Problems with creating new database

I am new to oracle and I have been working to create a new database using oracle 8 under NT4.0.
I used the tool - Database Assistant and created a new database called TST. I then had to manually modify the listener.ora and manually create a Service to the new SID (also called TST).

Now I tried to go into the enterprise manager as "system" using the new service and I get an error in the Oracle Repository Manager:

XP-07016: A database error has occurred: insert into smp_rep_version (c_component, c_current_version, c_unused) values (:1,:2,'')
ORA-01552: cannot use system rollback segment for non-system tablespace 'USR' What do I need to do? Shouldn't the utiltiy that created the database take care of this? What is the best way to manage/create a database. Oracel 8 tools do not seem to be integrated/work properly. If thats the case then whats the best way to manage the database, although I may be using the tools wrong.

Thanks,
Haresh Assumal
