Re: Locks / Latches ??

I believe there are 8 different types of locks. Most prevalent are the exclusive locks(noone can touch this record, but you) and row share lock(I cant remember the rules on this one).

go to otn.oracle.com look in documentation, 9i database. Concepts. There is a section on locking.

You can release locks by issuing commit,rollback, or killing a session.

You have no control over latches directly. The type of action you take determines whether you aquire a latch.
