Oracle SQL Developer(版本1.5.5)连接问题, Oracle11g(版本11.2)

配置软件安装目录下D:\app\Administrator\product\11.2.0\dbhome_2\NETWORK\ADMIN的tnsnames.ora文件:

修改当前环境下的主机名/端口和服务名;

如:

# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_2\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

LISTENER_ORCL =

(ADDRESS = (PROTOCOL = TCP)(HOST = WIN-COSDJDSFC4C)(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 = WIN-COSDJDSFC4C)(PORT =1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = ORCL) #注意这里的ORCL是服务名, Net Manager中的服务命名; 而不是windows后台服务名.

)

)

以上是我本机配置

建立连接:

使用scott账号密码tiger, 这个账号通过sysdba账号使用sqlplus解锁 ,设置界面如下:



注意: 经测试不能使用sysdba建立连接, 否则失败.
