These two methods should be implemented in src/aix/native/sun/management/AixOperatingSystem.c (which has to be created).

getProcessCpuLoad() can be probably implemented in the same way like on Solaris be reading /proc/self/psinfo

For getSystemCpuLoad() we'll probalby have to use 'perfstat_cpu_total()' from libperf (see http://publib.boulder.ibm.com/infocenter/pseries/v5r3/topic/com.ibm.aix.prftools/doc/prftools/prftools07.htm#wq407)

Once this issue has been resolved you should not forget to remove the two excludes from jdk/test/ProblemList.txt:

com/sun/management/OperatingSystemMXBean/GetProcessCpuLoad.java aix-all
com/sun/management/OperatingSystemMXBean/GetSystemCpuLoad.java aix-all
