I have found myself in need of a script being run once every few minutes, on an ongoing basis, for as long as the server is running.
Basically, I want to check for the existence of a file, for example, once every 2 or 3 minutes, round the clock. Now, I have all the code put together, and COULD do it with a set of scripts and the task scheduler, but... that just seems really kludgy to me.
What I want to ask is... when you guys/gals get into a situation where you need to have some script or command run over and over every few minutes, what do you use? A set of scripts? A third-party app?
Thanks,
DS

Ne'ermind, I'm writing a mini-app that will be run as a service and will do this for me. Of course, I am using vb 2005 express, so who knows how "mini" this thing will be. <sigh>

Thanks. The existance of a file was just an example of a task to perform. I am actually using WMI to monitor the status of the UPS attached to the server. In the event of a On Battery event, if it lasts longer than 2 minutes, I will hibernate all the machines on the network, stop the exchange, blackberry, and SQL services, and hibernate the servers.

Why can't you run the script forever with a 2~3 minutes sleep in a loop?

Because I won't have any way of knowing if the script has crashed or is still working. by starting a new script, I am basically starting with a clean slate and can chekc for status.

I don't want to see the result. The results would be pretty obvious - the lights in the building are all out, and UPS's are beeping like crazy. lol
After much battle with Vb.express.2005.crapola, I decided to kludge it and go with task scheduler. *sigh*
Here's the logic flow, as it stands right now.
Once a minute, kicks off a script (named appropriately enough, KickOff.vbs) that:
1> Check for power.out file.
1a> If file eixsts, exit.
1b> If file does not exist, continue
2> Check for process named cs_service.exe
2a> if process exists, kill it.
3> Spawn CheckUPS.vbs script using a copy of cscript.exe named cs_service.exe
4> Exit
CheckUPS.vbs
1> Check UPS status via WMI
1a> if On A/C power, exit
1b> If on Battery power, continue
2> Create a file named power.out
3> Begin a counter, C1
4> In a Do...Loop, check the UPS staus.
4a> if on A/C power, exit
4b> if still on battery, continue
5> For every second that the UPS is on battery, increment the C1 counter.
6> if C1 = 120, spawn Power_Down.vbs
7. Exit
Power_Down.vbs
1> Get a list of workstations currently online on the network
2> Send a hibernate command to each of these.
3> After they are hibernated, stop the exchange and blackberry services on the exchange server
4> hibernate the exchange server
5> Stop the SQl service on the local server
6> Set a flag int he registry that the server hibernated after 2 minutes battery time.
7> hibernate the local server
Changes to the above will be:
a) Instead of a power.out file, will use a flag in the registry.
b) Will Clear the flags upon first run after a hibernate
i have 99% of the code written, and tested in sections. I am now trying to find the time to test the whole thing and portablize (is that a word?) the code so that it will run on various networks/servers, and not just mine. Once done, will post int he post yer code section.
Thanks for the tips, folks.
