People ask what do I look for when monitoring an EBS instance for availability? Oracle Enterprise Manager (OEM) with the Applications Management Pack (AMS) gives a good starting point, but here is a condensed list of my general health check items for my production instance. It’s not everything possible, but it’s what I generally would check during a shake-down of a disaster-recovery exercise.
