Re: Unix- HELP! Are we being bluffed?

Hi Greg - Regarding your performance problems mentioned below, please run a UNIX "sar" command during the interval when you have the 4 users doing POs (pardon the pun). The sar report from UNIX will help point to the bottleneck (could be CPU, memory, disk, UNIX tunable, Informix tunable, or something in the application). I've seen many people start at too high a level when looking at performance problems; start with sar and work your way up. If your not familiar with sar, have a UNIX guru down your way help you interpret the output. Make sure that person is familiar with your particular flavor of UNIX.
