Preventing Transaction Timeouts

[jacques_buitendag]

Hi all,

I am writing an application that requires that there are long running transactions.

The problem comes in that the transactions time-out after 3 minutes (or any other value I set the time-out to). The time out happens every time even with the application performing the required operations.

My question is does JBoss only use a time to determine if a transaction is still active or does JBoss monitor the activity in the tread associated with the transaction ?

I am using JBoss 3.2.1 and JDK 1.4.2

Kind Regards

It's a timer that eventually times out the transaction (with default settings after 300 seconds), activity of the thread is not measured (how would you do that in Java?)

Hi Juha,

That was what I thought!

My hope was that Jboss would at least reset the timer if it found the thread still active!

I know that it is properly impossible to monitor thread activity in Java but a simple solution would have been each time the thread make a successful call to a EJB (or any application server controlled resource) the timer could be reset, this wont happen if the call causes deadlock between two transactions.

I think this would have worked because the call is intercepted by Jboss
