oracle 12c 集群安装后的检查

1、检查集群节点及状态：
[root@rac2 ~]# olsnodes -s
rac1 Active
rac2 Active
rac3 Active
rac4 Active
[root@rac2 ~]#
可以看到集群的节点和状态信息。
2、检查crs
[root@rac2 ~]# crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
[root@rac2 ~]#
只会列出当前节点的服务，可以看到四个集群的主要服务都是online的。

3、想看全部集群节点的情况：
[root@rac2 ~]# crsctl check cluster -all
**************************************************************
rac1:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
rac2:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
rac3:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
rac4:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
[root@rac2 ~]#
可以看到四个节点的集群状态，但是只能看到三个服务，其实看到这三个都是online，可以确定集群高可用服务ohasd也是活的。因为这个命令本身需要统计别的节点的集群信息，就是通过集群的高可用服务来进行通信的。

4、查看集群的资源：
[grid@rac2 ~]$ crsctl stat res -t

注意，集群的停止需要使用root用户权限。上面的命令只会停止一个集群节点。停止一个节点后的资源情况：

[root@rac3 ~]#

6、集群的停止，第二种方式：

[root@rac3 ~]# crsctl stop cluster -all
[root@rac3 ~]# crsctl stop crs
第一条命令会停止集群所有节点的csc、crs、evm三个服务。而第二条命令会停止当前执行命令的节点的ohasd高可用服务。
所以 第一条命令只需要一个节点上执行一次，第二条命令需要全部节点都执行一次。

7、集群的启动，3中方式，对应上面的集群停止。
第一种：
[root@rac3 ~]# crsctl start crs
启动当前节点。需要所有节点都执行。
[root@rac2 ~]# crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager
[root@rac2 ~]# crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
[root@rac2 ~]#
第二种：
[root@rac3 ~]# crsctl start has
[root@rac3 ~]# crsctl start cluster
第三种：
直接通过oracle提供的自启动脚本启动：
/etc/init.d/init.ohasd run
[root@rac2 init.d]# pwd
/etc/init.d
[root@rac2 init.d]# ll *ohasd
-rwxr-xr-x. 1 root root 9114 10月 22 14:36 init.ohasd
-rwxr-xr-x. 1 root root 7148 10月 22 14:36 ohasd
[root@rac2 init.d]# nohup ./init.ohasd run &
通过脚本启动，4个节点都需要执行。
