核心提示: #vmo -o maxperm%=80 -o minperm%=20Setting minperm% to 20Setting maxperm% to 80在AIX 5.2之前的版本请使用/usr/samples/kernel/vmtune命令,#/usr/samples/kernel/v

  #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
