Following up on my earlier webinar Implementing Oracle Exadata – Strategies for Success, I’ll be giving another webinar to present the results of the Exadata implementation at LinKShare. I’ll be talking about actual performance results, our zero-downtime go-live, compression experiences, and performance tuning in an Exadata environment.
Just recently I came across another unclear error message while troubleshooting an Oracle Instance registration with SCAN Listener. This post is one of the posts which may save quite a bit of time for people who will hit the same issue.
I’m happy to announce the winners of this year’s t-shirt and creative blogger’s contest at the Oracle OpenWorld 2010 Annual Bloggers Meetup. Asif Momen, of the Momen Blog was the big winner of the HP X310 DataVault. Although there wasn’t as much participation as I had hoped for the creative blog post contest we have not one, but two AppleTV winners to announce; Sunil S. Ranka for his post: Mapping the Maze, Online Bloggers to Real World Faces: Pythian Blogger Meetup at OOW10 and Mr. Chet Justice, Oraclenerd for his entertaining, 5 part series from the meetup. Definitely an “A” for effort – could you tell he really wanted the AppleTV?
If you ever had tried to switch Oracle net trace than you know that it is quite straight forward to switch it on. You would say that I need to set the following parameters in the sqlnet.ora file…
After over a hundred hours of hard work, Pythian has achieved multiple specializations under our Platinum membership level of the Oracle PartnerNetwork’s OPN Specialized program. We’re proud to be recognized by Oracle as a value-added services partner.
ourSquare, the location based social network, suffered from extended outage yesterday. They explained the causes in a blog post, which caused much discussion around the web. Here’s the gist of the analysis: FourSquare are using MongoDB, which is a sharded database. Data is split between nodes based on a shard key, usually the User ID or something similar. One of the shards became overly loaded. After failing to resolve the issue in other ways, FourSquare decided to add another shard to share the load. This caused the entire cluster to fail.

I wrote my very first Catalyst plugin, and it’s going to be something useful for Galuga. As I don’t have a lot of time, I’ll be succint. As you’ve doubtlessly gathered by now, the name of the game is Catalyst::Plugin::Sitemap. It’s on Github, but it’s not CPANized yet. To use it, add the plugin to your Catalyst app main module
If you have tried to automate EBS cloning then you definitely know that you can’t get through without hacking and customizing the Oracle-provided Rapid Clone utility. One of the areas we should “hack” the code to make it running in batch scripts is the services startup bit. The problem is that by default straight after Rapid Clone is completed Oracle starts all the services on the Apps node and until now there wasn’t a way to change it.
It looks like our lucky recipients of plane rides with Sean D. Tucker had a great time. Pictures are below. Thanks again to Team Oracle for facilitating the flights.
