我已经在我的系统上设置了一个本地 Oracle 数据库，并且可以通过 SqlDeveloper 和 Sql*Plus (sqlplus system/mypassword@ORACLE) 进行连接，但是当我尝试在 Visual Studio 的部署选项中设置 ODP.Net 连接字符串时2010 CLR 项目然后我得到一个 ORA-12154：TNS：无法解析指定的连接标识符。

我执行的操作：Visual Studio 2010
文件

  • 新项目
  • 数据库
  • 甲骨文
  • Visual C# 甲骨文项目

建造

  • 部署
  • Oracle 部署向导启动，我创建一个具有以下细节的新连接：
  • 数据源：Oracle 数据库 (ODP.NET)
  • 数据源名称：ORACLE
  • 用户名：系统
  • 通行证：我的密码
  • 测试连接
  • ORA-12154: TNS: 无法解析指定的连接标识符

我的 tnsnames.ora 的内容：

# tnsnames.ora Network Configuration File:     c:\app\oracle\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORACLE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ORACLE)
    )
  )

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

我的listener.ora的内容：

# listener.ora Network Configuration File:     c:\app\oracle\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = c:\app\oracle\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS =     "EXTPROC_DLLS=ONLY:c:\app\oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = myhost.domain.com)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = c:\app\oracle

sqlnet.ora的内容：

# sqlnet.ora Network Configuration File:     c:\app\oracle\product\11.2.0\dbhome_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

# This file is actually generated by netca. But if customers choose to 
# install "Software Only", this file wont exist and without the native 
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

回答我自己的问题：通过在我的 listener.ora 中将 myhost.domain.com 替换为 localhost 解决了这个问题
