If you have a file that is a set size and is constantly open, how can I tell its being used?
I have a db (flat file) that when a piece of code got itself into what I believe was an infinite loop (timing issue) there wasn't any updates to the database for an extended period. I need to know if there is something I can do to monitor and determine if this is happening. I can't think of a way to determine if its being written too, as the size is constant and it doesn't open or close on a regular intervals (changing the file timestamp). Is there anything I can do on the O/S side of things to determine this?
Much appreciated if anyone can point me in the right VMS direction, other than re-coding the actual application that uses the flat file.
