Resource usage on Exalogic

with one comment

For the coming  conference season I decided not to present. I have had plenty of interesting experiences, multiple could be interesting enough to present about, but working with new products requires so much energy that I rather skip for now. Right after this decision I noticed that I just can’t help myself. I like to share what I do, not only to share but also to learn (and perhaps even being told that I am wrong).

The last two years loads of my work has been around engineered systems. Last year (2014) I was involved with multiple customer as platform architect deploying all kinds of engineered systems, including a total of 11 racks Exalogic (either half or quarter) . Most of these racks were fitted with OVM (a.k.a. Exalogic Virtual), five of these were Hybrid (half “bare metal” and half OVM). There are plenty of things to say about the Exalogic product, what does and what does not work, what is missing etc. I would like to stay away from all that, not in the least because Exalogic 12c has been announced. Therefore I just share some of the tooling, scripts and notes that I wrote to support my every day work.

One of the topics that my customers keep on asking questions about is actual resource usage. Obviously tooling like Oracle Enterprise Manager can help with that, however not every customer is running OEM (yes these customers exist and have numerous reasons). So that leaves you, as consultant/administrator/local-techie with a challenge, how to find how many VMs are actually running on your rack. Especially the control stack of Exalogic does not have any features that makes output excel-friendly (apparently a must-have feature for any resource report).
