Wait Event – library cache load lock

The session tries to find the load lock for the database object so that it can load the object. The load lock is always obtained in Exclusive mode, so that no other process can load the same object. If the load lock is busy the session will wait on this event until the lock becomes available.

Wait Time: 3 seconds (1 second for PMON)

 

Parameter Description
object address Address of the object being loaded
lock address Address of load lock being used
mask Indicates which data pieces of the object that must loaded
