RDBMS Forensics: Troubleshooting Errors using ASH (Active Session History) by Tim Gorman
Topic: Indiana Oracle Users Group Files
Owner: Gary Wicke
Arthur C. Clarke wrote that "any sufficiently advanced technology is indistinguishable from magic." That is true and it sometimes makes troubleshooting seem like art. But it is not art; it is process and this presentation uses two case studies on resolving the ORA-03136 "connection lost" error to demonstrate that process and to show how components such as ASH, typically thought of as performance tuning tools for DBAs, are also useful diagnostic tools for everyone, particularly developers.
