1.203 O7_DICTIONARY_ACCESSIBILITY

If the parameter is set to true, access to objects in the SYS schema is allowed (Oracle7 behavior). The false setting ensures that system privileges that allow access to objects in "any schema" do not allow access to objects in the SYS schema.

For example, if O7_DICTIONARY_ACCESSIBILITY is set to false, then the SELECT ANY TABLE privilege allows access to views or tables in any schema except the SYS schema (data dictionary tables cannot be accessed). If O7_DICTIONARY_ACCESSIBILITY is set to false, then to access objects in the SYS schema, the user should have SELECT ANY DICTIONARY system privilege or the user should have been granted SELECT object privilege on the specific objects. The system privilege EXECUTE ANY PROCEDURE allows access on the procedures in any schema except the SYS schema.

If this parameter is set to false and you need to access objects in the SYS schema, then you must be granted explicit object privileges. The following roles, which can be granted to the database administrator, also allow access to dictionary objects:

• SELECT_CATALOG_ROLE

• EXECUTE_CATALOG_ROLE
