Using explorer with a live embedded db

I want to use ObjectDB explorer with a running embedded db. This issue:  http://www.objectdb.com/database/forum/617   shows a way to do it. I followed the instructions, but still received an error when trying to connect: "...database ... currently in use by another process" I used an explorer on the same machine, trying to connect in both embedded and client-server mode. I could connect when I stopped my program that embedded the db. ... using an ordinary disk rather than a ramdisk (just as a check)? ObjectDB Support ObjectDB - Fast Object ...

Query fails with numerical values > 2^31

Hi ! I'm trying to execute the following query (from Java-code, also tried ObjectDB Explorer) delete from DataRecord p where p.TimeOfDeletion < 4147483648 This fails with "invalid numerical literal". The field p.TimeOfDeletion is of type long. As far as I know, the maximum value greater than 2^31 (Oracle: "The long data type is a 64-bit two's complement integer.") ... as well and allow 4147483648. Anyway, please check if adding L suffix to the long number (4147483648L) solves the error. ...

How to open a running db in ObjectDB Explorer?

It's not nice at all to close the application, copy the db in another location, start the application then finally I could explore my data, but it will be just a copy of the data, not the live information. #1 2013-05-25 18:08 Hi! I've just discovered that I can't see the content of a database while it's in use. Is the ...

Difficulty with the BIRT plugin

Hi, am trying to get the BIRT plugin to work. Firstly: connecting to an odb server doesn't seem to work (incompatible versions) - but there isn't any way to find out what version the BIRT plugin is using. Next: connecting directly to a file datasource seems to work, in the sense that I can ping the database, however, there doesn't appear to be any way to create a new Data Set from the Data Explorer, as suggested in the online manual: #1 2011-07-19 22:23 Hi, am trying to get the BIRT plugin to work.

JPA and handling large data sets

This is not a rellay ObjectDB problem, rather a JPA problem. Our web-based DB supports Hibernate or JPA (ElicpseLink/ObjectDB). We implemented a export/import class to export the whole database or single datasets (domains) in a persistence layer/database independent format. This class works fine - DB exports form a Hibernate/MySQL base via the independent formt to ObjectDB is possible. But exporting large binary data sets is very slow. To avoid memory problems the binary data type is read step by step during the export with the  query/setFirstResult() & setMaxResults().... and using setMaxResults may be fine. If not check if you can retrieve ranges of objects by setting both lower and upper ...
