Oracle Privledge.

Question

I am seeing something very unusual. I created a new schema tester and granted tester read access to the tables owner by another schema (FRED). When i log in as tester and query all_tables, I should only see the tables owned by FRED. However, i am seeing tables owned by FRED and dba tables (SYS, SYSTEM, etc). Any ideas? This does not happen in our development envrionment.

Answer 1

I didn't grant any other privledge to tester. I just created another schema and granted only CREATE SESSION. When i logged in using this new schema, i can see the followign tables when i query all_tables.
