User Group Sunday at Oracle Open World 2013

I’m relaxing before tonight’s keynote. Spoke twice today during User Group Sunday; both talks went well. First talk (8am) was for ODTUG and the ADF EMG titled “Oracle ADF Task Flows: Beyond the 10-Minute Demo”; the audience started small but became respectable by the time the session was done. I need to fit a demo into this session to liven it up a little!  The second talk was at 11:45 for IOUG; I had a packed room to see “Oracle 11gR2 and Oracle 12c New Features for Developers” – lots of interaction and demos went well. I’ll be doing a 12c-specific talk on Thursday at 12:30 in Moscone West. I also attended some good sessions; perhaps my favorite of the day was Wilfred van der Deijl and Paco van der Linden talking about “Worst Practices for Developing an Oracle ADF Application” – if you are interested in ADF you should download the slides for sure.

My 1st Ace Director briefing

My 1st Oracle Ace Director briefing finished Friday afternoon; two information-packed days and the opportunity to talk to other Ace Directors and Oracle people too. Oracle has lots of exciting new products and features on the way. This was time well spent!

Oracle Open World- Sunday!

The ACE Director briefings are done and now we are onto Sunday sessions.  I’ve already had a couple meetings with folks today and wondering why I didn’t wear flats at 2pm in the afternoon, but there are the important necessities that must be taken care of, like when am I speaking this week, so here’s the schedule:

OOW and OakTable World 2013

Today is the 1st day of OOW for me, and there are a lot of cool stuff going on.

Sessions:
——————–

Later I’ll be doing an IOUG session at Moscone West talking about CPU on how to monitor and do capacity planning and
sizing. This is a pretty interesting topic and I will give you enough foundation to be able to consolidate a bunch of databases on one server or a cluster. There’s a method to this and you can be pretty accurate about it. Remember 12c is geared towards consolidation but it doesn’t really change the fundamentals when monitoring and sizing CPUs.. I’ll just talk more about that later.

Session ID: UGF9790
Session Title: Where Did My CPU Go?
Venue / Room: Moscone West – 3014
Date and Time: 9/22/13, 15:30 – 16:30

Q&A
Q: Do all these methods of showing execution plans work (dbms_sqltune, dbms_xplan) with Oracle Standard Edition?  What about creating extended statistics in Oracle SE? Do all these tips work with SE? Is SQL Monitor a licensed product?

Alleviate load on SANs with Data Virtualization


 

by Matt Hayward

One of the less obvious advantages of database virtualization is a reduction in the read I/O issued against the underlying physical storage (henceforth called “the SAN”) that ultimately stores the data for virtual databases.

In practice, Delphix prevents around 60% of all non-production database I/O* from ever being issued to the SAN with the Delphix cache.
