oracle 11g rac-root.sh报错-rac1执行成功之后，rac2再执行

 

当第一次root不成功，第二次执行时会遇到这样的错误：
[root@dbserver1 ~]#/apps/oracle/11.2.0/grid/root.sh
……

Now product-specific root actions will be performed.

CRS is already configured on this node for crshome=0
Cannot configure two CRS instances on the same cluster.
Please deconfigure before proceeding with the configuration of new home.

可以执行下面的命令后再重新做。

[root@dbserver1 ~]# /apps/oracle/11.2.0/grid/crs/install/roothas.pl -delete -force -verbose

然后再做就没问题了：

[root@dbserver1 ~]#/apps/oracle/11.2.0/grid/root.sh
