Oracle collects statistics for the activity of all latches and stores these in this view. Gets is. the number of successful willing to wait requests for a latch. Similarly, misses is how many times. Spingets number of times a latch is obtained after. Sleeps indicates how many times a willing to wait process slept. Waiterswoken. tells how often a sleeping process was disturbed. This view stores all information relating to locks in the database. The interesting columns in this. Important possible values of type are TM DML or Table Lock, TX Transaction, MR Media Recovery. ST Disk Space Transaction. Exactly one of the lmode, request pair is either 0 or 1 while the other indicates the. If. lmode is not 0 or 1, then the session has aquired the lock, while it waits to aquire the lock if request is. The possible values for lmode and request are. If the lock type is TM, the column id.
