Oracle Database - 18c - RAC Node Addition (RAC DB Home Clone)

This Blog is in continuation with my last blog on GI Clone / Node Addition

In this blog I am going to clone the Oracle Database Home to the newly added Node to the cluster. 


Step 1 - Precheck on the new node
[grid@rac18c03 bin]$ cd /u01/app/180/grid/bin
[grid@rac18c03 bin]$ ./cluvfy stage -pre dbinst -n rac18c03

Pre-check for database installation was successful.

CVU operation performed:      stage -pre dbinst

Date:                         Aug 17, 2018 6:02:55 AM

CVU home:                     /u01/app/180/grid/

User:                         grid

Step 2 - Create required Directories (on New Node)

mkdir -p /u01/app/oracle/product/180/db

chown -R oracle:oinstall  /u01/app/oracle
