Ready for Reactivity?

Sure, you've been busy, but hopefully not too busy to notice that...

...Application requirements have changed dramatically in recent years. Only a few years ago a large application had tens of servers, seconds of response time, hours of offline maintenance and gigabytes of data. Today applications are deployed on everything from mobile devices to cloud-based clusters running thousands of multi-core processors. Users expect millisecond response times and 100% uptime. Data is measured in Petabytes. Today's (more...)

OOW14 day 0

w00t! One compound word? Mind-boggling!



As a first time OOW participant, when I arrived at Moscone this morning, the sheer size, grandeur and general over-the-top-ness hit me like a brick. Seeing it in pics and on youtube is one thing but experiencing first hand...wow. KScope back in June was a family party in comparison! Which isn't a bad thing by the way

For me, Sunday was all about getting my bearings and participating - (more...)

Oracle OpenWorld 14 Day -1

Saturday was a rather quiet day. After having spent 2 hours on Friday night, trying to get the connectivity working in my hotel room, Friday started out with another almost 2 hours which culminated on a recabling of the room and replacement modem to finally get things working. After that I was able to put the finishing touches to my presentation.

Lunch was...american. Very american. Think 50s-type diner. Think chili-chedder-hot-dog. Think fries. LOVE IT! (more...)

Responding in Real-Time with Big Data By Mala Ramakrishnan

| Aug 4, 2014

For an organization to respond in real-time it needs to acquire or develop systems
that can respond in real-time. Such systems need to be able to rapidly
determine that a response is required and determine also what the
appropriate and relevant response should be – they need to decide when
and how to act. These kinds of decision-making systems are known as
Decision Management Systems. To ensure that a response is delivered in
real-time, more (more…)

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 (more...)

Speaking at E4 2013! … and some Exadata Patents good stuff

I’ll be co-speaking with Tyler Muth at E4  and we will be talking about Performance Visualization… some of you may already know that I’m really a big fan of Tableau and just to give you an example on what the tool can do I’ve consolidated all the different viz that (more...)

RMOUG, IOUG Collaborate, KSCOPE, and E4 2013

I’ve been really busy lately doing a lot of stuff, and most of the time if I’m doing some intensive research on a topic I would just put them all in my braindump (wiki) so if you’ve been following this blog might as well subscribe on my wiki RSS because there are just a bunch of bits of research going-on (see this mindmap) and what usually happens is I put them all together to make an awesome presentation/white paper.

So this 2013.. I’ll be presenting at RMOUG, IOUG Collaborate, and KSCOPE 2013 ;)

If you’ll be at RMOUG next (more...)

OakTable World 2012

This Monday Oct 1, 2:00-2:50PM I’ll be presenting at the OakTable World which used to be called as Oracle Closed World, this year it’s a full two-day conference with awesome speakers lineup and very interesting topics… you can just watch this video by Mogens Norgaard to know more about the roots of this very technical event.

My presentation title is “Where did my CPU go?” – monitoring & capacity planning adventures on a consolidated environment .. and If you love to hack the ASH and AWR data and curious about CPU capacity planning then you’re really going to enjoy (more...)

Speaking at E4!

I’ll be co-speaking with Randy Johnson (one of the authors of Expert Oracle Exadata) at E4 to share about the war stories and detail on a bunch of technical stuff on a Peoplesoft and BIEE consolidation project we had on one of our clients. See the abstract below:

Randy Johnson & Karl Arao
A PeopleSoft & OBIEE Consolidation Success Story
In today’s competitive business climate companies are under constant pressure to reduce costs without sacrificing quality. Many companies see database and server consolidation as the key to meeting this goal. Since its introduction, Exadata has become the obvious choice for (more...)

RMOUG 2012 training days

In the next few days I’ll be at RMOUG 2012 training days! and I’ll be again presenting the topic so dear to my heart. Mining the AWR ;) I’ve updated the material with a couple of new research and findings, some of them are as follows:

  • CPU Wait (new metric in 11g Performance page)
  • Latency issues on virtualized environments

So if you are attending the RMOUG training days, stop by at my session @ room 401 Thursday 9:45 am-10:45 am

There will also be a RAC Attack at the exhibition area so that must be fun ;)

and don’t forget to follow (more...)

VirtaThon – Mining the AWR

Earlier I did a presentation at VirtaThon which is the same topic that I presented at Hotsos 2011.. Mining the AWR and Capacity Planning are very dear to my heart and up until now I’m using every research I did on that presentation to work on an “Exadata Provisioning Tool” which I’m planning to present at the next Hotsos 2012… well, the only thing that’s different this time is.. my attendees are virtual geeks all over the world ;)

I was at the Virtual Room #100, and the staff earlier were really helpful and most of all I had fun (more...)

Enkitec University – Exadata Courses for Developers and DBAs

It’s been a long time since my last blog and ever since I joined Enkitec I’ve been busy immersing myself in Exadata stuff. So most of the time I’m just posting my brain dumps on my wiki although I know there’s a lot of blog worthy scenarios and projects that I have worked on just like last week when we did an Exadata Half Rack X2-2 Split Configuration from the factory image without the use of Oracle’s ACS. We did all of the pre-config and config tasks like the onecommand, patched the database to 11.2.0.2 BP8, patched (more...)

NoCOUG Journal – Ask the Oracle ACEs – Why is my database slow?

Dave Abercrombie mailed me earlier that the May 2011 NoCOUG Journal is already out and can be viewed online at http://www.nocoug.org/Journal/NoCOUG_Journal_201105.pdf.

I met Dave at Hotsos 2011 when he attended my presentation.. apparently we have the same interest about Statistics, Linear Regression, AWR, AAS and he’s got awesome blogs about it at http://aberdave.blogspot.com. Also being the Journal Editor at Northern California Oracle Users’s Group, he invited me to write a short article about the question:

Why is my database slow?

The NoCOUG Journal having a very wide readership with the last issue being downloaded around 6000 times from (more...)

Oracle by Example portal now shows 12g

A quick post… which is a bit interesting…

As I was searching for Exadata viewlets in Oracle By Example portal (http://goo.gl/HjshR) I clicked on the “Advanced Search”

and then filtered by Product Family (Database) and then by Product

to my surprise there was an option for “Database 12g”….

oh well.. I checked on the Lifetime Support Policy (http://www.oracle.com/us/support/library/lifetime-support-technology-069183.pdf) and looking at the release dates
it could be possible that they will release the new version anytime this year..

could be in Oracle Open World 2011? hmmm… ;)

 

 


Hotsos 2011 – Mining the AWR Repository for Capacity Planning, Visualization, and other Real World Stuff

For all that loves Oracle performance.. Hotsos is truly the best conference, all the speakers are performance geeks, all the attendees talks about performance. Everything is about performance! There are lot more stuff that I like about my first Hotsos experience, the following are some of them..

I like that presenters and attendees are curious about what each performance geek has to say..

I like that whenever their brains are already fried. They consume as much coffee/soda as they can.. and just lay their butts on this couch.. and still.. talk about performance.

I like that after all the sessions, (more...)

I’ll be speaking at HOTSOS 2011!

Hotsos is an annual conference that is devoted on Oracle system performance and the people presenting there are really passionate about their research and highly specialized about their subject area. Kinda geeky, but hey, performance is never boring.. and for me there’s still a lot of things to learn on each of the areas of performance and these are as follows: 
  • Application Testing
  • Benchmark
  • Capacity Planning
  • Database Tuning
  • Hardware and OS
  • Performance Tools
  • SQL Tuning
  • Troubleshooting & Internals

Yesterday, I received an email that I have been accepted as a presenter for Hotsos 2011 ;) this is really cool .. !

OOW 2010 – my schedule



I was able to finalize my schedule a week before the OOW 2010 and most of the sessions that I’ll be attending are related to Performance & Exadata.

So that would be:

You can check my detailed schedule below … (I know it’s a jam-packed sched! I hope I can go to all of them..)

This will be my first time attending the OOW and I’m sure I’ll be having a superb time ;) I’m registered as a Blogger so I got (more...)

“Ideas build off ideas”… making use of Social Networking sites

OracleUsersPh

In this post (which has been looong overdue :p ) I’ll show you how you could make use of Social Networking Sites to make knowledge sharing and meeting people more fun. As you can see from the illustration above, I’ve made use of the following sites/services to build a dynamic and multidimensional means of communication:

  • Facebook
  • Twitter
  • FeedBurner RSS
  • FeedBurner Mail Subscription
  • Google Sites
  • LinkedIn

The story behind it…

I am a DBA for 4years+, and started with zero knowledge about Oracle. I joined SQL*Wizard, which has a great training program and exposed me to a lot of difficult (more...)
