尝试使用 eclipse 连接到 Oracle 12c 数据库时出错

Question

我正在尝试使用 Eclipse IDE 连接到 oracle 12c 数据库，但出现错误“Ping 失败！”每次我尝试测试连接时。我试图禁用 Windows 防火墙，因为其他一些类似的帖子暗示它可能与网络相关或防火墙阻止它。我有以下设置：
SID：XE
主机：本地主机
端口号：1521
用户名：我的用户名
密码：我的密码
连接地址：jdbc:oracle:thin:@localhost:1521:XE

对我做错了什么有任何想法吗？

Answer 1

将您的连接网址更改为jdbc:oracle:thin:@server:1521:db。这将起作用。
