In AutoSys, we can put machines OFFLINE using sendevent:
sendevent -E MACH_OFFLINE -n machine
Is there an equivalent in UUJMA ?
In order to temporarily stop execution, you can either
1) remove agent name from your job definition on the scheduler side,
2) or stop agent on UUJMA agent box.
NB Only UUJMA,as an agent is supported at the moment. There is no support for JMO scheduler or manager.
