Finding Cluster node details from RDBMS binary

I am trying to upgrade a Cluster database with  3 nodes from 10.2.0.4.0 to 10.2.05.0. i have a 10205 Cluster & ASM running on it. This is on the test server. i have taken the live copy of binary & oracle inventory to  simulate the live envionment. when i try to upgrade the oracle binary after relink. i got the cluster node entries when i try to upgrade the oracle RDBMS binary.

After a long search, i have found that Oracle RDBMS installer takes the server node details from the below file.


$ /opt/oracle/product/DB10gR2/inventory/ContentsXML> more oraclehomeproperties.xml
<?xml version="1.0" standalone="yes" ?>
