ObjectDB Manual

Hello,I would like to be able to read or refer to the ObjectDb manual (v2) on my Kindle. Unfortunately, I didn't find any option to download the manual, either as a .pdf (most convenient)or as a zipped set of .html files (a single file would be better for an easier conversion to .pdf) Is there such an option I'm unaware of on your website or could you make the manual available for offline reading?Very best regards,Paul...

[Explorer] Editing Database Files

Some features of ObjectDB 1 Explorer have not been implemented yet in the new Explorer of ObjectDB 2. The new Explorer of ObjectDB 2 is currently a viewer rather than editor, and database files are always opened in read only mode.

persistence.xml classes not respected by ObjectDB

Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ their embeddable classes). P2 is created properly, but P1 gets all entity classes (from P2 also). How can this be avoided, so that both P1 and P2 get just the classes that were specified to each? There is no place in code where P1 tries to access classes from P2, so it makes no sense. ...

stress test -> com.objectdb.o.InternalException: null

I am running a stress test with 2 users, each making a request to the JSON API (which uses as storage ObjectDB) each 50 milliseconds. An API call might have between 1-4 db calls, but they are relatively light, and the db has just a few MB at the moment. After a few minutes I got this exception. If I decrease the load, it doesn't happen. If I increase it, I get it very often. Any solution/fix? A sample project is very hard, if not impossible, to create, because it uses all the system. ...

Performance problem

Hi, we have a strange performance problem with ObjectDB 2.5.3_01 and JBoss 7.1.1. We have two ObjectDB databases on one ObjectDB server. Production database is running 5-10 times slower than test database. Their size and number of records are almost identical. When running production database in separate test environment its speed is very good. We did a performance analysis on our 2 linux servers one running JBOSS and other running ObjectDB. - CPU utilization of JBOSS server is max 5-10% (per core)...
