Daekyo is using Oracle Linux OS 5.4.
When doing maintenance tasks, store the back up images of Oracle Fusion Middele Ware product through AMI and re-load the images through AKI.
But they are not able to re-load the back-up image through AKI since Daekyo got the guide from AWS as down below.
"It has come to our attention that you have been using one or more shared AMIs shared by another AWS customer on account #725966715235. This account was recently removed without warning or notice by the AWS customer. The customer in question has also permanently removed the S3 bucket containing the publicly shared snapshots for these AMIs and the Kernel images (AKIs) used to boot them. If you are negatively affected by this, we recommend that you continue to work with AWS Support to ensure that you have a clear understanding of your options for preserving your data. We recommend that you also contact your AWS account team to review your options for a fully supported solution, including the operating systems and database products of your choice."
Please give us a guide of this case.
