Connect system as sysdba error
Oracle 12c
I'm trying to connect from one Oracle server to another Oracle server using SQLPLUS and I'm facing an error with system account. Below some examples.
Inside server1, local database:
Sqlplus sys/password@orcldb as sysdba - connection successfully
Sqlplus system/password@orcldb as sysdba - connection successfully
From server2 to server1, using sqlplus:
Sqlplus sys/password@orcldb as sysdba - connection successfully
Sqlplus system/password@orcldb as sysdba - error, login denied
...and request me 3 attempts for user and password. I write the same system and then password and it works perfectly.
What should be the issue?
Thanks
