Stuck with Oracle 9i
I had installed oracle 9i. This is my first time. I want to create a simple db. When i go to "Oracle Enterprise Manager Console" and add a database to the tree, i cannot access the db as i don't have a valid username/password.

After a lot of search, i found that, I have to create a new database repository. While i was creating, it needs USERNAME,Password,Service.
username : SYS/sys
Password : change_on_install
service  : <host>:<port>:<SID>
         : SYSDBA

But this is not working. I need a proper guidance to get out of this.
