在Oracle 10g中CRS Resource 包括GSD(Global Serveice Daemon),ONS(Oracle Notification Service),VIP, Database, Instance 和 Service
在11gR2里面啟動CRS的時候，會提示ohasd已經啟動。 那么這個OHASD到底包含哪些資源。
[root@racnode1 ~]# crsctl status resource -t

如果要關閉RAC 不能再通過crs_stop -all，這個命令是10g所使用的，在11g由於CRS的信息也是放在ASM 實例里的，所以要關asm,必須關閉crs,在Oracle11g RAC的架構如下
關閉數據庫前建議關閉監聽和kill會話
srvctl stop listener
ps -ef|grep LOCAL=NO|awk -F' ' '{print $2}'|xargs kill -9
要關閉RAC，需在2個節點都配置好root的.bash_profile
export ORACLE_HOME=/u01/grid/product/11gr2 export PATH=$ORACLE_HOME/bin:$PATH
關閉RAC
[root@racnode1 ~]# crsctl stop has [root@racnode2 ~]# crsctl stop has
啟動RAC
[root@racnode1 ~]# crsctl start has [root@racnode2 ~]# crsctl start has
crsctl的其他選項，通過以下命令只需要在一個節點上啟動關閉RAC racnode1是節點的主機名
[root@racnode1 ~]# crsctl stop cluster -n racnode1 racnode2
啟動RAC
[root@racnode1 ~]# crsctl start cluster -n racnode1 racnode2
當直接停止集群時，相關的Resource 也會被停止。 但實際情況下，我們操作更多的是對某些資源的啟動或關閉等操作。具體就是使用SRVCTL 命令。該命令不常用總被忘記，因此可以用幫助選項 –h 來查看命令幫助：
[grid@racnode1 ~]$ srvclt –h
這個命令顯示的結果太長，不好查看，可以進一步的查看幫助：
[grid@racnode1 ~]$ srvctl start -h
通過下列命令直接關閉數據庫，通過上述幫助命令可以查看其他相關操作
[root@racnode1 ~]# srvctl stop database -d prod
crs_ctl -t命令仍然可用，11g rac有個BUG 實例正常啟動，但是狀態是offline
[root@racnode2 ~]# crs_stat -t
