Exadata Cloud@Customer: Enhanced Control to Rollback or Retry Failed Guest VM Operating System Update

You need not mandatorily roll back if applying the Guest VM operating system update fails. A new option, in addition to the current rollback option, has been added to retry and apply the failed update. If you want to apply a different operating system image update on failure, then you will have to first roll back and then apply.
