To install the Oracle Developer Studio software on an NFS-mounted file system, you must run the installer on a system that meets the Oracle Developer Studio system requirements regardless of where the NFS partition is mounted. See System Requirements in Oracle Developer Studio 12.6: Release Notes.
In the following procedure, the server is the machine with the physical disk on which the installed software will reside, and the client is the machine on which you run the installer and which NFS-mounts the shared file system from the server.
This procedure describes how to share a file system to a client machine where you will run the installer.
share -F nfs -o root=client-machine,rw filesystem
mount server-machine:filesystem installation-directory
