Modifications to ehcache.xml in ColdFusion 9.0.1
ehCache.xml includes the following configuration properties:
•

Use secondary cache
To use secondary cache, you must configure the following settings in the application:
•
ormsettings.secondarycacheenabled
This setting defines whether the secondary cache would be used by the application. By default, this is set to false.
•
ormsettings.Cacheprovider
This setting defines the cache provider that needs to be used for secondary cache. This defaults to EHCache. The
other values for this setting are JBossCache, OSCache, SwarmCache and Hashtable. You can also specify the fully
qualified class name of the cache provider.
•
ormsettings.cacheconfig
This setting defines the configuration file required by the secondary cache provider. For example, EHCache
requires that defines the configuration settings for the secondary cache. Specify the path to the XML
EHCache.xml
file in this setting. If this setting is not defined, cache provider uses its default configuration.
