O7_DICTIONARY_ACCESSIBILITY          boolean     FALSE

 

With this parameter in False, it will not allow accessing anyone dictionary views, tables objects in SYS schema without SYSDBA/SYSOPER roles. O7_DICTIONARY_ACCESSIBILITY controls restrictions on SYSTEM privileges. If the parameter is set to true, access to objects in the SYS schema is allowed (Oracle7 behavior). The default setting of false ensures that system privileges that allow access to objects in “any schema” do not allow access to objects in the SYS schema.
