Following are the step by step method of cloning an Oracle 11g 11.2.0.2 Database Home from source server(ProdA) to a target server(TestA).
1. Check the patches applied on source ProdA server and the size of the oracle home directory,
[oracle@proda dbhome_1]$ opatch lsinv
[oracle@proda dbhome_1]$ du -h . tail
2. On TestA target server create directory for oracle home, change ownership to oracle user and then on source ProdA server tar oracle home and copy to destination TestA server,
[root@testa ~]# mkdir -p /oracle/app/product/11.2.0/dbhome_1
[root@testa ~]# chown -R oracle:dba /oracle
[oracle@proda ~]$ cd /oracle/app/product/11.2.0/dbhome_1
[oracle@proda dbhome_1]$ tar cvf - .
[oracle@proda dbhome_1]$ scp *.tar testa:/oracle/app/product/11.2.0/dbhome_1
[oracle@testa ~]$ cd /oracle/app/product/11.2.0/dbhome_1
[oracle@proda dbhome_1]$ tar xvf *.tar
3. On TestA target server detach the oracle home (This step is required only if the server itself is a clone/image of the source server or if oracle home was already registered in the inventory)
[oracle@testa ~]$ cd /oracle/app/product/11.2.0/dbhome_1/oui/bin
[oracle@testa bin]$ ./runInstaller -detachHome ORACLE_HOME="/oracle/app/product/11.2.0/dbhome_1"
4. Now do the cloning of oracle home,
[oracle@testa bin]$ ./runInstaller -clone -silent -ignorePreReq ORACLE_HOME="/oracle/app/product/11.2.0/dbhome_1" ORACLE_HOME_NAME="dbhome_11gR2" ORACLE_BASE="/oracle/app" OSDBA_GROUP=dba OSOPER_GROUP=dba
Once the above step is successful then execute root.sh script as root,
[root@testa ~]# /oracle/app/product/11.2.0/dbhome_1/root.sh
Finally you can check the cloned home and crosscheck the patchset level from the result seen in step 1, both will be same.
[oracle@testa ~]$ opatch lsinv
5. Post cloning steps is to accordingly update the files in $ORACLE_HOME/dbs and $ORACLE_HOME/network/admin folders.
On Windows:
After doing step 1 and 2 as above then from step 3 do the following,
SET PATH=I:\r11i\ebstestdb\10.2.0\bin;I:\r11i\ebstestdb\10.2.0\jdk\jre\bin;%PATH%
cd I:\r11i\ebstestdb\10.2.0\oui\bin
# setup.exe -clone -silent -ignorePreReq ORACLE_HOME="I:\r11i\ebstestdb\10.2.0" ORACLE_HOME_NAME="dbhome_11107" ORACLE_BASE="I:\r11i"
