2 On one of the remaining nodes, as user root , type the following command:
<ORACLE_CRS_HOME>install/rootdelete
node.sh <public nodename>, <node-number> , where
<ORACLE_CRS_HOME> is similar to
/u01/app/oracle/product/11.1.0./crs/ .
<public nodename> is the public name and <nodenumber> is the node
number of the node being deleted.
3 To determine the node number of any node, type the following command:
<ORACLE_CRS_HOME>bin/olsnodes –n ,
where <ORACLE_CRS_HOME> is similar to

4 On the node that you are deleting, if you wish to remove the Oracle CRS
software, type the following command:
