Question

我们正在使用tdspool并尝试在同一台机器上使用tsql连接到它。 tdspool似乎打开了它的连接就好并且开始监听但是连接到池的任何客户端都超时了。

pool.conf

[global]
        min pool conn = 5
        max pool conn = 10
        max member age = 120

[sampool]
        user = [REDACTED]
        password = [REDACTED]
        database = [REDACTED]
        server = [REDACTED]
        port = 1313 ;change to a non standard port so we can see the connection details in the debug log

当使用tsql连接到127.0.0.1:1313时，tdspool输出只是说“接受连接”而没有别的。 freetds.log输出以下内容：

我有类似的问题。将尽力帮助您解决问题。首先，确保您的/etc/freetds.conf包含有效配置：

[global]
tds version = 4.2 
...
[myserver]
    host = <ip>
    port = 1433
    tds version = 4.2 < this is important

现在，/ etc /tdspool.conf

 [sampool]
 user = [REDACTED]
 password = [REDACTED]
 database = [REDACTED]
 server = myserver < important
 port = 1313

然后tdspool sampool应该开始了。我的错误如下： 1.我认为pool.conf中的服务器是服务器的ip或域，而实际上是freetds.conf中对服务器的引用 2.在freetds.conf中我使用了错误的（太高）tds版本。 Tdspool支持最高4.2的tds版本，如他们的文档中所述。

现在，如果您尝试通过tsql -S 172.0.0.1:1313进行连接，您仍将永远“接受连接...”。但是，如果你这样做

tsql -S 127.0.0.1:1313 -U <username> -P <password> -D <database>

您将通过tdspool连接并能够对您的sql server运行查询。

Answer 2

软件错误

我们去了官方邮件列表，并逐字询问了这个问题。答案似乎是没有人不重写当前的项目。

使用客户端库并进行了充分测试，但池和服务器都是   真的不是很好。

tdspool的当前状态是....它编译！我并不感到惊讶   运行不正确。

那说它是开源的。欢迎任何帮助/建议/补丁。

我们花了相当多的时间来弄清楚我们做错了什么，所以这是一种痛苦。虽然我打算制作/修改现有的SQL Server池，但我很失望FreeTDS（一个很棒的项目）带有这样一个不稳定的池
