ORACLE 11g RAC 集群的管理与维护（3） —— crsctl 命令之（三）：管理 crs

CRS（Cluster Ready Service，集群就绪服务）。CRS 主要完成集群成员管理、心跳监控、故障切换等功能。通过 CRS 将多个节点的操作系统绑定到一起，客户端对集群的访问就像访问一台服务器一样。CRS 包括 voting disk（表决磁盘）和 Oracle Cluster Registry（OCR，Oracle 集群注册服务）。

（1）voting disk（表决磁盘）：表决磁盘放在共享存储，以保证每个节点都能访问。当集群节点发生故障时，通过表决磁盘进行投票仲裁。
（2）Oracle Cluster Registry（OCR，集群注册服务）：用于记录 RAC 集群和数据库的配置信息。包括集群节点的列表、集群数据库实例到节点的映射以及 CRS 应用程序资源信息。

一、查询 CRS 的相关信息

1、crsctl query crs administrator

查询具有 Oracle Clusterware 管理权限的用户列表：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl query crs administrator
CRS Administrator List: *

2、crsctl query crs activeversion

查询集群中运行的 Oracle Clusterware 软件的 activex 版本：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.4.0]

3、crsctl query crs releaseversion

查询本地节点上二进制文件中存储的 Oracle Clusterware 软件的版本：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl query crs releaseversion
Oracle High Availability Services release version on the local node is [11.2.0.4.0]

4、crsctl query crs softwareversion

查询在当前节点或指定节点上成功启动的软件的最新版本：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl query crs softwareversion
Oracle Clusterware version on node [rac1] is [11.2.0.4.0][root@rac1 bin]# ./crsctl query crs softwareversion rac1
Oracle Clusterware version on node [rac1] is [11.2.0.4.0][root@rac1 bin]# ./crsctl query crs softwareversion rac2
Oracle Clusterware version on node [rac2] is [11.2.0.4.0]

5、crsctl check crs

查询本地服务器上 OHAS 和 Oracle Clusterware 的状态：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./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

6、crsctl config crs

查询 HAS 自动启动配置：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl config crs
CRS-4622: Oracle High Availability Services autostart is enabled.

二、禁用和启用 CRS 的自动启动配置

1、rsctl disable crs

禁用 CRS 的自动启动配置：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.[root@rac1 bin]# ./crsctl config crs
CRS-4621: Oracle High Availability Services autostart is disabled.

2、crsctl enable crs

启用 CRS 的自动启动配置：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl enable crs
CRS-4622: Oracle High Availability Services autostart is enabled.[root@rac1 bin]# ./crsctl config crs
CRS-4622: Oracle High Availability Services autostart is enabled.

三、启动和停止本地服务器上的 CRS

1、crsctl stop crs [-f]

停止本地服务器上的 CRS：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl stop crs -f

说明：
（1）该命令试图停止 Oracle Clusterware 管理的资源，同时试图停止本地服务器上的 OHAS。
（2）如果在运行 crsctl stop crs 命令之后，Oracle Clusterware 管理的任何资源仍在运行，那么该命令将失败。
（3）使用 -f 选项暂停所有资源并停止本地服务器上的 OHAS。
（4）如果打算在所有节点或节点列表上停止 Oracle Clusterware，需要使用 crsctl stop cluster 命令。

2、crsctl start crs

启动本地服务器上的 CRS：

[root@rac1 bin]# pwd
/u01/app/11.2.0/grid/bin[root@rac1 bin]# ./crsctl start crs
CRS-4123: Oracle High Availability Services has been started.[root@rac1 bin]# ./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
