System and method for efficiently synchronizing cache and persistent data in an object oriented transaction processing system |
摘要 |
A system and method for effectively synchronizing data in an object oriented distributed transaction processing system employing a multilevel data store. Each object that maintains first-level volatile data registers as a synchronization object if unsynchronized changes to that data exist. A register object at each node tracks synchronized objects registered for that node. Each registered synchronization object, in turn, registers with its superior node when registered synchronization objects are present. A hierarchy of registered synchronization objects and synchronization objects is thereby created. The transaction termination process transmits a pre-prepare message to the registered synchronization hierarchy providing each synchronization object an opportunity to flush its data to the second-level persistent data store. The hierarchical structure of registered objects ensures that the minimum number of messages are transmitted over the network.
