Create development database on local workstation 1

[evergrean100]

I have an Oracle 9i local database on my local Windows XP workstation that is for local development only.
Now I am trying to create a database and using OEM Database Configuration Assistant.
I put in FirstDB for the Global Database Name and put in FirstDB for the SID.

I completed the wizard and set up my tnsnames.ora file with the SID and hostname. Then I tried to connect using OEM and it says:
ORA-12545:Connect failed because target host or object does not exist.

Should I put in localhost or 127.0.0.1 for my Global Database Name?

I assume I connect as Sys or System and the password I created after right after creating the database.
I also dont know how or where to manipulate listener or do I even have to do anything with listener?

Please advise how I can get this to work?

Did you check the listener is up and running (Check the services in Control panel-> Administrative options)?

Thanks, listener was not running and now it works.
