1- Why did you choose to specialize in Oracle databases?
Before I was a DBA, in my first IT job after college, I worked with databases as a developer and the application
environment was mostly Oracle. This provided me with incentive to learn Oracle.
2- What made you specialize in Oracle Real Application Clusters and Linux systems?
Years ago, when I first began working as an Oracle DBA, I had to work on an Oracle 7 OPS (Oracle Parallel Server) on SunOS UNIX platform. This was the precursor to Oracle RAC and I enjoyed the challenges. I continued working with RAC as the product matured and it became a focus in my database forte. Since I had a solid network and storage background before I was an Oracle DBA, it made sense since a good Oracle RAC DBA must know these things in addition to Oracle. As for Linux, I worked mostly over past decade on UNIX systems with Oracle and with the evolution of Linux, it made sense as Oracle has shifted from developing on Sun Solaris to Linux platform.
3- Do you still remember the first day in your first job?
Yes, in college, to pay for school, I worked for the computer lab on campus. I had to enter thousands of pages of data entry in a mainframe computer! It was horrible but my first paying tech job before graduation so I accepted the drudgery and never complained. My boss was appreciative and let me train on databases as result! I learned SAS, UNIX, and Oracle.
