In this blog post I share physical IO testing results I got running SLOB and ORION on the same system on the same disks. I will use those results as a reference in few next blog posts. As of now I would like to make few points based in the results here.
The purpose of this blog post is to share my favorite speakers list from Collaborate 12 and give you hints on who you may want to listen at future conferences. Let me start with 4 speakers that I didn’t hear before Collaborate 12.
I just installed 3.1.1 Oracle VM server for training purposes on my sandbox and faced the same issue I faced installing 3.0.3 and 3.0.1 versions before. I quickly found a workaround that worked for me. But as 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 (Oracle may be ;). Anyway this is that I found.
The purpose of this blog isn’t to show off the results of my presentation at Collaborate conference, but to inspire you (and maybe myself in the future) and give you additional motivation to never give up on reaching your dreams if you truly believe in them.
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 results for granted. You need to assess those before stating you are done. Here goes my list.
f you are wondering what I am busy with then this post explains it. As you may 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 I noticed that for one reason or another awr.txt reports different runtimes. The answer to the mystery was very simple. The runit.sh script just generates awr.txt report for last and one before last awr snapshots.
After completing your Oracle VM and Oracle VM Manager installation (see my previous blog posts here) you are ready to start your friendship with Oracle VM technology. However to make your life and experience even more enjoyable I would suggest you to follow a few simple steps listed here.
This is just a quick post to share my first 3.1.1 Oracle VM Manager (OVMM) troubleshooting experience. After the initial installation I rebooted the server, tried to access OVMM https://ovmmhost:7002/ovm/console and received the following error in a browser screen…
It happens to be very short blog post as installation the Oracle VM Manager 3.1.1 under Dom0 host isn’t different from installing the previous version. For all tricks that you need to use please see my Oracle VM Manager 3.0.3 under Dom0 post.
I think the results we got so far may surprise you. At lease those doesn’t seems to be the results +Alex Gorbachev and +Kevin Closson expected to see. You can find the first related blog post over here. It will give you the necessary context for further reading. Just to recap: +Kevin Closson says “Orion may give It’s VERY easy to get huge Orion nums but reasonable SLOB” and +Alex Gorbachev “lots of the system IO bound below the CPU level so you should see similar number with Orion or SLOB.” Let see what first testing results revealed.
