Processes and CPU/memory

Below is the output from a "ps -ef |grep PST" command on our 5.2 server. You can see that there are 9 of these XactPST.p processes running. There are hundreds of other types of processes running on this p670. Every morning when our system comes up there is a script that starts these 9 processes. As loan applications come into our system they use these 9 processes to contact our credit bureaus (TRW etc).

As the number of loan applications is growing we need to double or tripple the number of these processes. Is there a good way to know how these additional process will impact our system? For example will we need to purchase more memory/RAM if we go from 9 processes to 27? I guess I need a simple way to see how much memory and cpu each of these processes use.

My recommendations would be:

1. use nmon to look at top processes by memory usage
2. use "svmon -Put 5" to view the top memory users
3. use "ps vg | grep PST | sort -rn +6 " this should sort all the PST processors by usage (top to bottom). You'll need to look at the 6th column - (I think...and I believe the header is RSS).

I did this from memory, so if one of these doesn't work, let me know.
