Oracle 11g RAC的常用管理

在Oracle 11g RAC中，主要管理工具是srvctl和crsctl。

srvctl(Server Control)是一个命令行工具，可用于管理定义在Oracle Cluster Registry (OCR)上的资源。

这些资源包括节点应用(nodeapps),它构成Oracle Cluterware，而其包括the Oracle Notification Service (ONS), the Global Services Daemon (GSD), and the Virtual IP (VIP)。

其他的资源也可以被SRVCTL管理，如databases, instances, listeners, services, and applications。

通过SRVCTL，可以启动或停止nodeapps、databases、instances、listeners和services，删除或移去instances和services，增加services，管理配置信息。

crsctl(Cluster Ready Services Control )是一个命令行工具，可以用于管理Oracle Clusterware daemons（何谓daemon，又名守护进程、后台进程，名称以字母d结尾）。这些daemon包括Cluster Synchronization Services (CSS), Cluster-Ready Services (CRS), and Event Manager (EVM)。

通过CRSCTL，可以启动或停止Oracle Cluster，确定Oracle Clusterware的当前状态。

通过这两个工具，我们可以管理Oracle 11g RAC。

1、查看各资源状态(nodeapps节点应用程序，ASM实例，数据库实例等)

需要在grid 用户下执行这些命令。

crs_stat -t
这是兼容10g的一个工具。

/home/grid@serv1=>+ASM1$crs_stat -t

crsctl stat  resource -t
这是取代10g的crs_stat的工具。

/home/grid@serv1=>+ASM1$crsctl status resource -t

在11g R2中，默认 oc4j和gsd资源是 disable 的；oc4j  是用于WLM 的一个
资源, WLM在 11.2.0.2 才可用；gsd 是 CRS 用于跟 9i RAC 进行通信的一
个模块,是为了向后兼容才保留的，不影响性能；建议不要刪除, 也不要尝试开
启他们,  忽略即可。 



2、检查cluster运行状态

需要在grid 用户下执行这些命令。

/home/grid@serv1=>+ASM1$crsctl check -h

crsctl check resource {<resName> [...]|-w <filter>} [-n <server>] [-k <cid>] [-d <did>]
Check status of resource(s)

crsctl check css
Check status of Cluster Synchronization Services

 



3、检查nodeapps状态

6、启动和关闭cluster

需要在root用户下执行这些命令。

[root@serv1 bin]# ./crsctl stop cluster -n serv1

[root@serv1 bin]# ./crsctl stop cluster -all

[root@serv1 bin]# ./crsctl stop cluster -n serv1 -f 强制关闭

[root@serv1 bin]# ./crsctl start cluster -n serv1


禁止CRS系统重启而自动启动

[root@serv1 bin]# ./crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.

检查crs配置为是否自动启动

[root@serv1 bin]# ./crsctl  config crs
