一次只能有一个日志读取器代理或日志相关过程(sp_repldone、sp_replcmds 和 sp_replshowcmds)连接到某个数据库。如果执行了一个日志相关过程，那么在启动日志读取器代理或者执行另一个日志相关过程之前，请删除执行第一个过程时所用的连接，或者在该连接上执行 sp_replflush。

Only one Log Reader Agent or log-related procedure (sp_repldone, sp_replcmds, and sp_replshowcmds) can connect to a database at a time. If you executed a log-related procedure, drop the connection over which the procedure was executed or execute sp_replflush over that connection before starting the Log Reader Agent or executing another log-related procedure.
