Enabling ARCHIVELOG on windows

Question

Hi I'm on Oracle 10.2.0.4.0 running on MS Windows and following the instructions to put my database (ORCL) in ARCHIVELOG mode.
It sounds like I need to perform the following to do this:
ALTER SYSTEM SET log_archive_dest_1='LOCATION=E:\oracle\admin\ORCL\arch' SCOPE=SPFILE;
SHUTDOWN IMMEDIATE
STARTUP MOUNT
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;
ARCHIVE LOG LIST
SHUTDOWN IMMEDIATE
STARTUP
So this is how far I've gotten...
From cmd.exe:
C:\>set local=ORCL
C:\>sqlplus /nolog
SQL*Plus: Release 10.2.0.4.0 - Production on Tue Dec 8 20:21:18 2009
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORA-24324: service handle not initialized
ORA-01041: internal error. hostdef extension doesn't exist
What am I missing here? Sorry I don't usually work with Oracle on Windows.
Thanks in advance for any help.
