If all you want is counts, you can enable collection of file statistics using FILE.USAGE.CLEAR command. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
[U2] UV - Tracking file writes
I need to track all processes that write to a specific file. At one time I remember that you could set some type of trigger to do this. If someone could provided me the information on how to do this, or direct me to the documentation that covers this I would appreciate it.

RE: [U2] UV - Tracking file writes
A trigger would be an ideal method as it's non-intrusive to your existing code. There are some caveats though. Basically you'd create a UNIBASIC program that could have any logic you want. In your case, probably something that writes to an audit file. You then attach this program to your file via a CREATE.TRIGGER command most likely defining it as an UPDATE trigger (there are some rules and parameters that you can get from the docs). Since your goal is to identify processes, the caveat would be how to identify the process. The trigger is based strictly on the file and doesn't really care what process initiated it. Depending on your platform and how your system is put together, @VERB or @SENTENCE might give you what you need or you might have to come up with something different.

Re: [U2] UV - Tracking file writes
I use file triggers quite frequently to trace down problems with processes. You can find the documentation for this in the Universe SQL Reference manual.

RE: [U2] UV - Tracking file writes
The UV SQL Reference manual gives a pretty good description. The odd part is cataloging the trigger program; if you're pick flavor, you'll need to create an information flavor CATALOG verb (although I don't remember if I was working on a Windows or Unix box?). Also, before the Trigger subroutine can Write to a file, it must first READU the record. And I think you need to be on UV 10.x to use triggers with files.
