V$CON_SYSTEM_WAIT_CLASS

V$CON_SYSTEM_WAIT_CLASS displays the time totals for each registered wait class in a container.

Column Datatype Description
WAIT_CLASS_ID NUMBER Identifier of the wait class
WAIT_CLASS# NUMBER Number of the wait class
WAIT_CLASS VARCHAR2(64) Name of the wait class
TOTAL_WAITS NUMBER Total number of waits from this wait class
TIME_WAITED NUMBER Total amount of time spent in waits from this wait class (in hundredths of a second)
TIME_WAITED_MICRO NUMBER Total amount of time spent in waits from this wait class (in microseconds)
CPU NUMBER Total amount of CPU time consumed while implementing waits from this wait class (in microseconds)
TOTAL_WAITS_FG NUMBER Total number of waits from this wait class, from foreground sessions
TIME_WAITED_FG NUMBER Total amount of time spent in waits from this wait class, from foreground sessions (in hundredths of a second)
TIME_WAITED_MICRO_FG NUMBER Total amount of time spent in waits from this wait class, from foreground sessions (in microseconds)
CPU_FG NUMBER Total amount of CPU time consumed while implementing waits from this wait class, from foreground sessions (in microseconds)
CON_ID NUMBER

When queried from a non-CDB, time totals for each registered wait class in that instance are returned, and the CON_ID value is 0.

When queried from the root of a CDB, time totals for each registered wait class in every container is returned, and the CON_ID value indicates the container to which the time total belong.

When queried from a PDB, time totals for each registered wait class in that PDB are returned, and the CON_ID value is the container ID for that PDB.
