From the Help menu, on RED's main top bar, users can select the Reset Meta Database Connections option.
This option disconnects and frees most connections that RED has to any existing ODBC connections. This option can be useful for users that are already connected to existing ODBC sources but want to alter the credentials used.
When this option is used, RED attempts to release most existing ODBC connections so the next time an ODBC Connection is used, RED will attempt to reestablish a link.
Note
At this stage, not all RED connections are handled via this mechanism and therefore not all connections will be reset when this option is used.
To reset meta database connections, click the Help menu in the main top bar and then click Reset Meta Database Connections.
Click OK on the following reset connection dialogs.
