This is why my preferred method of installing service is to clone my target and distribution zones, and apply the service to the clone. When it looks like the APPLY was successful, I'd IPL (for z/OS) or otherwise activate (for other kinds of products). When I'm satisfied that the old zones are no longer needed, I'd delete the old zones. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
