Issue while configuring Hibernate 2nd level cache

Issue

• After having migrated from JBoss 5.x to EAP 6.3.2 how to configure and check 2nd level cache.
• We have some question to find out in persistence.xml file :
  • If there is a 2nd level cache configured or not ?
  • configure a 2nd level cache if not yet done and
  • check whether the 2nd level cache is working or not?
• We are using persistence.xml and an entity bean annotated by @Cache.
• When we insert :

<shared-cache-mode>DISABLE_SELECTIVE</shared-cache-mode>

into persistence.xml, the System will complains below:

cvc-complex-type.2.4.a: Invalid content was found starting with element 'shared-cache-mode'. One of '{"http://
 java.sun.com/xml/ns/persistence":property}' is expected.

• Will we want to Configure Infinispan for a JPA application or Configure Infinispan for a native Hibernate application ? Is both kind of configuration true?
• What is the right way to query the 2nd level chache about read and hit entities?
