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.

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…
This blog post will be short since installing the Oracle VM Manager 3.1.1 under Dom0 host isn’t different from installing the previous version. For all the tricks 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 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.
