Hosting Controller provides interface for web admin users to create System DSN on the Server and perform operations on it. This is useful because the web administrators frequently require the operations of DSN creation when a specific database related web site is uploaded and DSN needs to be created for the database.
Before trying to create DSN, database must be uploaded to \db folder of the user for which DSN has to be created. The \db folder is created when website is created for the specific web admin. You may access the \db folder either by doing FTP to the web site or through Directory option present in control panel.
