Passivation not working with POJO Changes
by Kavitha Durai
When passivation is set to false, changes in POJO are not passivated .
What is missing?
Class implements Serializable ---- not replicable .
--------------------------------------------------------
Object rc = cacheManager.find( cacheKey );
//modify rc
rc.setDate(date);
Will the above change passivated to file system (FileCache laoder is
configured) on its own or do I need to detach and attach the object
again here.I am not seeing the changes passivated to secondary cache .
Is the below code required?
//cacheManager.detach(cacheKey)
//cacheManager.attach(cacheKey)
-----------------------------------------------------------------------
<!-- 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>

Modified Object state not passivated
by Kavitha Durai
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.
