Security Checking from Mainframe to UNIX

Figure 3-2 depicts the process flow for security verifications from a mainframe to TMA TCP

1. The user ID, established at mainframe log in, is checked by system security to verify that the

user has permission to start a client transaction.

2. The user ID is checked by system security to verify that the user has permission to send a

request to the gateway.

3. With each request, the gateway passes the user ID to the Tuxedo gateway.

Note: To pass authority checking, the user’s Tuxedo identity must match the mainframe

user ID exactly.
