Description:

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

Solution:

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)
