数据库是19c rac pdb环境,当前测试连其中一个vip地址,通过vpn后,sqlplus和pl/sql工具都可以连接到数据库,但是用oracle sql developer工具却报错,后来又尝试dbeaver也错,DbVisualizer也报错。太奇怪了。
通过DBeaver工具的时候发现连接走的是jdbc:oracle:thin
想起这些工具走的都是它,所以查询
通过搜索 jdbc:oracle:thin The Network Adapter could not establish the connection这个发现
找到配置文件下:
添加这个 AddVMOption -Djava.net.preferIPv4Stack=true 重启客户端工具,再连接成功。
相关:
DBeaver修改如下dbeaver.ini:
添加
-Djava.net.preferIPv4Stack=true
其它类似问题:
