I visited a two days course: Oracle Database 10g: Implementing Audit Vault
Everything was prepared, you were supposed only to start scripts and comment on the result. In real world everything was difference, not to mention that the course was on 10.2.3.0 and the latest (totally different) version is 10.2.3.2.
I would rather go with installing server, test database and agent and start building alerts, reports and so on.
My personal impressions are not so good for this product. I took main part in implementing it with big customer and in we started hitting bugs and problems. It has limited functionality, no integration with other products, hardcoded stuff and so on.
