Cloning an Oracle home involves creating a copy of the Oracle home and then configuring it for a new environment. If you are performing multiple Oracle Database installations, then you may want to use this method to create each Oracle home, because copying files from an existing Oracle Database installation takes less time than creating a new version of them. This method is also useful if the Oracle home that you are cloning has had patches applied to it. When you clone this Oracle home, the new Oracle home will have the patch updates as well.
Note:In addition to cloning an Oracle home, you can clone individual Oracle Database installations by using Enterprise Manager Database Control. Oracle Database Administrator's Guide provides detailed information about cloning Oracle Database installations and Oracle homes.
To clone an Oracle home:
Verify that the installation of Oracle Database that you want to clone has been successful.
You can do this by reviewing the
.log file for the installation session, which is normally located in the
If you have installed patches, then you can check their status by running the following commands:
$ $ORACLE_HOME/OPatch ORACLE_HOME=ORACLE_HOME_using_patch $ $ORACLE_HOME/OPatch opatch lsinventory
Stop all processes related to the Oracle home. Refer to the "Removing Oracle Software" section for more information on stopping the processes for an Oracle home.
Create a ZIP file with the Oracle home (but not Oracle base) directory.
For example, if the source Oracle installation is in the
/u01/app/oracle/product/10.2.0/db_1, then you zip the
db_1 directory by using the following command:
# zip -r db_1.zip /u01/app/oracle/product/10.2.0/db_1
Leave out the
oradata directories that are in the
10.2.0 directory. These directories will be created in the target installation later, when you create a new database there.
# unzip -d / db_1.zip
On the target computer, change directory to the unzipped Oracle home directory, and remove all the .ora (*.ora) files present in the unzipped
$ORACLE_HOME/oui/bin directory, run Oracle Universal Installer in clone mode for the unzipped Oracle home. Use the following syntax:
$ORACLE_HOME/oui/bin/runInstaller -silent -clone ORACLE_HOME="target location" ORACLE_HOME_NAME="unique_name_on node" [-responseFile full_directory_path]
$ORACLE_HOME/oui/bin/runInstaller -silent -clone ORACLE_HOME="/u01/app/oracle/product/10.2.0/db_1" ORACLE_HOME_NAME="db_1"
-responseFile parameter is optional. You can supply clone-time parameters on the command line or by using the response file named on the command line.
Oracle Universal Installer starts, and then records the cloning actions in the
.log file. This log file is normally located in
To create a new database for the newly cloned Oracle home, run Database Configuration Assistant as follows:
$ cd $ORACLE_HOME/bin $ ./dbca
To configure connection information for the new database, run Net Configuration Assistant.
$ cd $ORACLE_HOME/bin $ ./netca
