John thanks for the perspective and questions.
May 19: I shut down the box. IBM Installed the memory, then I booted up the box. Nmon reports show available memory hovered around 33-35GB.
I have CPU/memory monitoring data from nmon each hour 24/7/365. This is how I was able to see that on May 26 through today available memory went from 35GB all the way down to 2.5 GB.
My attachement is currently what is typical as far as how much memory the application is using. You can see that there is no paging. The box is not breaking a sweat.
A caveat. We are still running AIX 5.1 ML04. In a week we will upgrade to AIX 5.3 TL04. This series of downtimes were set to upgrade harware, Oracle, AIX, MQ, CPU/memory.
