UBE Kernel and Job Queue

I am running on EnterpriseOne 8.11 SP1, Sun Solaris. Some queries on UBE Kernel and job queue, pls advice. Thanks in advance.

1. Do you know how to adjust the maxNumberOfProcesses in JDENET_KERNET_DEF2? Default value is 4. I read somewhere this value should be calcuated as, Number of CPUs - 1, is this true?

[JDENET_KERNEL_DEF2]
krnlName=UBE KERNEL
dispatchDLLName=libjdeknet.so
dispatchDLLFunction=JDEK_DispatchUBEMessage
maxNumberOfProcesses=4
numberOfAutoStartProcesses=0

2. Is idle job queue in JDE consumes of logic server's memory? How much of memory require by each job queue (at idle state)?

You really shouldn't need no more than to UBE kernels running at one time. The only functions they carry out is to perform the initial submission of a batch job and to retrieve PDF and log files when users want to view them.
