Set Up Exadata for Cloud Control 12.1.0.2

I recently helped setup an Exadata X2-8 Database Machine with the latest version of OEM Cloud Countrol (12.1.0.2). A few documents do exist for this process – the most useful of which are the Exadata Discovery Cookbook and the Setup Automation Kit. However I found a few inconsistencies and problems; I think the existing documents I found were written on older versions of OEM and older versions of the tools. Also there are some additional steps for older Exadatas which didn’t apply to my case.

Adaptive Log File Sync: Oracle, Please Don’t Do That Again

Disclaimer: much that follows is pure speculation on my part. It could be completely wrong and I’m putting it out there in the hopes that it’ll eventually be proven one way or the other.

Lessons from Africa, Part 2

Last week was busy… making travel arrangements for this week’s trip to New York (technically Jersey) and some light analysis of AWR reports from exadata RAT runs and some heavy troubleshooting of a Solaris x86 RAC cluster with random node reboots. (I think I finally traced the node reboots to a kernel CPU/scheduling problem). I really did thoroughly enjoy my time in Africa despite being nowhere near Oracle software – but it feels good to be working on challenging cluster problems again!

Lessons From Rural Africa

It has been nine months since I’ve written here. Needless to say, a lot has happened!

First, my family was living in Africa for three months earlier this year while I did some tech work at an NGO hospital. Second, upon our return I decided to join the good people at Pythian. I’m not moving to Canada, although I will travel a decent bit as part of the company’s consulting group.

If you’re interested in the Africa trip, look at the Africa page. I wasn’t working with Oracle technology but it was still a very interesting, challenging and engaging project.

I thought I’d briefly share a few high-level insights. You might be surprised how well these lessons apply almost anywhere (even Oracle-related projects)!

Making Simple Performance Charts

Before I dive into this blog post, quick heads up for anyone attending UKOUG: on Tuesday only, I’ll be hanging out with some very smart people from the IOUG RAC Special Interest Group in the “gallery” above the exhibition hall. We’re ready to help anyone run a RAC cluster in a virtual environment on their own laptop. And if your laptop doesn’t meet the minimum requirements then you can try with one of our demo workstations. Come find us!!

Why Make Charts

I’ve heard Kyle Hailey speak on a few different occasions, and more than once he’s talked about the power of visualizing data. (In fact Kyle was a key person behind Grid Control’s performance screens.)

RAC Attack in OTN Lounge at OOW11

Want to get your hands on a key technology in both the Exadata Database Machine and the newly announced Oracle Database Appliance?

If you’ll be at OpenWorld – in just 11 days – then the IOUG RAC SIG is putting together a special event for you!  (You might have already heard about this on Twitter or from Justin at the OTN Blog.)

Every day from 9am to 1pm, find our table in the OTN Lounge (on Howard Street) and we’ll help you get an 11gR2 RAC cluster database running inside virtual machines on your own windows-based laptop. You can experiment boldly – if you make a mistake then you won’t have to start over; we can easily “reset” your virtual machines to any point.
