Wait Events - DFS lock handle

DFS lock handle

The session waits for the lock handle of a global lock request. The lock handle identifies a global lock. With this lock handle, other operations can be performed on this global lock (to identify the global lock in future operations such as conversions or release). The global lock is maintained by the DLM. Wait Time:

The session waits in a loop until it has obtained the lock handle from the DLM. Inside the loop there is a wait of 0.5 seconds.

The session needs to get the lock handle.

Oracle is waiting for the lock handle. The lock handle identifies a lock that is currently held. This lock handle is obtained from the lock state on the initial acquisition and may be used to reconstruct the state for conversion or release. This event is called if we are getting a lock and we want to know the lock handle (to identify the lock in future operations like conversions or release). The lock is maintained by the DLM.
