Book description

IBM® Db2® Mirror for i provides a new solution for continuous availability for an IBM i environment based on an active-active clustering design that uses a low-latency communication protocol for synchronous database replication.

With Db2 Mirror, IBM i customers can benefit from continuous application availability for both planned and unplanned outages. Db2 Mirror can help reduce or eliminate application downtime for regular maintenance operations such as program temporary fix (PTF) installations, operating system (OS) upgrades, or for planned server outages.

This IBM Redpaper publication provides a broad overview and understanding of this new solution by covering its architecture, positioning, planning, and implementation aspects.

It provides an introduction reference for a seller or technical specialist audience to become familiar with the new Db2 Mirror solution.
