    Sync cache store data on a defined intervals

    Araz Alipour Newbie

      How is the cache store data updated? I assume the store process is triggered by data change in cache. Is that right? Is it possible to sync cache store data with cache on defined intervals?

          By default the cache stores are updated in the same process thread that updates the cache. To do this periodically (for performance reasons) look at the async attribute of the cache store. Also see the javadocs:

          http://docs.jboss.org/infinispan/4.0/apidocs/org/infinispan/loaders/decorators/AsyncStore.html

            thanks manik. but I came across another problem on creating a cluster. here is my cache config:

            <infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:infinispan:config:4.0">
             <global>
             <transport clusterName="myCluster"/>
             </global>
            
             <default>
             <clustering mode="distribution">
             <l1 enabled="true" lifespan="60000"/>
             <hash numOwners="2" rehashRpcTimeout="60000"/>
             <sync/>
             </clustering>
             </default>
            
             <namedCache name="accounts">
             <eviction wakeUpInterval="5000" maxEntries="1000" strategy="FIFO"/>
             <expiration lifespan="600" maxIdle="1000"/>
             <loaders passivation="false" shared="false" preload="true">
             <loader class="com.magfa.gateway.dao.infinispan.jdbcstore.AccountJdbcCacheStore" fetchPersistentState="true"
             ignoreModifications="false" purgeOnStartup="true">
             <properties/>
             <singletonStore enabled="true" pushStateWhenCoordinator="true" pushStateTimeout="20000"/>
             <async enabled="true" threadPoolSize="5"/>
             </loader>
             </loaders>
             </namedCache>
            </infinispan>
            


            when I try to update the cache I get this exception:

            and this is how I try to update cache on InfinispanBillingDao.decreseCredit: 143 :

            cache.getAdvancedCache().replace(accountId, oldAccount, newAccount);

            anyone knows what the problem might be?

              Tune your eviction to be more aggressive? Or use a larger heap size?

                Araz Alipour Newbie

                It doesn't solve the problem. There must be something wrong with jgroups I assume. Changed accounts update to this:

                cache.remove(accountId);
                cache.put(accountId, newAccount);

                and the exception changed to TimeoutException:

                      With BETA1 OutOfMemory error happens on cache sync process. if an item is removed or replaced in the cache. Trying with ALPHA6 the error occures when a cache node starts and tries to join the cluster.
                      here is the stack trace using ALPHA6 if it helps:

                        What actually is in your newAccount instance? Can you describe the object a bit?

                          It's an instance of Account that it's credit is reduced. The Account class is:

                            It is an instance of Account class. The Account class is:

                            public class Account implements Comparable, Serializable {
                            private final long id;
                            private final int hashCode;
                            private final String name;
                            private volatile double credit;
                            private final AtomicLong sent;
                            private final AtomicLong received;
                            private final AtomicLong rejectedSent;
                            private final AtomicLong rejectedReceived;
                            private final double cost;
                            private final boolean postpaid;
                            private final boolean prepaid;
                            ...
                            with getters and setters

                              Also is there any way you can post the ENTIRE stack trace with the object trace at the bottom?

                                On top of what Manik is requesting, what JDK are you running?

                                  As well as providing the JDK information, in order to get object trace information that David is refering to (this trace info is explained in http://www.jboss.org/community/wiki/infinispantechnicalfaqs#How_do_I_get_more_information_on_marshallingunmarshalling_exceptions, please build infinispan trunk calling 'mvn install' (svn trunk is located in http://anonsvn.jboss.org/repos/infinispan/trunk/) and try again.
