This document explains/answers persistence related how to questions? Usually customers are concern on functionality that does disk IO.Coherence persistence is a set of tools and technologies that manage the persistence and recovery of Coherence distributed caches. Cached data is persisted so that it can be quickly recovered after a catastrophic failure or after a cluster restart due to planned maintenance. Persistence and federated caching can be used together as required. Persistence uses a database (Oracle Berkeley DB Java Edition) for the persistence store. The database is used to store the backing map partitions of a partitioned service. The locations of the database files can be stored on the local disk of each cache server or on a shared disk on a storage area network (SAN).
