Clone Oracle Database Homes to the Replacement Compute Server

To clone the Oracle Database homes to the replacement server:

Add Oracle Database ORACLE_HOME to the replacement compute server:

$ cd /u01/app/oracle/product/12.1.0/db_home/addnode/
$ ./addnode.sh -silent "CLUSTER_NEW_NODES={replacement_server}" -ignorePrereq

The addnode script causes Oracle Universal Installer to copy the Oracle Database software to the replacement compute server.

WARNING: The following configuration scripts need to be executed as the "root"
user in each cluster node.
/u01/app/oracle/product/12.1.0/dbhome_1/root.sh #On nodes ra01db01
To execute the configuration scripts:
Open a terminal window.
Log in as root.
Run the scripts on each cluster node.

After the scripts are finished, the following messages appear:

The Cluster Node Addition of /u01/app/oracle/product/12.1.0/dbhome_1 was
successful.
Please check '/tmp/silentInstall.log' for more details.

Run the root.sh script on the replacement compute server:
```
# /u01/app/oracle/product/12.1.0/dbhome_1/root.sh
 
```
Check the /u01/app/oracle/product/12.1.0/dbhome_1/install/root_replacement_server.company.com_date.log file for the output of the script.

Ensure that the instance parameters are set for the replaced database instance. The following is an example for the CLUSTER_INTERCONNECTS parameter.

SQL> SHOW PARAMETER cluster_interconnects

NAME                                 TYPE        VALUE
------------------------------       --------    -------------------------
cluster_interconnects                string
 
SQL> ALTER SYSTEM SET cluster_interconnects='192.168.73.90' SCOPE=spfile SID='dbm1';

Validate the configuration files and correct them as necessary:
- The ORACLE_HOME/dbs/initSID.ora file points to server parameter file (SPFILE) in the Oracle ASM shared storage.
- The password file that is copied in the ORACLE_HOME/dbs directory has been changed to orapwSID.
Restart the database instance.
