Best Linux I/O Scheduler(elevator) for Oracle database There is no single answer for this question but it is easy to answer it depends on your workload. If the interval parameter is specified without the count parameter, the mpstat command generates reports continuously. This prevents any one instance hogging all the server CPU, but if all instances are busy at the same time, the server can still get swamped. Q5.
