To change the following parameter, you have to update the init.ora first and re-start the db. Right?

NAME VALUE ISSES_MODI ISSYS_MODI
------------------ ---------- ---------- ----------
log_archive_start FALSE FALSE FALSE


Is this the only way to change this parameter "permanently"? I just wonder if you can use SPFILE to do it? If not, it looks like you cannot 100% rely on SPFILE in 9i. You still need to have a init file updated all the time. Am I right?
