On ensuring ID available after persist

This reports on a possible solution to a common problem: I was trialling ObjectDB on an existing, functioning, large JavaEE/JPA web application, which until now had used EclipseLink+MySQL and then Oracle+MySQL. On trying it out on ObjectDB I hit a problem with my very extensive entity wiring code, which relies on an "external" entity object having a non-null id after it has been passed to EntityManager.persist, thus: #1 2011-05-31 00:39 This reports on a possible solution to a common problem: I was trialling ObjectDB on an existing, functio ...

Suspected memory leak

Hi, We are running soak testing with Object DB and it is showing signs of memory leak: used memory is growing overtime until Object DB JVM fails with OutOfMemoryException. Object DB is running in a separate JVM. All the config is attached. We are continuing to investigate this and will create memory dump next time this happens. In the meantime, could you please check if there is anything wrong with our configuration? Kind regards, Natalia. #1 2012-01-22 21:46 Hi, We are running soak testing with Object DB and it is showing signs of memory leak: used memory is gro ...

Should I use ObjectDB and JDO?

Updating existing persistence entries

I have stored some instances of MyObject via em.persist(myObjectInstance); I can fetch them and bind them to a kind of property editor in my app (it simply calls the setters to reflect gui editing actions). When I try to persist a object later on, I get an error like com.objectdb.o.UserException: Attempt to reuse an existing primary key value which makes sense to me but I'm missing a em.update() method. #1 2012-12-07 19:29 I have stored some instances of MyObject via em.persist(myObjectInstance); I can fetch them and bind them ...
