Along comes the Oracle RAC Special Interest Group (SIG) which is appearing at a conference near you. At Oracle Open World 2012, RAC SIG personnel will be on-hand running RAC Attack – a hands-on lab where you can build a cluster on your Windows, MAC, or Linux personal computer. This is a dream come true. I first did RAC Attack at the UKOUG show in Birmingham last December.

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.
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.
