How set timeout period in work flow manager?

Question

HI,
I am using File_Exists activity in process flows.
Its working fine.
But the problem is, if the file doesnot exist, then, I want to wait from some time, and if the file doesn't create within that time, then only, it should go for the next trasition based upon its status.
In my case, it is checking whether the file exists or not. If not, it is ending up with warinings, without waiting for certain amount of time.
Could any one help me, like how to solve this problem.
I heard that, we have to set the time out period.
Any suggestions are welcome.
Thank you,
Regards,
Gowtham Sen.

Gowtham,
There is no explicit "Timeout" function that you can set.
From the 10.2 Docs:
File Exists
Use the File Exists activity to verify the existence of a file before executing the next activity. In the Activities panel, type the name of the file.
The File Exists activity checks to see if the file exists only once. If the file exists, the process flow proceeds with the success transition. If the file does not exist, the process flow precedes with the warning transition. The File Exists activity triggers the error transition only in the case of a catastrophic failure such as TCL error when using OMB Plus.
The File Exists activity has one parameter called PATH. Specify either a fully qualified filename, directory name, or a semi-colon separated list for this parameter. The paths are normally tested in the same host that is running the Control Center service.
The security constraints of the underlying operating system may disallow access to one or more files, giving the impression that they do not exist. If all the paths exist, then the activity return EXISTS. If none of the paths exist, then it returns MISSING. If some paths exist, it returns SOME_EXIST.
So, if you are only re-checking once, then I would make a warning transition out of your file exists activity and feed it into a wait activity. This you could set for as long as you need. Then transition to another File Exists activity for the second check. The transition out from this one can then pass on the status to the rest of your process flow.
If you want to do a few waits, you would need to embed this process into something like a While Loop that you can escape by using a counter that you increment via an Assign activity after each check. When your file exists is successfull you can Assign a proper exit value to escape the loop.
