Hey guys,

I have a quick question. (though I am using AIX, I think this can go under Linux discussion in general.)

We have this Unix Script which implements some business logic. It's usually being run under some IBM AIX scheduler (called Maestro).

Now, I performed an adhoc run of this script, through ./scriptname, now the script is currently running. The problem is, I forgot that this script is still scheduled in Maestro, so, I am expecting that this script will again be executed as scheduled. If that happens, I'm gonna have a hard time since the script implements some business logic that I can easily get into trouble with.

The script is STILL running, expected to run for a couple of more hours. So, what I did is to have a backup of the script, replace it with a dummy file that does nothing. These are all under the following assumptions:
1. I can replace the script with anything since the original script is already running in memory and would not be interrupted whatsoever.
2. The Maestro scheduler would be reading the dummy script (which does nothing) instead of the original script (which I placed somewhere in the filesystem)

I would like to confirm if these are correct? Though I've already done this, I just need somebody's confirmation so I can stay calm.

Cheers!

I'd double check with lsof and fuser; it the original file/inode is still open, you might be in trouble.
BTW, did you mv or cp the file?
It sounds like you did this after starting the run; correct?

Ultimately the safest thing would be to 'cancel' or 'suspend' the next run of this job from within Maestro. I assume it has a suspend / cancel option, a tool like that definitely should have.

I replace the original script through mv, and yep, I did this after the run.

Unluckily for me, I don't have access to Maestro

We'll see what happens. The scheduled run is about a minute ago

It worked

Maestro kicked off the dummy script.

Cheers!
