DB2 - HADR Performance Tuning and Diagnostics

When the DB2 HADR feature is enabled, the primary database's transaction logs are replicated to one or more standby databases in real time. The replication provides HA and DR protection, at a cost. The replication adds overhead to the primary's log writing. Applications on the primary may exprience slow down. This article will focus on HADR performance specifically.

- Configuring HADR for Optimal Performance: Preventive Care
- Monitoring HADR Performance: Get early warning of problems
- Diagnosing and fixing HADR performance problems: When a problem does occur, how to fix it.
