Ability to move application spaces between two separate independent high availability (HA) environments

Abstract:

In embodiments, the ability to have two separate Db2 Mirror pair environments, each providing HA, which have the capability to switch application spaces between the Db2 Mirror pairs, is presented. At least one IASP is registered to a first node of a first pair of nodes at a first HA mirroring environment at a first location. The at least one IASP is replicated to a second HA mirroring environment, the second HA mirroring environment including a second pair of nodes at a second location, the second location different than the first location. The at least one IASP is registered with one node of the pair of nodes of the second mirroring environment, the at least one IASP is switched offline at the first pair of nodes of the first mirroring environment, and subsequently switched online at the second pair of nodes of the second mirroring environment.
