I'm trying to make a SQLplus connection to a remote Oracle DB following this documentation and it's failing at this step sqlplus username/password@//dbhost:1521/SID
with the error:
ORA-01017: invalid username/password; logon denied.
I'm using the following syntax:
sqlplus username/password@//x.x.x.x:1521/SID
I know the DB is reachable and my passwords are correct (verified with Oracle SQL dev). What am I doing wrong?
