Hello Kevin, I have seen many good posts in reply to your situation already. File-sizing, (and therefore disk IO) is a key/critical area.
What kind of file systems do you have? How much memory & swap space do you have? What are the Virtual Memory AIX tuning parameters set to? IBM Hardware - AIX support and IBM U2 support - are all the same company, and they can't find it? Please give us the system configuration information so we can all develop a more clear picture of what you're running there. Is this system a recent OS upgrade from AIX 4.X? Any new or different hardare added or subtracted? Any other changes that may be noteworthy? The way you discuss memory, page faulting, and very high disk IO, I would make sure they verify each of your uvconfig parameters, and kernel system tunable parameters, and make sure you have more than ample swap space, and a large /tmp mounted file system space with fast striped disk sub-system underneath. One tool that will help map out exactly what is going on, and therefore provide a road map on how to address/resolve these issues, and then prove that these issues are indeed resolved, would be the DPMonitor. DPMonitor is available on the internet and has a free 10 day evaluation license available that will allow you to track system-wide parameters and performance metrics that will provide a very clear picture as to what is happening. Check it out at www.deltek.us. This tool has been used on AIX 5.1, on small single processor configurations, up through very large systems, 16 & 32 processor systems. Performance Agent runs on the AIX Application Server. Extremely low overhead Agent. Performance Explorer runs on a Windows Workstation. Well worth the free 10 day evaluation license.
