message size

[jianjia]

Hello, I am doing a MSc project in which I need to evaluate the proformance throughput of JBossMQ and JMS.
One of the test methods that I had designed is to send BytesMessage of increasing size (from 16Kb to 1Mb bytes) to JBossMQ. Unfortunately when I increased the message size to 512K, the test application is very unstable and exceptions are thrown. The error messages are mainly about OutOfMemoryError and could not store message to persistent storage. I use Hypersonic DB as Persistence Management by default, no special configuration are made. Would anybody tell me how to configure JBossMQ to accept large data quantities into PM.

Many thanks
Jianjia

My thoughts on hypersonic are probably well known if you look through these
forums.
If you really want an MSc project, try this related task:

Hi Adrian,

Thank you very much for replying my message. I have read the topic you recommended. But it did not solve my problem.

Plainly speaking, I want to send a BytesMessage with one mega bytes to and forth two queues and track the RTT(round trip time). The error messages are shown below. I changed the contents of MESSAGEBLOB here which is actually one mega bytes long.

This error occurs only when I sent 1 MB BytesMessage, I have tested with 16K, 32K, 64K, 128K... and there are no problems.
Any lucks to hear from you again?

Ask the hsqldb project why they can't serialize 1MB of data.
Or try a db that can. You'll find configs for alternate dbs in docs/examples/jms

Thank you very much for your help. I will try to find some alternative solutions myself. Cheers.

Hi,
Did u find the way to handle large message with JBOSS?

Sorry, I haven't logged into this forum for a long time. I've tested oracle with openjms, and it can accept up to 10M message. You might change a db and see if it works. Hope this help.

Thanks

Hi Jianjia,

Any chance you were trying to get messages from the Oracle Queue into JBoss? Have you successfully implemented this between Oracle and JBoss using OpenJMS?
In a project I am involved with, we are trying to subscribe to an Oracle Advanced Queue from JBoss and there aren't any clear solutions to do that. If you have done this successfully would you please point me in the right direction with some useful tips and info/links.

Kind regards,
SB
