  • Coherent cloning of active compute nodes
    Patent number: 11194633
    Abstract: Techniques for warm cloning of computing nodes are provided. A request to clone a first computing node is received. Upon determining that a first transaction of a plurality of transactions is ongoing, a first moment in time when data associated with the first transaction was coherent on the first computing node is identified. Tracking data related to the first transaction is collected, beginning at the first moment in time. Further, a first storage associated with the first computing node is copied to a second storage associated with a second computing node, where the first transaction continues during the copying. The tracking data related to the first transaction is then transmitted to the second computing node.

  • Ability to move application spaces between two separate independent high availability (HA) environments
    Patent number: 11176166
    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.
