Oracle 11g RAC 的启动与关闭

时间:2021-08-19 23:29:30


在Oracle 10g中CRS Resource 包括GSD(Global Serveice Daemon),ONS(Oracle Notification Service),VIP, Database, Instance 和 Service 

在11gR2里面启动CRS的时候,会提示ohasd已经启动。 那么这个OHASD到底包含哪些资源。
[root@racnode1 ~]# crsctl status resource -t

 如果要关闭RAC 不能再通过crs_stop -all,这个命令是10g所使用的,在11g由于CRS的信息也是放在ASM 实例里的,所以要关asm,必须关闭crs,在Oracle11g RAC的架构如下 

Oracle 11g RAC 的启动与关闭
Oracle 11g RAC 的启动与关闭
要关闭RAC,需在2个节点都配置好root的.bash_profile
export ORACLE_HOME=/u01/grid/product/11gr2
export PATH=$ORACLE_HOME/bin:$PATH
关闭RAC
[root@racnode1 ~]# crsctl stop has
[root@racnode2 ~]# crsctl stop has
启动RAC
[root@racnode1 ~]# crsctl start has
[root@racnode2 ~]# crsctl start has
crsctl的其他选项,通过以下命令只需要在一个节点上启动关闭RAC  racnode1是节点的主机名
[root@racnode1 ~]# crsctl stop cluster -n racnode1 racnode2
启动RAC
[root@racnode1 ~]# crsctl start cluster -n racnode1 racnode2
 
 
当直接停止集群时,相关的Resource 也会被停止。 但实际情况下,我们操作更多的是对某些资源的启动或关闭等操作。具体就是使用SRVCTL 命令。该命令不常用总被忘记,因此可以用帮助选项 –h 来查看命令帮助: 
[grid@racnode1 ~]$  srvclt –h 
这个命令显示的结果太长,不好查看,可以进一步的查看帮助: 
 [grid@racnode1 ~]$ srvctl start -h 
 
 
通过下列命令直接关闭数据库,通过上述帮助命令可以查看其他相关操作
[root@racnode1 ~]# srvctl stop database -d prod
 
crs_ctl -t命令仍然可用,11g rac有个BUG 实例正常启动,但是状态是offline
[root@racnode2 ~]# crs_stat -t
