Home -> Community -> Mailing Lists -> Oracle-L -> RE: Undocumented data dictionary views
Boivin,
I think this is very different types of things.
One is C code, which is compiled, and no one have access to it source.
Then Oracle can introduce hidden parameters, which affect code behaviour.
Second - SQL code, which can be accessed normally. And easily dropped then
code goes to production. Is there any usefulness from view, which give
information about unrealized features?

Subject: RE: Undocumented data dictionary views
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.
Pat.
