First query takes 4+ minutes to complete

Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application. We observed that in our case it takes on average more than 4 minutes to complete the first SELECT query that we run on the DB which contains about 320,000 records of a single type of object. SQLite in comparison responds within few seconds on average with the same number of records. We hope to receive your recommendation on how to improve this result with this post.   Test System #1 2013-08-05 05:44 Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application. ...

ClassCastException of same object type

I have ObjectDB partially working with my project. At the moment it seems to be saving objects and retrieving objects ok in the main project. However, when I make a plugin for the project, the new objects are persisted but not retrieved.

Glassfish 4 AbstractMethodError: com.objectdb.jpa.EMF.createEntityManager

Hi! I've been trying to get Glassfish 4 (Java EE 7) work with ObjectDB the whole day. It seems to be an error. The same code (adapted to Java EE 6) works perfect in Glassfish 3.1.2.2. I attached the samples as NetBeans projects, so that you could check easier. 1 for GF3 (6) and 1 for GF4 (7). Thanks! #1 2013-07-04 19:17 Hi!

Out of Memory - Slow leak?

This is a continutaion of Issue 61 - unfortunately it doesnt seem that the fix in 2.2.9_03 has fixed the problem. The scenario is still the same: I have two "producer" processes which insert messages into an objectdb "queue" database running with an objectdb server process. 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.

A lot of ENT and SIV instances which are not cleared by GC

Hello. I have a JSF application (Glassfish 4, Java 8, ObjectDB 2.6.0). In some time the heap is getting 95% full with java.lang.OutOfMemoryError: GC overhead limit exceeded.  The first screenshot from VisualVM shows used heap during a 1000 requests stress test. The second shows that after this test there are many com.objectdb.o.ENT and com.objectdb.o.SIV instances. Why isn't it cleaned? I use simple EJB managers containing EntityManagers. On bean's PreDestroy and in servlet's i make entityManager.clear(); #1 2015-02-21 17:33 Hello. I have a JSF application (Glassfish 4, Java 8, ObjectDB 2.6.0).

Querying error - java.lang.ClassCastException: com.objectdb.o.STV

I'm getting the ClassCastException below when querying objects. As yet I haven't been able to track down the exact circumstance in which it occurs - saving and querying objects works fine on attempts to recreate - but presumably at some point an object gets saved which objectdb doesn't like. Any pointers as to what is wrong or approaches to investigate further would be much appreciated. Bug Version: 2.0.5 Priority: Critical Status: Fixed Replies: 6 Type:  Bug ...
