摘要：

Business applications, e.g., enterprise resource planning, can be hosted on distributed application servers within a multi-tier architecture. Business objects (BOs) are used as data containers cached at the middle-tier. The applications are replicated to achieve scalability and fast local access for the clients. Therefore, a synchronization of the BOs is mandatory to fulfill consistency requirements. Following the service-oriented architecture the synchronization of BOs through common services is time consuming and can be optimized. In this paper, replication strategies are presented that allow for an efficient synchronization of BOs based on profiles of BOs and of the hosting systems. A cost model based on an experimental evaluation allows to find the proper strategy. An initial configuration of the synchronization strategy can be adapted during runtime utilizing continuously updated profiles.
