Transaction Mediator¶
A transaction is a set of operations executed as a single unit. It also can be defined as an agreement, which is carried out between separate entities or objects. The Transaction Mediator is used to manage distributed transactions in the Micro Integrator by providing transaction functionality for its child mediators.
Info
In addition to distributed transactions, the Micro Integrator also supports Java Message Service (JMS) transactions. For more information on transactions, see Working with Transactions.
