Abstract
Abstract. Active XML (AXML) provides an elegant platform to integrate the power of XML, Web services and Peer to Peer (P2P) paradigms by allowing (active) Web service calls to be embedded within XML documents. In this work, we present some interesting aspects encountered while investigating a transactional framework for AXML systems. To be more precise, we discuss the following: (a) Locking protocol when the structure of both, data and transactions, are nested. (b) Dynamic construction of the undo operations, and an algorithm to compute the correct undo order in the presence of nesting and parallelism. (c) To overcome the inherent problem of peer disconnection, we propose an innovative solution based on “chaining ” the active peers for early detection and recovery from peer disconnection. 1
