Oracle OpenWorld 2012 : Day 5

Day 5 was a presentations day for me.

I tried to make as many motes as I could, but you will see the quality and accuracy of the notes tail off as the day went along… :)

Tom’s Top 12 Things About the Latest Generation of Database Technology

My bullets don’t quite match Tom’s, which is why I have more than 12 things listed. :)

Oracle OpenWorld 2012 : Day 4

My RAC Attack session was pretty early, so I headed straight there for the morning.

The OCP lounge always has drinks and food, so regular pitstops there are the norm for me at OOW. If you have OCP or above, it’s really worth dropping by on the first day and getting your ribbons, so you can do regular refreshment stops during the week. :)

After RAC Attack it is was back to the demo grounds to do another quick tour. Basically, I was looking for new faces to speak to and quizzing people further about stuff I had discussed on previous days. Sometimes you have to let this stuff stew a while before you can think of more questions. :)


Thanks to all those people that attended my session last week at OpenWorld.

A number of people have asked for copies of the slides.  I will post them here as soon as I get back home to Perth.

Thanks for your patience.

So OOW 2012 is over – it was a pleasant and interesting week. Cary’s closing presentation was a joy to listen to and a great way to end the conference.

I’m sitting (actually standing – I’ll be sitting for most of 10.5 hours soon enough) in the BA lounge at SFO, sipping a remarkably nice Chardonnay: The Director’s Cut 2010, from the vineyards of Francis Ford Coppola. Lightly oaked, and a lovely compromise between the delicate sparseness of the Old World and the usual fruity agressiveness of the New World. It’s quite hard to resist the second glass – but if I don’t the flight home will be tough.

Thanks to those who have donated to my son’s half-marathon for malaria. It takes place on Sunday, so I’ll probably be somewhere on the route cheering him on, but I haven’t picked a spot yet.






There’s never enough time to read everything that’s worth reading, so even though Guy Harrison’s blog is one of the ones worth reading I find that it’s often months since I last read it. Visiting it late last night, I found an interesting batch of articles spread over the last year about the performance of SSD – the conclusions may not be what you expect, but make sure you read all the articles or you might end up with a completely misleading impression:

250 Posts !!

WordPress reported that my last post on Exadata Storage Indexes was my 250th !! Who would have thought …

Openworld day 4

Its the penultimate day at openworld

First up was Gwen Shapira’s ( talk on Big Data and its integration into the "enterprise" and database.  This was perhaps the most relevant of big data talks this week, because I imagine anyone at an Oracle conference already has some (significant) investment in what could be called "conventional" database technology, and might be looking at how "big data" is going to fit into that picture.

So Gwen gave an excellent overview into how this might occur, why it might occur, and some strategies on how to do it without spectacularly failing :-)  

Indexing 12c

Another little detail that Hermann Baer mentioned in his presentation yesterday was the ability to create multiple indexes with the same column definition – something which currently gets you Oracle error “ORA-01408: such column list already indexed.” 

No details, and there’s always the “safe harbour” slide of course – the one which says seomthing about the presentation being only an indication of current thinking and nothing is guaranteed to appear.

Exadata Storage Indexes – Part I (Beginning To See The Light)

Thought I might discuss Exadata Storage Indexes, explore what they are, how they work and discuss their advantages and disadvantages. Following is but a brief introduction on this very cool Exadata feature. A Storage Index basically maintains summary information about database table data down on the Exadata storage servers. The information consists of the minimum value, the maximum […]

Oracle OpenWorld 2012 : Day 3

Day 3 was similar to day 2 for me. I spent a lot of time hanging around the RAC Attack sessions. A lot of people pass through, so in addition to helping people set up virtualized RAC, there are always interesting people to talk to.

I did some serious demo grounds cruising again, including:
