A simple 12c query with a cool result …

Its not immediately obvious the significance of this query…but trust me…you’ll love it :-)

We are starting a limited publicly accessible download of a trial version of Delphix and lab.

Jonathan Lewis explains Delphix

OOW 2014 was the best so far for me and a whirl wind.  After not having a presentation accepted since I left Oracle 10 years ago, I got not only a presentation accepted but 3 presentations accepted. Woohoo! Two of my presentations are available on youtube at

On top of that with the awesome support of the Oaktable, Delphix, Pythian and Enkitec , I was able to secure a great venue for the 3rd annual Oaktable World at OOW where we had the leading Oracle performance and internals experts speak for 2 solid days. You can see videos of the Oaktable World presentations at

Mobile Front and Center at Oracle Open World 2014

Wow! Sorry I have not posted anything since Oracle Open World. Lot’s of great new stuff is coming from Oracle that you should look into including some pretty cool stuff for mobile development.

DevOps and Databases?

I’m super looking forward to next weeks DevOps Enterprise Summit in San Francisco. You might ask “Why?!” since I’m a database guy and not a DevOps guy.  I can understand that reaction.

I don’t know about you, but when I hear the term DevOps I have to roll my eyes and think “oh, the latest greatest tech industry buzzword.” So why would I as a DBA care about DevOps? With DevOps, as with most tech industry buzzwords, there is actually a worthy idea at the kernel. The kernel of DevOps has two parts.

Memory

On a client site recently, experimenting with a T5-2 – fortunately a test system – we decided to restart an instance with a larger SGA. It had been 100GB, but with 1TB of memory and 256 threads (2 sockets, 16 cores per socket, 8 threads per core) it seemed reasonable to crank this up to 400GB for the work we wanted to do.

It took about 15 minutes for the instance to start; worse, it took 10 to 15 seconds for a command-line call to SQL*Plus on the server to get a response; worse still, if I ran a simple “ps -ef” to check what processes were running the output started to appear almost instantly but stopped after about 3 lines and hung for about 10 to 15 seconds before continuing. The fact that the first process name to show after the “hang” was one of the Oracle background processes was a bit of hint, though.

Delphix and Oracle 12c partnership

More and more people have been asking me how Delphix compares with Oracle EM 12c Cloud Control with Snap Clone.

Delphix compliments Oracle. Oracle and Delphix are partners.  Delphix is an Oracle Gold ISV partner and we collaborated at Oracle Open World on hosting hands on Delphix labs.

Openworld

Well, the annual spectacle of enormous proportions has come to a conclusion again. And thats probably the first reason I’d recommend OpenWorld to anyone who works with Oracle who has never been to it. It’s a jaw dropping moment just to see the scale of the event, and how impressively its organised in terms of facilities, lunches, registration and the like.

But onto the technical elements, here’s my impressions of this years conference:

1) Big data, Big data, Big data, Big data

Where the real technical talks are at OOW

What are the real technical talks at OOW amid all the marketing fluff? I don’t know all of them but I can vouch for the following
