What is a deadlock ? Explain ...

Answer / sawant

Two processes wating to update the rows of a table which
are locked by the other process then deadlock arises.

In a database environment this will often happen because
of not issuing proper row lock commands. Poor design of
front-end application may cause this situation and the
performance of server will reduce drastically.

These locks will be released automatically when a
commit/rollback operation performed or any one of this
processes being killed externally.
