In this blog, I'll demonstrate the steps to create a custom database software image using OCI console then use the new image to create a database home.

Step #1: Create A  Custom Database Software Image

1.  Sign in to your OCI tenancy where your Exadata Database Service on Cloud @ Customer system is deployed.

2. Navigate to "Oracle Database" > "Oracle Exadata Database Service on Cloud@Customer".
