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.
