Chapter 8: Analyzing Server Performance
The separation of tasks between a SA and a DBA is often blurred. This blurring of roles can be especially true in small shops in which you wear multiple hats. Even in large organizations with established roles and responsibilities, you’ll still experience an occasional “all-hands-on-deck” fire drill in which you’re expected to troubleshoot server issues. In these scenarios, you must be familiar with the OS commands used to extract information from the server. An expert DBA does not diagnose database problems in a vacuum; you have to be server-savvy.
