Big one. It's best described in the concepts manual as well as in the DBA guide. To make long story short, you can modify SPFILE from sqlplus which is not possible with PFILe. SPFILE is "binary" (quotes are here because it's not very binary, just a little), while PFILE is a standard text file.

In %ORACLE_HOME%\DBS directory.

Nowhere. It doesn't search them. Locations of the control files are a mandatory parameter in the parameter file (PFILE and SPFILE) and control files contain, among other things, locations of all data, temporary and redo log files.

No problem. There is plenty of literature available on OTN (technet.oracle.com) as well as in the bookshops just across the wire, like http://www.bn.com (Barnes & Noble). Oracle has a site, maintained by the book writer of the year (no, it's not Cary Millsap, it's like NFL, the best team never wins. I have quite a few funny stories about NFL and being dead certain that I know which team will win, but this is not an NFL mailing list). The site is http://asktom.oracle.com. It's maintained by Tom Kyte who answers as many questions as humanly possible. Not all answers are useful, but all are factually correct. The good books to read are probably
1) Oracle9i DBA Handbook by Kevin Loney and Marlene Theriault (don't shoot, Rachel, it's French!)
2) Expert 1-on-1 , Tom Kyte
3) Practical Oracle 8i (one of the best DBA books ever written, even for a beginner, pertinent for version 9i
as well), written by J. Lewis
4) Oracle Administratiion and Management by M. Ault (don't buy Oracle8i Admin. and Mgmt. as it is obsolete.
the second edition is much better)
There are other good books, which are not, in my opinion, suitable for a beginner.
1) Cary Millsap: Optimizing Oracle Performance (excellent book) 2) Gaja V., Kirti Deshpande, John Kostelac 101 Oracle Performance Tuning (really great book) 3) Guy Harrison Oracle SQL High Performance Tuning
The mandatory parts of the DBA arsenal are also Robert Freeman's RMAN book, Don Burleson's Statspack book and last but least, Andy Duncan, Jared Still: Perl for Oracle DBAs (just for the lovers of the pathologically eclectic rubish lister)

It's not your fault. You may want to try with Linux, though.
