这个命令opcagt 用来管理OMU管理node 的agent进程。这个命令需要sudo/admin权限来执行。在server端有相似的命令opcragt，该命令是server用来管理remote nodes的。

如果在执行opcagt的时候，不接任何option， opcagt会返回本机当前agent的状态。(相当于opcagt  -status)

普 通 用 户 $opcagt                                                                                                                                                      
Only 'root' users and members of group 'bin' can control OV processes

root用户# opcagt

NOTE: 用命令opcragt来管理remote node 的 agent，OMU的agent一定要运行在node上，否则agent不能从OMU管理服务器started / stopped。
