[JBoss Cache] - hibernate-jbosscache2 and mvcc issues

by nithya anand

nithya anand [http://community.jboss.org/people/anandkrish] created the discussion "hibernate-jbosscache2 and mvcc issues" To view the discussion, visit: http://community.jboss.org/message/543483#543483 -------------------------------------------------------------- HI, We opted to implement JbossCache-core-3.x on Local (means not on cluster) since it comes with mvcc. We were on jboss 4.2.3 (with hibernate 3.2) and realized that jbosscache-core- 3 needs hibernate 3.3. So we upgraded to Jboss 5 which comes with jbossCache-core - 3.0.1, Hibernate 3.3.1 and hibernate-jbosscache2 (3.3.1). Issues: 1. Maven dependency conflict: hibernate-jbosscache2 (3.3.1) has a dependency on jbosscache-core-2.1.1.GA. We found that hibernate-jbosscache2 (3.3.2) has a dependency on jbosscache-core-3.x.GA, but we didn't want to mess up with the default jars that comes with JBOSS 5. 2. MVCC: (Caching turned on) Since with all these jar issues I want to make sure that the cache is working with mvcc turned on. But couldn't find any info on log that says that mvcc is turned on. the following is our persistence.xml <persistence-unit name="abcdb"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>MySqlDS</jta-data-source> <properties> <property name="hibernate.show_sql" value="false"/> <property name="hibernate.format_sql" value="false"/> <property name="hibernate.use_sql_comments" value="false"/> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" /> <property name="hibernate.connection.useUnicode" value="true"/> <property name="hibernate.connection.characterEncoding" value="UTF-8"/>  <property name="hibernate.cache.use_second_level_cache" value="true"/> <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.jbc2.MultiplexedJBossCacheRegionFactory"/> <property name="hibernate.cache.region.jbc2.cfg.shared" value="blahblah.xml"/> <property name="hibernate.current_session_context_class" value="jta"/> <property name="jboss.entity.manager.jndi.name" value="java:/abcdb"/> <property name="jboss.entity.manager.factory.jndi.name" value="java:/abcdbfactory"/> <property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/> <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/> </properties> </persistence-unit> 3. I wanted to provide a config file (even though not mandatory) for my JbossCache configuration to make sure mvcc is turned on. But, even if i don't have blahblah.xml on my classpath, it wouldn't complaint. I don't see any error saying that blahblah.xml is missing. Questions: 1. how can I make sure that my jbosscache is running on mvcc mode. 2. whats with the "hibernate.cache.region.jbc2.cfg.shared" value="blahblah.xml" file? do we need it at all? Please answer my questions. Thanks, Anand. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/543483#543483] Start a new discussion in JBoss Cache at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM Development] - discuss about unresolved issues of jBPM 4.4

In my opinion most of the work should be done within couple of weeks so I would say that end of June sounds like a good date for 4.4 release (just to be on safe side). Unfortunately I am not in charge so we have to wait for Alejandro opinion but hopefully we will manage to deliver a stable 4.4 release with bug fixes and so enhancements as well (mainly those that have been already implemented). Besides bug fixing we are trying to put some focus on documentation as well, especially for these elements that have been asked several times on the forum. Please refer to JIRA for the latest status and feel free to comment and vote ... there is still some issues left ;) Cheers, Maciej -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/543475#543475] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - start a process within another process in jbpm 4.3

by Al Nadein

Al Nadein [http://community.jboss.org/people/matrixpooh] replied to the discussion "start a process within another process in jbpm 4.3" To view the discussion, visit: http://community.jboss.org/message/543442#543442 -------------------------------------------------------------- In short, I start a process that happily follows a few steps before it hits a 'wait' state where it's persisted to db. At some point, i have to derive by the rules if any other sub-processes have to be created. Since jbpm provides an option to create only 1 subprocess at a given step, I'm openning subprocesses programmatically, i.e. in *CreateSubprocesses* activity handler: {code} //calculate groups to assign to a swimlane taskAssignees = ...; assigneeGroups.put(SharedConstants.KEY_SWIMLANE_CANDIDATE_GROUPS, taskAssignees); ProcessInstance processInstance = executionService.startProcessInstanceByKey("subprocess_1", assigneeGroups); {/code} Again, all of the above is done in an activity handler of the process that has just been instantiated and hasn't been saved to db yet. Here's a shortened version of my jpdl: {code:xml} <process key="main" name="main" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl"> <start g="5,23,48,48" name="start"> <transition g="141,46:-88,-15" name="open.case" to="Create sub-process"/> </start> <state g="306,193,148,52" name="Wait For Update"> <transition g="-23,-24" name="end" to="end1"/> </state> <custom g="239,26,138,52" name="Create sub-process" class="*CreateSubprocesses*"> <transition g="484,52:-108,-17" name="to-split-paths" to="Wait For Update"/> </custom> <end g="566,493,48,48" name="end1"/> </process> {/code:xml} and one of possible sub-processes (simplified): {code:xml} <?xml version="1.0" encoding="UTF-8"?> <process name="test" key="test" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl"> <swimlane candidate-groups="#{assigned.responsibilities}" name="assigned-group"/> <start name="start1" g="16,21,48,48"> <transition name="to task1" to="task1" g="-17,-20"/> </start> <end name="end1" g="219,17,48,48"/> <task name="task1" g="96,16,92,52" swimlane="assigned-group"> <transition name="to end1" to="end1" g="-20,-19"/> </task> </process> {/code:xml} -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/543442#543442] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Messaging] - Specifying Quality of Service for a message

by Rasikan David

Rasikan David [http://community.jboss.org/people/rdavid] created the discussion "Specifying Quality of Service for a message" To view the discussion, visit: http://community.jboss.org/message/543440#543440 -------------------------------------------------------------- We are using the JBoss messaging publish/subscribe service and need to associate each published message with a traffic class (DSCP) at the IP level based on the topic associated with the message. I see that the bisocket class has a setTrafficClass() method to set the DSCP value for the socket. Is there a way in which the traffic class can be specified when the client publishes a message and have it carried through the protocol stack to the point where the message is sent over the bisocket? If not, can you suggest a way in which a traffic class can be associated with a messaging topic in JBoss? Thanks, Rasikan David. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/543440#543440] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I was asking a pretty basic question: how to close processes from an activity handler of another process. ExecutionService::endProcessInstance() all that I needed. But I ran into another issue doing this call: the processes i need to close are collections of human tasks. All or any of the tasks may be pending at the moment of ending their processes. The call to endProcessInstance() fails with integrity constraint: can't delete "swimlane" records due to "task" child records. Looking into it now. If you have any ideas, would be grately appreciated -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/543438#543438] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
