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. ... unable to connect - is it still available with the same connection details? edit ...

Explorer in 2.3

First, the new Explorer in ObjectDB is fantastic! This is exactly what we've needed - an easy way to do ad-hoc JPQL queries and navigate through the results and even make small changes to primitive data and Strings. After playing with it for a while, here is a list of additional features I'd love to have: 1. Export of selected data: a. Simple - Select a range of cells or a column header and copy text to the clipboard or save to a file (csv, html, etc..). (There appear to be copy menu options, but I cannot get them to work.) #1 2011-10-04 20:50 First, the new Explorer in ObjectDB is fantastic!

Vacuum - Reclaiming Unused Space In Odb

I was curious if you could assist me with a challenge we are having with our objectdb database.  Our odb files are about 50Gb in size and are written to about a million times a day with both adds and updates.  This is creating a lot of unused space in the database that we are wanting to reclaim.  Other database vendors provide a vacuum process to allow dumping a database to a flat file (basically a sql dump) and reload.  Is there a capability in ObjectDb to provide a vacuum?  The online backup feature appears to copy the dead space as well so isn't performing... if the slave and master servers are running and there is a connection between them then replication will be completed. Even if there is a failure, restarting the slave and the connection to the master should complete all missing updates. You can also ...
