Topic: DB2 for LUW
This presentation covers DB2 pureScale geographically dispersed clusters. pureScale is DB2 LUW’s answer to DataSharing in DB2 z/OS to provide DB2 LUW with unlimited scalability and high availability. Until now, pureScale clusters have only been supported in configurations where the physical boxes were placed within a very limited distance of one another. By exploiting some very advanced network technology, pureScale clusters can now be 'stretched' so that they can be used in an installation where 2 sites are placed kilometers apart. In this way pureScale can take part in an "active/active" disaster recovery (DR) setup, where one surviving site can take over the workload should the other site fail, and in this way ensure maximum availability. In 2011 Bankdata/JN Data and IBM started a ‘Proof of Concept’ to bring this setup into the Bankdata/JN Data installation. This presentation will be covering both the physical (hardware) setup, the software setup and information about all the tests of the error scenarios that were performed at Bankdata/JN Data to verify the solution.
