Oracle error: "ORA-12560: TNS: protocol adapter error."
Hello! Got an Oracle 11g home computer. I'm launching SQL Plus and I'm injecting a default user. Login: su, password is empty. There's a mistake in the entrance: "ERROR: ORA-12560: TNS: protocol adapter error." Help me find where the passwords and logic of Oracle users are built.
- You haven't written anything about whether you've created an O.D. or not.
- Check if TNS listener: tnsping
- The simplest way to check whether the OBD is raised correctly or not
telnet localhost 1521♪
- Start a service.msc and visually check the state of services called Oracle* service, in specialty
ORACLE_SID- that's the name of your OBD instas. Usually the oracle creates this variable automatically. You can check: echo
%ORACLE_SID%(in principle, you should know her - once you've had the OBD.
