[Performance Tuning] - Re: Performance Issue with large chunk of data retreival.

by mark.spritzler

OK, I am posting this as just me, not who I work for. :) First, tell me who the person is that will actually ready that huge report? Must be one of the fastest speed readers in the world. OK, So first, reports like these should be run over-night, not as ad-hoc. 2. There are products out there that generate reports like these, not necessarily in Java (did I just say that). Anyway they are products designed specifically for these types of reports, and therefore are "the right tool for the job" and not trying to pound a square peg into a round hole with a straw. 3. You might want to handle the data in batches, only bring down enough records at a time to do one page, then release that data to free up memory, and get the next page, and build up the report like that to stay away from out of memory issues. Now this will slow it down, but then again at this point you don't even get the report done. Personally, I'd look for a product that does huge reports, that that is what they were built for, rather than forcing a bad solution.

[Installation, Configuration & DEPLOYMENT] - Re: jsf for jboss 4.2

by hryhory

Today I had the same problem. To avoid this exception you have to add to your web.xml following lines: <context-param> | <param-name>org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL</param-name> | <param-value>true</param-value> | </context-param> This will disable the built-in jsf implementation (just read server output) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4136689#4136689 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4136689

[Clustering/JBoss] - Re: StackOverflowError when starting JBoss Cluster

by bstansberry＠jboss.com

Sure, binding to an address is valid. If you don't specify an address, for security reasons all services bind to localhost, which is pretty useless for a production system. BTW, setting -Djboss.bind.address with the same value is redundant if you use -b. Have you tried this solution discussed on the JIRA you linked?

[JBoss jBPM] - JbpmException: couldn't delete timers for process instance

by wootenator

I have a very straightforward jBPM prototype where I am using hibernate,and tomcat abd SQL Server database. I get this error sometimes on the second invocation of the same ActionHandler within a graph. I'm just prototyping now. My action handler just makes an update to a text field in the database depending on the object that is passed into the aciton handler. I'm reading about timers and right now I am not using a timer in the prototype. I'd almost like to disable them or do something within the action handler to make sure they are not causing this exception do I can continue with the developmetn of my prototype. The exception comes after the third processInstance.signal() that would take the process to transition to the thrird node in the graph (counting the start node). The graph is below: public static ProcessDefinition getTaskProcessDefinition() { JbpmConfiguration jbpmConfiguration = null; ProcessDefinition processDefinition = null; try{ processDefinition = ProcessDefinition.parseXmlString("<process-definition name='processManualTask'>" + " <start-state name='start'>" + " " + " </start-state>" + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " <end-state name='End' />" + "</process-definition>"); } catch(Exception e) {e.printStackTrace(); } try{ HttpSession sess = FrameworkServices.instance().getSession(); JbpmContext jbpmContext = (JbpmContext) sess.getAttribute("jbpmctx"); if (jbpmContext == null) { jbpmConfiguration = JbpmConfiguration.getInstance(); jbpmContext = jbpmConfiguration.createJbpmContext(); sess.setAttribute("jbpmctx", jbpmContext); } System.out.println("saving process instance"); ProcessDefinition definition = processDefinition.createNewProcessDefinition(); ProcessInstance processInstance = definition.createProcessInstance(); jbpmContext.save(processInstance); Session session = (Session) sess.getAttribute("hibsess"); session.flush(); System.out.println("process instance saved!!!!"); }catch(Exception e) {e.printStackTrace(); } return processDefinition; } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4136684#4136684 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4136684

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Need Urgent help!!!! JDBC Driver class not found: com.my

by jaikiran

anonymous wrote : is it better performance, because some services are deactivated, or is it just lower memory consumption, because some jar files are not loaded? | It depends on which service you deactivate. The "default" profile is the most commonly used. However, if you want to slim down some services which are not required in your application, then you usually create a copy of the default folder and start removing the services. See the http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossASTuningSliming especially the Slimming section for more details.
