What are high level important steps in R12.2 cloning process

Q What are high level important steps in R12.2 cloning process? 

PART 1 : PREREQUISITE TASKS
– check for in-progress online patching cycle

PART 2 : PREPARE SOURCE SYSTEM

perl adpreclone.pl dbTier
perl adpreclone.pl appsTier

**require Apps User password and Weblogic AdminServer password
In 12.2, the adpreclone.pl process on the application tier creates a complete compressed archive of the Oracle Fusion Middleware and its components

PART 3 : COPY APPLICATION TIER NODE

Copy Application Tier node from the Source “Run Edition File System” to the Target “Run Edition File System”.so if source run edition is fs2, then target run edition will also be fs2
Only copy “EBSapps” directory from under $RUN_BASE. DO NOT COPY “inst” or “FMW_Home”

PART 4 : COPY DATABASE TIER NODE

Do normal RMAN cloning

PART 5 : CONFIGURE TARGET DATABASE SYSTEM

SQL> exec fnd_conc_clone.setup_clean;

$ perl adconfig.pl dbTier

PART 6 : CONFIGURE TARGET APPLICATION SYSTEM
——————————————–
$ perl adcfgclone.pl appsTier

RUN ADPRECLONE ON RUN EDITION <<< NEW STEP IN R12.2
COPY TARGET RUN EDITION OVER TARGET PATCH EDITION <<< NEW STEP IN R12.2
RUN ADCFGCLONE ON TARGET APPLICATION NODE PATCH EDITION <<< NEW STEP IN R12.2

PART 7 : FINISHING TASKS
————————-
Update profiles, workflow settings, SESSION_COOKIE_DOMAIN, SSL and SSO configuration as required
Changing SYS/SYSTEM/APPS/SYSADMIN/OTHER ORACLE passwords as per business requirements

Q In the cloning process, when do you utilize dbTechStack vs just dbTier?
perl adcfgclone.pl dbTechStack vs perl adcfgclone.pl dbtier

There are different components with RapidClone that are used when cloning an Oracle Applications instance. These are:

dbTechStack (RDBMS ORACLE_HOME)
database (database only, including control file creation)
dbconfig (database only, with no control file creation)
dbTier (both dbTechStack and database)

atTechStack (Tools and Web ORACLE_HOMEs)
appltop (APPL_TOP only)
appsTier (both atTechStack and appltop)

perl adcfgclone.pl dbtier

This will configure the ORACLE_HOME on the target database tier node + recreate the control files. This is used for cold backup.

perl adcfgclone.pl dbTechStack

This will configure the ORACLE_HOME on the target database tier node only. When running this command, you will have to recreate the control files manually.
This is used to clone the Database separately, for example using RMAN hot backup.

When you use “dbTier” option, the perl script will configure both the tech stack and data stack(ORACLE_HOME and Oracle Database)

whereas “dbTechStack” option will only configures ORACLE_HOME and it WILL NOT create database, and this is generally used while doing hot clone where db creation is a manual step.
