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. -- //www.freelists.org/webpage/oracle-l
