batch file got stuck while running qlikview documents

[jeevays7]

Hi all,

I have Five qlikview documents and I am running those application using batch file.

Some times, after the 4th application run successfully, the next application is not initiated to run.

the batch file got stuck(showing the 4th application in comment prompt) in the 4th application only. it does not initiate 5th application.

the log file of the 4th application also has no Errors.

What s the problem? how can i identify the problem?

It used to work fine and now the issue started or it never goes to 5th file?

can you post the code?

Hi,

Sorry, i cant able to paste the code. it is a big application. Can you suggest what is the problem might be?

I think the variety of what could be going temporary wrong is quite big but I assume that it's caused by some kind of conflicting between this process and another processes.

For example that any other process tried to access any used file/folder which are read, used or stored at this moment - this could be other users or tasks or any security routine or any OS process like windows shadow copies and so on.

Batch-routins are usually not very robust against any kind of disturbances and fail therefore easily. You could try to find any hint within the various windows log-files, especially the event-log but if you don't find there a clue you would need to go further with a process-monitoring which isn't really trivial.

Even if you find the cause it doesn't meant that you could just fix and/or bypass it - it could be also possible that you need a different approach to execute your tasks maybe by implementing some more or less expensive error-routines and/or even a second tasks-line which checks the first and restarted them if they failed.

did you try to execute your 4 application manually???

You are not getting any error in error log because that application is not yet closed. It is still open in backend.

Modify your batch script as below.

"C:\Program Files\QlikView\Qv.exe" /nosecurity /r Your qvw application path

IF %ERRORLEVEL% NEQ 0 (

  exit /b 1

)

and In application set errormode=0;

So that if there is any error in you application batch will close that application and run next application.

Whenever you think batch file stuck then open task manager and check that which file open in back end??

[jeevays7]

Yes, You are correct. There is no error is log file, then why it is still open in back end?

I don't have any error, then why i have to do the above script in batch file .?
