Please look in /app/erpdev2/oraprod/db/tech_st/10.2.0/appsutil/log for logs of the rapid clone which should reveal more about the errors encountered and post here.
Thanks for the reply. I created the database manually and ran autoconfig. but autocanfig is failing with below error
OCM configuration failed for ORACLE_HOME: /app/erpdev2/oraprod/db/tech_st/10.2.0
OCM configuration failed on DB tier.
You should use dbconfig instead of dbTier when cloning from a database you already created. It is trying to create the target database again.
