Unfortunately true. His Sun Blade should be running Solaris (if memory
serves), so he should be OK with it. Also, he said it was a two way
system (2 x 750Mhz), so should he do something like this:
MULTIPROCESSOR 1 # 0 for single-processor, 1 formulti-processor
NUMCPUVPS 2 # Number of user (cpu) vps
SINGLE_CPU_VP 0 # If non-zero, limit number of cpu vpsto one
Instead of:
MULTIPROCESSOR 0 # 0 for single-processor, 1 formulti-processor
NUMCPUVPS 1 # Number of user (cpu) vps
SINGLE_CPU_VP 0 # If non-zero, limit number of cpu vpsto one
Or if he's got a one processor license:
MULTIPROCESSOR 1 # 0 for single-processor, 1 formulti-processor
NUMCPUVPS 1 # Number of user (cpu) vps
SINGLE_CPU_VP 1 # If non-zero, limit number of cpu vpsto one
Just a thought
