远程连接Oracle数据库
网上搜了很多方法，这个可行！
1、 配置服务器tnsnames.ora文件，如果本机上没有安装oracle，可以从安装了oracle的机上拷贝一个(tnsnames.ora文件)放在指定目录下，因为我已安装oracle，所以直接配置该文件。
# tnsnames.ora Network Configuration File: D:\Oracle11g\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORACLR_CONNECTION_DATA =

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

)
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.25.224)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
