What technology has most changed your life? Oracle Database. Using it has given me the honor of presenting at Oracle OpenWorld, on the APAC OTN Tour, and at TROUG [Turkish Oracle User Group] conferences. I’ve also blogged about my experiences with Oracle Database [see kamranagayev.com] and helped to establish the Azerbaijan Oracle User Group [AzerOUG]—both of which have expanded my social circle.
How are you using social media in your work? As a blogger, I try to share problems I encounter in my daily job. I also record step-by-step video tutorials and share them on YouTube, Twitter, and Facebook. And whenever I’m at an Oracle-related conference, I tweet from almost every session I attend about anything new.
You’ve taken Oracle University [OU] classes in the past. What led you to do this? I wanted to learn Oracle from Oracle. OU classes are very well structured. They’ve really helped me to update my skills and prepare for the Oracle certification exams.

Oracle ACE Director
What’s your favorite tool on the job? DTrace is a very powerful analysis tool—other similar tools just aren’t as intuitive. And performance analysis is so important for ensuring security, which is the focus of my business. I also appreciate the fact that DTrace can be utilized in both Oracle Enterprise Linux and Oracle Solaris.
What are your favorite mobile applications? Evernote and Oracle Hardware Virtual Tour—a 3-D product catalog.
What’s your favorite Oracle technology user group? The Korea Oracle Solaris User Network. I’m the group’s chairman. The technical understanding among our members is high, and we really help each other. As a member, you can get truly valuable technical assistance through the Q&A section of the group’s online bulletin board—and that’s also a great place to create and share technical documentation. We also promote knowledge sharing through a variety of conferences and offline seminars.
Company: e-dba, an Oracle Platinum Partner providing managed services and professional services support
Job title/description: Senior principal consultant, part of a team of Oracle Exadata DBAs focused exclusively on e-dba Oracle Exadata customers
Location: Oxford, England
Length of time using Oracle products: 14 years
How did you get started in IT? I really got started while pursuing a PhD in nuclear physics in the mid ’90s. I was using a Sun workstation and essentially being the system administrator for it. This led me to become a Sun system administrator, and from there I got to work with Oracle technology—and realized that I actually preferred being a DBA.
What’s your favorite technique on the job? Using the Oracle wait interface. The Oracle code is well instrumented, and being able to see where a session or statement is spending time is a very useful technique.
Which new features in Oracle Database are you currently finding most valuable? I do a lot of consolidation work with Oracle Exadata, and the pluggable databases in Oracle Database 12c are great for that.
What’s your go-to Oracle reference book? Practical Oracle8i [Addison-Wesley Professional, 2000] by Jonathan Lewis and Optimizing Oracle Performance [O’Reilly Media, 2003] by Cary Millsap and Jeff Holt. These books are more than 10 years old now, but they’re still valid today. I know I was a better DBA after reading them.
