What is the difference between dbtechstack,dbtier and dbconfig modes in Cloning?

While Cloning Oracle Applications, adcgclone can be executed in 3 Modes on Database node.


1)perl adcfgclone.pl dbTier

 It configures the ORACLE_HOME on the target database node and  recreate the controlfiles.
 This is used in case of standby database/hot backups.   


2)perl adcfgclone.pl dbTechStack 

It configures the ORACLE_HOME on the target database tier node only. Relink the oracle home.

The below steps has to be performed manually
1. Create the Target Database control files.
2. Start the Target System Database in open mode
3. Run the library update script against the Database
cd $RDBMS_ORACLE_HOME/appsutil/install/[CONTEXT NAME]
sqlplus "/ as sysdba" @adupdlib.sql [libext]
 Where [libext] should be set to 'sl' for HP-UX, 'so' for any other UNIX platform, 
or 'dll' for Windows.

3)perl adcfgclone.pl dbconfig

It configures the database with context file. Database must be open while running adcfgclone in dbconfig mode.
e.g 
cd $RDBMS_ORACLE_HOME/appsutil/clone/bin
perl adcfgclone.pl dbconfig <Context_file>

Where Target Context File is:
$RDBMS_ORACLE_HOME/appsutil/<SID_HOSTNAME>.xml
