Can't see system information on new DATABASE

Hi

I've created a new database, alongside the default 'ora' created at installation  (Oracle 7.0.13). I can create things, look at them, create users, the 2nd db  starts OK, everything is lovely, EXCEPT I can't see any of the tables which  give me information about the new db. It's my understanding that CREATE  DATABASE should have done all this. I should add that the first attempt at  creating the database failed due to a badly configured rollback_segment line in  the parameter file, but I deleted all the files, and recreated the db with no  errors.

Any ideas? Example follows. Sorry if this is a FAQ, but I have had singular  unsuccess getting at the FTP site.
