The Organization for the Advancement of Structured Information Systems (OASIS) has announced three new services: WS-Coordination, WS-AtomicTransaction and WS-Business Activity. The services are under the umbrella of the Web Services Transaction (WS-TX) Technical Committee and will make it easier to process transactions across heterogeneous environments and coordinate distributed application action outcomes. WS-Coordination is the protocol that establishes a connection between two systems. The transaction is then handled by either WS-Atomic Transaction or WS-Business Activity, depending on the duration. WS-Atomic Transaction deals with distributed atomic transactions that utilize the two-phase commit abstract protocol, and is designed for transactions that have minimal data and are short-term. The WS-Business Activity is asynchronous and deals with longer-running activities and utilizes a compensation protocol. The protocol often consumes resources over time and individual tasks must be finished before the overall activity is complete. The three protocols address the fact that up until now Web services have allowed communication across platforms, but there has been no way to handle a multi-step transaction that has secure rollback if it fails.
