When a passivated object state is activated and modified , the modified state is not passivated again . I am using passivation as false to retain the object in secondary cache but the object may get modified in memory any time . Modified state of the object is not getting passivated to file system . Any idea? .Attaching the jboss config file. <!-- Cache Loader configuration block --> <attribute name="CacheLoaderConfig"> <config> <!-- if passivation is true, only the first cache loader is used; the rest are ignored --> <!-- passivation should be false to retain the data in secondary cache otherwise node will be deleted after loading to the memery --> <passivation>false</passivation> <!-- comma delimited FQNs to preload --> <!-- <preload>/ASOF_POSITION</preload> --> <shared>false</shared> <!-- we can now have multiple cache loaders, which get chained --> <cacheloader> <class>org.jboss.cache.loader.FileCacheLoader</class> <properties> location=e:/trash/jbosscache </properties> <!-- whether the cache loader writes are asynchronous --> <async>true</async> <!-- if set to true, purges the contents of this cache loader when the cache starts up. Defaults to false. --> <purgeOnStartup>false</purgeOnStartup> <!-- only one cache loader in the chain may set fetchPersistentState to true. An exception is thrown if more than one cache loader sets this to true. --> <fetchPersistentState>true</fetchPersistentState> <!-- determines whether this cache loader ignores writes - defaults to false. --> <ignoreModifications>false</ignoreModifications> </cacheloader> </config> </attribute> Regards, Kavitha Durai, The Rohatyn Group, 212-984-3512.
