Does ObjectDB has a similar feature like Oracle Database Change Notification ?

Hi,

I am evaluating ObjectDB because its JPA/JDO features, I am wondering is there a similar feature like Oracle Database Change Notification( http://docs.oracle.com/cd/B19306_01/appdev.102/b14251/adfns_dcn.htm ), with which multiple application servers can get notified when something changed in database.

Thanks.

Update notifications are supported by ObjectDB based on JPA lifecycle events.

But these events are fired only in the application that causes the update, so in order to have a cross server notification mechanism, your application has to set listeners for these events and then notify other applications and servers.
