The first time I used it, Hotsos Profiler helped me reduce the run time of one query from 6½ hours to less than 11 seconds.

Hotsos Product Line

The Hotsos product line includes the following best-in-class software:

Hotsos Profiler

Find out what's taking so long. With very little training, Hotsos Profiler helps database administrators solve even the most persistent performance problems, no matter where in the system they occur. Our flagship product, Hotsos Profiler is industrial strength software used by some of the largest companies in the world.


Find performance problems before your users do. Laredo helps software developers and database administrators keep changes from accidentally ruining system performance. You should never create or drop an index, change an instance parameter, or even gather statistics without using Laredo.

How We're Different

Traditional Oracle tuning tools automate old methods that haven't changed much since Oracle release 5. The problem is, those methods are remarkably inefficient. Often, even with the most expensive tools available, Oracle system owners suffer with performance problems for months without being able to find the root cause.

Finally, something new...

Hotsos automates an efficient new performance improvement method that enables Hotsos-trained analysts to do better performance work than they've ever imagined, at dramatically reduced labor costs and with very little training.

Frequently Asked Questions

What happened to Sparky?

Sparky was a free program that made trace file collection into a point and click operation for Oracle versions 7,  8, and 9. It became something of a maintenance nightmare for us because it wasn't designed to work with connection pooling architectures or Oracle Database 10g, so we retired it. It is no longer available.
