Amazon RDS是否支持每个实例部署多个Oracle数据库？

Hey there, let's break this down clearly:

No, Amazon RDS for Oracle does not support deploying multiple distinct standalone databases on a single instance.

As stated in AWS's official FAQ:

For Oracle on Amazon RDS, you can only create one database per instance.

If you need multiple Oracle database environments, here are two common approaches used by developers and DBAs:

• Provision separate Amazon RDS Oracle instances for each database. This ensures full isolation between each environment and adheres to RDS's constraints for Oracle.
• If you're using Oracle Database 12c or later (specifically Enterprise Edition), you can leverage Pluggable Databases (PDBs) within a single Container Database (CDB) on RDS. While this isn't identical to having fully independent standalone databases, it lets you manage multiple self-contained database environments under one CDB, which can be a cost-effective alternative for some use cases.
