HELP: Problem creating a new database in Oracle 9i

Question

I am having difficulty in creating a new database in Oracle 9i, on Windows 2000. I would be obliged if somebody can go through the posting below and guide me as to what mistake I am making or what is the source of the problem:
I reproduce the steps taken by me.
I have decide the database to be called Mydb. I have made the following directories:
-- d:\mydb
-- d:\mydb\data
-- d:\mydb\control
-- d:\mydb\log
-- d:\mydb\bdump
-- d:\mydb\cdump
-- d:\mydb\udump
-- d:\mydb\archive
-- d:\mydb\pfile
-- d:\mydb\scripts
-- d:\mydb\exp
I copied the initoracle.ora file to d:\mydb\pfile\initmydb.ora, and made the following changes to it:
-- db_name = mydb
-- instance_name = mydb
-- control_files = ("d:\mydb\control\control01.ctl")
-- background_dump_dest = d:\mydb\bdump
-- core_dump_dest = d:\mydb\cdump
-- user_dump_dest = d:\mydb\udump
-- remote_login_passwordfile = exclusive
Also, I created a text file called d:\Oracle\Ora90\DATABASE\initmydb.ora with the following contents:
ifile=d:\mydb\pfile\initmydb.ora
At DOS prompt, I run the following command:
set oracle_sid=mydb
I run the ORAPWD utility to create internal password file at the command prompt.
d:
cd \oracle\ora90\database
orapwd file=pwdmydb.ora password=panther entries=25
I create a Windows service for the database as follows:
oradim -new -sid mydb -startmode a -pfile d:\mydb\pfile\initmydb.ora
I get connected:
sqlplusw /nolog
connect sys/change_on_install as sysdba
startup nomount # pfile=d:\mydb\pfile\initmydb.ora
create database mydb
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXDATAFILES 100
datafile 'd:\mydb\data\system.dbf' size 325m REUSE
AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED
undo tablespace undotbs datafile 'd:\mydb\data\undo01.dbf' size
200m reuse
AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED
default temporary tablespace temptbs
CHARACTER SET WE8MSWIN1252
NATIONAL CHARACTER SET AL16UTF16
logfile group 1 ('d:\mydb\log\log1.log') size 1m,
group 2 ('d:\mydb\log\log2.log') size 1m,
group 3 ('d:\mydb\log\log3.log') size 1m;
Now I get the following error:
create database mydb
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced
The data files, control file, redo log files are all created. But the above error comes, and I am unable to start the database. What is the reason?
Thanks in anticipation.

Hi DENIS,
I have executed the following commands (which are in a script file),
1. sqlplus /nolog
2. connect sys/change_on_install as sysdba
3. create database ...
4. ...
When I execute the 3rd command, I get an error message as "ORACLE TERMINATED FORCED" and it will end the session. So when the next set of commands in the script are executed, I got the error saying "DATABASE NOT OPEN".
How to rectify this problem.
Thanks in advance,
Kiran
