Good Day Everyone,
Just wonder anyone has encounter AIX 6.1 Memory Performance issues ? What I have in my current scenario is we have 3 datastage servers (Segregate server and EE jobs - for those who know Datastage achitect) and 2 db servers(running HA to load balance 4 nodes partitions for each server). From our observation, after ETL jobs run for quite sometime (about a week), the performance of jobs start degrading. And we found out that the paging start occurring. After that we decided to restart all 3 servers after the whole day batch job finished. After restart, for the next 5-7 days the performance is within our expectation, but after that the paging start happen again. 
Anyone has shine me bright idea how to resolve this or anyone encounter this before ? your input is very much appreciated.

Following is my current AIX Server version

You have to check the memory use for each of your products and check with the editors if they are aware of such things.

Run a perfpmr for details (or just the memdetails.sh script)

Could also be a system bug, and yours is a little old.

Could be a good idea to upgrade the system.
