安装完AIX5.2后,发现root用户执行sar,vmstat等命令的权限是denied:
# sar 2 2
sar: The file access permissions do not allow the specified action.
Versions of sadc and sar are inconsistent.
# vmstat 2 2
ksh: vmstat: 0403-006 Execute permission denied.
# iostat 2 2
ksh: iostat: 0403-006 Execute permission denied.

root 用户不是默认的超级用户吗,它默认是system,adm等组的啊,应该有执行的权限啊!?
为什么出现这种情况呢?

我把/usr/lib/sa/sadc的权限改为可执行后,sar命令能正常执行.
其他命令一个个更改权限倒是可以执行,现在就想不通为什么会这样呢.是否可以通过简便途径更改权限呢?
#ls -l /usr/lib/sa/sadc
---------- 1 root    adm          13556 Aug 20 2003  /usr/lib/sa/sadc
加执行权限后为---------x

root用户的状态:

请各位高手点拨一下!是否可以通过简便途径更改权限呢?
