stress test -> com.objectdb.o.InternalException: null

I am running a stress test with 2 users, each making a request to the JSON API (which uses as storage ObjectDB) each 50 milliseconds. An API call might have between 1-4 db calls, but they are relatively light, and the db has just a few MB at the moment. After a few minutes I got this exception. If I decrease the load, it doesn't happen. If I increase it, I get it very often. Any solution/fix? A sample project is very hard, if not impossible, to create, because it uses all the system.

Should I use ObjectDB and JDO?

My application is not meeting required performance because JavaDB appears to be my bottleneck.  I require a faster DB.  Surveying the Internet lead me to believe that ObjectDB might be just what I am looking for (to achieve MUCH faster database access).  But, I have a few concerns.   #1 2016-07-09 15:19 My application is not meeting required performance because JavaDB appears to be my bottleneck.  I require a ...

Activation key causes database to not start

We had ObjectDB version 2.5.7_06, then we bought a server license, then we activated it today. We get an error when trying to start ObjectDB after adding activation in objectdb.conf. We initially thought it's because it was an old version, so we upgraded to 2.6.5_04, but without success. We still cannot start ObjectDB if we add the activation key in objectdb.conf. This is the ObjectDB log we get when trying to start ObjectDB with the license. What is to be done? Thank you. :) #1 2016-01-16 12:01 We had ObjectDB version 2.5.7_06, then we bought a server license, then we activated it today. We get an ...

Is it possible to commit only specific elements?

Hello, As stated above, I would like to know if it is possible to commit only specific elements, or at least update a single table, disregarding the other entities loaded in the persistency context? I have a complex hierarchy of intertwined objects. Currently I am clearing my persistency context, retrieving only the needed ones, creating new ones (which I want to commit), detaching the ones I've previously retrieved and finally committing. My context is big data and performance is an issue.      #1 2015-07-24 11:13 Hello, As stated above, I would like to know if it is possible to commit only specific elements, or at le ...
