This means that someone else has a lock on the row that you are trying to lock.

Speak to your DBA and they can assist you with seeing what other sessions are locking that row, by looking at V$LOCK.

Or search this site for V$LOCK for some sample queries.

Oracle Forms locks the row the user is editing. It's a row level lock with no wait. So two users can't work on same row.First one got the row will lock it and second user or users have to wait for the lock to be released by the first user. Hope this helps

Oracle does the locking internally when you access a row thru forms. It's internal to oracle. You don't need to lock it explicitly.
