Installation

The packages can be downloaded from Oracle Edelivery cloud and uploaded, you are searching for: V975837-01 package. In that ZIP file, there is one disk, so just upload it to the server and unzip it in a directory. Then you can start the installation via X-Terminal such as tigher-vncserver.
