1. 关于CRSCTL
crsctl是我们和集群软件之间的一个接口，它调用API来操作集群
11.2开始提供一个集群相关的(cluster-aware)的命令让我们对集群进行开启关闭和检查动作
我们可以使用crsctl进行
开启和期待Oracle集群资源
启用和禁用集群进程
检查集群健康状况
管理第三方应用资源
集成 Intelligent Platform Management Interface (IPMI)用来提供故障隔离支持以及确保集群一致性
调试Oracle集群组件
1.1 Clusterized (Cluster Aware)命令
我们可以在一个节点中使用crsctl远程操作其他节点，这个称为Clusterized (Cluster Aware) Commands
它包括:
crsctl check cluster
crsctl start cluster
crsctl stop cluster
1.2 一些备忘
crsctl位于Grid_home/bin
很多crsctl可以使用-f参数强制执行而不用进行相关检测
不要使用早期版本的crsctl操作11.2版本的集群
1.3 以前版本废弃的命令对比
下表为废弃的命令和替代命令对
2.CRSCTL命令参考
crsctl命令可分为三类:
Dual Environment 既可用于RAC环境也可用于Restart环境
Oracle RAC Environmen 只能用于RAC环境
Oracle Restart Environment 只能用于Restart环境，及OHAS服务
这里列出比较重要的，全部命令请查看
https://docs.oracle.com/cd/E11882_01/rac.112/e41959/crsref.htm#CWADD91147
2.1 Dual Environment
crsctl check css
该命令用来检查Cluster Synchronization Services
crsctl check css
CRS-4529: Cluster Synchronization Services is online
crsctl check evm
该命令用来检查 Event Manager
crsctl check evm
CRS-4533: Event Manager is online
crsctl get hostname
该命令用来获取本地hostname
$ crsctl get hostname
lixora01
crsctl start resource
该命令开启许多空闲的资源,多个资源指定方式有:
多个资源以空格隔开
filter过滤
-all指定全部
crsctl start resource {resource_name [...] | -w filter | -all} [-n server_name]
[-k cid] [-d did] [-env "env1=val1,env2=val2,..."] [-i] [-f]
举例:
# crsctl start resource myResource -n server1
crsctl status resource
该命令用来获取一个或多个resoure的状态
crsctl status resource -t
crsctl stop resource
该命令用来停止运行中的资源
crsctl stop resource {resource_name [...] | -w "filter" | -all} [-n server_name]
[-k cid] [-d did] [-env "env1=val1,env2=val2,..."] [-i] [-f]
$ crsctl stop resource -n node1 -k 2
crsctl status type
该命令用来获取一个或多个type的状态
crsctl status type resource_type_name [...]] [-g] [-p] [-f]
$ crsctl status type ora.network.type
TYPE_NAME=ora.network.type
BASE_TYPE=ora.local_resource.type
2 Oracle RAC Environment
我们可以使用命令对RAC做如下操作
Oracle Clusterware, the member nodes and server pools
Oracle ASM (if installed)
Cluster Synchronization Services
Cluster Time Synchronization Services
crsctl add crs administrator
该命令增加一个用户只crs administrator组
crsctl add crs administrator -u user_name [-f]
# crsctl add crs administrator -u scott
crsctl add css votedisk
该命令用来增加voting disk，必须为设备名不能为ASM磁盘组
$ crsctl add css votedisk stor/grid/ -purge
$ crsctl add css votedisk stor/grid/ -purge
crsctl check cluster
该命令用来检查集群的状态(可以是整个集群的CRS)
crsctl cluster [-all | [-n server_name [...]]
$ crsctl check cluster -all
crsctl check crs
该命令检查当前节点的OHAS和CRS
$ crsctl check crs
CRS-4638: Oracle High Availablity Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
crsctl check resource
该命令用来检查资源状态
语法:
crsctl check resource {resource_name [...] | -w "filter" }
[-n node_name] [-k cardinality_id] [-d degree_id] }
举例:
$ crsctl check resource appsvip
crsctl check ctss
该命令用来检查Cluster Time Synchronization services
crsctl check ctss
CRS-4700: The Cluster Time Synchronization Service is in Observer mode.
crsctl config crs
该命令用来显示OHAS自启动配置，root用户执行
crsctl config crs
CRS-4622: Oracle High Availability Services autostart is enabled.
crsctl delete crs administrator
该命令用来从crs administrator组删除用户
语法:
crsctl delete crs administrator -u user_name [-f]
举例:
# crsctl delete crs administrator -u scott
crsctl delete node
该命令用来删除节点
必须使用root用户执行
crsctl delete node -n node_name
# crsctl delete node -n node06
crsctl disable crs
该命令用来禁用OHAS的开机自启动
crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.
crsctl stop cluster
该命令用来停止指定节点或所有节点的集群服务
crsctl stop cluster [-all | -n server_name [...]] [-f]
# crsctl stop cluster -n node1
crsctl stop crs
该命令用于停止一个节点的集群服务
2.3 Oracle Restart Environment
前面我们说到集群服务启动首先是启动OHAS服务的
所以OHAS服务一旦停止，所有节点都将停止
crsctl check has
该命令用来检查ohasd的状态
crsctl check has
CRS-4638: Oracle High Availability Services is online
crsctl config has
该命令用来显示High Availability Services的自启动配置
crsctl config has
CRS-4622 Oracle High Availability Services autostart is enabled.
crsctl disable has
用来禁用 High Availability Services开机自启动
crsctl disable has
CRS-4621 Oracle High Availability Services autostart is disabled.
crsctl enable has
用来启用High Availability Services开机自启动
crsctl enable has
CRS-4622 Oracle High Availability Services autostart is enabled.
crsctl start has
用来启动Oracle High Availability Service
crsctl start has
crsctl stop has
用来关闭Oracle High Availability Service
crsctl stop has
