Doctor - high memory usage

Hi, Is it possible to reduce Doctor memory usage? Right now for recovering 67MB database, I need to set heap space to at least 450MB. Even then whole process takes ages. Optimal setting for this database is about 650MB. It's about ten times of size of database. #1 2011-03-22 22:08 Hi, Is it possible to reduce Doctor memory usage?

Filename.odb$ Persisting Issue

Hi, I seem to have a frequent issue with my Filename.odb$ remaining in my /db directory after my program terminates which prevents me from running my program again due to a persistence error thrown by Eclipse. I can't seem to manually terminate the file either. I usually have to fully close Eclipse and wait a bit for it to remove itself. Any ideas why this happens? Thanks, Dragon #1 2017-09-22 21:07 Hi, I seem to have a frequent issue with my Filename.odb$ remaining in my /db directory after my program ...

PersistenceManager.getObjectsById(Collection,boolean) throwing JDOException

I have a call to getObjectsById(Collection,boolean) that is throwing a JDOException the first time I'm attempting to retrieve an object. If I try again, then the second request succeeds. Any idea why this might occur? We're using ObjectDB 2.2.4_02. The collection being passed in is a HashSet<Object> containing a single oid object (the method is written to support multiple objects, but it seems to only be failing irregularly when only a single oid is present). I'm passing false in as the verification argument. #1 2011-05-24 21:06 I have a call to getObjectsById(Collection,boolean) that is throwing a JDOException the first time I'm attemp ...

Java 6/7 Performance Comparison

Hey, I've been using ObjectDB for a small scale home project to gain some familiarity before proposing it in a commercial project at work. What I've noticed though is that when using objectdb in embedded mode based on the console tutorial, there seems to be a bit of a performance gap running the same code between Java 6 & 7 Tracing it through I can see the bottle neck seems to be at the creation of the entity manager and I was wondering if there are any additional configuration options I may have missed while running under java 7. #1 2014-03-06 14:31 Hey, I've been using ObjectDB for a small scale home project to gain some familiarity before proposin ...

how explorer queries work

i'm curious as to how the explorer is able to execute queries when its obviously not aware of the object model that i built. the reason is because i have an application where i want to be able to execute somewhat generalized queries and i won't know what classes are in the object model ahead of time. this is especially curious to me in client-server mode since the .jar with the object model classes is on the server side, not the client side where explorer is running. #1 2012-05-02 16:09 i'm curious as to how the explorer is able to execute queries when its obviously not aware of the object mode ...
