Question #: 255
Topic #: 13
An XA transaction Is being configured that involves a JMS connector listening for Incoming JMS messages. What is the meaning of the timeout attribute of the XA transaction, and what happens after the timeout expires?

Suggested Answer: C Vote an answer

* Setting a transaction timeout for the Bitronix transaction manager
* Set the transaction timeout either
- In wrapper.conf
- In CloudHub in the Properties tab of the Mule application deployment
* The default is 60 secs. It is defined as
mule.bitronix.transactiontimeout = 120
* This property defines the timeout for each transaction created for this manager.
If the transaction has not terminated before the timeout expires it will be automatically rolled back.
--------------------------------------------------------------------------------------------------------------------- Additional Info around Transaction Management:
Bitronix is available as the XA transaction manager for Mule applications
* To use Bitronix, declare it as a global configuration element in the Mule application
<bti:transaction-manager />
* Each Mule runtime can have only one instance of a Bitronix transaction manager, which is shared by all Mule applications
* For customer-hosted deployments, define the XA transaction manager in a Mule domain
- Then share this global element among all Mule applications in the Mule runtime
