1. Re: Demand Size increases
paradisonoir May 8, 2008 4:33 PM (in response to paradisonoir)In order to add more information about my question, I should add that our environment configuration is :
Jboss Application Server (4.2.2.GA <http://4.2.2.GA> (build:SVNTag=JBoss_4_2_2_GA date=200710221140)JVM Version: 1.5.0_06-b05 (Sun Microsystems Inc.)
Using Jboss messaging and JMS with the Jboss built-in database.As I want to send a demand, I set the persistency like below in my code.
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
But what our demand is just JMS object messages which is specific to our computing domain. You can consider it as a simple JMS object message. We do not use any sort of Hibernate, but we do use Serialization in some parts. I am using the built-in Hypersonic database in Jboss without any modification in the database level. -
2. Re: Demand Size increases
clebert.suconic May 8, 2008 6:03 PM (in response to paradisonoir)It's not clear how you measure your object.
It's not clear also what are those numbers.
Messages/sec... size of those objects? what are those? -

paradisonoir May 8, 2008 7:16 PM (in response to paradisonoir)Thanks for your feedback, I hope that I can clarify them better.
It's not clear how you measure your object.
Well, that was one of my main questions how I can that. During my investigations, I became interested in knowing how Jboss folder-mainly the built-in database- changes its size as I add number of demands. Therefore, I measured the size of our Jboss folder before and after of each test case. For example, after sending 300 JMS object messages from a demand generator, we saw that our Jboss folder 2129k.b change of size. Then by assuming equation (2129/300 = 7.10k.b), each demand could be 7.10k.b.
I am not sure if this assumption can be correct or not as it is part of my question.
Messages/sec... size of those objects? what are those?
I explained the size of those objects, but for the number of messages, we have two nodes of generators and workers. Generators generates demands (JMS object messages) and workers process them and return their results. In this test case, our generator initiates and sends out 300 demands. -

clebert.suconic May 12, 2008 1:16 PM (in response to paradisonoir)All of this looks something very specific to your program.
We aways recommend to not use HSQLDB, and we don't provide support. If you want support on HSQLDB you should look at HSQL team. -
5. Re: Demand Size increases
paradisonoir May 12, 2008 1:39 PM (in response to paradisonoir)So no matter if a message is persistent or none, it should have the same demand size. Right?
If I want to use a different database, do I need to setup tables or it is easy like the hypersonic one? because I didn't change that database.
