The development of new web services by composition of existing services is becoming an extensive approach. This has resulted in transactions that span in multiple web services. These business transactions may be unpredictable and long in duration. Thus they may not be acceptable to lock resources exclusively for such long period. Two-phase commit is also not suitable for transactions with some long sub-transactions. Compensation is a way to ensure transaction reliability. However, rolling back a previously completed transaction is potentially expensive. Thus, tentative holding is another option. This paper presents a transaction management model for web service composition. We apply the approach of tentative hold and compensation for the composite transaction. We also present a multi-dimension negotiation model for the service composition.
