Oracle: Tables and Views missing from the all_objects dictionary I have a couple of database instances that are having the curious issue where tables and views do not show up in the all_objects dictionary which is causing some issue with certain schema viewing applications. Not all are missing, but there is only like a dozen of the 130 or so tables/views that are in the schema. If you query all_tables or all_views, they all show up just fine. If you select/update/delete with those tables, it works fine.

Any one know of what types of things I should be looking at that would cause this?

BTW, I am not the DB administrator to this DB, I'm just trying to figure this out for our client. I don't have full access to the DB.
I tracked it down to an SCHEMA.ALL_OBJECTS view attached to the schema that was restricting the tables rather than using the SYS.ALL_OBJECTS view.
