TIMED_STATISTICS
specifies whether or not statistics related to time are collected.
Values:
true
The statistics are collected and stored in trace files or displayed in the V$SESSTATS
and V$SYSSTATS
dynamic performance views.
false
The value of all time-related statistics is set to zero. This setting lets Oracle avoid the overhead of requesting the time from the operating system. Normally, TIMED_STATISTICS
should be false
.
On some systems with very fast timer access, Oracle might enable timing even if this parameter is set to false
. On these systems, setting the parameter to true
can sometimes produce more accurate statistics for long-running operations.
