Description

Sets the cache properties for the object cache, the page cache, or both. If a cache does not yet exist, creates it. The cache and properties are application-specific.

Returns

Nothing

Function syntax

CacheSetProperties(propStruct, [region])

CacheSetProperties(propStruct, [region])

History

ColdFusion 10: Added the parameter region.

ColdFusion 9: Added the function.

Parameters

Parameter	Description
propsStruct	A structure specifying the cache properties plus identifying information
region	(Optional) The name of the cache region

The propsStruct structure can have any or all of the following fields:

Structure element	Default	Description
diskPersistent	False	A Boolean value specifying whether to persist caches stored on disk through JVM restarts.
diskStore		The disk store. The disk store provides a spooling facility that can be used for additional storage during cache operation. The disk store can also be used for cache persistence. If one or more caches requires a disk store, but there isn't any disk store configured, a default directory is used. To disable creation of a disk store path, comment out the diskStore element in ehcache.xml, located in <ColdFusion home>/cfusion/lib. <diskStore path="java.io.tmpdir"/>
eternal	False	A Boolean value specifying whether no timeout or idletime applies. A true value indicates that the object or page is cached without any timespan being specified.
maxElementsOnDisk	10000000	The maximum number of objects that can be stored on disk if overfllowtodisk is true.
maxEntriesLocalHeap		The maximum number of objects that can be cached in memory. If the number is exceeded and overflowtodisk is false, the new objects entered replace old elements using algorithm specified in the memoryevictionpolicy entry.
memoryEvictionPolicy	LRU	The algorithm used to evict old entries when the maximum limit is reached. The algorithms used are: LRU (Least Recently Used) LFU (Least Frequently Used)
objectType	Object	The type of cache: one of the following: template - Set properties for the page cache, which contains cached pages and page segments. object - Set properties for the object cache. all - Set properties for both cache types.
overflowToDisk	False	A Boolean value specifying whether when the maximum number of elements allowed in memory is reached, objects can be moved to disk, as determined by the memoryevictionpolicy value.
statistics	True	true indicates that statistics collection for Ehcache is enabled.
timeToIdleSeconds	86400	The idle time in seconds. Used if a cfcache tag does not specify an idleTime attribute.
timeToLiveSeconds	86400	The timeout time in seconds. Used if a cfcache tag does not specify a timespan attribute.

Note:

maxelementsinmemory property name is renamed to maxentrieslocalheap. The reason for this change is that Ehcache has deprecated maxelementsinmemory.

Example

myProps = StructNew();

myProps.diskStore = "/Users/user1";

myProps.diskPersistent = true

myProps.eternal = false

myProps.maxElementsInMemory = "5000";

myProps.maxElementsOnDisk = "100000";

myProps.memoryEvictionPolicy = "LRU";

myProps.objectType = "Object";

myProps.overflowToDisk = "true";

myProps.timeToIdleSeconds = "86400";

myProps.timeToLiveSecond = "86400";

myProps.maxEntriesLocalHeap="20";

// remove cache region

CacheRegionRemove("myCacheRegion_1")

// create a cache region with struct myProps

CacheRegionNew("myCacheRegion_1",myProps,true)

// set properties for the cache

CacheSetProperties(myProps,"myCacheRegion_1")

writeDump(cacheGetProperties("myCacheRegion_1"));

</cfscript>

<cfscript> myProps = StructNew(); myProps.diskStore = "/Users/user1"; myProps.diskPersistent = true myProps.eternal = false myProps.maxElementsInMemory = "5000"; myProps.maxElementsOnDisk = "100000"; myProps.memoryEvictionPolicy = "LRU"; myProps.objectType = "Object"; myProps.overflowToDisk = "true"; myProps.timeToIdleSeconds = "86400"; myProps.timeToLiveSecond = "86400"; myProps.maxEntriesLocalHeap="20"; // remove cache region CacheRegionRemove("myCacheRegion_1") // create a cache region with struct myProps CacheRegionNew("myCacheRegion_1",myProps,true) // set properties for the cache CacheSetProperties(myProps,"myCacheRegion_1") writeDump(cacheGetProperties("myCacheRegion_1")); </cfscript>

<cfscript>
 myProps = StructNew();
 myProps.diskStore = "/Users/user1";
 myProps.diskPersistent = true
 myProps.eternal = false
 myProps.maxElementsInMemory = "5000";
 myProps.maxElementsOnDisk = "100000";
