One day I came up with the following neat idea. Start a second listener, on a different port, calling it the emergency listener. Then renice the listener process with higher priority. Now, every time I connect to the database via my emergency listener, my connection gets higher priority, and thus feels like there’s no problem with the database’s resource use.
There is one little caveat however. You need to either have access to root, or have a nice SA that will add renice to your sudoers file .

Indeed, while the technique we discuss here is basic, it gives a good overview and is very easy to use. So let get focused… We will use iostat utility. There is much to say about IO monitoring and interpreting results. Perhaps this is only the first of a series of posts about IO statistics. At Pythian we often come across different environments with specific characteristics and various requirements that our clients have. So stay tune — more to come.
