Overview
This page contains information about the tools and utilities I’ve written related to Oracle Database. While these tools are based on personal and academic research, I’ve found them to be useful enough to post for others to benefit from.

Most of these tools are released in binary form. As I have a limited number of systems to build on, a binary for your platform may not be available. If that is the case, please contact me privately. If the source code for a tool is not already provided, please do not ask me for it.

In addition to active session statistic collection, NAEVIUS provides the ability to persist historical session data over time, enabling a DBA to perform AWR-like snapshots and reporting.
