Can co-exists S3 and EFS integration on RDS Oracle?

Yes, it is possible to coexist S3 and EFS (Elastic File System) integration on an Amazon RDS Oracle. These two integrations serve different purposes and can be used concurrently to meet various data storage and retrieval needs.

Here's a brief explanation of each integration and how they can coexist:

S3 Integration: Amazon RDS provides S3 integration, allowing you to export data from your RDS instance to Amazon S3 buckets and import data from S3 to your RDS instance. This integration is typically used for backup, data transfer, and data export purposes. It's a convenient way to store and retrieve large amounts of data for archival or analytical purposes.

EFS Integration: Elastic File System (EFS) integration is a feature that enables you to connect your RDS instance to an EFS file system. EFS is a scalable and shared file storage system that can be mounted to multiple instances. This integration can be useful if your application needs a shared file system for read and write operations across multiple instances.

These two integrations do not conflict with each other, and you should be able to configure and use both simultaneously if your application requires both functionalities. Make sure you configure them properly, and ensure that the security and access controls are set up correctly to protect your data.

If you encountered an error while attempting to add the EFS integration to your RDS instance and it was resolved by removing the EFS option, it might have been due to a specific configuration issue or resource limitations at the time. You can try adding the EFS integration again and ensure that your RDS instance meets the requirements for both integrations.
