I need to update our backup database server when I am writing to our current database server.

So I am using two Entity Managers to handle this  and pass the same Entity.

  |         em.flush();
  |         // write to HotSite DB
  |         emTml.persist(dmvActivity);
  |         emTml.flush();

This worked fine, till I made the entity cacheable. Now I get the following error :

javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: com.cp.mvr.common.ejb.persistence.DmvColor 

Further, if an entity is set as cacheable, everytime when you do a findAll does the cache get refreshed from the database?
