Inside The OpenEdge RDBMS: After-Image Log Records And Their Uses

The OpenEdge RDBMS uses two different kinds of transaction logs. These form the basis for a variety of important features like transaction rollback, crash recovery, replication, media failure recovery and so on.

In this talk we will open the bonnet on the topic of After-Image Journaling and Recovery Log Records (aka “Notes”).  We will describe what they are, what they do, and how to monitor them. But most importantly, we will show you some practical applications and uses of your newfound understanding of Notes.
