in reply to cgi wrapper??

Since I brought up the scheduler in the previous thread, I'll defend my choice ;-)

Scheduler is built into NT/W2K/XP/2002/yadayadayada). So no need to install it.

Win32::AdminMisc::ScheduleAdd( $Machine, $Time, $DOM, $DOW, $Flags, $Command )
will schedule $Command to run on the computer $Machine at $Time on the day of the month determined by the bitmask $DOM and the day of the week determined by the bitmask DOW.

So, you loop through your list of servers, executing the function with each iteration. What's so tedious about that?

    Note: To add things to the AT scheduler on a windows machine, you don't actually need a module. You can do this via command line from a remote PC using at \\computername. See AT /? for further info.


      Right, but at is very cumbersome and it's much more easier to use Win32::AdminMisc for this - i.e. if you want to add a scheduled task but don't want to add it if it's already there, then you have to parse the output of "at" - This could be tricky and requires an extra system call for each addition. It's much easier to use the ScheduleList() method and then use ScheduleAdd() if you need to.

      If it's well written and easy to use, I prefer to use a module than a system call.

    Excellent, I forgot that you can specify a remote machine for ScheduleAdd(). That would be the best way to do it, unless it's something that has to be executed on demand.

    Do the targer machines have to have AdminMisc module installed or just the machine running the script?
      Just the machine running the script needs to have AdminMisc installed. The target machines need to have the scheduler/mstask service running.
        A couple of other things worth thinking about with Scheduler is permissions:

        1. It could get tricky if the target machines are on different domains\workgroups.
        2. Remember that by default Scheduler service runs under the Local Sytem account.
        If the target machines are on different domains\workgroups you may not be able to use ScheduleAdd() remotely. You could try Win32::AdminMisc::LogonAsUser() but I am not sure how that works. In a worst case scenario, you may need to run the script once under the admin account for each domain\workgroup.

        Although these points probably aren't relevant to this question, I recommend setting up a seperate account for the scheduler service and only give it the permissions that your scheduled tasks need rather than all those that LocalSystem has by default.
