ERROR ORA-12170: TNS:Connect timeout occurred (oracle forms 11g)

Question

I'm struggling to connect to the database using oracle forms 11g. I'm using my machine as a local host using weblogic and XE database. When I try to connect to the database using oracle forms, this error pops

"ERROR ORA-12170: TNS:Connect timeout occurred"

Here are the files C:\\oraclexe\\app\\oracle\\product\\11.2.0\\server\\network\\ADMIN

listener

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)
    )
  )

I also changed

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

and copied all files to C:\\Oracle\\Middleware10_3\\asinst_1

and copied tnsnames to
C:\\Oracle\\Middleware10_3\\asinst_1\\config

I have another C:\\Oracle\\Middleware\\Oracle_Home for JDeveloper.

I don't have technical experience to solve it.

Answer 1

try changing sqlnet.ora

add: NAMES.DIRECTORY_PATH=(TNSNAMES)

and comment out: #SQLNET.AUTHENTICATION_SERVICES = (NTS)

copy sqlnet.ora to the asinst_1/config directory

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