My First Experience Running SLOB – Don’t Repeat My Errors (AWR)

If you are wondering what I have been busying myself with, this post explains it. As you may have noticed, I am still testing one of the Oracle systems using the SLOB framework and learning on my way. I ran several tests with the same parameters (Readers 24) and noticed that for one reason or another awr.txt reports different runtimes.

My First Experience Running SLOB – Status Update 2 (first results)

I think the results we got so far may surprise you. At lease they don’t seem to be the results +Alex Gorbachev and +Kevin Closson expected to see. You can find the first related blog post here. It will give you the necessary context for further reading. Just to recap: +Kevin Closson says that “Orion may give It’s VERY easy to get huge Orion nums but reasonable SLOB” and +Alex Gorbachev says that “lots of the system IO bound below the CPU level so you should see similar number with Orion or SLOB”. Let’s see what the first results revealed.

Oracle VM: What If You Have Only 1 HDD System?

In my previous post, I described how to install Oracle VM and Oracle VM Manager on the same sandbox.

If you have just one HDD in your system, then you are in trouble since part of it is already occupied by the Dom0 host.
