概述
我参考本教程https://docs.aws.amazon.com/dms/latest/sbs/CHAP_RDSOracle2Redshift.html学习将 Amazon RDS for Oracle Database 迁移到 Amazon Redshift
麻烦
我在下面的问题上遇到了麻烦。 我想使用 AWS SCT 将 Oralce DB 迁移到 Amazon Redshift
在人们的帮助下，我设法摆脱了困境。然而，我遇到了新的麻烦。我尝试使用 AWS SCT 连接到 Amazon Redshift。AWS Redshift 无法连接。 图片
我看到了日志文件。日志中记录了一个错误。

我尝试什么
[Amazon](500150) Error setting/closing connection: Connection timed out: connect.
我认为上述错误与问题相似。因此，我启动了安全组控制台并添加了 [Rule: Type=Redshift, Source=MyIP]。
我保存了它并尝试再次连接。不幸的是，AWS Redshift 无法连接并出现同样的错误。我不知道下次要做什么。我该做什么？
