You can look into what specific filesets are part of the APAR. As a rule we have a sandbox, dev, qa, training, and production environment. Fixes are rolled out in that order so that if a problem does occur it is recognized early on before it is to visible. We also always install in APPLIED mode so that it can be backed out quickly. In the past month we had an issue where the installation of a particular 5.2 APAR caused our Veritas backups through the gigabit ethernet interface to slow to a crawl. We were able to quickly back out and the impact was minimal. We eventually resolved it and started the rollout again.
Unless a specific problem in our environment is identified along with an APAR that corrects the problem we usually just install fixes with a whole maintenance level install.

Hi *,
Can someone give me a view of hoe to analyse the impact of an APAR
that would be applied on a system. I understand that this differs from each
application that is running on the server. But in general how do we start
analysing the impact, it would be great if someone can share any of the
existing check lists which you use.
TIA
Praveen.K
