1.启动CRS
如果CRS没有启动在使用crs_stat命令查看集群状态的时候将会收到如下的报错信息。
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
在RAC环境下启动所有节点上的CRS。
[root@rac1 ~]# /oracle/app/crs/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
[root@rac2 ~]# /oracle/app/crs/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
集群从启动到全部启动完毕的总时间与系统想能和配置有关，一般需要3~10分钟的时间，请耐心等待。
注意：为保证集群环境可以正常无误的启动，一定要确保集群环境中各个节点的时钟保持一致。
与之对应的停止CRS命令为：“crsctl stop crs”。
2.查看CRS资源状态
集群资源启动完毕后，以在第一节点查看集群状态为例。
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
Name Type Target State Host

3.关闭特定集群资源
1）获取集群资源名的方法
crs_stat命令会给出集群资源名的基本信息，结合适当的Shell技巧便可以得到当前环境下集群资源名信息。
RACDB1@rac1 /home/oracle$ crs_stat | grep -i name= | cut -d '=' -f2
ora.RACDB.RACDB1.inst
ora.RACDB.RACDB2.inst
ora.RACDB.db
ora.RACDB.taf.RACDB1.srv
ora.RACDB.taf.RACDB2.srv
ora.RACDB.taf.cs
ora.rac1.ASM1.asm
ora.rac1.LISTENER_RAC1.lsnr
ora.rac1.gsd
ora.rac1.ons
ora.rac1.vip
ora.rac2.ASM2.asm
ora.rac2.LISTENER_RAC2.lsnr
ora.rac2.gsd
ora.rac2.ons
ora.rac2.vip
2）以关闭ora.RACDB.RACDB1.inst资源为例
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stop ora.RACDB.RACDB1.inst
Attempting to stop `ora.RACDB.RACDB1.inst` on member `rac1`
Stop of `ora.RACDB.RACDB1.inst` on member `rac1` succeeded.
提示已成功关闭RACDB1数据库实例。
确认关闭后集群资源状态：
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t

有关更多的srvctl命令的参考可以通过下面的方法获得：
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/srvctl
Usage: srvctl <command> <object> [<options>]
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 <command> <object> -h
使用“-h”选项可以获得更加详细的用法。
8.停止当前节点所有CRS资源

10.对CRS后台进程做健康检查
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
11.检查OCR
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 104216
Used space (kbytes) : 4604

12.检查表决磁盘
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl query css votedisk

located 1 votedisk(s).
13.小结
以上演示了在RAC环境与CRS有关的维护命令，这些命令的使用频率较高，需要熟练掌握。管理CRS的命令较多，建议对每一个命令的具体选项做实际的测试，以便降低误操作的风险。
