发明名称 Methods and Computer Program Products for Efficient Conflict Detection in a Replicated Hierarchical Content Repository Using Replication Anchors
摘要 Exemplary embodiments of the present invention relate to a methodology for using replication anchors to detect conflicts within replicated hierarchical content repository. The method comprises locking a data object in the event that an operation applied on the data object is replicated from a first server to a second server, reading a transaction identifier that is associated with the data object, retrieving a transaction sequence value that is associated with the transaction identifier, and determining if a conflict situation exist by comparing the retrieved transaction sequence value with an operation synchronization anchor value, the operation synchronization value being the transaction sequence value of a last transaction from the second server to the first server, wherein a conflict situation is determined to exist in the event that the transaction sequence value is greater than the operation synchronization anchor value.
