TIMED_OS_STATISTICS

Property Description
Parameter type Integer
Default value If STATISTICS_LEVEL is set to ALL, then 5

If STATISTICS_LEVEL is set to BASIC or TYPICAL, then 0

Modifiable ALTER SESSION, ALTER SYSTEM
Range of values Unlimited

TIMED_OS_STATISTICS specifies (in seconds) the interval at which Oracle collects operating system statistics when a request is made from the client to the server or when a request completes.

A value of zero specifies that operating system statistics are not gathered. To collect statistics, set a value meaningful for your application and site needs.

Note:

Gathering operating system statistics is very expensive. Oracle recommends that you set this parameter in an ALTER SYSTEM statement rather than in the initialization parameter file, and that you reset the value to zero as soon as the needed statistics have been gathered.
