Transaction

Transaction: Executes process actions as transaction: On a Commit, all operations are applied to the target system. On a Rollback, all operations are reset to the original state before the transaction. To encapsulate process actions into a transaction, place the corresponding transaction components before and after the process actions. In most cases, the transaction component is used for JMS queue operations and for database operations.

Please observe the following notes:

Transactions do not 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 (7.4.0-en) 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 transactional handling.
To be able to execute transactions, the jta attribute must not be set to false when configuring the datasource to be used within the standalone.xml.
