CDD Backing Store
To provide for data persistence, you can implement a backing store for use with Cache OM.
During regular operation, cache data is written to the backing store. On system restart, data in the backing store is restored to the cache cluster.
To implement a backing store, provide a supported database product. Scripts are provided to set up the database for your project’s ontology. If the ontology changes, scripts help you adapt the backing store accordingly and existing backing store data can be preserved.
Oracle Database Strategy
If the Strategy field for an Oracle database with a Shared All persistence (set under the Cluster tab > Backing Store) is set to oracle, then Oracle Database pooling strategy settings are used and various CDD properties act on the corresponding Oracle property, as noted in the reference table.
- Configuring Backing Store Settings and Properties
The Cluster tab is used to configure the backing store settings and properties. - Setting Up Shared Nothing Persistence
Shared Nothing persistence allows you to store data at individual node level, instead of a centralized location. - Recovery Options for Shared Nothing Persistence
You can use five policies for the shared nothing persistence as recovery options.
