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. ... lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in the new created ...

ODB should auto-restart if it detects it's necessary

Hi! I find very tricky the need to restart ObjectDB server after schema modifications in a distributed environment. Moreover, not doing it does sometimes trigger ugly errors, which mean application downtime. It might be very useful to have an additional feature (that could be enabled/disabled in objectdb.config) that each time ObjectDB detects a schema change that requires restart, it should automatically restart itself. This way we save a lot of headaches from our dev. ops. Currently we have to manually do: ... lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in the new created ...

Indexing a field results in internal Exception

I have an application that I have been converting from JPA/MySQL to JDO/ObjectDB and I have hit a problem with indexing. An index on a String field is required to give good performance but if I add the @Index annotation to the field I eventually end up with an ObjectDB internal exception.  This is reproducible, as is the program running to completion (slowly) if I remove the @Index annotation.  Is there anything I can look for that might result in this exception? ... lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in the new created ...

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.... lines (e.g. Java code , stack trace ) - select a style in the toolbar and then insert the text in the new created ...
