Hi javafun,
Welcome to JavaRanch.
We don't have many rules here, but one we do have is the JavaRanch
Official Policy On Displayed Names, which requires your displayed name to be a real name.
Could you please change your displayed name to meet this policy? You can change it
here.
I don't think you misunderstood that part of the problem. In standalone mode, only
one client should be connecting to the database. There should be no need for file level locking.
It sounds like the problem is elsewhere in your locking solution.
Regards, Andrew
