set process/suspend

I have batch jobs that run for several days, and occasionally I need to reboot, which kills all batch jobs of course.
If I /suspend the batch process before rebooting, can I /resume it after the reboot and have it run like nothing happened?
I assume /suspend /resume works fine on a running system; has anyone tried it with a reboot in the middle?

Re: set process/suspend

It will only 'block' the process and prevent any further execution. Unfortunately, on a system shutdown ALL processes are deleted. Last time I checked, OpenVMS cannot preserve a process state that survives a reboot.

You can check the batch "restart" feature, but that is only helpful if you have multiple .EXE files with some DCL code in-between, because the batch "checkpoints" are DCL labels. You still need to cope with the deletion of processes and data inconsistencies due to the deletion.

JKrucus,

"I have batch jobs that run for several DAHS" (capitals by me)

and

"occasionally I need to reboot, which kills all batch jobs of course."

It strikes me as strange that you have to reboot VMS DURING a run of ony a few DAYS.

Are you sure you NEED that frequent reboots?

VMS systems routinely run uninterupted for months or years.

I would have a serious review of the NEED for those reboots.

Proost.

Have one on me.

oops.

"DAHS" should read "DAYS"

Re: set process/suspend

It is an application issue, not a VMS issue, that requires a reboot, but that is another story.....

Re: set process/suspend

Still you should be able to kill the application without having to reboot through Availability Manager if no other way.

Re: set process/suspend

Re-read the thread: it's not about killing a process!
It's about preserving a process state over reboots.
