Editing Tuxedo (software) (section)

===Transaction monitoring and coordination===
Tuxedo applications can request that all service invocations and their associated updates to any resources controlled by resource managers (such as databases) be controlled by a transaction.  Once the application begins a transaction, all subsequent service invocations and nested invocations are included as part of that transaction, even those services that were executed on remote domains.  Tuxedo then coordinates the commit processing with the resource managers to ensure atomic updates to all affected resources.  Transactions can be controlled by the application or automatically controlled by the Tuxedo configuration, i.e., container managed transactions.
