[Clustering/JBoss] - Re: How to make field-granularity-session-cache the default

by bstansberry＠jboss.com

The default clustering behavior in AS 5 can be controlled via the server/XXX/deployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml file. | <bean name="WebAppClusteringDefaultsDeployer" | class="org.jboss.web.tomcat.service.deployers.ClusteringDefaultsDeployer"> | |  | <property name="cacheName">standard-session-cache</property> |  | <property name="fieldGranularityCacheName">field-granularity-session-cache</property> | | .... | | <property name="replicationGranularity">SESSION</property> | | .... | | </bean> | Change replicationGranularity to FIELD and you'll get FIELD by default, unless you configure something else in the app's jboss-web.xml. If you want field-granularity-session-cache to be used by default even if you use SESSION or ATTRIBUTE granularity, change the value of the "cacheName" property. Although I'd recommend adding your own cache config or tweaking standard-session-cache to match what you want. Solely because using a config named "field-granularity-..." for non-field-granularity will confuse someone some day. :) I haven't revamped the FIELD granularity section of the guide yet. :( The AS now uses the standard POJO Cache annotation instead of @AopMarker. It is @org.jboss.cache.pojo.annotation.Replicable. Re: using aopc, you can also use load time weaving. See http://www.jboss.org/jbossaop/docs/2.0.0.GA/docs/aspect-framework/referen... for some discussion of weaving options. There are a couple details in there that are a bit off from AS 5.1 but it's useful. Here's a quick summary of what I did to get load-time weaving for a FIELD granularity web app: 1) Edit server/all/conf/bootstrap/aop.xml's AspectManager bean: | <property name="enableLoadtimeWeaving">true</property> | <property name="include">com.bar., com.bar.</property> | <property name="exclude">org.</property> The first is self-evident. :) The second is where you list the packages you for sure want AOP to look at for load-time weaving. The third is packages for sure *not* to look at. By default that was "org.jboss." but when I experimented I got complaints about some stuff in org.richfaces in the admin-console.war, so I changed it to just "org." 2) Copy the pluggable-instrumentor.jar to the bin/ dir from server/all/deployers/jboss-aop-jboss5.deployer 3) Edit run.conf and add JAVA_OPTS="$JAVA_OPTS -javaagent:pluggable-instrumentor.jar" View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4237765#4237765 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4237765

[JNDI/Naming/Network] - Re: Migrating 4.2.3.GA to 5.1.0.GA - JNDI missing?

by kennardconsulting

jaikiran, Yes, that worked. Terrific. Thank you so much. If I may suggest, though, leaving off the namespace from <ejb-jar> is not so weird. Lots of examples on the Web do that, and it used to work in JBoss 4. If your ejb-jar.xml is machine generated it'll probably have a namespace, but many hand-written ejb-jar.xml's may not. Perhaps some more informative warning message would be helpful? Just a suggestion. Regards, Richard.

It starts in maximum 3 mins. but as I mount the content from NAS and restart the node, it took too much time and up in 45 mins. I don't know the reason of it. Can you please help. I see in nohup that Jboss is waiting for something at the following point : 19:36:00,096 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:jboss-log4j.xml 19:36:00,998 INFO [TransactionManagerService] JBossTS Transaction Service (JTA version) - JBoss Inc. 19:36:00,998 INFO [TransactionManagerService] Setting up property manager MBean and JMX layer 19:36:01,340 INFO [TransactionManagerService] Starting recovery manager 19:36:01,773 INFO [TransactionManagerService] Recovery manager started 19:36:01,773 INFO [TransactionManagerService] Binding TransactionManager JNDI Reference Please suggest what should I do to resolve this problem.

[JBoss Messaging] - Re: getting messages on one node of cluster

by mhossein

I didn't know you could do that with JBM. So you can just deploy your MDB in a sar project in deploy-hasingleton and it works?

[Tomcat, HTTPD, Servlets & JSP] - SSO session destroyed using a4j:poll

by pablo.fraga1975

Hi, I am using JBoss 4.2.0, all conf, ClusterdSSOValve with cookiedomain, ajax4jsf, richfaces 3.3.0 GA and a4j:poll component in some jsp pages, the whole thing in a production environment that receives more than 400.000 tx per day. We are experiencing an unexpected behaviour, where we login properly, hit some pages in one of the web apps. then go to another web app. where we have rich graphics in a jsp using a4j:poll component. This page works fine even for hours, refreshing data correctly, our session timeout is 30 minutes (default value), in each request fired by the a4j:poll component the session is accessed, but, after some hours (not always the same time) the whole sessions are destroyed and we can see it because we have implemented HttpSessionListener in each web app and the page freezes. Don't know what is happening and this doesn't happens in our test environment, the difference we could see is the sustained overload. Any more information that you need, just ask me about it. Thanks.

[JBoss Messaging] - Re: How to add a new server in a cluster?` (Repost)

by clebert.suconic＠jboss.com

Were you able to run any of the examples (clustered.. etc)? You wouldn't need to do any syncs for adding new nodes on the cluster. Also, we are releasing a Beta2 probably tomorrow, that will include a few standalone-clusters configs and a new standalone clustered example, that will probably help you on your testing.

[Clustering/JBoss] - Re: Jboss Clustering over TCP

by bstansberry＠jboss.com

TCP definitely doesn't scale as well as UDP multicast. But whether that is a real issue depends on what kind of traffic you have between the nodes. The services that generate a lot of traffic over the JGroups channels are 1) HttpSession replication 2) EJB StatefulSessionBean replication 3) Hibernate/JPA entity caching. 1) and 2) can be made highly scalable by using buddy replication. 3) is more complex, but there are things you can do as well (use INVALIDATION_SYNC, don't cache query result sets, don't cache entities that are frequently updated.)
