oracle12cPDB里建立的用户登录不上去，显示IO错误:Unknownhostspecified

连接失败, 错误报告:

user = store

url = jdbc:oracle:thin:@orclpdb

错误消息 = io 错误: unknown host specified

碰到这个问题的童靴们，正解如下：

首先在 oracle enterprise manager database express 12c中查看容器名是

然后在 $home$\product\12.2.0\dbhome_1\network\admin\tnsnames.ora中增加

orclpdb =

(description =

(address = (protocol = tcp)(host = localhost)(port = 1521))

(connect_data =

(server = dedicated)

(service_name = orclpdb)

)

)

这样，在登录的时候写@orclpdb就可以解析为本地host了，之前出现登录不了也就是无法解析到本地localhost
