ObjectDB Database Search

Hi, we have a strange performance problem with ObjectDB 2.5.3_01 and JBoss 7.1.1. We have two ObjectDB databases on one ObjectDB server. Production database is running 5-10 times slower than test database. Their size and number of records are almost identical . When running production database in

far as I can tell, my unit test is pretty much identical . Not sure why this doesn't work. Thanks

The DB Explorer cannot be opened after schema package renaming of entity types because it seems that deprecated entity types which are removed from our java project break the database. In the database the entity types and deprecated entity types can be part of the identical package. The schema

I don't think JDO supports altering an entity's Application Identity .  Does ObjectDB? @PersistenceCapable public class MyClass implements Serializable, Cloneable{ @Id private StringIdentity id; ... }   PersistenceManager persistenceManager = ...; Transaction transaction

Hello, it is possible to recover an entity that has been removed automatically by CascadeType.Remove. After cascade remove the removed entity will be persisted with the identical primary key. Are all broken references in other entities on this removed/persisted entity repaired again? best regards
