Object Storage Bucket Creation and OIC Connection

Abstract

This blog presents a step-by-step approach to establishing a secure and functional integration between Oracle Integration Cloud (OIC) and Oracle Cloud Infrastructure (OCI) Object Storage. It outlines the prerequisites and detailed configuration steps required to enable OIC to interact with Object Storage for various integration use cases, such as file-based data exchange, archiving, and payload management.

The process includes the creation of an Object Storage bucket, setting up a service account and IAM group, defining access policies, and finally, configuring the Object Storage connection within OIC. By following this guide, users can ensure proper access control, security compliance, and operational efficiency when handling files through Oracle's integration platform.

This blog is particularly useful for cloud integration practitioners and enterprise IT teams seeking to enable OIC-to-Object Storage connectivity in a controlled and scalable manner.

 

Introduction

This blog provides a comprehensive guide to integrating Oracle Integration Cloud (OIC) with Oracle Cloud Infrastructure (OCI) Object Storage. It outlines the detailed steps required to set up and configure the necessary cloud components to enable secure and seamless connectivity between OIC and Object Storage.

The blog is intended for integration architects, developers, and cloud administrators who are responsible for designing and implementing integration solutions using Oracle's cloud services. Whether the goal is to store files, retrieve data, or enable file-based integrations, this guide ensures that all foundational elements are correctly configured.

Key setup steps covered in this blog include:

• Creating an Object Storage bucket to serve as the data repository.
• Creating a Service Account with appropriate privileges for OIC interactions.
• Defining a Group and assigning the service account to it.
• Adding IAM policies to grant the necessary access rights to Object Storage.
• Configuring the Object Storage connection in OIC using service principal authentication.

By following this step-by-step guide, organizations can ensure a secure, scalable, and efficient setup for leveraging Object Storage within their OIC integrations.

Object Storage Bucket Creation

Login to OCI Console.

Navigate to Storage -> Buckets under Object Storage & Archive Storage

Select the Compartment that you want to create a bucket in.

Click on the Create Bucket button and provide the details as shown below.

 

Once all the details are completed click on the Create button.

The bucket will be created.

 

Create Service Account User for Object Storage

Navigate to Identity & Security -> Domains under Identity

Select the compartment.

Then click on the users count of the domain of your interest.

Click on Create.

Provide the details of the service account user to be created.

Click on Create button and the user will be created.

Create Group and assign the service account user created

Now Navigate to Groups by Clicking on the count of groups.

Click on the Create Group button.

Click on Create after filling in the Name and Description.

Goto Users tab in the group and click on Assign user to group.

Search for the service account user you need to add to the group and Click on Add button.

 Adding API Key to the Service Account User

Now select the user for which you need to create the API Key

Click on Add API key.

Download the Private Key and Public Key and click Add button.

You will see the window below, click close.

You will now see the fingerprint for the API Key generated. Make a note of this, it will be used in the OIC Connection.

Convert the PGP Private Key

On your local machine where the key is downloaded, open command prompt and navigate to the folder where the key is present.

Run the below command to convert the public key to RSA.

ssh-keygen -p -f svc-dev-oic-objs-hcm-2025-07-14T12_58_18.669Z.pem -N "Welcome123" -t rsa -m pem

This is done. This key will be used in OIC Connection.

Add the Policy for Object Storage Bucket

Navigate to Identity & Security -> Select Policies under Identity.

Select the compartment where the bucket is created.

Click Create Policy button to add the Policy.

Provide the Name, Description.

In Policy Builder section click on Show manual editor.

Add the below policy statements.

Allow group fa-ibavqqwey-dev1-blq7t/oci_ocs_streaming_admin to manage buckets in compartment DEV-Storage

Allow group fa-ibavqqwey-dev1-blq7t/oci_ocs_streaming_admin to manage objects in compartment DEV-Storage

Click Create

Object Storage Bucket OIC Connection

Login to OIC and Navigate to Connections under Design.

Click Create and search for REST Adapter.

Provide the Name, Description and Role (Trigger and Invoke). Click on Create.

Now provide the details for Properties and Security sections.

You can get the Tenancy OCID from OCI.

 To get Tenancy OCID -> click on the top right corner on the profile icon.

Click on the Tenancy name, you will see the Tenancy information and copy OCID.

 To get User OCID -> click on the top right corner on the profile icon.

Click on the User name, you will see the User information and copy OCID.

Now upload the pgp private key which we converted to RSA format in earlier step.

Enter the Fingerprint and under optional security enter Pass Phrase.

Click on Test and then Save.

Conclusion

Establishing a reliable and secure connection between Oracle Integration Cloud (OIC) and Oracle Cloud Infrastructure (OCI) Object Storage is a foundational step for enabling file-based integrations and data exchange scenarios in the cloud. This blog has detailed the end-to-end process, including the creation of the Object Storage bucket, setting up a service account and IAM group, assigning the necessary policies, and configuring the OIC connection.

By following these steps, organizations can ensure that their integration flows can safely store, retrieve, and manage files within OCI Object Storage while adhering to best practices in identity and access management. This setup not only supports current integration needs but also lays the groundwork for scalable and secure expansion of cloud-native workflows in the future.

Implementing this integration framework empowers enterprises to streamline operations, maintain compliance, and fully leverage the capabilities of Oracle’s cloud ecosystem.
