Once you disable a loader connection and log out of the Repository Manager, the loader connection is no longer listed in the Loader Connection’s List View page. To enable the connection, you must go to the tree view and search for disabled loader connections.
To search for and enable a loader connection from the tree view:
In the Repository Manager’s Navigation View, select Loader Connections.
Right click and select Disabled Loader Connections. The Loader Connections List View opens, showing all disabled loader connections for this repository server.
Select the connection you want to enable.
Right-click and select Enable from the drop-down menu option.
