Sql server 2008 使用FTP的SQL Server复制

我有： SQL A-发布服务器（SQL 2008 R2开发） SQL B-订阅服务器（SQL 2008 R2标准）

SQL A和SQL B位于不同的网络上，不允许直接连接

我在SQL A上启用FTP发布。 已在SQL B上创建订阅以从FTP获取文件

但由于某种原因，当我在SQL B上运行代理时，它给出了一个无法连接到SQL A的错误。嗯，是吗？当然，因为是FTP复制，所以没有连接

我做错了什么

到

sp\u addpullsubscription\u agent

命令并将

@use\u ftp

更改为

N'True'

您可以从服务器B连接到ftp服务器吗？可能存在防火墙/权限问题？不，没有权限问题。事实上，两个FTP都配置为本地。这些文件通过其他安全进程进行同步。问题是它甚至没有达到从FTP获取文件的程度。SQL B希望直接看到SQL A：（这让我很困惑。你是如何创建发布者和订阅者的？我已经用脚本更新了关于如何创建发布者和订阅者的问题。你需要在sp_addpullsubscription_代理命令中添加ftp_地址详细信息等-你使用了use_ftp=N'False'我试过了当然，我给了你一个scr的迭代ipt。但问题在第一行：exec sp_addpullsubscription_agent@publisher=N'SQL-A'我不知道该放在那里什么。如果我放'SQL-A'，不管我是否使用FTP，它都想连接到它。你试过通过management studio UI连接到订阅吗？从SQLB没有路由设置，也无法访问SQLA，反之亦然，因此management studio不会从一台服务器连接到另一台服务器。但是，这两台服务器都已启动，可以从各自的网络连接到。如果我将SQL-A放入@ftp_地址，则订阅服务器（SQL-B）要使用SSMS连接到SQL-A。2012-07-16连接到订阅服务器“SQL-B”2012-07-16连接到分发服务器“SQL-B”2012-07-16代理消息代码14080。远程服务器“SQL-A”不存在，或未指定为有效发布服务器，或者您可能无权查看可用发布服务器。
