    • A communication system (50) can include 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 can be 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 can be further programmed to perform at least one 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.
    • 通信系统(50)可以包括在对等节点处耦合到对等节点(41),源数据库(38)和目标数据库(48)的源节点(31)和逻辑单元(32或42) 。 可以将逻辑单元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,并对源节点和对等节点之间的审计进行比较。 所述逻辑单元可被进一步编程,以通过在所述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)来执行同步的功能中的至少一个,并且使用所述新目标数据库替换所述目标数据库 在同步期间检测到源节点上的关键故障时,完成同步或切换到对等节点。

    • A method and mechanism provide for online testing, replacement, upgrading and modification of portions of a radio communications system 100. A task controller 200 tests and replaces online elements in a task unit. The task unit is generally comprised of a task input queue 208, a task output queue 210, a subagent 204 and a task 206. The task controller 200 checks the functioning of the queues 208 and 210. If either or both are functioning improperly, the task controller 200 may replace one or both online. If both are operating properly, the task controller 200 tests the task 206. If the task 206 is improperly functioning, the task controller 206 replaces the task 206 with another task 402 online. The task controller 200may further replace tasks to upgrade portions of the system.
    • 一种方法和机制提供无线电通信系统100的部分的在线测试,替换,升级和修改。任务控制器200测试和替换任务单元中的在线元件。 任务单元通常由任务输入队列208,任务输出队列210,子代理204和任务206组成。任务控制器200检查队列208和210的功能。如果任一或两者都正常工作,则 任务控制器200可以在线替换一个或两个。 如果两者都正常操作,则任务控制器200测试任务206.如果任务206不正常地运行,则任务控制器206用另一个任务402在线替换任务206。 任务控制器200可以进一步替换升级系统部分的任务。
