The aim of this document is to show how to use a "Deadlock Graph" produced by and ORA-00060 error to identify the base problem. This article presents examples of each type so that investigation and resolution can continue along the right track. By examination of numerous Service Requests, we have seen that the most common types of deadlock can be identified by a "signature" deadlock graph that can be used to identify the "type" of deadlock being encountered. When such a deadlock is detected a trace file is produced containing a "Deadlock Graph" (along with other useful information). If you repeat the last (cancelled) operation in the session, then you will get the deadlock again. The session that detected the deadlock is still 'alive' and the rest of the transaction is still active.

When Oracle detects a deadlock, the current SQL in the session detecting the deadlock is cancelled and 'statement-level rollback' is performed so as to free up resources and not block all activity.
