JDO sequences from ORM file

I want to use sequences in JDO without using annotations. Normally this is done with a package-X.orm file, where X is a value passed to the PersistenceManagerFactory as the value of property "mapping". I'm encouraged to see that the JDO zip that comes with ObjectDB includes the DTD/XSD for this type of file, though I can't see a mention of it in the manual. ...

I have been adviced to use indexes but they are already used through the JDO Metadata file. For instance I use this class: ...

Filename.odb$ Persisting Issue

Hi, I seem to have a frequent issue with my Filename.odb$ remaining in my /db directory after my program terminates which prevents me from running my program again due to a persistence error thrown by Eclipse. I can't seem to manually terminate the file either. I usually have to fully close Eclipse and wait a bit for it to remove itself. Any ideas why this happens? Thanks, Dragon ...

High availability and other pratical questions

Hi,   I've just started developing a mobile app which will use a server side, hopefully handling a lot of processing and traffic. I was inteding to use TomEE+ with built-in OpenJPA and Postgres DB, initially on one master server but as it grows more master servers will be set (in different geo locations/data centers) using some data sync mechanism between them.   Now that i've met ObjectDB I want to check the option using it instead of postgres so I have few questions regarding it: ...
