Abstract
The prolific development of the wide variety of Internet applications forces a need for a software solution to enable access to multiple data sources while ensuring data integrity and consistency. Common Object Request Broker Architecture (CORBA) Services specified by the Object Management Group (OMG) includes a Transaction Service Specification. The Object Transaction Server (OTS) developed in this project is based on this specification. It acts as a robust system level tool to enable distributed applications to coordinate their operations into transactions. The OTS incorporates a three phase commit protocol to ensure atomicity of the transactions. This is a non-blocking protocol that ensures that operational sites participating in a transaction come to a common outcome based on the local data even in the event of (non-catastrophic) site failures.
