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。
