Tyrex failed under heavy transaction load.

[alexsong]

Hi, there,

We've tested tyrex transaction manager under havery transaction load
situation, tyrex failed after a few hours running. Here are our settings:

OS: SunOS 5.8
JBoss(jetty) 3.0.4
about 20 session beans,
15 massage driven beans,
Oracle 8.1.7
tyrex-1.0.1
(timeout 5 min)

It runs ok under normal situation, but when we issued 12
transactions/per second, after less than 2 hours, certain EJBs started
to break.

We did same loading test for built-in JBoss transaction manager, it
survives

Conclusion: Tyrex may not be very stable under heavy load productin
enviroment.

Hope this information is helpful.

Thanks

Alex Song

Even the tyrex developer doesn't recommed it for production,
which is why we no longer support it.

No wonder I couldn't find tyrex setting in jboss-service.xml in jboss 3.2.3.

Do you know if jboss team has plan to implement more sophiaticate transaction manager after jboss 4?

I read tyrex doc and src carefully, I found this guy did have very good view on how to implement TP monitoring, such as group transactions into domains, prioritize transactions to provide QoS(quality of service), control total concurrent transactions number, transaction weight measurement, transaction recovery and journal, etc. The idea does cover a fine tune transaction management framework.

Not sure if jboss has such transaction team to handle such issues.

tyrex does not have recovery/logging

Hello Alex

Bill Burke> tyrex does not have recovery/logging

Bill probably won't thank me for pointing out that JBoss does not have these either. Nor do any other open source solutions. But then you know that already. What you may not know is that Arjuna offers their transaction service integrated with JBoss. It has logging and fully automatic crash recovery. It's not free or open source, but it is lots cheaper than anything from the leading commercial application server vendors. Why not grab the free evaluation version and see if it will do the job? http://www.arjuna.com/products/jboss/

Jonathan.

[bill.burke]

which is why we partnered with you...We usually point people to you when they want a TM with recovery/logging. I forgot to do that in this case...

Apologies,

Bill
