【问题描述】：

我正在努力使用 oracle forms 11g 连接到数据库。我将我的机器用作使用 weblogic 和 XE 数据库的本地主机。当我尝试使用 oracle 表单连接到数据库时，弹出此错误

“错误 ORA-12170: TNS: 发生连接超时”

这里是文件 C:\oracle\app\oracle\product\11.2.0\server\network\ADMIN

听众

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    )
  )
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = NB**MyIP**.com)(PORT = 1521))
    )
  )
DEFAULT_SERVICE_LISTENER = (XE)

sqlnet

# 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)

tnsnames

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = NB**MyIP**.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

我也变了

HOST = NB**MyIP**.com)(PORT = 1521)) to
HOST = localhost)(PORT = 1521))

并将所有文件复制到 C:\Oracle\Middleware10_3\asinst_1

并将 tnsnames 复制到
C:\Oracle\Middleware10_3\asinst_1\config

我有另一个用于 JDeveloper 的 C:\Oracle\Middleware\Oracle_Home。

我没有解决它的技术经验。

【问题讨论】：

您可以使用 SQLPlus 进行连接吗？你检查 sqlnet.log 了吗？
是的，我正在使用（SQL 命令行）连接并且它连接了。
我没有 sql*plus
我刚发现 sqlplus 在我连接时告诉我“ORA-12560: TNS:protocol adapter error” 我检查了服务并全部运行

标签： forms oracle ora-12170

【解决方案1】：

尝试更改 sqlnet.ora

添加：NAMES.DIRECTORY_PATH=(TNSNAMES)

并注释掉：#SQLNET.AUTHENTICATION_SERVICES = (NTS)

复制sqlnet.ora到asinst_1/config目录

【解决方案2】：

如果您的 oracle 数据库安装在 Windows 服务器上，请检查您的 Windows 服务器防火墙设置，确保关闭 Windows 内部防火墙
