The SQL statement that waits for lock release

Blocked SQL Hash

The hash value of the statement waiting for lock

Blocking Serial

Serial number of the locking session

Blocking SID

A SID that holds locks

Client Machine

The name of the computer where the client is running

Cross Instance

Indicates whether the global lock and the locking and blocked sessions are running on different RAC nodes (True) or not (False)

DB User Name

The Oracle database account of the started session

Host

The name of the host where the instance is installed

Instance

Instance name of the session in the lock tree

Lock Duration

The number of seconds the lock is running

Lock Event

The wait event on which the blocked statement is waiting

Lock Mode

The lock mode in which the session holds the lock.

The lock mode can have one of the following values:

Lock Request Mode

The lock mode in which the process requests the lock.

The lock request mode has the same possible values as the lock mode.

Lock Type
