Cloning an Oracle Home 11.2.0.4

Perform the following to clone an Oracle home:
  1. Verify that the installation of Oracle Database to clone is successful.
    You can do this by reviewing the installActionsdate_time.log file for the installation session, which is typically located in the /orainventory_location/logs directory.
    If you install patches, then check their status using the following:
    $ cd $ORACLE_HOME/OPatch
    Include $ORACLE_HOME/OPatch in $PATH
    $ opatch lsinventory
  2. Stop all processes related to the Oracle home. See "Stopping Existing Oracle Processes" for more information about stopping the processes for an Oracle home.
  3. Create a ZIP file with the Oracle home (but not the Oracle base) directory.
    For example, if the source Oracle installation is in the /u01/app/oracle/product/11.2.0/dbhome_1, then you zip the dbhome_1 directory by using the following command:
    # zip -r dbhome_1.zip /u01/app/oracle/product/11.2.0/dbhome_1
    Do not include the admin, fast_recovery_area, and oradata directories that are under the Oracle base directory. These directories are created in the target installation later, when you create a new database there.
  4. Copy the ZIP file to the root directory of the target computer.
  5. Extract the ZIP file contents by using the following command:
    # unzip -d / dbhome_1.zip
  6. Repeat steps 4 and 5 for each computer where you want to clone the Oracle home, unless the Oracle home is on a shared storage device.
  7. On the target computer, change the directory to the unzipped Oracle home directory, and remove all the .ora (*.ora) files present in the unzipped $ORACLE_HOME/network/admin directory.
  8. From the $ORACLE_HOME/clone/bin directory, run the clone.pl file for the unzipped Oracle home. Use the following syntax:
    $ORACLE_HOME/perl/bin/perl clone.pl ORACLE_BASE="target_oracle_base" ORACLE_HOME="target_oracle_home"
OSDBA_GROUP=OSDBA_privileged_group OSOPER_GROUP=OSOPER_privileged_group -defaultHomeName
    1. For example:
    1. $ORACLE_HOME/perl/bin/perl clone.pl ORACLE_BASE="/u01/app/oracle/" ORACLE_HOME="/u01/app/oracle/product/11.2.0/dbhome_1" OSDBA_GROUP=dba OSOPER_GROUP=oper -defaultHomeName
    2. The following configuration scripts need to be executed as the "root" user.
      /u02/u02/app/oracle/product/11.2.0.4/dbhome_1/root.sh
      To execute the configuration scripts:
          1. Open a terminal window
          2. Log in as "root"
          3. Run the scripts
      Example as below
  9. Oracle Universal Installer starts, and then records the cloning actions in the cloneActionstimestamp.log file. This log file is typically located in /orainventory_location/logs directory.
  10. To configure the connection information for the new database, run Net Configuration Assistant:
    $ cd $ORACLE_HOME/bin
$ ./netca
  11. To create a new database for the newly cloned Oracle home, run Database Configuration Assistant:
    $ cd $ORACLE_HOME/bin
$ ./dbca

19c ORACLE HOME Cloning -Linux/Solaris

  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 cloning 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 the Oracle home, the new Oracle home has the patch updates which is already applied on oracle home. Steps to clone an Oracle home step 1 : Stop Services Stop all processes related to the Oracle home. Step 2 : Create a ZIP or TAR file with the Oracle home (/u01/app/oracle/product/19.0.0/dbhome_1)    Use ROOT user for ZIP and UNZIP  # zip -r dbhome_1.zip /u01/app/oracle/product/19.0.0/dbhome_1 TAR option: # tar -cvf dbhome_1.tar /u01/app/oracle/product/19.0.0/dbhome_1 Step 3: s cp zip/tar to target s...
