Cloning oracle home to new home.

Cloning oracle home to new home.

In this example we have taken already installed oracle home db_1 to create another home in the same server db_2.

Source home: /u01/app/oracle/product/12.1.0/db_1
Clone home: /u01/app/oracle/product/12.1.0/db_2

Use cp command to copy source home to new clone home as below.

[oracle@oratest ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/12.1.0/db_1

[oracle@oratest ~]$ cd /u01/app/oracle/product/12.1.0
[oracle@orahost 11.2.0]$ cp -rp db_1 db_2
cp: cannot open `db_1/bin/nmhs' for reading: Permission denied
cp: cannot open `db_1/bin/nmb' for reading: Permission denied
cp: cannot open `db_1/bin/nmo' for reading: Permission denied


use the runInstaller command in the new Oracle Home as below:

[oracle@oratest 12.1.0]$ cd db_2/oui/bin
[oracle@oratest bin]$ ./runInstaller -silent -clone ORACLE_BASE="/u01/app/oracle" ORACLE_HOME="/u01/app/oracle/product/12.1.0/db_2" ORACLE_HOME_NAME="OraHome2"
