Queries are slow on a large database

Hi, I have a 12GB database with 787603 entries. It is much larger than usual and there are performances issues. I am doing small queries and they take much longer than I expect, i.e.: Get the total number of entries Get 25 consecutive entries (i.e. 0-25) Get one specific entry On average each query needs 4 to 5 minutes to return a result. I have been adviced to use indexes but they are already used through the JDO Metadata file. For instance I use this class: ...

File lock exception on odb$

Not sure if this is an objectdb issue or not but I thought I'd raise it just in case. We had a server failure which caused an unexpected reboot. As a result, the application services which use objectdb were not shutdown properly which in turn meant we had several odb$ files left behind. I had assumed that objectdb would reprocess these when the services restarted but instead we got the exception below. ...

Unexpected Exception during commit

I'm testing code that otherwise has been working with a clean database. I have seen several examples of the following exception. It never seems to happen in the same place twice, though.

JSON serialization and __odbHidden members

Hi.. Building a REST API (Jersey-based one) I noticed that object object I serialize to JSON has a clone field with "__odbHidden" suffix, e.g.there's  "id" and "id__odbHidden" is also (unwantenly) present with the same value. In general, we can annotate fields to include/exclude them from JSON serialization, but since these fields are not declared in my classes, I have no idea how to tell marshaller to avoid them. ...
