2）通过配置文件配置网络服务名

# tnsnames.ora Network Configuration File: C:\app\denghuanyin\product\11.2.0\dbhome_1\network\admin\tnsnames.ora # Generated by Oracle configuration tools. ORACLR_CONNECTION_DATA =   (DESCRIPTION =     (ADDRESS_LIST =       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))     )     (CONNECT_DATA =       (SID = CLRExtProc)       (PRESENTATION = RO)     )   ) LISTENER_ORCL =   (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) WLFWM =   (DESCRIPTION =     (ADDRESS_LIST =       (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))     )     (CONNECT_DATA =       (SERVICE_NAME = orcl)     )   ) ORCL =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = orcl)     )   ) # tnsnames.ora Network Configuration File: C:\app\denghuanyin\product\11.2.0\dbhome_1\network\admin\tnsnames.ora # Generated by Oracle configuration tools.

3数据库的监听文件描述
