Rich Leick was brought into a major insurance company as a consultant to help them with managing defects and bugs in their core underwriting application. One major problem Rich noticed was that support developers had little-to-no information about the problems they were assigned to fixed: the application provided no logging and all of the error messages simply read "An error occurred. Please try again."

After Rich spent a few weeks adding copious amounts of logging, tracing, and error handling code to the system, the developers were thrilled. They finally had some direction to go when they were assigned a bug. Still, there was one thing that struck Rich as rather odd: the database was throwing lots and lots of "divide by zero" errors.

A little bit of investigation led Rich to the core of the problem, the ABORT_PROCEDURE procedure. Rather than throwing and handling exceptions within the procedures, the original developers decided to use this instead ...
