I'm using a medical records system built on an Oracle database. Our vendor just told us that we need to shut down Oracle's Enterprise Manager service when we're not using it, because it uses too much of the system's resources. I know I can get actual numbers by checking Sysinternals Process Explorer, but I was hoping that someone can give me info from their personal experience.
Do I need to shut down EM when I'm done with it, or is he being overly concerned?
We do the same thing on our testing and production servers too. I don't have any metrics to hand, but it did make a noticeable improvement in overall database response
