Missing Data on Retrieval (0, null values)

I try  to export all Objects in an Flatfile-Hiearchy (.csv). But only the first exported Table contains all necessary Data. Most of the others  contains all  Object-Rows', but most Values of the Columns are missing. With a  em.clear() inside the Loop, all tables are exported correctly but the Enity-Keys do not match. I can't get the point - what am i doing wrong?   emf = Persistence.createEntityManagerFactory(dbFile); em = emf.createEntityManager(); ... The result should be the same as the tables in (ObjectDB) Explorer.         ...

Object DB In memory : without Filestore

Hello, I raised this question earlier as well, we want to explore if I can run the ObjectDB completely in Memory ? (without any writes to Disk, it's okay to loose the data if the node is down ). I think that will give the best performance. The reason we are exploring is restoring state is possible for us through replaying the logs, however we want easier data structures which is really good with ObjectDB along with Concurrency controls and transaction mgmt. Let us know if it is possible to run the Object DB completely in memory without disk storage. #1 2013-10-04 07:31 Hello, I raised this question earlier as well, we want to explore if I can run the ObjectDB completely in ...

ObjectDB's Database Doctor Incorrect Error Report

Am I reading this correctly?  It seems that Doctor is telling me that one of my objects is missing.  Looking at the database with ObjectDB's Database Explorer though seems to show that the reference to the object is good and that the object does indeed exist.   Output from Doctor Diagnose and Doctor Repair is attached.  So are the two databases and screenshots of Explorer showing the reference to the object and the existence of the object. ...
