I have a problem with a old database program called Q&A (symantec). Since I transfered from Novell 3.12 to Windows NT 4.0 there are problems when 2 users write at the same time in the database. Q&A gives a write error and the database is corrupt. When this happened the index file of the database got 2 locks.

Can anyone tell me what locks are, and how I can solve this problem????????????

I don't know this program, but most database program that are ment for using by more than one person at a time use record locking. This means that a part of the database (record) wil be locked. This means that only one user can access the record that is locked, and the other users can't use the same record. This is done so that it's not posible for two user to change the record at the same time.

User "A" wan't to change record "100".
User "A" tryes to lock record "100".
If the locking went ok. User "A" is able to change the record.
  At this point, it not posible for user "B" to change record "100"
If user "A" is ready with the changing, the record will be unlocked.
  At this point, it's posible for user "B" to lock and change the record.

I know that a lot of database programs that work oke when placed on a Novell file server have problem's when they are being used on a Windows NT fileserver.
I advice you to put the database back on the Novell fileserver cause you probably can't get it work on Windows NT.

You probably know Exact software (it's the most used administrative software in the Netherlands). They have the same problem with locking when you databases are put on a Windows NT server, on a Novell server it's working ok.
