Question

This is the code that I use to connect with the Oracle database that is on my pc:

Class.forName("oracle.jdbc.driver.OracleDriver");
Connection co = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:etecsa", "system", "asd");

It works but if I change localhost for an ip it can not connect to the database. I already deactivated the firewall but nothing.

Class.forName("oracle.jdbc.driver.OracleDriver");
Connection co = DriverManager.getConnection("jdbc:oracle:thin:10.8.6.50:1521:etecsa", "system", "asd");

Where can I configure the oracle database to accept the connection from a specific ip and not only from localhost?

检查documentation for DB URL

JDBC：预言：driver_type：[用户名/密码] @database_specifier

所以在你的情况下（如果 etecsa 是SID），网址将为@host:port:SID

jdbc:oracle:thin:@10.8.6.50:1521:etecsa

如果 etecsa 是服务名称，请使用@//host:port/service_name

jdbc:oracle:thin:@//10.8.6.50:1521/etecsa
