Server vs embedded mode in multi-instance scenario

We are creating a web app that will have multiple different clients, each on their own EC2 instance(s). The clients do not need to share any data, so each could have its own ObjectDB. Clients have a user base of about 2,000 to 60,000 users that could possibly be using their application at any given time (100k absolute maximum). We will probably have multiple instances per client for availability concerns as well as auto scale during peak usage, at least for the benefit of our web application if not for objectdb. #1 2013-01-18 22:18 We are creating a web app that will have multiple different clients, each on their own EC2 instance(s).

Problem on JPA Merge Entity.

Hello, I have a problem with the EntityManager.merge() function. I set a property value of an entity (statement) with an other entity (newSingleConstraint). newSingleValue is already persisted. I do this myself (no use of cascade because sometimes the newSingleValue is already in database).   The statement update don't throw exception. And when i try to reload statement the value i have set before is a null value. I check with the Explorer, the statement has a null value on the property and the newSingleValue is present. #1 2011-02-03 16:57 Hello, I have a problem with the EntityManager.merge() function.

java.sql.Time field off by 30 minutes

Hihi, I'm wondering if this is a bug. I have a simple entity with java.sql.Time field. On writing and readback, the field is found to be 30 minutes off. It is observed on objectdb explorer as well.

InternalError on query of empty database

Hi, I have reasons for sometimes trying to query the database before anything has been created. The problem is the database throws a InternalException when that happens. Is it possible to throw something that identifies that that is the issue, say something like "MissingSchemaException", ie something that clearly shows its because no data of that type has been added? This just makes the exception catching cleaner. Thought thinking about it, it probably needs to be a JPA exception, maybe something like javax.persistence.EntityNotFoundException? #1 2011-07-21 01:39 Hi, I have reasons for sometimes trying to query the database before anything has been created.
