Connection sys as sysdba

Question

Hi,
Our DB is in 8.1.7.4 on Win 2003 server. If I connect
SQL> connect sys/mypassword@MYDB as sysdba
I have
ERROR:
ORA-01017: invalid username/password; logon denied
But if I issue :
SQL> connect sys@MYDB as sysdba
Enter password:
It would be OK :
Connected.
What is the problem ?
Thank for help.
In the two cases I entered the correct password and I'm sure of it.

Answer 1

By default, the SYS password on 8i is change_on_install, is it the one you used ?
Furthermore, the user/password used when you are conneting as sysdba doesn't matter :

SQL>Please, check the remote_login_passwordfile parameter value as I showed here above. Are you locally on the server or remote connection ?
Lastly, some unexpected behaviour can come on non-certified config (8i on W2003), but you already know that.
