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. ... from the DB, around 10 - 15 seconds.

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: ...

How force always recreate database on redeployment.

Is there some easy way to force recreation/deletion of the current database on deployment of a web application (to Glassfish). My web application uses a @Singleton @Startup bean to create and persist a test model each run. I keep getting models on top of each other on rerunning my web application. Currently, to avoid multiple models in the database, I have to undeploy from Glassfish, stop the server, delete the database file, re-start the objectdb server, re-run the web app, which is tedious. ... the database, I have to undeploy from Glassfish, stop the server, delete the database file, re-start the objectdb server, re-run the web app, which is tedious.
