Hi,
Oracle 10.2.0.3
AIX 6.1
I have been asked to do some stress testing and it is causing me stress
;-)
I need to really hammer the CPU's on the box as we want to test
dynamically allocating CPU's from another partition to handle the
increased workload.
I am having difficulty getting the CPU's maxed out or indeed to even use
more than 2.
I have been running cartesian joins with various hints (parellism, using
hashes etc) but just cannot get the relevant amount of work generated.
It tends to spike at about 80% on a couple of CPU's then the result set
comes back after about 30 secs and CPU useage then obviously drops. This
is a T & D server with 16 CPU's on it. Are there any clever tricks out
there I can use to simulate a full on workload??
TIA
Lee
