A couple of months ago I did a presentation and decided to put the files up in github (https://github.com/karlarao/conference_eco2015) just because I wanted to move away from dropbox for my scripts and resources. Well, that was very convenient because the audience can just download the master zip file and that’s it! But then I figured I don’t want to have the next presentation on another repo and it would look pretty messy (more...)
There was a post last night on oracle-l on the topic of task/project/time management, and I’m a big fan of productivity hacks and the whole GTD idea or method http://en.wikipedia.org/wiki/Getting_Things_Done. The reason for adopting this method is I’ve been on consulting business my entire career and I always get swamped with a lot of work from multiple customers or research stuff and it’s really difficult to prioritize and focus without a system. The same (more...)
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...)
Lunch was...american. Very american. Think 50s-type diner. Think chili-chedder-hot-dog. Think fries. LOVE IT! (more...)
Today is the 1st day of OOW for me, and there are a lot of cool stuff going on.
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...)
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...)
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...)
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...)
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...)
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...)
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 188.8.131.52 BP8, patched (more...)
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...)
