What’s your favorite technique on the job? I love any technique that has the word rolling in it: rolling database upgrade, rolling patches, rolling Oracle server software upgrades.

Which new features or options in Oracle Database are you currently finding most valuable? As a big fan of database upgrade tasks, I find Oracle Multitenant to be one of the more remarkable options of Oracle Database 12c to prevent long downtimes in the upgrade process. I also really like the multiplatform capability of the Oracle Recovery Manager feature for backing up and restoring databases between different operating systems.

What’s your go-to Oracle reference book? Oracle Database 12c Backup and Recovery Survival Guide [Packt Publishing, 2013], written by my colleagues Francisco Munoz Alvarez and Aman Sharma. If you want to get the most information about backup and recovery in the least amount of time, this is the book.

How did you get started in IT? Even when I was a kid, I wanted to be an engineer—although I didn’t understand what that meant, of course. I have a bachelor’s degree in electrical engineering, so I guess I did make that choice early. Prior to its acquisition by Oracle, Hyperion decided to bring its worldwide support team to India. I got recruited and was among the first 60 employees to work in the India support office.

Oracle ACE Oracle ACE

Which new features in Oracle Applications are you currently finding most valuable? I’ve started looking at hybrid Oracle Essbase cubes. I’ve always loved the concept of a block storage option [BSO] cube acting like an aggregate storage option [ASO] cube. It gives you the combination of a powerful calculation-based BSO engine and a powerful aggregation-based ASO engine.

What technology has most changed your life? Online transaction processing. It certainly changed my career. It makes you think about how data can be tied to metadata, which helps you think multidimensionally.

What advice do you have about how to get into database administration? The database is so core and critical to most companies that they are very reluctant to take on someone completely new and let them loose. My advice would be to get another role in a company as a foot in the door, and then drive your career in the direction you want it to go once you’re in.

What’s the most common cause you see when IT projects go wrong? In my experience it’s bad communication that causes projects to fail. Teams need clear direction and roles and responsibilities. All of this needs to be well-communicated and understood so that everyone knows what’s expected of them, and when. This isn’t anything IT- or industry-specific—I think it’s the same in all sectors.
