In Toad for Oracle 11, it is documented that this version will give you even more visibility into your Oracle environment, including Oracle options and packs.
I was trying to find out how to see Oracle options (not parameters) and packs that are installed in a database.
I can't find this info in Help, the KnowledgeBase or the release notes.
This statement is referring to the DB Health Check (There are three new checks in Configuration category) and HTML DB Doc Generator.
Both features report on Oracle feature usage.
