Can I run adadmin to regenerate the missing class file:
4. Reload JAR files to database
Reload JAR files to Database will reload your jar files from 10.1.2 and 10.1.3 ORACLE_HOMEs on your apps node.
We are missing some jar files under to be loaded from RDBMS_HOME on db node.
Please try action plan suggested and you should be fine. Also, I suspect, your RDBMS_HOME binaries are not cloned. Can you compare patches in prod and destination env for your RDBMS_HOME and check for missing patches.
