AIX Virtual Memory Management: Tuning Recommendations

I recently had to deal with a system which had a lot of RAM available but was still paging a lot. It was running AIX 5.3. Eventually we found note 973227 which gave us the correct parameters for tuning SAP virtual memory. Also look at note 1157425 which gives some details on configuring the correct amount of AIO processes for AIX.
