使用 T-SQL 的复制监视器信息

Mar*_*lli 13 replication sql-server-2005 sql-server merge-replication transactional-replication

下图显示了我目前正在调查的事务复制问题。

该图像来自复制监视器。

如何使用 T-SQL 获取此信息？

在此处输入图片说明

在做了一些网上搜索后，我找到了你需要的东西，希望我的回答对你有帮助。

答案 1

笔记：

它仅适用于事务性和事务性对等复制

T-SQL 脚本，可用于监视事务复制的状态以及发布和订阅的性能。

在执行以下脚本之前要考虑的事情

需要对分发和主数据库中的以下表的权限

  • MSdistribution_status
  • MSdistribution_agents
  • MS文章
  • MSreplication_monitordata
  • MSdistribution_history

在订阅服务器上安装的 DBA 数据库中创建。创建表的代码是：

            Records_In_Que numeric(18, 0) NULL,

            LogDate datetime NOT NULL,
        CONSTRAINT PK_EPR_Replication_Que_History PRIMARY KEY CLUSTERED
