PLSQL远程连接ORACLE数据库配置文件

因为是在win7上面用的10G客户端连接局域网中的另一台电脑，中间因为权限问题，弄了三个小时，终于搞定。在此， 特意给自己提个醒：在win7系统下，一定要用 管理员权限去安装软件，不然有可能会报莫名其妙的错误。
需要新建两个文件，放在oracle客户端安装目录下面的network/ADMIN/下面。
配置文件如下：
tnsnames.ora，此文件中主要配置oracle连接信息。

# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.251)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

listener.ora，此文件中主要配置oracle监听信息。

# listener.ora Network Configuration File: D:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\oracle\product\10.2.0\client_1)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = Win7-PC)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )
