This posts finalizes a few weeks of work on comparing SLOB and ORION IO testing tools.Read More >
In this blog post, I will share the physical IO testing results I got by running SLOB and ORION on the same system and on the same disks. I will use those results as a reference in a few blog posts to come. As of now, I would like to make few points based in the results here.Read More >
As heralded by Iggy Fernandez and Gwen Shapira, NoCOUG has launched its Third International SQL vs. NoSQL Challenge. Pythian is sponsoring the challenge, so I decided not to take part in the contest. However, I’m still having a crack at the problem just for fun. Here is my first take on it.Read More >

But as a follow up, I decided to search though Google and MOS in order to see if there has been any good development in resolving the issue from others.Read More >

As SLOB takes the IO testing on Oracle Instance level, you need to watch for several things before you declare official testing results. My suggestion is: Don’t take any result for granted. You need to assess those before stating that you are done.Read More >
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.
I was wondering why I was getting inconsistent runtimes for similar conditions. The answer to the mystery was very simple: The runit.sh script just generates awr.txt reports for the last and before last awr snapshots.
