500Mb ObjectDb database opening issue

Hi, I have observed that 500 Mb objectDb database opening time is very slow (~3 seconds) for following code m_EntityMgrFactory = Persistence.createEntityManagerFactory( "objectdb:" + aFilename ); m_EntityManager = m_EntityMgrFactory.createEntityManager(); Does exist any way to speed-up open time for big databases? Definitely, it's too long for 500 Mb database! ... results="64mb" programs="500" />   <extensions drop="temp,tmp" memory="mem" /> </database> <entities>   ... results="64mb" programs="500" />   <extensions drop="temp,tmp" memory="mem" /> </database> <entities>   ...

I have one "consumer" process which reads messages from the queue database and inserts these into an embedded "normal" objectdb database. This is the process which has generated the OOM exception.

mapping file is not being loaded

Hi, I am evaluating ObjectDB by using it with an in-house developed library in order to prototype its capabilities / performance. I am having a problem in that the in-house library in question reads a simple configuration file to determine available persistence units, and then bootstraps them using the JPA Persistance.createEntityManagerFactory() method and passing in the persistence unit name (again, obtained from the configuration file ). ... value = "objectdb://localhost/db/test.tmp;drop" /> <property name = "javax.persistence.jdbc.user" ...
