错误ORA-12170: TNS:发生连接超时(甲骨文表格11g)

Question

我很难用oracle 11g连接到数据库。我使用我的机器作为本地主机使用weblogic和XE数据库。当我试图使用oracle窗体连接到数据库时，此错误将弹出。

错误ORA-12170: TNS:连接超时发生

以下是C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN文件

侦听器

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)

tnsname

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

并把名字拷贝到

C:\Oracle\Middleware10_3\asinst_1\config

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

我没有解决这个问题的技术经验。

Answer 1

试着改变sqlnet.ora

添加: NAMES.DIRECTORY_PATH=(TNSNAMES)

评论：#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，请检查windows服务器防火墙设置，确保关闭windows内部防火墙
