Re: ORA-01031: insufficient privileges when conn sys/password as sysdba

Any idea? It is newly copied db.
I can connect localy. I get the error when I try to connect as sys remotely. All other user can connect okay, except sys. Any idea?

Thanks!

Also remote_login_passwordfile=NONE

how on earth you expect sysdba/sysoper working when you have this?

remote_login_passwordfile=NONE

Check
1. is service properly created in tnsnames.ora file
2. r u using service name while connecting like sys/pass@ser1 as sysdba
3. if os is windows then make SQLNET.authentication_services=(NTS)

possible Suggestions
1. Make remote operating system user, the member of oradba group at database server.
