客户端( win2000 server )DB2 应用程序开发客户端，VS2003
服务器端（aix 64位 DB2 8。2）
直接通过客户端我可以访问 第一次做DB2数据库，谁可以告诉我应该怎么配置了，非常感谢
using IBM.Data.DB2;
DataTable dt = new DataTable();
DB2Connection conn=DB2Connection( "= "Database=AA;uid=AA;pwd=AA; ");
string sql= "select * from tid_info ";
conn.Open();
DB2DataAdapter da = new DB2DataAdapter(sql,conn);
da.Fill(dt);
this.DataGrid1.DataSource=dt;
this.DataGrid1.DataBind();
在conn.Open() 出现异常
