Hello.
Os is Red Hat Enterprise Linux Server release 7.4
DB is 12.2.0.1
I intsalled Oracle 12.2.0.1 binaries on the test server, appplied patches 27105253 and 27001739.
I have taken an rman cold buckup that I restored on the test server.
Connect as sys as sysdba on the local server works but any attempt with any other username locally or remotely fails with ORA-01017:Invalid Username/Password.
I changed the password of a user but still.
Even create a new user
sqlplus / as sysdba
