UserException: Invalid configuration in 'internal' - Check permissions

Hi all,   I have a master/slave code so that each slave reads a subset of points of the same database. ObjectDB entities do not allow serialization and so I have sent, to each slave, the file path. With such information I have tried to create an entityManager, in each slave, as follows: EntityManagerFatory entityManagerFactory = Persistence.createEntityManagerFactory(filePath); EntityManager = entityManagerFactory.createEntityManager(); However I get the following error ... the server and the node have permission to read and write in the output folders. Should I change any configuration from the node ...

First query takes 4+ minutes to complete

Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application. We observed that in our case it takes on average more than 4 minutes to complete the first SELECT query that we run on the DB which contains about 320,000 records of a single type of object. SQLite in comparison responds within few seconds on average with the same number of records. We hope to receive your recommendation on how to improve this result with this post.   Test System ... sync = "false" path = "$objectdb/" mode = "write" /> <locking version-check = "true" /> ...

So, we'd like to embedded odb into each instance instead for now and point each to the same database folder, however I've got a few questions I couldn't find answers for: ... always have a SPOF with odb server due the master-write only limitation. Is there a way to spawn multiple server instances ... Multiple processes cannot write to the same ObjectDB database concurrently. Future versions may remove ...
