CRS常用维护命令

CRS常用命令

常用的crs命令如下：

$ORA_CRS_HOME/bin/crs_stat–t

此命令主要用来检查crs资源状态

例如

[oracle@postdb2/]$$ORA_CRS_HOME/bin/crs_stat–t

[oracle@postdb2/]$

$ORA_CRS_HOME/bin/crs_start–all

此命令用来启动所有的集群服务，但是启动的前提是资源状态State不能是UNKNOWN。

$ORA_CRS_HOME/bin/crs_start集群服务名（集群服务名可以通过$ORA_CRS_HOME/bin/crs_stat得到）

$ORA_CRS_HOME/bin/crs_stop–all

$ORA_CRS_HOME/bin/crs_stop集群服务名（集群服务名可以通过$ORA_CRS_HOME/bin/crs_stat得到）

上面的一组crs命令是用来启动关闭crs服务的，下面通过一个真实的环境，具体讲解这些命令的使用。

举例如下：

OracleRAC在安装完毕后，重启RAC，一些服务不能启动，手动启动也没用。

下面是系统自动启动以后的情况；

[oracle@postdb1~]$crs_stat–t

[oracle@postdb1~]$

可以看到，只有vip是能自动启动的！

其它资源都处于UNKNOWN状态下。

手工用srvctl启动试试！

$srvctlstartnodeapps-nrac1

可以看到，仍然是启动后的原始状态。

从上面的显示可以知道，每个资源的State显示为UNKNOWN，应该是由于两个节点时间不同步，进而造成crs在启动的时候无法认到系统已经注册的资源造成的。

解决方法：

首先，保证两个节点时间保持同步，ORACLE10gRAC两个节点之间有10几秒的时间误差，不会对应用造成影响。

但是过分大的时间误差可能导致某个节点down机，或者节点不断重启。

然后执行如下操作：

[oracle@rac1~]$$ORA_CRS_HOME/bin/crs_stop–all

Attemptingtostop`ora.rac1.vip`onmember`rac1`

Attemptingtostop`ora.rac2.vip`onmember`rac2`

$ORA_CRS_HOME/bin/crs_stop–all只能停掉State为ONLINE的服务，状态为UNKNOWN的资源不能通过这个命令关闭，因此可以通过$ORA_CRS_HOME/bin/crs_stop服务名的方式单独停止那些状态为UNKNOWN的资源。

下面是通过$ORA_CRS_HOME/bin/crs_stop命令依次停止资源状态State为UNKNOWN的服务。

………….

把所有状态为UNKNOWN的资源全部停止以后，再次查看资源状态：

[oracle@rac1~]$$ORA_CRS_HOME/bin/crs_stat-t
