Lock Consoles to a Specific Environment

In most cases, the pool of JES consoles can be shared by any number of users on a temporary basis.

However, there are cases where a specific environment must not miss out on obtaining a console, for example, if the pool of consoles is temporarily exhausted, or the consoles are timed out and are unable to be reassigned.

Note: We recommend that you avoid using JES consoles and use Extended MCS consoles (XMCS) instead.

To lock consoles to an environment, use the SYSCMD OPT=LOCK command.

Important! If you use SYSCMD OPT=LOCK from an NCL procedure and the procedure needs to issue an &INTCLEAR, then make sure you use &INTCLEAR TYPE=ANY rather than &INTCLEAR TYPE=ALL. &INTCLEAR TYPE=ALL will release the locked console.
