tWaitForFile : always wait 1 minute

jmd — Wed, 20 Mar 2013 14:48:26 GMT

Hi,
I set the time between iterations to 1 (second)
and I tried "when a file is created" or "when a file is updated" as the trigger
But the component (in command line execution) always wait 1 minute, even if the file is there before 1 minute
What's wrong ?
I'm in version 5.2.0

Hi,
If you execute your job in studio, Is it still last for 1 minute, too?
Here is the component reference tWaitForFile with scenario

No, in studio, the component doesn't wait 1 minute
I already had a look at the standard scenario in documentation : this one tals about file deletion trigger which is not my case

Looks like this is the problem - there is an option in Advanced settings of the component "Wait for file to be released"
Hope this helps

I don't think something wrong with your job, because in studio everything work well, right? I suppose the problem in your command line, could you give us more info about that?(By the way, the standard scenario in documentation is to help you understand this component quickly)

There isn't any problem in command line : it's the standard command line generated by Talend

Hi,
Well, could you post the screenshots of your work flow so that we can know your job more clearly. It may be blocked on some segment. In addition, you should know that Studio and Command line are transmitting over the network, so there is no absolute synchronization.

Hi jmd,
One more question about your job how do you know it is a minute delay? How do you calculate it ?
Best regards

Sorry, it's 2 minutes (120 seconds), not 1
120 iterations and 1 second between iterations
But 1 or 2 minutes, this is the same problem : it works in studio and not in command line

Hi,

120 iterations and 1 second between iterations

Do you mean one of your iteration last for 120 seconds? How did you calculate it? I mean use what? a counter? Or you found there are 120 iterations in your job run time for 120 seconds? If so, that means time between iteration is "1" second, it isn't right?
Best regards

Did you have look at my screen captures ?
It shows precisely the configuration of the component :
1 second between iterations
max iterations : 120
You don't need a counter !
And concretely, when it executes, it waits the max time before exiting the component, while a file is present since many seconds

So, nobody has an idea ?
Nobody has encountered such a problem ?
The files to wait for are on a network drive, with a UNC path ( \\edi_server\path_to_folder\ )
