Description
The database data dictionary tables contain the data used by the database for database functions including database authentication and authorization as well as database configuration and control. By default, the parameter O7_DICTIONARY_ACCESSIBILITY is set to FALSE to prevent accounts with the privilege SELECT ANY TABLE from selecting the data dictionary tables. This setting protects the data dictionary from unintended access authorization by requiring full system privileges or direct table access permissions.
