We are using AIX 5L Server (64 Bit) version 5300-05 series. And we have a setup of Oracle Applications on this server. As this is our reports server, Oracle writes many temporary files to this /tmp folder on hdisk0.
When i do topas, i could see that the disk utilization is 100% for most of the times. and this folder is filled and emptied continuously by Oracle. We have also encountered Page outs.
Memory utilization is always less than or equal to 80% and paging utilization is 19%, but during peak time the memory is never utilized fully but paging swap file is utilized fully.
We have 19 GB ram and 8 Processors on dual core and daily we have over 500 users logging concurrently and firing all heavy reports.
Please help me on configuring my server optimally so that i can run my application server peacefully.
