Question:
How do you disable the terminal lock due to inactivity?
Answer:
Set LOCKTIME(0) for the FACILITY via CA Top Secret Parameter File or TSS MODFIY FAC(facilityname(LOCKTIME(0)).
TSS MODIFY commands are temporary changes and will be reset if TSS is recycled or z/OS IPLed.
Set LOCKTIME in the CA Top Secret Parameter File to make the change permanent.
