Oracle 客户端配置监听(TNSNames.ora设置)
① 只需在文件 TNSNames.ora 中加入以下节点，即可成功配置监听
ORCL190 = //红色部门为连接监听名字
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.190)(PORT = 1521)) //红色部门为服务器所在IP地址 1521为端口号
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl) //红色部门为数据库名
)
)
② 用DOS 连接Oracle数据库,看看是否能连上数据库
>CMD
>sqlplus 用户名/密码@接监听名字
