This is an article showing how to update the SSH keys on the Oracle Database Cloud instance.

One thing I realized is that through the current Oracle Database Cloud User Interface I’m able to add new SSH keys, but I don’t have the possibility to remove old ones so I checked other alternatives on how to do it directly from the Operating System.


With Putty I’m able to connect to the Operating System using the SSH key generated by the special puttygen.exe tool. There I’m able to access the following file:

After saving the file the connections that use the old keys will not work anymore.
