oracle process and LWP on solaris 8 box
Hi all,

Without oracle tunning I understand that oracle processes always run on a single CPU at a time (the prstat output always show 1 CPU number) even on multi-processor hardware.
Is it correct?

I do not see how this could be correct when Oracle provides all kinds of parallel operations, which will take advantage of multiple CPUs when available. It is true that these parallel operation are in actuallity multi-threaded operations but they can scale to a higher number of threads on multiple CPU systems.

Have a read here for Thomas Kyte's explanation of UNIX and Oracle processes.
