推荐答案

1.IP地址不正确-请尝试PING< ip>
2.端口未打开，或者被防火墙阻止-请尝试TELNET< ip>. < port>
3. DB侦听器未运行或绑定到其他网络接口-再次，TELNET应该确认这一点(也使用Oracle客户端工具进行连接)
4.没有本地端口可用于传出连接(不太可能)-仅当您正在建立数千个连接或每分钟创建数百个新连接时.

1.IP address is incorrect - try PING <ip>
2. The port is not open, or is blocked by a firewall - try TELNET <ip> <port>
3. The DB listener is not running or is binding to a different network interface - again, TELNET should confirm this (also use Oracle client tools to connect)
4. No local ports are available for the out-going connection (unlikely) - only if you''re making thousands of connections, or creating hundreds of new connections every minute.
