High level Steps to perform R12.2 Full cloning

• Run adpreclone.pl on db tier
• Take backup of Database Tier using RMAN or conventional  process including RDBMS_TOP
• Restore/recover DB Tier using adcfgclone.pl dbTier
• Run adpreclone.pl on db tier and apps tier (RUN_BASE) using respective users
echo $FILE_EDITION  This should have output  “run”
As of Release 12.2, the adpreclone.pl process on the Application Tier creates a complete compressed archive of the Oracle Fusion Middleware and its components as follows:
o A compressed archive of the Oracle WebLogic Server home, Oracle Web Tier Utilities home, Oracle Common Utilities home and the Oracle E-Business Suite home:
<COMMON_TOP>/clone/FMW/FMW_Home.jar
o A compressed archive of the Oracle E-Business Suite Weblogic domain:
<COMMON_TOP>/clone/FMW/WLS/EBSdomain.jar
o The Oracle E-Business Suite Weblogic domain's configuration template:
<COMMON_TOP>/clone/FMW/WLS/plan/moveplan.xml
o A compressed archive of the Oracle Web Tier/Oracle HTTP Server configuration instance:
<COMMON_TOP>/clone/FMW/OHS/ohsarchive.jar
o The Oracle HTTP Server configuration instance's configuration template:
<COMMON_TOP>/clone/FMW/OHS/moveplan.xml
• For FULL Cloning we require backup of
o <APPL_TOP>
o <COMMON_TOP>
o <OracleAS Tools 10.1.2 ORACLE_HOME>

• Restore backup taken above at target
• Run adcfgclone.pl on apps Tier as show below
cd /u01/app/appdi/DR122I/fs1/EBSapps/comn/clone/bin
./adcfgclone.pl appsTier
Do you want to add a node (yes/no) [no] :
Target System File Edition type [run] :
Provide the values required for creation of the new APPL_TOP Context file.
Target System Hostname (virtual or normal) [<ServerName>] :
Target System Database SID : DR122I
Target System Database Server Node [<ServerName>] :
Target System Database Domain Name [<DomainName>] :
Target System Base Directory : /u01/app/appdi/DR122I
Target System Instance Home Directory [/u01/app/appdi/DR122I] : /u01/app/appdi/DR122I
Target System Instance Top set to /u01/app/appdi/DR122I/fs1/inst/apps/DR122I_<ServerName>
Do you want to preserve the Display [<ServerName>:0.0] (y/n)  : n

• Now we need to Clone RUN FS to PATCH FS
• Source Environment variable file at newly cloned RUN File System
• Run adpreclone.pl on RUN File system
• Copy Run File system to patch file system under FS2 (Assuming FS2 as Patch file system)
• Run adcfgclone.pl appsTier on Patch File System
cd <COMMON_TOP>/clone/bin
adcfgclone.pl appsTier
Enter the APPS password :
Enter the Weblogic AdminServer password :

Looking for incomplete CLONE record in ad_adop_session_patches table
The CLONE record status is BACKUP-FMW-HOME
Updating incomplete CLONE record to COMPLETED
• Create soft link at $HOME for users to source FS1 or FS2 Environment
• This concludes Full Standard Cloning process for E-Business Suite Release 12.2
NOTE:
If you are trying to reclone or ORACLE_HOME already registered in Inventory - you may need ot unregister ORACLE HOMEs before Cloning  you can execute the following command to unregister or detach that Oracle Home:
$ ./runInstaller -detachhome
ORACLE_HOME=<Oracle Home Location>
For Example:
$ cd $FMW_HOME/oracle_common/oui/bin
$ ./runInstaller –detachhome
ORACLE_HOME=<Oracle Home Location>
In addition to the un registration process, ensure to delete the FMW_HOME directory structure.

OR
For de-registering <FMW_HOME>/Oracle_EBS-app1:
<FMW_HOME>/Oracle_EBS-app1/oui/bin/detachHome.sh -jreLoc
<FMW_HOME>/Oracle_EBS-app1/jdk
For re-registering <FMW_HOME>/Oracle_EBS-app1:
<FMW_HOME>/Oracle_EBS-app1/oui/bin/attachHome.sh -jreLoc
<FMW_HOME>/Oracle_EBS-app1/jdk
