使用案例

检查crs状态

$ crsctl check crs

CSS appears healthy

CRS appears healthy

EVM appears healthy

检查单个状态 

$ crsctl check css

CSS appears healthy

启动crs栈，必须使用root用户

# ./crsctl start crs

Attempting to start CRS stack 

The CRS stack will be started shortly 

停止crs栈，必须使用root用户

# ./crsctl stop crs 

Stopping resources. 

Successfully stopped CRS resources 

Stopping CSSD. 

Shutting down CSS daemon. 

Shutdown request successfully issued.

配置crs进程栈是否随着操作系统的启动而自启动，有时出于维护目的需要关闭这个特性，可以用root用户执行下面命令。 

# ./crsctl disable crs 

# ./crsctl enable crs 

这个命令实际是修改了/etc/oracle/scls_scr/raw/root/crsstart这个文件里的内容。

查看votedisk磁盘位置

$ crsctl query css votedisk

 0.     0    /dev/raw/raw2

located 1 votedisk(s).

增加votedisk

# ./crsctl add css votedisk /dev/raw/raw3 -force
Now formatting voting disk: /dev/raw/raw3
successful addition of votedisk /dev/raw/raw3. 

删除votedisk

# ./crsctl delete css votedisk /dev/raw/raw4 -force
successful deletion of votedisk /dev/raw/raw4.

关于维护votedisk的相关内容可以查看笔者的如下博客

查看crs参数

$crsctl get css misscount

60

修改crs参数,必须为root用户

# ./crsctl set css miscount 60

跟踪crs模块，提供辅助功能

CRS由CRS，CSS，EVM三个服务组成，每个服务又是由一系列module组成，crsctl允许对每个module进行跟踪，并把跟踪内容记录到日志中。 

$ crsctl lsmodules css

The following are the CSS modules :: 

    CSSD

    COMMCRS

    COMMNS

$ crsctl lsmodules evm

The following are the EVM modules :: 

   EVMD

   EVMDMAIN

   EVMCOMM

   EVMEVT

   EVMAPP

   EVMAGENT

   CRSOCR

   CLUCLS

   CSSCLNT

   COMMCRS

   COMMNS

跟踪CSSD模块，需要root用户执行： 

# ./crsctl debug log css "CSSD:1"

Configuration parameter trace is now set to 1.

Set CRSD Debug Module: CSSD  Level: 1
