The automatic terminal locking feature is available for TSO. Locking is enforced whenever a command (not subcommand) is about to be executed. If the amount of time since the last command execution exceeds the LTIME threshold for the user or the LOCKTIME of the facility, the terminal becomes locked.
CA Top Secret sees the time difference between command executions only. It does not see keystrokes or recognize when a user presses the Enter key. This is important for users who spend long periods of time in EDIT or SPF/EDIT. Use the timeout feature of your session manager if the LOCKTIME feature in the TSO does not meet you needs.
If a user has been in EDIT or SPF/EDIT, his terminal may lock when he ends the edit session. If this occurs, the user must enter the TSS UNLOCK command by switching to menu 6, or under TSO/E, on the menu command line.
Note: When TOP SECRET locks the terminal, TSO responds with a S806 abend.
A locked terminal can be logged off. Also, terminal locking does not interfere with the MVS timeout feature (S522 abend).
