I've had a quick read through the features/FAQ and haven't been able to find a clear answer. I'm looking at replacing a setup of H2 where I have 40GB in-memory backed by 800GB on-disk, the 40GB in memory represents the first 40GB of the 800GB on-disk for super-fast recent entry searching, the records at the end continuously purge as the new ones come in(duplicate write, one to in-memory and one to on-disk). ... to find a clear answer.

Usualy database stops once a day with no apperent reason. ... use 2.5.3_03 version and we use it in production. The same setup in test environment hasn’t have these kind of problems First ...

We have a big object tree in our project. If I use the entityManage.remove method a entityManager.refresh is necessary in order to have an updated object tree in memory. But entityManager.refresh is too slow for our project. Do you know a possibilty to remove parent/child entities without entityManager.refresh after the entityManager.remove operation? I have searched for a solution with the following unit test (See testRemoveVariant2()). But my approach works correctly. Do you have an idea? ... ;   @ BeforeClass public static void setUp ( ) throws Exception { entityManager = ...
