DB2 10.1 HADR Multiple Standbys

The multiple standby HADR feature provides database administrators (DBAs) with a single technology to provide both high availability (HA) as well as disaster recovery (DR). This paper shows how HADR multiple standbys can be set up, configured, and monitored. In addition, various examples demonstrate how HADR multiple standby behaves in different failure scenarios.
