Oracle 10g R2 for Windows ignores init.ora and registry values

Question

Hello,
I have a strange issue. I try to set some parameters for Oracle but it doesn't seem to work.
Here the story:
I created the DB with the DBCA under windows and set my init parameter at frist creation with 3 important values:
OS_AUTHENT_PREFIX = ""
REMOTE_OS_AUTHENT=TRUE
remote_login_passwordfile=EXCLUSIVE
this values are in the Registry and the init.ora and the init.ora.7192011143454 in ORAHOME_DB/scripts and pfile
I've now changed these parameters in the init.ora and registry to:
OS_AUTHENT_PREFIX = ""
REMOTE_OS_AUTHENT=FALSE
remote_login_passwordfile=EXCLUSIVE
and restarted the whole system - after the restart I checked the value for REMOTE_OS_AUTHENT:
show parameter remote_os_authent
NAME TYPE VALUE
remote_os_authent boolean TRUE
It keeps true. But why it keeps true why I can't change this value anymore after the DBCA?
Do I miss something?
Thanks

Answer 1

show parameter spfile;
NAME TYPE VALUE
spfile string C:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\SPFILEMACSCURR.ORA
NAME TYPE VALUE
I have created a new spfile from my init.ora with:
create spfile='C:\oracle\product..toMyInstanceDbs\ioglnx.ora' from pfile='C:\pathToPfile\DBHOME\scripts\init.ora'
So the problems as it seem to me to instrcut oracle to use my new spfile...in Windows.
