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
-
-
-
-
-
[root@linux1 install]
-
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

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
-
-
-
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)
-
-
-
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
-
-
-
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)
