OPT—Optimize Data Streams
If optimization has been turned off, use the OPT command to resume optimizing data streams for included applications.
To turn optimization on or off, enter the operator command from the MVS console in the format subsysid OPT | NOOPT. subsysid is the name of the ULTRAOPT subsystem that was established when ULTRAOPT was installed. The NOOPT command has the same effect as the NOOPT startup parameter.
