Oracle8i- access via Console;access to DBAStudio

Hi.
We have here Oracle8i, running Oracle Clinical database.

When I try Start>Progs>Oracle>Database Admin>DBAStudio, it just hangs forever.

When I try Start>Programs>DatabaseAdmin>EM>Console, it asks for Administrator login and password and Management Server.

I cannot figure out how to get into the OMS.
The value must be in initora file which I have located.
Which values do I need to put in this login box to gain access?

Could I have components missing?

I ask because I cannot see Instance Manager in Oracle 8i.
Please let me know what I should have after installing Oracle8i so that I can check if I have all the pieces of the puzzle in the first place.

Thanks.
