Hi,
I am trying to validate the following statement for red hat linux 64bit 5.4, 
11.2.0.2:

It is a best practice to limit the number of operating system processes to no 
more than 8 times the number of CPU cores


Does this sound reasonable? This would mean on a 32 core system I would be 
limited to no more 256 processes to serve my queries. In a partitioned data 
warehouse.

Thanks for your time,

JoshC.
