In this blog we will show you how to clone an Oracle home to another node using tar. The Oracle home binaries are 11.2.0.3.5 on Linux 6.3. See Also: Database Installation Guide 11g Release 2 (11.2) for Linux: B Cloning an Oracle Home
On source server as user oracle: Stop everything running in the Oracle home. Sample:
$ dbshut
$ lsnrctl stop listener
$ ps -ef|grep oracle
On source server as user root: tar the Oracle home to a location with sufficient space
Note: We also tried this using zip, but with unzip -d all files will be wrongly owned by root
# cd /tmp
# tar -zcvf ohome_112.tar.gz /u01/app/oracle/11.2.0/db_3
On source server as user root: copy tarfile to target
Now copy the tarfile to the target server. Make sure there is enough space on the target location.
# scp ohome_112.tar.gz oracle@target.dom.org:/tmp
On target server as user root: untar, ownerships are preserved
# cd /
# tar -zxvf /ohome_112.tar.gz
On target server as user oracle: run clone.pl.
