IMHO;

- If you already didn't attend to Jonathan's 2 days seminar attending directly to 3 days seminar will be better,
- Jonathan does 1,5 hour sessions, when you think the content it is really too much for an average person, so we requested 45 minutes 2 separed sessions with 10 minutes short breaks between,
- if you are a junior dba or a developer you may get really lost in this seminar, I advice you to postpone to have this "one in a life time" feeling until you feel much more confident with Oracle database software to benefit at ends,
- come prepared to the last round-up session, JL will be sitting to answer your nasty Oracle problems just beside you, dont miss this opportunity, in our session we had the privlige to watch him go through an AWR report of a very busy 10gR1 database which was administered by one of the attanders.
