Run out of memory

Hi, I've been looking into ObjectDB for our use, where everything has been great apart from I'm stuck on the following problem.   I am trying to load a large file (> 1GB), process certain information and store it back in the database to access / modify later. I require to be able to rollback changes as well, where there can be massive amount of changes.   #1 2011-06-21 01:43 Hi, I've been looking into ObjectDB for our use, where everything has been great apart from I'm stuck on ...

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 ...

Compare old and new schema

Hello, I have an old database file with important data. Over time, I have modified some of the entity classes but did not keep track of the changes. Some fields may have been renamed or removed, some classes may have been renamed or changed package. Is there a way for me to check what "format" the entity classes have in the old database file and compare that with the new classes definitions?   Thanks, farid #1 2015-02-13 13:10 Hello, I have an old database file with important data.

Roadmap - no progress - any plans - transparency?

Hi! I have been using ObjectDB for some time, and I'm relatively glad about it. What I'm not so satisfied is that there is no road map for ObjectDB. We see bug fixes and minor adjustments, which is great, but there's nothing about the future. We need to know in which direction ObjectDB is heading, and if it's heading anywhere or just staying in this state forever, as I see it. It would be nice to have more transparency about this topic. I know there are feature requests already made, but they seem to be ignored. #1 2014-05-11 19:51 Hi! I have been using ObjectDB for some time, and I'm relatively glad about it. What I'm ...

auto-generated uuid fields

Hello, we're porting a JDO application to ObjectDB which uses uuid-hex generated values. However the page on generated values in your JPA tutorial only mentions numeric generated values, and when we try to use it the error message seems to imply that auto-generating strings isn't supported. Could you confirm whether this is the case? If so it seems an odd omission, given that it's part of both the JPA and JDO standards (JPA Generator.UUID_HEX and JDO value-strategy="uuid-hex") and that the Java language itself supports it (java.util.UUID). JDO Feature Version: 2.4.7 Priority: Normal Status: Active Replies: 5 Type:  JDO Feature ...

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 #1 2017-09-22 21:07 Hi, I seem to have a frequent issue with my Filename.odb$ remaining in my /db directory after my program ...
