      Enter password:

      ERROR:

      ORA-03134: Connections to this server version are no longer supported.

       

      Error Codes : ORA-03134

       

      We have set below parameter in sqlnet.ora file and restart listener.

       

      SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8

      SQLNET.ALLOWED_LOGON_VERSION_SERVER=8

      SQLNET.AUTHENTICATION_SERVICES=(NONE)

      NAMES.DIRECTORY_PATH=(TNSNAMES, ONAMES, HOSTNAME, EZCONNECT)

       

      But still we are facing this error :ORA-03134: Connections to this server version are no longer supported.
