Srvctl命令式RAC维护中最常用的命令也是最复杂的命令。这个工具用来维护一下几种资源：Database,Instance,ASM,Service,Listener和Node Application，node Application又包括GSD,ONS,VIP。
Srvctl命令的用法：
[root@felix2 bin]# ./srvctl -help
Usage: srvctl
command:enable|disable|start|stop|relocate|status|add|remove|modify|getenv|setenv|unsetenv|config
objects:database|instance|service|nodeapps|asm|listener
For detailed help on each command and object andits options use:
