The two refresh options are your best bet then.  Whenever you run a query that you wish to force to the db, just use the refresh query hint:

eclipselink.refresh=true

I do not want to disable cache completely just that the query interface should not use cache.

   There are lots of cache settings in EclipseLink.

   The simplest way to refresh from the cache is:

   1. entityManager.refresh()
   2. Our refresh query hint

   You could also disable sharing of the cache with the persistence
   unit property eclipselink.cache.shared.default = false.

          Hi,

          I am using eclipselink jpa 2.1.1, and transactional scoped
       em. When
          i merge/update an entity in one transaction and then read it
       using
          select query in another transaction, it gives me the cached copy.
          And not the one in db. How can i control this behavior from
          persistence.xml.

          I have tried     <property
       name="eclipselink.query-results-cache" value="false"/>
          But not working.



          Thanks
