In Part One, we discussed some of the more well known startup parameters. In today’s blog post, we’ll dig into parameters that are often used incorrectly or simply forgotten.

Every experienced IT person knows that bad things tend to happen on Fridays, and Friday evening is when we got alerted: major performance problems on the primary database server at one of our Enterprise clients.
