7.141 V$CON_SYSTEM_EVENT
V$CON_SYSTEM_EVENT
displays information on total waits for an event in a container.
Note that the TIME_WAITED
and AVERAGE_WAIT
columns will contain a value of zero on those platforms that do not support a fast timing mechanism. If you are running on one of these platforms and you want this column to reflect true wait times, then you must set TIMED_STATISTICS
to TRUE
in the parameter file; doing this will have a small negative effect on system performance.
