SUT Notes
APAR IY09807: New hardware support for May-2000
no(network option) tuning:
no -o send_file duration=180000(cached send_file expiration time, default=300)
nbc_max_cache=131072(max file size for network buffer cache,default=1048576)
somaxconn=8192(max listen backlog, default=1024)
nbc_pseg=20000(max file entries in private segment,default=0)
tcp_timewait=5(ensure that TIME_WAIT is at least 60 seconds, default=1)
Processor affinity - bind 6 Ethernet interrupts to 6 cpu's(1 interrupt to 1 cpu)
maxpgahead=32(the maximum number of pages to be read ahead,default=8)
maxfree=152(the number of frames on the free list at which page stealing is to stop,default=128)
minperm=5%(the point below which the page-stealer will steal file of computational pages,default=20%)
maxperm=95%(the point above which the page stealing algorithm steals only file page,default=80%)
Client Notes
