RE: [JCS] the data becomes zero
Hi Thomas, Thanks for the response. Yes, the reset happens during normal operations, but I don't see any error messages either in the application log or the server log (we use weblogic 9.2). Yes, I will try download the code from trunk and update you on the impact.

[JCS] the data becomes zero
Hi All, I have been using JCS for some time now, I think I have encountered a major problem, i.e... We are using IndexedDiskCache, the size of the data file in disk is about 250MB, the problem is sometimes, the data gets erased from the disk (the data file size becomes zero) without any error message any where? Snippet of the configuration file is placed below, does any anybody faced this problem or is it a known issue or is there any work around, please let me know ### Indexed Disk Cache ### jcs.auxiliary.indexedDiskCache=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheFactory jcs.auxiliary.indexedDiskCache.attributes=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheAttributes jcs.auxiliary.indexedDiskCache.attributes.DiskPath=/mydata jcs.auxiliary.indexedDiskCache.attributes.MaxPurgatorySize=-1 jcs.auxiliary.indexedDiskCache.attributes.MaxKeySize=50 jcs.auxiliary.indexedDiskCache.attributes.MaxRecycleBinSize=5 jcs.auxiliary.indexedDiskCache.attributes.OptimizeAtRemoveCount=30 jcs.auxiliary.indexedDiskCache.attributes.EventQueueType=POOLED jcs.auxiliary.indexedDiskCache.attributes.EventQueuePoolName=indexedDiskCacheQueuePool jcs.auxiliary.indexedDiskCache.attributes.OptimizeOnShutdown=true ### CACHE REGION - myRegion ### jcs.region.myRegion=indexedDiskCache,failOverCache jcs.region.myRegion.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes jcs.region.myRegion.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache jcs.region.myRegion.cacheattributes.MaxObjects=500 jcs.region.myRegion.cacheattributes.UseMemoryShrinker=true jcs.region.myRegion.cacheattributes.ShrinkerIntervalSeconds=5 jcs.region.myRegion.cacheattributes.MaxMemoryIdleTimeSeconds=5 jcs.region.myRegion.cacheattributes.DiskUsagePatternName=UPDATE Regards, Vijay This message contains information that may be privileged or confidential and is the property of the Capgemini Group.

Does this happen during normal use or only at restart? The restart mechanism is somewhat picky concerning problems in the file and tends to reset the data file then.
