does this sound like your problem? https://issues.apache.org/jira/browse/JCS-32
-----Original Message----- From: Ron Zohar [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 13, 2008 3:49 AM To: jcs-users@jakarta.apache.org Subject: wrong key count in indexed key cache ?? Hello, I am currently evaluation JCS. I am adding 10.000.000 objects to the cache. On program exit and restart only approx 300.000 keys are written/read from the keys-file. Is this a bug or do I have to change something in the configuration ? I was expecting to use the disk cache as an (unreliable) object store, to be able to retrieve all objects after restart of the JVM. Further question: In case MaxPurgatorySize == 0, no objects are written to the disk cache. I was expecting that objects will be written immediately to disk. Concerning the file: what do you think of using a memory mapped file. would that be more efficient in case of large disk caches ? # DEFAULT CACHE REGION jcs.default=DC jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttribut es jcs.default.cacheattributes.MaxObjects=1000 jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory .lru.LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=false jcs.default.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.elementattributes=org.apache.jcs.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.MaxLifeSeconds=21600 jcs.default.elementattributes.IdleTime=1800 jcs.default.elementattributes.IsSpool=true jcs.default.elementattributes.IsRemote=true jcs.default.elementattributes.IsLateral=true #Auxiliary CACHE (disk cache) jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheF actory jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.Indexe dDiskCacheAttributes jcs.auxiliary.DC.attributes.DiskPath=e:\jcscache jcs.auxiliary.DC.attributes.MaxKeySize=10000000 jcs.auxiliary.DC.attributes.MaxPurgatorySize=1000 jcs.region.testCache=DC jcs.region.testCache.cacheattributes=org.apache.jcs.engine.CompositeCach eAttributes jcs.region.testCache.cacheattributes.MaxObjects=0 jcs.region.testCache.cacheattributes.MemoryCacheName=org.apache.jcs.engi ne.memory.lru.LRUMemoryCache jcs.region.testCache.cacheattributes.UseMemoryShrinker=false jcs.region.testCache.cacheattributes.DiskUsagePattern=UPDATE jcs.region.testCache.elementattributes=org.apache.jcs.engine.ElementAttr ibutes jcs.region.testCache.elementattributes.IsEternal=true jcs.region.testCache.elementattributes.MaxLifeSeconds=-1 jcs.region.testCache.elementattributes.IdleTime=-1 jcs.region.testCache.elementattributes.IsSpool=true jcs.region.testCache.elementattributes.IsRemote=false jcs.region.testCache.elementattributes.IsLateral=false try { cache = JCS.getInstance( cacheRegionName ); } catch ( CacheException e ) { e.printStackTrace(); } for (int i=0; i<10000000; i++) { City city = new City(); try { cache.put( ""+i, city ); } catch ( Exception e ) { e.printStackTrace(); } if (i % 4000 == 0) { // yield so disk thread can get the cpu Thread.yield(); System.out.println(cache.getStats()); } } - Ron http://sourceforge.net/projects/ajax4jmx/ -- Ist Ihr Browser Vista-kompatibel?
