How to activate a hyperthreading processor

Hello,



Is the number of CPUs determined and configured at boot time or at 
installation time?



I installed 10g EE on a Debian Linux system. During installation the 
distro kernel was not capable of hyperthreading but worked.



Now I changed the kernel to a custom built one which uses HT. My scripts 
do use both CPUS, the DBMS doesn't. The DMBS just switches from one to 
the second virtual CPU.



TIA


Marc
