In this blog, we will add new node node3 to the existing cluster. ( where grid is already running)

Grid_Home :/u01/app/19c/grid
Oracle_home : /u01/app/oracle/product/19C/db_home.
Steps to Add a node to Cluster :
1. 1. Run script from existing node.
db_home$ export GRID_HOME=/u01/app/19c/grid
db_home$ cd $GRID_HOME


Run script from the new node node2.


Check the cluster resources: crsctl stat res -t

Extend Oracle Database home to new node using

If oracle database home is installed on existing node, then we need to extend the same oracle_home to new node. script need to be run from the existing node.

cd $ORACLE_HOME/addnode


Run on new node node3

2. Add the instance on node using dbca utility( run on node2(existing node))

 cd $ORACLE_HOME/bin

[second node]$ crsctl status resource -w “TYPE = ora.database.type” -t
