Configuring Caches via Settings Framework​

The settings framework can configure several caches. Each cache has three settings:

  • timeToIdle: Sets the time to idle for an element before it expires in seconds

  • timeToLive: Sets the time to live for an element before it expires in seconds

  • maxEntriesLocalHeap

For example, to change the timeToIdle and timeToLive values for categoryByUidCache and childCategoryLookupCache to 5 minutes, change the values of the COMMERCE/SYSTEM/CACHING/CATEGORY/timeToLive and COMMERCE/SYSTEM/CACHING/CATEGORY/timeToIdle settings to 300. Note that the changes will not take effect until the application is restarted. For details on how to change these system settings, see Configuring System Settings.

Configuring Caches via Ehcache​

All caches can be configured using Ehcache configuration files as described in Configuring Ehcache. This will override any compile-time or settings framework configuration.

OpenJPA Data Caching​

OpenJPA supports caching transactional persistent entities (anything submitted or updated regularly as an online transaction such as orders, payments and customers). By default, all relatively static objects, including catalog entities, are cached unless the following annotation is specified in the source code of the persistent entity class:

@DataCache(enabled = false)

OpenJPA is configured to use Ehcache for its data and query caches, as specified by jpa-persistence.xml in ep-core.

The OpenJPA L2 cache timeout defaults to one second so that data changes are immediately visible in development, QA, and staging environments. For live environments, cache timeouts can be increased to optimize performance using an external configuration file. See Configuring Ehcache for details.

For more information on configuring OpenJPA’s properties, see the OpenJPA User’s Guide.

Override Persistence Unit Properties​

Occasionally you may wish to override some of the properties defined in the core persistence unit, or add new properties. To do so, add the properties to the persistencePropertyOverrides map in the core extension’s ep-core-plugin.xml file. Do not add or change properties in any of the jpa-persistence.xml files, as the order in which these files are resolved cannot be guaranteed.
