我想运行DMS任务以将数据从本地Oracle DB复制到AWS上的Mysql。 我已经具有防火墙访问权限，并且能够从AWS ec2实例远程登录到oracle DB服务器。另外，我可以使用来自SQL开发人员的相同用户名/密码和连接字符串登录数据库 但是，当我在DMS上测试端点时，它将失败并显示以下错误。
仅供参考，DMS实例属于我获得防火墙许可的同一VPC。
Test Endpoint failed: Application-Status: 1020912, Application-Message: ORA-12545:

我在网络和数据库端都进行了检查，似乎没有问题。请提出建议。
答案 0 :(得分：0)
另一次我遇到类似的问题，我假设使用相同的VPC创建DMS和Oracle实例将保证它们之间的连接。我还假定为DMS和Oracle实例之间的开放端口添加入口规则也行得通，但是它们之间的连接失败了，我发现了两种方法：
首先：创建一个没有公共IP地址的DMS实例，目标连接将通过验证。它是第一次工作
第二：通过打开允许所有IP地址的条目，实例之间的连接将成功。
好看！
