title: using multiple JPA Entity manager with single database
body: <p>I have the following setup,
  Client &lt;--> Web &lt;--> Multiple Data Services with Hibernate (in different server) &lt;--> Database</p>
  
  <p>Is this setup possible? (multiple Hibernate instances for single DB). If so if I enable cache at Hibernate side, how the correct data will be retrieved? Because in one of the server the old data might be cached.</p>
