centsos 6上启动和关闭oracle 11gR2 rac

本文链接：https://blog.youkuaiyun.com/weeknd/article/details/72461340

本文档详细介绍了如何在CentOS 6上通过srvctl命令启动和关闭Oracle 11gR2 Real Application Clusters (RAC)。内容包括检查集群资源状态、关闭数据库、停止ASM实例、关闭CRS以及重新启动整个集群的步骤。关闭RAC时，由于OCR盘存储在ASM上，故不能直接关闭ASM，需要先停止CRS。

使用srvctl 启动和关闭rac

在centos 6中启动CRS，CSSD等服务的文件，在/etc/init.d目录下

[root@csicn20db01 init.d]# ls -l init.ohasd

-rwxr-xr-x 1 root root 8782 May 10 13:30 init.ohasd

查看集群的状态

[grid@csicn20db01 ~]$ crsctl status res -t

Note:正确关闭rac有助于理解rac各个资源的依赖关系

关闭rac

1：关闭数据库

[grid@csicn20db01 ~]$ srvctl stop database -d mycim

Note：mycim为数据库

[grid@csicn20db01 ~]$ crsctl status res -t

可以看到数据库offline

2：关闭节点的的asm实例

[grid@csicn20db01 ~]$ srvctl stop asm -n csicn20db01

[grid@csicn20db01 ~]$ srvctl stop asm -n csicn20db02

PRCR-1014 : Failed to stop resource ora.asm

PRCR-1065 : Failed to stop resource ora.asm

CRS-2529: Unable to act on 'ora.asm' because that would require stopping or relocating 'ora.CRS.dg', but the force option was not specified

Note：无法关闭asm，这是因为ocr盘存放在asm盘上，而crsd又是asm的client客户端，所以无法关闭asm，但是后面的提示说强制关闭的方式不受限制

解决方式：

关闭CRS(两个节点都需要执行)

节点二也执行

[root@csicn20db02 bin]# ./crsctl stop crs

Note：可以看到关闭了所有的集群资源和asm实例

启动rac

启动CRS（两个节点都执行）

[root@csicn20db02 bin]# ./crsctl start crs

CRS-4123: Oracle High Availability Services has been started.
