[jboss-user] [JBossCache] - Manual eviction not working
Hi all,
I'm trying to evict manualy all nodes from memory cache to cache loader (mysql
datastore).
I'm doing this as I want to keep data from cache even if I shutdown JBoss server, so I
want to store physicaly datas , and when I start Jboss another time, it will bring up all
datas from cacheloader.
This is the code :
public void backupAllCache() {
| this.log.info("launching backup cache");
| Fqn fqn = Fqn.fromString("/root/");
| try {
| Node root = this.cache.get(new Fqn(fqn, "smu"));
| Map childs = root.getChildren();
| Set keys = childs.keySet();
| for (Iterator iterator = keys.iterator(); iterator.hasNext();) {
| Object object = (Object) iterator.next();
| String k = (String)object;
| Node child = (Node)childs.get(k);
| this.cache.evict(child.getFqn());
| }
| } catch (CacheException e) {
| e.printStackTrace();
| }
| catch (Exception e) {
| e.printStackTrace();
| }
| }
The nodes are deleted from memory but doesn't go to cache loader.
Here is my config cache :
<?xml version="1.0" encoding="UTF-8" ?>
| <server>
| <classpath codebase="./lib" archives="jboss-cache.jar,
jgroups.jar" />
| <mbean code="org.jboss.cache.aop.PojoCache"
name="jboss.cache:service=PojoCache">
| <depends>jboss:service=Naming</depends>
| <depends>jboss:service=TransactionManager</depends>
| <depends>jboss.jca:service=DataSourceBinding,name=my-ds</depends>
|
| <attribute
name="TransactionManagerLookupClass">org.jboss.cache.JBossTransactionManagerLookup</attribute>
| <attribute name="NodeLockingScheme">PESSIMISTIC</attribute>
| <attribute
name="IsolationLevel">REPEATABLE_READ</attribute>
|
| <attribute name="CacheMode">LOCAL</attribute>
|
| <attribute name="LockAcquisitionTimeout">15000</attribute>
| <attribute
name="EvictionPolicyClass">org.jboss.cache.aop.eviction.AopLRUPolicy</attribute>
| <attribute name="EvictionPolicyConfig">

| <attribute
name="wakeUpIntervalSeconds">2</attribute>
| <!-- Cache wide default -->
| <region name="/_default_">
| <attribute name="maxNodes">100000</attribute>
| <attribute
name="timeToLiveSeconds">0</attribute>
| </region>
| <region name="/root/smu">
| <attribute name="maxNodes">100000</attribute>
| <attribute
name="timeToLiveSeconds">0</attribute>
| </region>
| </config>
| </attribute>
| <attribute name="CacheLoaderConfiguration">
| <config>
| <passivation>true</passivation>
| <shared>false</shared>
| <preload></preload>
| <cacheloader>
|
<class>org.jboss.cache.loader.JDBCCacheLoader</class>
| <properties>
| cache.jdbc.datasource=java:/my-ds
| cache.jdbc.table.drop=false
| </properties>
| <async>false</async>
| <fetchPersistentState>true</fetchPersistentState>
| <ignoreModifications>false</ignoreModifications>
| </cacheloader>
| </config>
| </attribute>
| </mbean>
| </server>
So, to conclude, if anybody knows why this manual evicting is not working ??
Otherelse, If somebody knows also a simpliest way to evict automaticly all nodes from
memory to cacheloader when Jboss shutdown ????
Thanks all!
ps : I use Jboss 4.05GA and JbossCache 1.4.1 SP3.
