Document:

Web Services Atomic Transaction (WS-AtomicTransaction)

Purpose:

To handle a two-phase commit process, including the following steps:

1. Services register with a coordinating service, as described in relation to WS-Coordination.

2. Each registered service attempts to update a database. Even if an update is successful, changes are not committed.

3. In response to a poll conducted by the coordinating service, one of two outcomes occurs:

   • Each registered service responds to the coordinating service and indicates that the changes were successful, in which case the coordinating service issues a commit directive to all resource managers that were involved in the transaction.

   • Alternatively, if any service fails to respond or if any response indicates a failure, the coordinating service issues a rollback directive to all the resource managers.

   WS-AtomicTransaction also can be used to ensure the integrity of data in memory.
