我在存储 PDF 文件的 Oracle 表上有一个 CLOB 字段。当我尝试将此字段导出到 Azure 上的 SQL Server Db 时，出现此错误：

但是，如果我对本地 SQL Server DB 执行相同的转换，它就可以正常工作。

我该如何解决这个问题？

我意识到，就在我将“提交大小”设置为大于 15 并在我的 TableOutput 步骤中将“使用批量更新插入”设置为 true 时，问题就出现了。

您可以尝试在客户端修改 TCP 参数：

REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v KeepAliveTime /t REG_DWORD /d 30000
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v KeepAliveInterval /t REG_DWORD /d 1000
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v TcpMaxDataRetransmission /t REG_DWORD /d 10
