[Building Sakai] Configuring SITE_PAGE_PROPERTY cache

[David Horwitz]

Hi All

I need urgent help configuring the SITE_PAGE_PROPERTY  cache. We're 
seeing very high disk IO and seeing that this cache seems to be heavily 
overflowing to disk. id like to:
- increase the in memory size
- disable overflow to disk.

I've tried editing the cache definition in db-components.xml:

<bean id="db.cache.SAKAI_SITE_PAGE_PROPERTY"
            class="org.springframework.cache.ehcache.EhCacheFactoryBean">
<property name="cacheManager" 
ref="org.sakaiproject.memory.api.MemoryService.cacheManager" />
<property name="cacheName" 
value="org.sakaiproject.db.BaseDbFlatStorage.SAKAI_SITE_PAGE_PROPERTY" />
<property name="maxElementsInMemory" value="30000" />
<property name="overflowToDisk" value="false" />
</bean>


But this does not seem to have any effect on the cache configuration. 
Any ideas?

For those interested a snapshot of why I want to make this change:

> [ name = 
> org.sakaiproject.db.BaseDbFlatStorage.SAKAI_SITE_PAGE_PROPERTY status 
> = STATUS_ALIVE eternal = false overflowToDisk = true 
> maxElementsInMemory = 10000 maxElementsOnDisk = 10000000 
> memoryStoreEvictionPolicy = LRU timeToLiveSeconds = 3600 
> timeToIdleSeconds = 3600 diskPersistent = false 
> diskExpiryThreadIntervalSeconds = 120 cacheEventListeners: hitCount = 
> 445958 memoryStoreHitCount = 316076 diskStoreHitCount = 129882 
> missCountNotFound = 187641 missCountExpired = 48741 ]

Thanks

David
