I changed in init.ora remote_login_passwordfile from shared to exclusive and restarted the db. Then I changed the password of internal wiht help of oradim.
The result is that I can not connect with INTERNAL/pwd. The error message is ORA-01031 "insuficient privilegues".
The only possibility to connect is sys/pwd@db_name!
When I look up the "v$pwfile_users" -view no lines are selected.
I used orapwd to create a new passwordfile:
orapwd73 file= password= entries=10
The behavior did not change!
What have I to do to grant sysdba to sys or internal?
