connect to Oracle Cloud from SQLPlus and Instant Client I want to try to connect with SQLPlus to Oracle Cloud.

for regular oracle I can connect from remote machine as follows:

IP = 1.2.3.4
PORT = 1521 
ServiceName = "ORCL1"
Username = "username"
Password = "password";

sqlplus username/password@1.2.3.4:1521/ORCL1


Is it possible to connect also to oracle cloud in a similar way? 

Next step is to connect Oracle Instant Client to Oracle Cloud, but I want to do so without any installation (except copy of DLLs, but without need of editing 'tnsnames.ora' etc.).

I use occi interface like this:

IP = 1.2.3.4
PORT = 1521 
ServiceName = "ORCL1"
Username = "username"
Password = "password";

env-&gt;createConnection("username", "password", "1.2.3.4:1521/ORCL1");


Can I connect in the same way (or how to connect) to Oracle Cloud?
Assuming your Oracle database on Oracle cloud then you can connect to SQPLUS over SSH:


connect to oracle cloud service
click on the name of the deployment you want to connect to
copy public IP address
switch to Linux command prombt
check your and confirm the private public key for your deployment exist
run ssh -i ua_key_openssh oracle@IPADDRESS_YOU_GOT_FROM_POINT3
execute sqlplus command 
enter username\password
