"cpu usage" given by process caiuxsa2 is different than the value given by the AIX 'topas' command


Process caixusa2, on AIX, collects the CPU metrics from the kernel PPDA structure while 'topas' is using the perfstat API in AIX to collect these data.

Patch T5HI110 provides a new caiuxsa2 file which uses the same API as the 'topas' command.

(This patch has been designed for AIX 5.3 till update 5300-06-01-0000)
