[JBoss Cache: Core Edition] - Re: About Merging States on Merge of two sub groups.

by nachiket_patel

Thanks Manik, I think Shutting down and restarting will work in our case, as there is only one writer server, which will be initial host, and only one who will write to cache, so server instance of cache will be correct one always. Only disconnected instance (reader) needs to restart itself, not all others. Which event should be used for this, viewChanged(ViewChangedEvent newView)??, How to identify that i am joined back in cluster??? i think i can use getCreator() (returns Address class, but it does not have getIP or getPort kind of methods..)

[JBoss Cache: Core Edition] - Re: About Merging States on Merge of two sub groups.

by manik.surtani＠jboss.com

Re-syncing is pretty tough and very application-dependent. If you are caching data that can be retrieved externally or recalculated externally, then your best bet is to simply wipe the cache and start again. Otherwise, you could pick one instance as the "correct" version, and shut down and restart all other caches in the cluster so they wipe their "incorrect" state and retrieve state from the one correct instance. Anything beyond these two simplistic approaches will involve actually understanding what is in your state and perhaps attempting to merge and consolidate the data manually.

[JBoss jBPM] - Re: Class Cast Exception while the BPEL Process Ends

by dhanushgopinath

Hi, Inorder to solve this problem, I tried upgrading my jbpm bpel instance to 1.1.1 I ran my process and now it throws a slightly different exception. 17:52:39,153 ERROR [GraphElement] action threw exception: org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory | java.lang.ClassCastException: org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory | at org.jbpm.svc.Services.getServiceFactory(Services.java:131) | at org.jbpm.svc.Services.getService(Services.java:148) | at org.jbpm.svc.Services.getCurrentService(Services.java:94) | at org.jbpm.graph.exe.ProcessInstance.end(ProcessInstance.java:328) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) Now its looking throwing class cast exception for the class EntitySchedulerServiceFactory. Can I some how disable it, as I do not need the scheduler service in my application? If so What should be done so that I can disable it ? Will commenting of the line <service name="scheduler" factory="org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory" /> in jbpm.cfg.xml suffice ? Please let me know.

It will be the new year when i get a chance to look at this again.

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Failed to find persistence unit

by ubersoldat

I still don't know why EJB_3 must know anything about the persistence units that don't belong to it. Anyway, I fixed this by adding a persistence.xml file to the ear. I get a "resource already registered" error at deployment, but things work fine.

[Beginners Corner] - New to JBoss, where to start??

by nachiket_patel

Hello, I am new to JBoss. Just started reading and creating prototypes before one week using JBoss PojoCache eventually learned about JGroups. (Only basics) Based on my little knowledge about JBoss, It is built upon ground level technologies to higher level technologies, like JGroups is used in Cache as well as AppServer, Cache is used for Clustering in AppServer. Aspects(i don't know the JBoss name) are used in Cache. So my question is where to start? What should be the road map of learning about JBoss. What should be the foundation for getting good grip on JBoss?? Should i start with MicroContainer?? or Aspects?? Please share your views with me.

[JBoss Cache: Core Edition] - About Merging States on Merge of two sub groups.

by nachiket_patel

Hello, I am getting more familiar with JBoss Cache. I got very much confused and scared in past 3 to 4 days. Because of zero knowledge of JBoss Cache as well as JGroups. And i was trying to avoid JGroup internals initially, lately ended in poor understanding. But now (I feel) i am much clear in basics of PojoCache and JGroups, still don't know much about Core Cache. Thank you all who helped me, and sorry for putting lots of messages and configuration stacks, i know it's annoying sometimes. I am writing this stuff because i really appreciated your help, and i want to thank you for that, Finally my fear of JBoss is gone. Anyways, What mechanism should be used when i want to copy (or sync to) a particular cache instance (AppInstance 'A') which is initial_host in TCPPING on MERGE. (Because 'B' AppInstance was disconnected from network and come back after Splitting of Cluster) .. ViewChange event of CacheListener should be used?? or some special ReplicationInterceptor ?? And how to re-sync with 'A'? By stopping and starting Cache? or some other option is available??
