How can the system administrator disable tenant database functionalities?

The option to use the Manage Blacklisted Parameter app is essential for disabling tenant database functionalities because it provides a structured way to manage and enforce parameter settings across the system. Administrators can specify which parameters should be blacklisted—meaning they cannot be used in the configuration of any tenant databases—thereby effectively disabling certain functionalities at a systematic level. This approach allows for more granular control over the operational capabilities of tenant databases.

Using the app is particularly beneficial because it offers a user-friendly interface and ensures that all changes are consistent and centrally managed, reducing the chances of misconfiguration that could arise from manual interventions. By implementing blacklisting through this app, the system administrator can swiftly enforce policies regarding tenant database functionalities without necessitating a database restart or modifying configuration files directly.

Other options, although they may lead to certain changes in functionality, do not specifically target the controlled and systematic disabling of tenant database features as effectively as the Manage Blacklisted Parameter app does. For instance, executing a database restart or modifying configuration files might not provide the precision in restricting functionalities that a methodical approach through blacklisting offers. Meanwhile, utilizing the SQL command line can allow for various direct manipulations, but it may not encompass a comprehensive method for managing parameters across the system as a whole
