Instance ID	ID of the database instance.
Host	After an instance ID is selected, an intranet IP address of a database is automatically matched. The domain name cannot be changed.
Port	After an instance ID is selected, a database port is automatically matched. The port cannot be changed.
Username	Username of the database. The database user must have permission to access data tables and metadata.
Password	Password of the database user.
