B2B transaction information can be stored as XML documents in RDBMS geographically distributed. In order to support fault-tolerance and persistent information storing, a deadlock free replication service is proposed in this paper. The service provides high available document retrieval against possible server failures, granting the access to the last version of the documents. It supports failures at the local manager level and at the repositories (RDBMS). The service also allows performing queries over the persistent repositories in order to recover previous commercial transaction information. Making use of this service, we propose a CORBA based centralized replication manager that ensures asynchronous passive document replication in terms of XML documents over a set of geographically distributed repositories.
