I have install oracle9i but I am not able to connect to sys account it is giving error "Invalid User name and Password"
I am assuming the password of sys is same i.e change_on_install but I am not able to login form this password also.
Thanks in advance
You can try following stuff.
1)Check the connection string
2) If you have Oracle on Wondows 2000/NT, did you give any password while creating the service (oradim -password )
as this will change the password
try to connect as
host: ORCL as sysdba
or connect sys/change_on_install@ORCL as sysdba
As sys, make sure you use the appropiate connect string. Or you can connect as system/manager using the sysdba role.
and if you were trying sqlplus internal, it wont work anymore and internal no longer exists
