AIX系统Memory性能评估
2008-05-09 08:16:09 来源:WEB开发网 #vmo -o maxperm%=80 -o minperm%=20
Setting minperm% to 20
Setting maxperm% to 80
在AIX 5.2之前的版本请使用/usr/samples/kernel/vmtune命令。
#/usr/samples/kernel/vmtune -p 20–P 80 将min和max的值分别设置为20%和80%。
查看当前的参数设置方法如下:
1)vmo –a 显示当前所有的参数设置
在AIX 5.2之前的版本请使用 # /usr/samples/kernel/vmtune 显示当前所有的参数设置
#vmo -a
