—-Building Private Images
Keep your image disk size just as small as is essential. A large image requires more time to be uploaded to Oracle Storage Cloud Service, and costs more to store. In addition, creating instances and bootable storage volumes from a large image requires more time. Before uploading image files to Oracle Storage Cloud Service, make them sparse files. On Linux, you can convert a file to the sparse format by running the command, cp –sparse=always original_file sparse_file. And when creating the tar archive, to ensure that the tar utility stores the sparse file appropriately, specify the -S option.

Updating a Private Machine Image
After you’ve registered a private machine image in Oracle Compute Cloud Service, if required, you can update the description of the machine image.

To complete this task, you must have the Compute_Operations role. If this role isn’t assigned to you or you’re not sure, then ask your system administrator to ensure that the role is assigned to you in Oracle Cloud My Services. See Modifying User Roles in Managing and Monitoring Oracle Cloud.

Sign in to the Oracle Compute Cloud Service console. If your domain spans multiple sites, select the appropriate site. To change the site, click the Site menu near the top of the page.
Click the Images tab.
The Private Images page is displayed.
Go to the image that you want to update, and from the menu icon menu, select Update.
In the Update Image dialog box, edit the description of the image. Enter a meaningful description that will help you to identify the image and its attributes easily. Click Update.
