摘要： A communication system (50) includes a source node (31) coupled to a peer node (41), a source database (38) and a target database (48) at the peer node, and a logical unit (32 or 42). The logical unit is programmed to forward data changes from source to peer node, monitor a health status of a replication task (34 or 44) by performing an audit on the source and nodes, and compare the audits on the source and peer nodes. The logical unit is further programmed to perform among the functions of synchronizing by launching a replication task synchronization thread (52) and a new target database (54) at the peer node and replacing the target database with the new target database upon completion of the synchronizing or switching over to the peer node upon detection of a critical failure at the source node during synchronization.
摘要翻译：通信系统（50）包括耦合到对等节点（41）的源节点（31），对等节点处的源数据库（38）和目标数据库（48）以及逻辑单元（32或42）。逻辑单元被编程为将数据更改从源节点转发到对等节点，通过对源和节点执行审核来监视复制任务（34或44）的运行状况，并比较源节点和对等节点之间的审计。逻辑单元进一步被编程为通过在对等节点处启动复制任务同步线程（52）和新的目标数据库（54）以及在同步完成时用新的目标数据库替换目标数据库的同步功能中执行或者在同步期间在源节点检测到关键故障时切换到对等节点。
