Accelerating Oracle E-Business Suites upgrades

Taking backups during development, testing, or upgrades

The process of upgrading an Oracle E-Business Suites (EBS) system is one requiring dozens or hundreds of steps. Think of it like rock climbing. Each handhold or foothold is analogous to one of the steps in the upgrade.

What happens if you miss a handhold or foothold?

If you are close to the ground, then the fall isn’t dangerous. You dust yourself off, take a deep breath, and then you just start climbing again.

But what happens if you’re 25 or 35 feet off the ground? Or higher?

EC2 outage reactions showcase widespread ignorance regarding the cloud

Amazon EC2′s high-profile outage in the US East region has taught us a number of lessons.  For many, the take-away has been a realization that cloud-based systems (like conventionally-hosted systems) can fail.  Of course, we knew that, Amazon knew that, and serious companies who performed serious availability engineering before deploying to the cloud knew that. In cloud environments, as in conventionally-hosted environments, you must implement high-availability if you want high availability.  You can’t just expect it to magically be highly-available because it is “in the cloud.” Thorough and thoughtful high-availability engineering made it possible for EC2-based Netflix to experience no service interruptions through this event.
