Before we go further into this section, we need to understand the purpose of
cloning and advantage of cloning the Oracle home binaries.
At what circumstance, cloning oracle home is useful?
1) When you setup the standby database, you don't
want to install the oracle binary from the scratch. You might install some extra component or you
might miss some component which is not in primary database. The best
practice, it is always primary and standby should be Apple to Apple. Binary
cloning will be appropriate for setting up the standby database server.
2) If you are performing multiple oracle database
installations on several server as Production, Pre-production, Development, QA
and Test, then you may want to use binary cloning to make sure you install same
component across the environment. This approach is much faster than
installing from the scratch and then applying PSU/CPU patch on each
The Binary version is 18.104.22.168
Oracle home : /ora/app/oracle/product/11.2.0/db_4
Step 1(Clone the binary in source database)
Login to source database:
tar -cvf oracle_110204_binaries.tar db_4
check tar -tvf
The above command ensure the binaries are zipped.
scp the oracle_11204_binaries.tar file to devdb13 under /ora/app/oracle/product/11.2.0/
On step1, oracle binaries are cloned and copied to target server.
Step 2(Untar the binaries in target server)
Login to devdb13
Oracle 22.214.171.124 binaries
or move the oracle_11204_binaries.tar file if you need to.
Step 3 (create the clone script)
clone.sh #!/bin/sh echo
"Clone started at `date`" | tee -a clone.log perl
ORACLE_HOME_NAME=OraDb11g_home4 '-O"LOCAL_NODE=devdb13.acsrr.com"' echo
"Clone ended at `date`" | tee -a clone.log
Step 3 (Clone the binary)
Here is the cloning log screenshot, We need to execute root,sh as requested in the log file.
Unix Admin can run the root.sh as a root user. Unix admin can
also provide sudo privilege to oracle account and DBA can run
Here is the log for executing root.sh.

following environment variables are set as:
the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...
will be added to the /etc/oratab file as needed by
