Hi Terry, Congrats on winning the appeal and on passing too
Can you answer us a couple of questions please.
1. Can you give us an overview of your locking mechanism?
2. Did you deal client crashing?
3. Did you implement safe server shutdown?
Any comments would be greatly appreciated. Thanks.

Thanks Satish and everyone.
Locking - Mine was pretty basic, modeled after Max's book, no fancy lock manager or anything like that. I used the lock mechanism for the logical record locking and synchronization where appropriate for physical record locking. Of course, I lost a big chunk of points for locking and got the famous 44 score.
Client Crashing - I did not deal with it. Clients in my app don't explicitly call the lock methods (thin client, with locking done server side via business methods in Data class).
Safe server shutdown - I had a very simple server gui to kick off the server and it also provided a shutdown button. Shutdown closed the appropriate database file and removed the binding, but did not notify clients or do anything fancy. To change properties, you shutdown the whole thing and start it up again. I did not use that shutdown hook approach that has been mentioned out here before.
I really focused on keeping my assignment simple (the KISS method). However, that almost killed me with the 48 hour rule as some of the SCJD'ers know from my detailed postings out on the forum.
Good luck!
TJ
