11g (single instance) on AIX 6.1 : parallelism

Hi

In 11g (single instance) on AIX 6.1   , in order to implement parallelism how to choose   :

- DOP (Degree Of Parallelism) : AUTO ? PARALLEL_DEGREE_POLICY=AUTO is enough ? recommended ?

According to http://docs.oracle.com/cd/E11882_01/server.112/e25523/parallel002.htm

DOP = PARALLEL_THREADS_PER_CPU x CPU_COUNT (single instance)

but what about cores per CPU ?

How to know PARALLEL_THREADS_PER_CPU ?

How to choose PARALLEL_MAX_SERVERS ?

Other important parameters to implement parallelism ?

Thanks.

GD.

Howdy, Stranger!
