Question

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

＆＃34; ERROR ORA-12170：TNS：发生了连接超时＆＃34;

以下是文件 C：\ oraclexe \应用\ ORACLE \产品\ 11.2.0 \服务器\网络\ ADMIN

听者

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)
    )
  )

我也改变了

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：\甲骨文\ Middleware10_3 \ asinst_1 \配置

我有另一个C：\ Oracle \ Middleware \ Oracle_Home for JDeveloper。

我没有技术经验来解决它。

Answer 1

尝试更改sqlnet.ora

添加：NAMES.DIRECTORY_PATH =（TNSNAMES）

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

将sqlnet.ora复制到asinst_1 / config目录

Answer 2

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