Step 2—A User Requests Access to a File Pool in Another TSAF Collection

The user TONY enters a CMS ACCESS command for his top directory, that is maintained in the file pool POOL15. In the TONY virtual machine, CMS tries to connect to the resource POOL15. The symbolic destination name is resolved into a request to connect to POOL15 in remote LU POOLACC through gateway POOLGAT. AVSa translates the request and sends it to VTAMa. VTAMa sends the request to the SNA network.

In Collection B, a connection request comes in through POOLACC (a global gateway) from the network and AVSb translates the request. The user ID and password (TONY and PASSB) are validated in Collection B. CP then routes the connection to POOLSRV. The user ID TONY is presented to POOLSRV for authorization to access POOL15. Because TONY is an authorized user, TONY is connected to file pool POOL15 (see Figure 1).
