Transaction | X4Documentation

	`Transaction`: Executes process steps as transactions: A commit causes all operations to be performed persistently on the target system, and a rollback causes all operations to revert to their original state prior to the transaction. To encapsulate process steps into a transaction, place the corresponding transaction components before and after the process steps. In most cases, the transaction component is used for JMS queue operations and for database operations.

Please observe the following notes:

Transactions do no work in the X4 Designer’s debug mode.
Transactions only work if the JNDI name of the datasource is provided.
From within a transaction, you can execute subprocesses.
If a subprocess is started from within a transaction using the Process Starter adapter, the transaction does not apply for this subprocess (transactions do not work throughout threads).
It is not possible to nest transactions in transactions.
In a transaction, you can use multiple database connections and JMS queues.
The used database connection (JDBC DataSources) must support transactions.
In order to execute transactions, the jta attribute must not be set to false when configuring the data source to be used within the standalone.xml.
