Initialization Parameters, 181 of 188

TIMED_OS_STATISTICS

Parameter type:	Integer
Parameter class:	Dynamic. Scope = `ALTER` `SYSTEM.`
Default value:	0
Range of values:	Unlimited
`TIMED_OS_STATISTICS` specifies the interval (in seconds) at which Oracle collects operating system (OS) statistics when a request is made from the client to the server or a request completes.
On dedicated servers, Oracle collects OS statistics at user logon and after each subsequent client invocation through the OCI into the Oracle server as a remote procedure call message. On multi-threaded servers, Oracle collects statistics when client calls to Oracle are processed. A value of zero specifies that OS statistics are not gathered. To collect statistics, set a value meaningful for your application and site needs.
Note: Gathering OS statistics is very expensive. Oracle Corporation 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.
