The PersistenceManagerMBean MBean includes a set of notification types that applications can use to monitor persistence operations. Subscribing to Persistence JMX Notifications.Suitability is based on availability of all partitions and sufficient capacity to initiate recovery across storage members. You can choose to define and use multiple persistence environments to support different cache scenarios.Ĭoherence includes a quorum policy that enables Coherence to defer recovery until a suitable point. You can choose to use the default storage directories or change the directories as required. Persistence uses a set of directories for storage. Modifying the Pre-Defined Persistence Environments.You can enable and configure active persistence mode to have the contents of a cache automatically persisted and recovered. Archiving snapshots requires defining the directory where archives are stored and configuring cache services to use an archive directory. Snapshots can be archived to a central location and then later retrieved and restored. Snapshots are a backup of the contents of a cache service that must be manually managed using the PersistenceManagerMBean MBean.
Using Snapshots to Persist a Cache Service.Persistence is only available for distributed caches and requires the use of a centralized partition assignment strategy.Ĭaches can be persisted to disk at any point in time and recovered as required.Ĭaches can be automatically persisted to disk and automatically recovered when a cluster is restarted. Coherence persistence is a set of tools and technologies that manage the persistence and recovery of Coherence distributed caches.
