How can I import a local dmp file to an oracle database on the remote host?

You can upload files remotely and then import them. Of course, you can also connect to a remote database through the network for import, but the efficiency may be quite poor.
Check whether the local and remote database versions can be exported.
 
How Does oracle import my local data to a remote oracle Server?

1. Export the local database to the dmp file, and then upload the exported file to the server for import.
2. Create a local dblink and use SQL statements to insert local data to the server database.
