"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That occurs when two or more tasks (one could be yours, and another task someone else is running) are waiting on the same area of data, even if it's in memory. Many times this happens because the query may be going across an entire table, perhaps updating many rows, and someone else's query is waiting on it to release that segment of data.

In SQL Server they are called deadlocks.

to keep it very simple --> set of bytes in your data files of the database - referrred to as a block in oracle database.  One or more database sessions/processess trying/waiting to read/write to the same block will cause contention.
