We would never take the approach you mentioned. I would hate to explain to my management that we took an outage due to the fact we had not put on a fix that had been available for some time. Our philosophy is to apply Quarterly RSU -1 regularly each quarter plus any vulnerability fixes identified . This doesn't mean we achieve it every quarter due to other workloads but that what we try and do.

But no RSU maintenance. Instead of maintenance, the plan is to just reinstall z/OS and all related products anytime they want to refresh the maintenance level, including in between z/OS upgrades. When it was suggested that a reinstall requires so much more effort and risk compared to RSU maintenance, the response was "it doesn't really and that a lot of shops do it that way". Sure there are some shops that never put on maintenance in-between upgrades, except the PTFs required for a problem. Are there other places that regularly reinstall everything instead of putting on maintenance? Are there benefits to this approach? Would this approach bother you? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ________________________________ Warning: All e-mail sent to this address will be received by the corporate e-mail system, and is subject to archival and review by someone other than the recipient.
