TDP的ODP.NET问题，32位客户端64位数据库

Question

我的问题如下：

我在32位ubuntu服务器12.04 LTS中有一个Oracle，但是我创建了另一个用于迁移到Windows 2008 R2 64位的数据库。我成功安装了oracle并复制了我拥有的所有数据。当我不得不将我的一个.NET项目的连接从第一个连接更改为第二个连接时出现问题，我得到了“ORA-12154：TNS：无法解析指定的连接标识符”错误。我使用从Oracle下载的32位ODAC dll。

TNSNAMES：

A_LINUX =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.y)(PORT = 1523))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl2)
    )
  )

B_LINUX =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.y)(PORT = 1523))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl2)
    )
  )

C_LINUX =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.y)(PORT = 1523))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl2)
    )
  )

D_DBLILLY =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.y)(PORT = 1523))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl2)
    )
  )

E_DBLILLY =
  (DESCRIPTION =

    )
  )

    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl2)
    )
  )

A_WINDOWS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.z)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.c.local)
    )
  )

B_WINDOWS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.z)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.c.local)
    )
  )

C_WINDOWS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.z)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.c.local)
    )
  )

D_WINDOWS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.z)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.c.local)
    )
  )

E_WINDOWS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.z)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.c.local)
    )
  )

TEST_WINDOWS =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.x.z)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.c.local)
    )
  )

_WINDOWS是Windows的一个和Linux的_LINUX。有了这个tnsnames，我只能连接到linux。 ips是正确的，端口和名称也是如此。 ODAC安装在C：\ OracleODAC \ x32中，我将目录添加到PATH中。我也添加了bin目录。此外，正确设置了ORACLE_HOME和ORACLE_SID。

有提示吗？提前致谢。

编辑：我可以使用同一家庭与TOAD连接。我可以将我的项目连接到LINUX，但不能连接到WINDOWS，使用x86 / x64编译版本。

Answer 1

我先在databas-adm-program中测试oracle客户端。我使用Toad，我配置为使用与我的.net应用程序相同的oracle客户端。如果它在那里工作，你可以排除TNS是问题，只关注你的.net应用程序中的32对64位问题。 PS：我知道这适合作为评论，但我不能评论因为我在这里是一个n00b

Answer 2

看起来你对我有简单的TNS分辨率错误。您可能有多个oracle家庭并且没有意识到它，因此您缺少第二个tns名称文件。 IMO是强制tns名称文件的最简单方法是使用TNS_ADMIN环境变量。您还可以直接在连接字符串中嵌入TNS字符串代替别名。如果您使用的是托管客户端，则可以在配置文件本身中定义tns别名。所有这些都在另一个答案中得到了证明：

Answer 3

由于数据库是64位，我认为ODAC也应该是64位。看看这个页面得到好的：[http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html]

然后，我想一个听众正确启动???

在您的tnsnames中，您可能必须为连接标识符添加后缀：TEST_ASTREA.cartif.local =（DESCRIPTION =（ADDRESS =（PROTOCOL = TCP）（HOST = 192.168.109.103）（PORT = 1521））（CONNECT_DATA =（SERVER = DEDICATED）（SERVICE_NAME = orcl.cartif.local）））

希望有帮助......
