When running adcfgclone on database node we had three modes in which it can be executed.
 
perl adcfgclone.pl dbTier
 
 It will configure the ORACLE_HOME on the target database tier node and  recreate the controlfiles.
 This is specially used in case of standby database and/or hot backups. It will take care of all the steps. 
 
perl adcfgclone.pl dbTechStack
 
It will configure 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.
 
perl adcfgclone.pl dbconfig
 
It is used to configure the database with  context file.Database should be in open mode.
 
cd $RDBMS_ORACLE_HOME/appsutil/clone/bin
perl adcfgclone.pl dbconfig target_context_file
Where Target Context File is:
$RDBMS_ORACLE_HOME/appsutil/target_context_file.xml
