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. ... for full stack trace examples.

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....

Replicated cluster recovery

If I create a replicated database cluster as per http://www.objectdb.com/java/jpa/tool/replication what is the behaviour of the master database after a failure?

NullPointer running multiple client against server

Hi, I'm running objectdb in server mode, config as it comes out of the box. In this case the database is being used as a queue with multiple seperate processes, each with multiple threads, writing messages.

The message is made up of an id, insert-time, priority and the payload is a large string. ... To insert formatted lines (e.g. Java code , stack trace ) - select a style in the toolbar and then ...
