Practical SQL: Accessing Journals with SQL

Journals and SQL are two of the most powerful features of DB2 for the IBM i; together they create an incredible tool to help manage your data access.

By Joe Pluta

As IBM midrange programmers, we’ve long been familiar with journaling. It’s the way the IBM i tracks changes to the database. Journals can be used to recover or reverse changes. Journaling is the basis of commitment control for DB2. Journaling is the underpinning for many high-availability replication tools, both commercial and home-brewed. But to me, the best feature of journaling is the ability to see when a database gets changed. It’s invaluable for forensic application debugging, something I do on a regular basis. And while the built-in support for journaling on the IBM i is functional, it isn’t all that user-friendly. This article will show you how to make it a lot more accessible through SQL.
