In this session, we will discuss journaling and its role in logical replication, hardware replication and also its benefit to availability when you not using any type of replication. You might think you don't need journaling if you are not replicating, not using commitment control, and not using other advanced DB2 Features, but that's not the case. We will answer questions such as:
What is journaling doing at its core?
What are the benefits for journaling when I'm not replicating to a second system?
Why do I need to journal for Hardware Replication?
Why should I journal if I want to use Flash Copy?
What is remote journaling and how is it used for Logical Replication?
What are the journaling implications for DB2 Mirror combined with long distance logical replication?
How can I improve journaling performance, disk consumption and remote journaling bandwidth?

Learning Objectives:
1. Understand the basic IBM i DB2 journaling technology's purpose
2. Understand why journaling is useful or required for several different use case scenarios.
3. Learn some basic journal performance tips.
