"Every problem is a database problem until the DBA proves otherwise." Plato, probably. Whether conducting a proactive review of a database or firefighting an outage or performance issue, most of my work as a consultant revolves around a handful of free, open-source and Oracle-provided utilities. In this session, I'll share these tools and show how I use them to find and solve database (and non-database) problems. The first part of the session focuses on reactive tools that will help you quickly isolate, contain, and extinguish fires. In the second, we'll dive into proactive and diagnostic solutions, demonstrating how to use them to catch and repair problematic configurations before they cause problems!
