Oracle11g RAC卸载grid报错:

[root@racnode01 ~]# /opt/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force
Can't locate Env.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 . /opt/app/11.2.0/grid/crs/install) at /opt/app/11.2.0/grid/crs/install/crsconfig_lib.pm line 703.

解决方法:
/opt/app/11.2.0/grid/perl/bin/perl /opt/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force
/opt/app/11.2.0/grid/perl/bin/perl  /opt/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force
或者
[root@racnode03 ~]# yum install perl-Env
