However, I wanted to ask what you think about the following: wouldn't it be simpler to place locks on 5 (or 10 - depending on the number of licenses) consecutive records in a table, instead of creating files with LLFF and seeing whether they can be opened? Or would record locking be less safe, for some reason?

Walter, thanks for your reply.

Now, Sergey thinks that if the application hangs, the record lock might stay in effect for a long time. What is your opinion / experience on this?
