multiTenant

Specifies whether the to convert your DB instance from the single-tenant configuration to the multi-tenant configuration. This parameter is supported only for RDS for Oracle CDB instances.

During the conversion, RDS creates an initial tenant database and associates the DB name, master user name, character set, and national character set metadata with this database. The tags associated with the instance also propagate to the initial tenant database. You can add more tenant databases to your DB instance by using the CreateTenantDatabase operation.

The conversion to the multi-tenant configuration is permanent and irreversible, so you can't later convert back to the single-tenant configuration. When you specify this parameter, you must also specify ApplyImmediately.
