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.

If you are interested in the topic of ODA performance but missed the webinar or if you want to hear it again, you can view our recording here. I also uploaded the slides to slideshare, so you can take a better look at our benchmark results and study our consolidation methods at your own pace.

At work, we have a need for a little job daemon that would poll jobs and process them. But there is more than one type of job, so the solution that we need will have to be a little more complex. To get to my goal, I decided that I would have a generic Poller class. For each type of job to monitor and run, I will create a different object with parameters to tell it how often to poll, how to poll, and what to do with the stuff it polls. Sounds good? Perfect, then let’s go.
We now know beyond a shadow of a doubt that new media technologies like Twitter and Facebook are not going to wipe-out blogs but are rather complementing them very nicely. It seems they were made for each other. This Log Buffer Edition enhances this match. Enjoy.

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…
