I have a .bat file with the below example contents that is run via Task Scheduler.
C:\Windows\SysWOW64\cscript.exe C:\script.vbs > output
How do I stop taskeng.exe from opening every time the task runs?
Task Scheduler Engine (taskeng.exe) is specifically made to handle the scheduling and execution of your tasks.

So it would be unwise to stop taskeng.exe from opening every time the task runs.

i currently try to make script that prevent user to mute volume using nircmd .
but the script is fine when i run manually but when i run using task scheduler but only 2 line of system sound script executed, i try to make 2 different script between system sound and application sound result still same only system sound script executed.
nircmd.exe setsysvolume 13104 -->Working on task scheduler and can manually run
nircmd.exe mutesysvolume 0-->Working on task scheduler and can manually run
nircmd.exe muteappvolume mstsc.exe 0 -->Not working on task scheduler and can manually run
nircmd.exe setappvolume mstsc.exe 13104 -->Not working on task scheduler and can manually run
I have a job scheduled to run at 9:30 every day using Windows task scheduler. The problem is after it runs, the command prompt stays open. Does anyone know how to get it to close?
The full text in the "Add arguments (optional):" field is:
C:\WinPython64bit\notebooks\TreasuryTest.py exit 0
I have searched all over, but most fixes are for use directly in the command prompt, and it seems to function differently from the task scheduler.
I have a very simple bat file which does a MysqlDump.
When I manually execute the bat file, it works. When I click "execute" in my scheduled taks, it works. But the scheduled task itself, doesn't run when it should run (timer expires).
I've setup a scheduled task to run every 5 minutes. In the scheduled taks manager I can see "next time to execute" "16:55". But when it is 16:55 the text updates to "next time to execute" "17:00". But in the "previous time executed" nothing changes. It still shows the time I manually have executed the task.
So, the weird thing is, when I click "execute" for the task, it runs. But when the time expires and it should run by itself, nothing happend.
I've enabled the history for the task. But even there nothing happens.
Can you help?
At my work we have a set up with the task scheduler periodically starting a java program to read mails.
the task is scheduled to run every minute and it calls a .bat file which starts the java program.
Now the problem.
Once in a month or so the jave.exe process doesn't end properly, so the next minute when it tries to run I get:
Task Scheduler failed to start "\XXX Jobs" task for user "NT AUTHORITY\System". Additional Data: Error Value: 2147750687.
And then I get that message every minute until I terminate the java.exe from the task manager.
Now my question, in task scheduler there are some options to choose.
Under settings there is "If the task is already running, then the following rule applies"
If I then choose "Stop the existing instance"
Will this stop the java.exe or just the task? Or is there a better way.
Some advice would be welcome.
At the end of your batch file kill the task.
taskkill /im java.exe
java.exe could be whatever process you are planning on killing. You can add multiple lines of tasskill in a batch file to kill multiple processes at a time.
taskkill /im java.exe
taskkill /im explorer.exe
taskkill /im svhost.exe
"Stop the existing instance" : The Task Scheduler service will stop
the instance of the task that is already running, and run the new
instance of the task.
that means it will kill the process that the scheduler has launched, cmd.exe in your case, as you told us your program is started from within a batch.
Now, i'm not familiar with java but i guess that stopping your batch will kill the java process that where launched if it is not started as a service.
The scheduler will then run another cmd process and execute your batch once again
Better solution would be fix the java hang. As the process starts every minute then in your java program should have the code to automatically exit if it takes more than a minute to complete the task. Another way would be in the batch file you can kill the process after 1 minute. Use the taskkill /im to kill the process.
I am working with Windows 7 and I have an application that returns zero (0x0) when successful and one (0x1) on error situations.
I have scheduled this app using Windows Task Scheduler. I have checked the option boxes "If the task fails, restart every" and "Attempt to restart up to:".
I thought that a non-zero return code from the app would be enough to trigger the task to be restarted after the given interval. But nothing happens.
Any ideas what could be the issue? I tried to google it but did not found anything relevant.
Create a new task and set the custom event query like this:
<QueryList>
<Query Id="0" Path="Microsoft-Windows-TaskScheduler/Operational">
<Select Path="Microsoft-Windows-TaskScheduler/Operational">*[System[EventID=201]] and *[EventData[Data[#Name='ResultCode']!='0']] and *[EventData[Data[#Name='TaskName']='\YOUR TASK NAME HERE']]</Select>
</Query>
</QueryList>
Set the trigger advanced settings to Delay the task for a period of time like 15 minutes.
Configure the action of the new task to start a program:
Program/script:
schtasks
Add arguments:
/Run /TN "\YOUR TASK NAME HERE"
This will schedule the original task to run again 15 minutes after a non-zero result code is logged in the event.
I've experienced the same problem on a Windows 2008 server Windows Task Scheduler.
The action return a non zero code but the scheduler consider the task completed:
Task Scheduler successfully completed task "\SET Tasks\Scheduled task [Backup SET Server]" , instance "{...}" , action "C:\Windows\SYSTEM32\cmd.exe" with return code 1.
I've found on the web only one answer:
The Windows Task Scheduler does not
examine the exit code or any other
values when your task completes. You
must handle any error processing
within your own script or program.
...in this document: www.onlinetoolworks.com/docs/winTaskSched.doc
So I think now that the only way to workaround this problem may be to use task triggering on event. I'm investigating.
Regards,
Olivier.
You can,
activate history for Schedule (if not already)
on a History "Action completed" right click "Attached Task to This Event..."
Set a custom filter like this:
*[System[(EventID=201)]] and *[EventData[Data[#Name='ResultCode']='1']]

Nobody has answered the title question though. It seems as though the task scheduler has no way to detect a failed task? Surely it must have something because it has an option to restart failed tasks!
The option "If the task fails, restart" is misleading, a failed task is when Task Scheduler is not able to run one of the action correctly, not when the script itself runs and return an error code.
A very clever workaround suggested here can be used instead of additional task querying for events:
The issue is the actions are only considered to fail if they cannot be started. This is pretty dumb, but the scheduler doesn't care about the results of the actions.
One workaround is to add an action at the end to run something like "ok.exe" and then have your other actions either create "ok.exe" (good result) or delete it. (bad result)
This way when the Task Scheduler goes to run the last action it will fail to start it (if you had removed it, because your previous action failed). This will cause the Task Scheduler to go ahead and Queue up your Task for a restart based on the restart settings on the Scheduled Task.
PS: To create a dummy ok.exe, I usually just copy c:\windows\system32\clip.exe c:\mytask\ok.exe
-- Tolga
So what is suggested is to create a final action for the task that will call a dummy .exe file. If the .exe file is not found, this will correctly cause the failure for the task and trigger the restart option. As .exe file he uses clip.exe from Windows system folder, this is nice I think because is very small and won't do any action if called on it's own.
Caution
I've tried with empty .cmd and .bat files but this will not trigger correctly the fail trigger. It must be a .exe file apparently.
Of course a mechanism to rename/move the ok.exe file in case your target script/job fails is needed.
I've pointed the Task Scheduler to use the wrapper script below with success. Edit the path to ok.exe as needed, I've copied it in the same directory as this wrapper script:
#echo off
:: This will reset the .exe name to make sure the .exe is available if error is
:: not triggered. See `:trigger_error`.
if exist ok.exe.nope (
rename ok.exe.nope ok.exe
)
:: This script is used as batch runner by Task Scheduler.
:: MAKE SURE THE SCRIPT WILL RETURN AN ERROR CODE !=0
echo Here is my script!
:: If script above exited with an error, rename the `ok.exe` file. This will
:: cause a failure for Task Scheduler following action attempting to run
:: `ok.exe`, thus triggering the restart conditions.
