BPEL: timeout behaviour of synchronous processes

Everyone who ever used a synchronous BPEL process, has seen this exception in the opmn/logs of the BPEL engine, if the process needs more time than 45s:
Failed to handle dispatch message ... exception ORABPEL-05002
Message handle error.
An exception occurred while attempting to process the message "com.collaxa.cube.engine.dispatch.message.instance.PerformMessage"; the exception is: An exception occurred during transaction completion: ; nested exception is: javax.transaction.RollbackException: Timed out

If you search for this error on forums.oracle.com, you will get an easy answer:
change the syncMaxWaitTime via BPELConsole and you are done.

But this does not help... So what parameters have to be changed, to achieve that synchronous BPEL processes do not get this timeout?
The Oracle BPEL team knows about this problem, because they have written the answer in this document in the paragraph "Troubleshooting and Workarounds". But the problem is the misleading title "Setting Properties for BPEL Processes to Successfully Complete and Catch Exception Errors".

Here a short summary what you have to do:
1.) $Oracle_Home\j2ee\home\config\transaction-manager.xml:
change the transaction-timeout parameter t1

2.) $Oracle_Home\j2ee\home\application-deployments\orabpel\ ejb_ob_engine\orion-ejb-jar.xml:
change the transaction-timeout parameter t2, t2<t1

3.) BPELConsole:
Change the syncMaxWaitTime in all domains, where you need a bigger timeout

restart the application server

Now you can write synchronous BPEL processes without getting this timeout error after 45 seconds. But be careful! You will block threads by using long-running synchronous invokes. And if many of this processes are invoked, this can stall your BPEL engine ...


  1. Hey nice post ! it help me a lot , but my problem is , that i want to catch the time out fault but the syncMaxWaitTime its not working , its on the 45 seconds default , but : i can execute a 50 seconds sync call to a web service and, i can see in the bpel console:
    “Your test request was processed synchronously. It took 50.254seconds to finish ” ,,,
    any idea why this parameter doesnt work ? i need to catch an Exception if a web service takes more than 50 seconds.
    Thanks for any suggestion.

  2. Hi Damian,

    can you please post this experience on forums.oracle.com at the BPEL forum. There we can discuss this problem easily and other people can participate...
