RE: Patch installation frequency

We download and install monthly the current groups. We perform a full system save prior to applying them.

Subject: 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.

Thanks
