This topic describes how to tune the AIX operating system to optimize the performance of your WebSphere Application Server.
Why and when to perform this task
There are a number of configuration changes and variables you can set to tune the performance of Websphere to suit your needs. Because the AIX operating system is not a WebSphere Application Server product, be aware that it can change and results can vary.Step for this task
/usr/sbin/no –o tcp_timewait =1
Soft FILE Size -1 Soft CPU Time -1 Soft STACK Size -1 Soft CORE File Size -1 Hard FILE Size -1 Hard CPU Time -1 Hard STACK Size -1 Hard CORE File Size -1
no -o tcp_keepidle=600
no -o tcp_keepintvl=10
no -o tcp_keepinit=40
vmo -r -o lgpg_regions=256 -o lgpg_size=16777216 bosboot -ad /dev/ipldevice reboot -q
vmo -p -o v_pinshm=1
chuser capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE $USER
vmstat -l 1
