How did you get started in IT? I left university with a degree in genetics and zoology, but my interest in home computers as a teenager and some programming work during my degree was enough for the UK National Health Service to take a chance on me. On the patient administration software team, we used a “relational data reporting tool” that was so awful no one else wanted to touch it. Somehow I got it to work, learned about this SQL language it used, and taught others how to use it. Not long after that, Oracle UK was looking for people who knew healthcare systems and relational databases, and I joined them.

What’s your favorite tool on the job? My favorite Oracle tool is Automatic Workload Repository—both the graphical front end provided by Oracle Enterprise Manager and the raw data held in the underlying tables.

What’s your go-to Oracle reference book? Over the last couple of years I’ve found my copy of Expert Oracle Exadata by Kerry Osborne, Randy Johnson, and Tanel Põder [Apress, 2011] invaluable. When I do my introductory presentations on Oracle Exadata, I always tell people to get a copy of this book.

How are you using cloud computing in your work these days? I use cloud computing for testing—for example with Oracle Enterprise Manager 12c. We have a private cloud solution with an 8-node Oracle Real Application Clusters [Oracle RAC] cluster with many different Oracle databases. This Oracle RAC cluster is monitored with Oracle Enterprise Manager 12c. For our test systems, we’ve built the private cloud solution with Oracle VM 3.

How are you using mobile computing? I administer the databases with my mobile devices—specifically, monitoring Oracle databases with my iPhone and the mobile version of Oracle Enterprise Manager Cloud Control.

How are you using social media? As president of the DOAG [the German Oracle Users Group] Database Community and a member of the DOAG management team, I use many social networks—Facebook, LinkedIn, XING, Oracle Mix, SlideShare—to be in contact with Oracle DBAs, Oracle ACEs, and Oracle user group members worldwide.

What’s your favorite tool on the job? Oracle Recovery Manager [Oracle RMAN]. It allows me to perform backup, recovery, and maintenance activities; SET NEWNAME offers the flexibility to set the new name using a single command for the entire database or tablespace; and Data Recovery Advisor automatically determines repair options and performs repairs.

Which Oracle Database options are you currently finding most valuable? Oracle Real Application Clusters [Oracle RAC] has many exciting capabilities, such as zero downtime for patching and Oracle Automatic Storage Management Cluster File System, a robust file system that can expand and contract without any downtime.

What technology has most changed your life? Definitely Oracle RAC. Since completing my Oracle RAC expert certification, I’ve started sharing my knowledge and experience through my Website, oracleracexpert.com, and through writing articles for major Websites and publications.
