Backup Cluster - Scenario and configuration description

The major steps to configure backup clusters are adding the backup cluster settings and optionally creating a core group bridge. Items to configure are:

  1. WebSphere cell and cluster setup.

  2. Security considerations. We need to import or export LTPA keys to handle security across cells.

  3. Backup cluster configuration.

  4. Core group bridge configuration (optional).

We use the IBM Trade Performance Benchmark Sample for WAS (called Trade 6 throughout this book) as the sample application in our backup cluster configuration.
