Part 7 of our ongoing series on DBA Rules of Thumb is a short one on being accessible and approachable... in other words, Don't Be a Hermit!
Sometimes DBAs are viewed as the "curmudgeon in the corner" -- you know the type, don't bother "Neil," he'll just yell at you and call you stupid. Don't be like Neil!
Instead, develop a good working relationship with the application developers. Don’t isolate yourself in your own little DBA corner of the world. The more you learn about what the applications do and the application requirements, the better you can adjust and tune the databases to support those applications.
A DBA should be accessible. Don’t be one of those DBAs whom everyone is afraid to approach. The more you are valued for your expertise and availability, the more valuable you are to your company.
