For the final day of UKOUG there are quite a few Pythian presentations. Unfortunately a lot of them happen at the same time, so it won’t be possible to attend them all live.
On tap for Tuesday is a 2-hour master class from Michael Abbey, along with an all-day drop-in RAC attack workshop with Alex Gorbachev and the RAC SIG.
For those of you attending UKOUG today, there is a healthy dose of Pythian presentations on tap this afternoon. Actually, you can do it wall to wall 2:30pm to 6:30pm if you like.
I was just looking at an Exadata X2-2 ordering document and noticed that it included 144GB of RAM. The sales rep pointed at the Exadata X2-2 datasheet and showed the 96GB to 144GB memory expansion option.
The website for Oracle Database Cloud Services is now online. It’s a hosted database service running Oracle 11gR2.

If you’re using the cellmonitor OS user run commands other than a plain cellcli, this may stop working on upgrade. This would happen if custom scripts were built to do additional monitoring that’s not part of cellcli.
Oracle Database Appliance (ODA) is in many ways similar to an Exadata quarter rack: they both use two similar compute servers in an engineered system configuration, with shared storage and flash storage. But in other ways, especially networking and storage, they differ significantly.
I’ve started putting together some information about the Oracle Database Appliance in question-and-answer form. If you have an unanswered question, ask away in the comment section in this post.
Greg Rahn of Oracle’s real-world performance group posted a technical review of an article I wrote last summer, entitled Making the Most of Oracle Exadata. I have a few comments on the technical concerns Greg raised.
For those of you in the New York City area, I’ll be speaking at the NYOUG joint BI/DW and Web SIG meeting. The topic will be a case study of Pythian’s Exadata implementation at LinkShare.
