Question How to Setup IDS on Solaris(spark server) for Multiprocessors

Hello All,

I want to set up IDS 10.0(FC4)instance on Sun Spark server, which has one 24 core processor. So i am not sure how should i give the multiprocessor settings in the onconfig files parameters related to that instance. Please find below the parameters about which i need to know the best settings:

NETTYPE ipcshm,?,?,CPU # Configure poll thread(s) for nettype
NETTYPE tlitcp,?,?,NET # Configure poll thread(s) for nettype
RESIDENT 0 # Forced residency flag (Yes = 1, No = 0)

MULTIPROCESSOR 1 # 0 for single-processor, 1 for multi-processor
NUMCPUVPS ? # Number of user (cpu) vps
SINGLE_CPU_VP 0 # If non-zero, limit number of cpu vps to one

NOAGE 1 # Process aging
AFF_SPROC 0 # Affinity start processor
AFF_NPROCS ? # Affinity number of processors

Please guide me with the best setting to have the optimal performance.

Thanks in advance.

Regards,
Omer Saeed Khan
