Oracle Database Discussions

While I was practicing chapter 6 a book on "hands-on oracle database 10 g express edition for windows" by Mr. Bobrowski forwarded by tom kyte, I like to be one those as well, lol, the living legend of oracle technology <page 225-226> , I got the following error while trying to insert the data manually
error ORA-02289: sequence does not exist

I also checked the sequence, it does exist ,
host-ids, db-ids, ap-ids all do exists

I am wondering my OS windows xp and however, I have entered AIX in host OS field and 5.2.0.0 in the hostos_version field and cpu=4
I kind do not understand this too since my pc running windows xp

any help would be appreciated since i couldn't go forward in my practice.

I e-mailed the author of the book (oracle Press) but no-reply so far, well I can understand that there is no money.
