The Importance of Peripheral DBA Skills

The DBA Skills Gap

In going to different companies every month I am consistently seeing a DBA skills gap in the peripheral areas of being a DBA. In the old days, a DBA that understood the operating system, networking and the development environment was a pretty complete DBA. Especially since in the old days, DBAs came from the development ranks and could support developers. In today's complex database environments, there is a definite skills gap in DBAs understanding the environments around databases. DBAs don't need to be experts in these areas, but should at least be comfortable in some of the areas surrounding databases:
  • Operating system.
  • Basic networking knowledge.
  • Storage management.
  • RAID levels.
  • Striping and mirroring concepts.
  • Middle-tier fundamentals (Application Servers, connection pooling, caching, connection best practices from Java, .NET, PHP, etc).
  • J2EE environments (Web Services, WSDL, SOA, BPEL, ...).
  • XML.
DBAs with peripheral skills in some of these areas are worth their weight in gold. With the complexity of database management it is getting harder and harder for new DBAs to have strong DBA skills and peripheral skills of the environment surrounding the database.

I'm unsure how a DBA could get by without a pretty good bit of the knowledge on your list. Then again, I can't remember how many times I've had to explain why raid 1+0 is better than 0+1 to DBAs and system administrators alike.

Hard Drives are getting bigger, but the issues of crashing still arise.

    The Trubix Blog is focused on discussions on strategic directions in database technology and the challenges Oracle technologists are addressing today and in the future. This site will focus on issues and challenges of database management that cannot be resolved with a code snippet. There are already a lot of great websites out there with tons of code samples. We would like to facilitate more discussions on issues Oracle technologists are dealing with today that a quick search on the Internet cannot solve. There will also be a group of recognized industry leaders that will also participate in this blog. This blog is an extension of the Tim Tam Group, an international group of industry leaders that meet once a year to discuss strategic directions in the industry.
