Dynamic Cache Service
Package: applicationserver
Supertype: Service
Classifier ID: -1
Instance class name: * Unspecified *
Instance class: * Unspecified *
Attributes Summary defaultPriority : EInt The default priority for servlets that can be cached. It determines how long an entry will stay in a full cache. The recommended value is 1. hashSize : EInt Specifies a hash size when disk offload is enabled. Valid values are powers of 2 (1, 2, 4, 8, ...) cacheSize : EInt A positive integer defining the maximum number of entries the cache will hold. Values are usually in the thousands, with no set maximum or minimum. cacheProvider : EString @since 7.0.0 Allows the user to configure the server to use the Dynamic Cache or a stack product/third party cache provider. enableCacheReplication : EBoolean @since 6.0.0 replicationType : DynamicCacheReplicationKind * No description is available * pushFrequency : EInt A time interval, specified in seconds which is used when replication type is PUSH. Default value is 0 enableDiskOffload : EBoolean Enables disk offloading. diskOffloadLocation : EString Specifies a directory used for disk offload. flushToDiskOnStop : EBoolean @since 6.0.0 enableTagLevelCaching : EBoolean @since 6.0.0 diskCachePerformanceLevel : DiskCachePerformanceKind Specifies the level of performance required by this disk cache. This setting is applicable only if "enableDiskOffload" is specified for the cache. Performance levels determine how memory resources should should be used on background activity such as cache cleanup, expiration, garbage collection etc.. High performance indicates that all metadata will be kept in memory. Balanced performance indicates some metadata will be kept in memory. This is the default performance setting, and will provide an optimal balance of performance and memory usage for most users. Low performance indicates that limited metadata will be kept in memory. Custom performance indicates that the Administrator will explicitly configure the memory settings that will be used to support the above background activity. The Administrator will set these values via the "DiskCacheCustomPerformanceSettings" object. diskCacheSizeInGB : EInt M disk cache size in GB. A value of 0 indicates unlimited size. Valid values are 0 or 3 to MAXINT. diskCacheSizeInEntries : EInt M disk cache size in number of entries. A value of 0 indicates unlimited size. Valid values are 0 to MAXINT. diskCacheEntrySizeInMB : EInt M size of an individual cache entry in MB. Any cache entry larger than this, when evicted from memory, will not be offloaded to disk. A value of 0 indicates unlimited size. Valid values are 0 to MAXINT. diskCacheCleanupFrequency : EInt Specifies a value for the disk cache cleanup frequency in minutes. If this value is set to 0, the cleanup is run only at midnight. This setting applies only when the Disk Offload Performance Level is LOW, BALANCED or CUSTOM. The HIGH performance level will not require disk cleanup at all, and this value will be ignored. Valid values are 0 to 1440 memoryCacheSizeInMB : EInt @since 7.0.0 M memory cache size in MB. cacheGroups : ExternalCacheGroup * Define sets of external caches WebSphere should control cacheReplication : DRSSettings @ * No description is available * diskCacheCustomPerformanceSettings : DiskCacheCustomPerformanceSettings @ * No description is available * diskCacheEvictionPolicy : DiskCacheEvictionPolicy @ * No description is available * memoryCacheEvictionPolicy : MemoryCacheEvictionPolicy @ * No description is available *
