Need help to analyse very high memory usage by objectdb (PRU, SEV, VAL[])

Hello, we have a useCase in which we consume too much memory and run into a "GC overhead limit exceeded" exception. Nearly 90% of the memory are taken by com.objectdb.o.PRU (49%) com.objectdb.o.SEV (29%) and com.objectdb.oVAL [] (9%). When debugging, we did not get the reason for the high memory consumption yet. Can you give us any any hints, which leads to the generation of these objects? We assume that we (erroneously) refer to too many entities in the memory. #1 2016-12-06 16:47 Hello, we have a useCase in which we consume too much memory and run into a "GC overhead limit exceeded" ...

Problem with distinct select, order by and equivalent alias/attribute path

Hi, while working with a (standard-)JPA-query generating framework we run into an exception when ordering the results of some projection when the order by expression is different (though logically equivalent) to the projection expression. Here is the example: ... by the library user (the developer). Maybe you can change your query building to produce a different query? ... it seems to make no difference in the resulting query if I change the construction of the QueryDSL-expressions and the order by clause is ...

Empty query results after JAR creation

Hi, I struggle with a strange issue. I've embedded ObjectDB in a small application to query cases. Within Netbeans everything works fine but when I create a  JAR File and executed via "Java -Jar xyz.jar", I get either empty results or on some cases a "NoResultException" which appears to report the same issue. I've created a small test case (attached zip file) with sample DB to reproduce the issue.  #1 2012-04-24 04:03 Hi, I struggle with a strange issue.

ObjectDB eclipse plugin

Hello, Creating an eclipse plugin from the downloadable objectdb.jar file DOES NOT work in the eclipse OSGi environment (at least that is my experience). Could we have a genuine eclipse plugin from ObjectDB that works? You already have a pluging that integrates Objectdb with BIRT, so it seems it should not be difficult. The downloads could now have both the eclipse plugin as well as the usual jar. Let me know what you think.   Thanks #1 2011-07-14 18:30 Hello, Creating an eclipse plugin from the downloadable objectdb.jar file DOES NOT work in the eclipse OS ...

objectdb.conf Information

Hello, Is it possible to get detailed information on objectdb.conf client vs server? We do have an objectdb.conf for our client and one for our server instance. Now there're several questions: - Which config entries are relevant for the client and which one for the server? I.e. what about: <cascade-persist always="true" on-persist="false" on-commit="true" /> we want to activate enhancer agent, guess this is client right? activation-code - guess this is required for server only right? #1 2011-11-11 10:15 Hello, Is it possible to get detailed information on objectdb.conf client vs server?
