Performance Enlightening - Craig Effect (Tropa de Elite)

Ver este articulo en Español

During the past week I had the opportunity to assist both the Oracle Performance Firefighting and the 

Advanced Oracle Performance Analysis and only can say: awesome!!!

Craig Shallahamer is a great teacher and has a lot of resources to effectively share knowledge, even if 

the subject is complex like buffer cache structures or arid like the mathematical foundation required for 

perf analysis. That is not all, he provides valuable tips of the trade or anecdote nuggets, dipped on a 

very fresh and sometimes humorist perspective.

The result: we started searching for those AWRs and Statspack reports that were difficult to analyze, I even 

recalled some unsolved performance cases that stained my record; difference now, is we all have the 

analytical elements to properly handle these and new challenges.

Awesome, Oracle enters the Hardware arena!!!

Yeeeesss,!!! Larry Elison is releasing right now at OOW2008, which is the first attempt to enter the hardware market, in partnership with HP, offering which is the greatest improvement on Database technology, with improvements on performance that range from 10x minimum, Exadata establish a milestone for Oracle and the IT Industry.

This product, which he labels as a "Database Machine", has been under development (secretly of course) for 3 years, and proposes adding inteligence to the storage and multipling the storage capacity.

Packed with Oracle software, up to 168Tb on disk storage, 64 CPU cores provided and assembled by Hewlett Packard; results are astonishing, with benchmarks showing improvements on performance by x28 and hardware space savings that may make a hot-sell product, maybe as hot as the iPod, all proportions.

After this great surprise, I think this OOW2008 has been a breakthrough, I franquly need to recover the breath...

For DBAs, Storage Managers and SysAdmins... there is another toy we must learn, and master.

Stay tunned, here at OOW2008, San Francisco.

Intel offers Time travel at OOW2008

I'm writing online at the keynote with Paul Otellini, after the strong commitment signal expresed by Oracle that Intel is their preferred platform.

He is introducing us to a brief historic recount of CPU, Business (example FedEX) and Animation (example Dreamworks) milestones.

The core idea is a perspective of accelerated demands our computing systems are facing, and succesfully achieving through the improvements the chip makers are offering to the market, specially Intel. The summary shows that Intel is helping to do more within the same time, which in perspective may be interpreted as a "slowing" time effect.

Shared with us the benchmark results for the brand new Xeon 7400 which with his 6 cores and capabilities for working concurrently with up-to 16 sockets, overpasess the Xeon 5400 and Itanium products. The commercial spot is "Oracle runs better on Intel".

Revealed next innovation steps on Itaniun Tukwila and Xeon Nehalem EX, with count above thousands of millions of transistors.

Intel support to multicore exploit coulnd't be more encouraging, they've developed and are offering a tool to discover the parallel oportunity on current application's code.

Enterprise Cloud is a task that Oracle and Intel pretend to tackle in tandem. With deep cooperation among them, that goal seems already done, and we may see fruits from that tree quite soon I guess.

Stay tunned, I'll continue this OOW2008 covering

Oracle New Releases at OOW2008

Charles Philips (President) and Chuck Rozwat (EVP Product Development) have released what seems the next evolution step for Collaboration Suite: Oracle Beehive, which promises to tackle the collaboration fragmentation problem, once and for all. What means for us DBAs? that me may administer in the future:
1) more infrastructure that today is serviced by Microsoft or Lotus products
2) more data growing into our storage infrastructure

Also announced the availavility of a new update for 11g, which is internally labeled as 11.1.0.7 for Linux, with this Oracle continues improvement of their flagship product.

Low at the tech stack, they showed improvements to Oracle VM and their commitment to Linux. Must say Oracle is pushing hard with their VM offer, even with 'orthodox' meassures like no-certification for non Oracle VM solutions; we honestly expect to see that strategy difuse over time.

Stay tunned

at Oracle Open World 2008

It is my first time, and must say this event Rocks!!! There is a lot of people from allover the world, here are the experts and gurus, sessions are great, the OTN lounge is by far the best one. Anyway this event is a must for anybody working with Oracle products.

I scheduled an Unconference session for Tuesday 22th 11:00am, was "Capacity Planing with Oracle tools". I've to say I got a small group of people, but they were very interested on the topic. It's a great experience if you conduct a session, but it's greater if you are the speaker in a language which isn't your mother tongue, is quite challenging.
