response is returned, the Requester notifies the Pre-requester and hands the response to the Pre-requester, which then returns the response to the client program.
