Hotsos Symposium Speaker – Jonathan Lewis

Mr. Lewis is a returning Hotsos Symposium presenter.


Jonathan Lewis

Jonathan Lewis is a freelance consultant with more than 20 years experience in using the Oracle database engine.

He specializes in design, trouble-shooting, and lecturing on the best use of the engine. Jonathan is a frequent speaker on the international circuit and has addressed audiences in more than 35 different countries in presentations lasting from 45 minutes to three solid days. He was a founding member of the Oak Table network, and one of the first individuals to be contacted by Oracle University for their "Celebrity Seminar" events.

His first book "Practical Oracle 8i" is still worth reading, despite being three generations behind the latest version, and his most recent book "Cost Based Oracle Fundamentals" still receives enthusiastic reviews. (Volume 2 - devoted to trouble-shooting - is on its way).

Presentation Title

Hints on Hints, Part 1
Hints on Hints, Part 2


Hints are very badly documented, and very difficult to use safely.

Even the hints which seem to be well-known and easily understood may be more subtle than you think.

This presentation offers you insight into why hints are sometimes needed, should generally be avoided, and must be treated with extreme caution.

There will be time at the end of this presentation for a general question and answer session on your favourite hints.

Presentation Materials

Presentation materials are available online to attendees only. Mr. Lewis' materials may be found on the Hotsos portal. Please use portal id to log in rather than email address.
