ORACLERAC集群的启动和关闭,RAC集群的启动和关闭,貌似非常的简单,敲来敲去也就是那五六个命令。但是深入理解下去,非常有助于我们了解RAC的构架.

 启动和关闭rac一般使用三种方式:sqlplus,srvctl以及dbconsole或者Oracle grid control,本节中简要介绍下使用srvctl启动和关闭rac数据库集群!

使用crs_stat命令可以查询当前rac各节点下的asm实例,监听器,global service daemon,oracle notification server,vip,数据库实例是否正常!

复制代码
[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ crs_stat -t -v

srvctl命令的使用
srvctl是service control的缩写,基本的用法是srvctl


[],使用srvctl命令,可以对rac各个节点的数据库实例,asm实例和监听器等进行管理,挺方便的工具复制代码
oracle@rac2 ~]$ srvctl 
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 and its options use: srvctl
-h 获取更详细的帮助 [oracle@rac2 ~]$ srvctl start asm -h Usage: srvctl start asm -n [-i ] [-o ] [-c | -q] -n Node name -i ASM instance name -o Options to startup command (e.g. open, mount, or nomount) -c Connect string (default: / as sysdba) -q Query connect string from standard input -h Print usage
