Hi Denis
We are a 24 by 7 shop
We have a quarterly maintenance - on a weekend and if we attempt to do anything outside of that maintenance schedule - it will HAVE to be of something REALLY important
We have done that - probably twice in the 15 years I have been working here

Any patches (cumulative or otherwise) are applied to our development system, once they are at least 3 months old
Then 3 months later, those same patches are applied to our production system

I am assuming that the auditors are wanting the patches applied more frequently than what you are doing
You don't say what your schedule is for applying patches and if you are a 24 by 7 shop

Subject: [EXTERNAL] Patch installation frequency

Hello all,

Our internal auditors are on my back. They want me to install patches (PTF ...) on the system i with the same frequency as we do on our Windows farm.
I told them that these are 2 different animals and that I am not compromising the system by not installing every cum package as soon as they come out.
But, since I am not a 200$/hours consultant, I have little credibility regarding this.

I am looking for official or semi official (best practice) guideline for patch management frequency.

Unfortunately, opinion given on this list wont cut it. I am looking for web pages, PDF document or something the like.

I did some search on IBM site and found nothing.

Any help will be appreciated.
