mapping file is not being loaded

Hi, I am evaluating ObjectDB by using it with an in-house developed library in order to prototype its capabilities / performance. I am having a problem in that the in-house library in question reads a simple configuration file to determine available persistence units, and then bootstraps them using the JPA Persistance.createEntityManagerFactory() method and passing in the persistence unit name (again, obtained from the configuration file ). #1 2012-06-22 15:00 Hi, I am evaluating ObjectDB by using it with an in-house developed library in order to prototype its capabilitie ...

Occasionally slow requests in load testing

We are running load testing against objectdb version 2.3.7_18. The performance is generally OK, however there are quite a few "spikes" in the performance where we are getting a lot of very slow response times from the DB, around 10 - 15 seconds. Looking at the DB server process with AppDynamics we can see that most of the requests get stuck in one of 2 places: com.objectdb.o.PGC:w: line number 232 com.objectdb.o.LFL:U: line number 1068 Please see the attached callgraph examples for full stack trace examples. #1 2012-04-26 12:56 We are running load testing against objectdb version 2.3.7_18.
