As long as it's in ARCHIVELOG MODE the logs will need to be archived - so it should be very exceptional to stop the archiving process (which normally should be done automatically: ALTER SYSTEM ARCHIVE LOG START; ) Yes, you can stop the process, but WHY?

OK: What are you really trying to do? What is your objective?
