本文介绍了Oracle11gR2 Grid Infrastructure的rootcrs.pl命令使用方法，包括如何重新配置Grid Infrastructure及ASM，以及如何彻底卸载Grid Infrastructure。还详细展示了deinstall命令的具体操作流程。

Oracle 11g R2 Grid Infrastructure 的安装与配置较之前的版本提供了更多的灵活性。在Grid Infrastructure安装完毕前执行root.sh经常容易出现错误，并且需要修复该错误才能得以继续。

在这个版本中我们可以直接通过执行脚本rootcrs.pl来重新配置Grid Infrastructure而无需先卸载Grid Infrastructure，然后修复故障后进行再次安装。下面描述了rootcrs.pl的用法以及使用deinstall彻底卸载Grid Infrastructure。

1、rootcrs.pl命令介绍

#命令位置:$GRID_HOME/crs/install

#命令说明:

# 该命令主要是用于对crs进行维护与管理，包括patch,upgrade,downgrade,deconfig等等

# perldoc rootcrs.pl执行这个命令获得完整的介绍

[root@linux1 install]# ./rootcrs.pl -h

Unknown option: h

Usage:

rootcrs.pl [-verbose] [-upgrade | -patch] [-hahome ]

[-paramfile ]

[-deconfig | -downgrade] [-force] [-lastnode]

[-downgrade] [-oldcrshome ] [-version ]

[-unlock [-crshome ]]

Options:

-verbose Run this script in verbose mode

-upgrade Oracle HA is being upgraded from previous version

-patch Oracle HA is being upgraded to a patch version

-hahome Complete path of Oracle Clusterware home

-paramfile Complete path of file specifying HA parameter values

-lastnode Force the node this is executing on to be considered the

last node of the install and perform actions associated

with configurig the last node

-downgrade Downgrade the clusterware

-version For use with downgrade; special handling is required if

downgrading to 9i. This is the old crs version in the format

A.B.C.D.E (e.g 11.1.0.6.0).

-deconfig Remove Oracle Clusterware to allow it to be uninstalled or reinstalled.

-force Force the executon of steps in delete that cannot be verified

to be safe

-unlock Unlock CRS home

-crshome Complete path of crs home. Use with unlock option.

-oldcrshome For use with downgrade. Complete path of the old crs home.

If neither -upgrade nor -patch is supplied, a new install is performed

To see the full manpage for this program, execute:

perldoc rootcrs.pl

#对于执行root.sh失败时，我们可以通过该命令以-deconfig 参数来清除crs的配置信息，然后根据log修复故障或使用patch之后再重新执行root.sh

#对于该命令的patch,upgrade,downgrade用法再此不作详细介绍

2、重新配置Grid Infrastructure及ASM

[python]

#重新配置Grid Infrastructure并不会移除已经复制的二进制文件，仅仅是回复到配置crs之前的状态，下面是其步骤

a、使用root用户登录，并执行下面的命令(所有节点，但最后一个节点除外)

# perl $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force

b、同样使用root用户在最后一个节点执行下面的命令。该命令将清空ocr 配置和voting disk

# perl $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode

c、如果使用了ASM磁盘，继续下面的操作以使得ASM重新作为候选磁盘(清空所有的ASM磁盘组)

# dd if=/dev/zero of=/dev/sdb1 bs=1024 count=100

# /etc/init.d/oracleasm deletedisk DATA /dev/sdb1

# /etc/init.d/oracleasm createdisk DATA /dev/sdb1

3、彻底删除Grid Infrastructure

[python]

#11g R2 Grid Infrastructure也提供了彻底卸载的功能，deinstall该命令取代了使用OUI方式来清除clusterware以及ASM，回复到安装grid之前的环境。

#该命令将停止集群，移除二进制文件及其相关的所有配置信息。

#命令位置:$GRID_HOME/deinstall

#下面是该命令操作的具体事例，操作期间，需要提供一些交互信息，以及在新的session以root身份清除一些/tmp下的文件

[root@linux1 bin]# ./crsctl check crs
