2 Confusing to Oracle DBAs, the Linux sar facility is contained in the sysstat package. On Linux, this package is not automatically installed, but obviously can be very helpful for our purposes.

3 Obviously, there is a lot more you can do with the /proc file system than I have presented here. My intent is to expose you to the capability and provide a simple example of its usage. Plenty of online information about this file system is available.

4 At the time of this writing, Oracle does not show the run queue length in v$osstat. I suspect this will change, as the information is easily available from the /proc file system.
