Just curious. Someone asked about an undocumented view that lists all the errors and I followed the train of thought. Oracle puts parameters that are in progress, or about to be desupported as undocumented parameters. Some of them are used by Technical Support I think. I was wondering if they do the same thing with data dictionary views, or if that is pretty much fixed and they introduce them all suddenly when a new version is released. They do introduce new views from version to version, I was thinking maybe precursors of those might exist in the previous version. Doesn't sound like it. It makes sense that they wouldn't -- after all, I imagine there is a (slight) performance hit involved in maintaining data dictionary views. They probably lump them all into the next version's beta and test them there through their partners. I know about the base tables and X$ tables.
