DO3685-ORACLE11 - The Oracle O7_DICTIONARY_ACCESSIBILITY parameter should be set to FALSE - 'O7_dictionary_accessibility = false'

Information

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.

Solution

Disable O7_dictionary_accessibility to restrict access to system tables to users granted privileges to access objects owned by all users.

From SQL*Plus:

alter system set O7_dictionary_accessibility = FALSE scope = spfile;

The above SQL*Plus command will set the parameter to take effect at next system startup.
