Figure 1-2 Oracle TMA Client Gateway Configuration

Figure 1-2 shows 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.
