Background:

I’ve a folder that gets pumped with files continuously. My SSIS package needs to process the files and delete them. The SSIS package is scheduled to run once every minute. I’m picking up the files in ascending order of file creation time. I’m building an array of files and then processing-deleting them one at a time.

Problem:

If an instance of my package takes longer than one minute to run, the next instance of the SSIS package will pick up some of the files the previous instance has in its buffer. By the time the second instance of teh package gets around to processing a file, it may already have been deleted by the first instance, creating an exception condition.

I was wondering whether there was a way to avoid the exception condition.

Thanks.

    How are you scheduling the job? If you are using the SQL Server Job Scheduler I’m under the impression is should not re-run a job already running; see this SO question: Will a SQL Server Job skip a scheduled run if it is already running?

    Alternatively, rather than trying to move the file around you could build a step of your job to test if it is already running. I’ve not done this myself but it would appear to be possible, have a read of this article Detecting The State of a SQL Server Agent Job
