Check the oracle home size
[oracle@lnx1 ~]$ cd /oracle/app/product/11.2.0/dbhome_1
[oracle@lnx1 dbhome_1]$
[oracle@lnx1 dbhome_1]$ du -h . | tail -1
4.5G .
Create the directory tree on the remote server and change ownership to oracle
[oracle@lnx2 ~]$ su -
Password:
[root@lnx2 ~]# mkdir -p /oracle/app/product/11.2.0/dbhome_1
[root@lnx2 ~]# chown -R oracle:dba /oracle
On source execute tar command to copy over the network the oracle_home directories to the target server
[oracle@lnx1 ~]$ cd /oracle/app/product/11.2.0/dbhome_1
[oracle@lnx1 dbhome_1]$ tar cvf - . | ( ssh lnx2 "cd /oracle/app/product/11.2.0/dbhome_1 ; tar xvf -" )
Once the tar finishes to copy on the target oracle home check the total size
[oracle@lnx2 ~]$ cd /oracle/app/product/11.2.0/dbhome_1
[oracle@lnx2 dbhome_1]$ du -h . | tail -1
4.5G .
Using the OUI to finish the cloning process
First I need to detach the inventory because the server was itself a clone of the source
[oracle@lnx2 ~]$ cd /oracle/app/product/11.2.0/dbhome_1/oui/bin
[oracle@lnx2 bin]$ ./runInstaller -detachHome
ORACLE_HOME="/oracle/app/product/11.2.0/dbhome_1"
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB. Actual 1992 MB Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /home/oracle/oraInventory
'DetachHome' was successful.
Once the inventory was detached from the old server version I can run the
cloning procedure:
[oracle@lnx2 bin]$ ./runInstaller -clone -silent -ignorePreReq
ORACLE_HOME="/oracle/app/product/11.2.0/dbhome_1" ORACLE_HOME_NAME="dbhome_11gR2"
