注意：我本地安裝oracle11gR2 64位，桌面類；

• 我本地安裝目錄：D:\app\ELONG\

解決辦法：

1. 修改D:\app\ELONG\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora，修改host=為你本機的IP地址，遠端通過IP訪問；

• 修改前listener.ora,如下:

# listener.ora Network Configuration File: D:\app\ELONG\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 = D:\app
 
\ELONG\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\ELONG\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    ) 
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app
 
\ELONG

• 修改後listener.ora

# listener.ora Network Configuration File: D:\app\ELONG\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 = D:\app\ELONG\product
 
\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\ELONG\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    ) 
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.27.135)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app\ELONG

2. 修改D:\app\ELONG\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora，修改host=為你本機的IP地址，遠端通過IP訪問；

• 修改tnsnames.ora前：

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

SYDJ =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = SYDJ)
    )
  )

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

LISTENER_SYDJ =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))

• 修改tnsnames.ora後：

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

SYDJ =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = SYDJ)
    )
  )

SYDJ2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.27.135)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = SYDJ)
    )
  )

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

LISTENER_SYDJ =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
LISTENER_SYDJ2=
  (ADDRESs = (PROTOCOL = TCP)(HOST=192.168.27.135)(PORT=1521))

結果：

• 現在可以通過遠端連線到192.168.27.135這臺oracle資料庫；
