My First Experience with Cassandra – Part 1

The traditional NoCOUG SQL challenge has been launched this year with a twist: In the wake of the “BigData” trend/buzz, it’s now been upgraded to a “SQL and/vs. NoSQL” challenge. I took on the challenge, treading through my SQL comfort zone and thinking of ways I could bend relational algebra to solve the wicked puzzle suggested this year.

War Story: Applying Bundle Patch 1 to EM 12 Cloud Control

We have a few clients already using Enterprise Manager 12c Cloud Control. The interface and navigation have improved a lot from the 11g version in my opinion. However, as with any new release of anything, quite a few bugs still need to be fixed.

The first thing that I noticed when I started looking for information about BP1 was the amount of warnings from different people I found in MOS and around the internet.

Upgrade Exadata to 11.2.0.3

I’ve recently done two Exadata upgrades to 11.2.0.3 and want to share the experience. I hope this short note will help someone to make the decision, calculate an estimation, and prepare for maintenance. I am going to talk about upgrade from the version 11.2.0.2 BP10 to 11.2.0.3 BP2.

Oracle Database Appliance as a Consolidation Platform

I had the chance to talk to several Oracle Database Appliance users at the annual Collaborate 2012 conference last month in Las Vegas. A common theme in these discussions, as well as discussions with Pythian clients, is an interest in using the ODA as a large-scale consolidation platform.
