我正在尝试通过 IBM DB2 将 derby 数据库与 C# 应用程序连接起来。
起初，我安装了 IBM Data Server Driver Package，根据以下 url 中给出的文档，
http://www.ibm.com/developerworks/data/library/techarticle/dm-0410ng/index.html。
然后我安装了IBM Data Server Client，它在“bin”目录中有这个dll，我将它添加到系统路径中。并按照该文件执行每个步骤
但我收到错误
{System.Data.Odbc.OdbcException (0x80131937): ERROR [08001] [IBM][CLI Driver] SQL30081N A communication error has been detected. Communication protocol being used: "TCP/IP". Communication API being used: "SOCKETS". Location where the error was detected: "xx.xx.xx.xx". Communication function detecting the error: "selectForRecvTimeout". Protocol specific error code(s): "0", "*", "*". SQLSTATE=08001
和错误堆栈跟踪为
