One of the things I love about my career (Oracle DataBase Administrator) , is how fragile it is on a day in and day out basis. I can say with certainty , that every day I turn on my laptop to start working, it can probably be my last day working as a DBA, and…
It is an industry norm, supported by analyst researches that blogs are the best informal medium to share the information. This unique medium provides readers with increased leverage in negotiating the hard turns in their technological lives. Log Buffer makes that leverage more powerful.
This is a short blog post on how one can prove that a particular partition of the table or index is accessed by a specific query.
A little while ago I blogged about (and open sourced) an Impala-powered soccer visualization demo, designed to demonstrate just how responsive Impala queries can be. Since not everyone has the time or resources to run the project themselves, we’ve decided to host it ourselves on an EC2 instance.
As per many previous IOUG/OAUG/Quest shows, Pythian is will be in Denver next week! It was a sunny day in the fall of 1991 when I gave my first paper at International Oracle User Week (IOUW), a pre-cursor to COLLABORATE and a few earlier incarnations called IOUG-Live and IOUG-Alive! It has been a whirlwind of…
There’s a rare event happening next week: All three of Pythian’s Oracle Apps tech leads will be in the same place. Vasu Balla, Maris Elsins, and recently-minted Oracle Ace Director Yury Velikanov will all be at Collab 13 this year.

There are so many interesting sessions to choose from! Conference organizers kindly introduced a Show Planner to make planning a bit easier, but in this blog post, I will share with you how I created my agenda for Collaborate.
First, the most important advice I can give you is to relax and have FUN! Personal Experience Until recently, most of the conferences I participated in were very stressful for me personally.

Building a secure Hadoop cluster requires protecting a number of services which comprise Hadoop infrastructure. If you are using CDH distribution, then Cloudera Manager (CM) is one of the components that needs to be secured.

There are different approaches to the problem of managing server’s configuration at scale, but I’d like to focus on Ansible which is a neat framework for parallel commands execution and complex rollouts.
This is a very short blog post to share a good news I learned last week at the great New Zealand Oracle User Group 2013 conference. During a keynote Tom Kyte mentioned that Oracle is going to introduce a Temporary Undo.
