远程连接Oracle数据库设置

1、设置listener.ora

首先找到自己电脑上的listener.ora文件，以下是我自己的地址：D:\app\UZ\product\11.2.0\dbhome_1\NETWORK\ADMIN

将HOST=localhost改HOST = 主机名，因为使用localhost不能进行远程访问。主机名可在我的电脑里查询到

listener.ora

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

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = UZ-PC)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\app\UZ

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

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = UZ-PC)(PORT = 1521))
)
)

ADR_BASE_LISTENER = D:\app\UZ

2、然后设置tnsnames.ora

同样也是在这个文件夹下：D:\app\UZ\product\11.2.0\dbhome_1\NETWORK\ADMIN

①将HOST=localhost改为HOST = UZ-PC

②将ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = UZ-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

复制一份做一些简单的改动：

zhangqian =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.15.109)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

tnsnames.ora

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

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = UZ-PC)(PORT = 1521))

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

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = UZ-PC)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

zhangqian =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.15.109)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

两个配置文件改动之后就可以访问10.1.15.109下的Oracle数据库了：
