How to perform ORACLE_HOME/binaries backup

Oracle binaries backup is needed when we are doing any OS  label upgrade like
OEL upgrade .

1. (Suggested but not mandatory) Shutdown databases, listeners, or any other processes related to the ORACLE_HOME which you are taking backup.

2. cd to the directory where ORACLE_HOME is located for example:

cd /u01/app/oracle/product/11.2

3. backup the ORACLE_HOME for example:

tar -pcvf /u01/app/oracle/backup/oracle_home_bkup.tar db1

In the above example, ORACLE_HOME is /u01/app/oracle/product/11.2/db1 and backup the directory is /u01/app/oracle/backup/

Below is an example of restoring the ORACLE_HOME:

1. (This step would be mandatory in the case of restore) Shutdown databases, listeners, or any other processes related to the ORACLE_HOME which you are restoring.

2. Go to the directory where ORACLE_HOME is located for example:

cd /u01/app/oracle/product/11.2

3. Rename or move the current ORACLE_HOME for example:

mv db1 db1_bkup

3. Restore the ORACLE_HOME for example:

tar -pxvf /u01/app/oracle/backup/oracle_home_bkup.tar

Make sure that is enough enough free disk space before doing the backup.
