增量同步失败报错，关键词“The replication slot does not exist and the task is not started for the first time.”

场景描述

增量同步期间DRS任务报错，日志提示信息：service LOGMANAGER failed, caused by: The replication slot does not exist and the task is not started for the first time.

可能原因

源库逻辑复制槽已经被删除，DRS无法从源库获取到和当前同步位点接续的日志。

解决方案

由于DRS无法从源库获取到和当前同步位点接续的日志，需要重新创建DRS任务进行同步。
