Description of the illustration fig5-confdistributedfail.gif

The image shows four boxes that each represent a JVM in a Coherence cluster. Each JVM contains and application box and a DistributedCache Map box. Each DistributedCache Map box contains three boxes: a logical cache box, a primary storage box, and a backup box. An X is placed over JVM 2 to indicate that the JVM has failed and its data is no longer available. The application in JVM one is performing four get operations for data that is labeled A though D. The get operation is performed using the data from the logical cache of JVM one. However, the data is being retrieved from the other JVMs as follows: data A is being retrieved from primary storage on JVM one and is also shown on JVM four backup storage; data B is being retrieved from primary storage on JVM three and is also shown on JVM four backup storage; data C is being retrieved from primary storage on JVM three and is also shown on JVM one backup storage; and data D is being retrieved from primary storage on JVM four and is also shown on JVM three backup storage. The image shows that primary data and backup data for JVM two was relocated to different JVMs.
