[JBoss Cache] New message: "Preload second level cache"

by Johan Kumps

User development, A new message was posted in the thread "Preload second level cache": http://community.jboss.org/message/518903#518903 Author : Johan Kumps Profile : http://community.jboss.org/people/johan.kumps Message: -------------------------------------------------------------- Hi, We are currently busy with architecting a solution using JPA/hibernate. We want to use JBossCache as second level cache because all data is rather static. Due to the fact that the data is static we would like to be able to preload the data in the cache. The documentation states however that it is a bad practice to use a CacheLoader when implementing a second level cache using JBossCache. So our question is how we can preload our second level cache? It's important that this is done only once whitin the cluster. Looking forward to your ideas... Kind regards, Johan, -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/518903#518903

[JBoss Messaging] New message: "Re: Problem with cluster failover."

by Krystian Siuda

User development, A new message was posted in the thread "Problem with cluster failover.": http://community.jboss.org/message/518899#518899 Author : Krystian Siuda Profile : http://community.jboss.org/people/ksiuda Message: -------------------------------------------------------------- Hi, When an Exception is thrown dealing with Connection/Session/Producer(in the "sender" thread)/Consumer(in the "receiver" thread) the connection is restarted compleatly. The Exception you qoted ("Maximum number of failover attempts exceeded.") has been thrown only by the "receiver" thread, I think that the "prodcuer" was allready blocked at that time (I can check it to be sure if it's revelant). This is how I handle Exceptions in "sender" ("receiver" is very simmilar, this is very dirty code..sorry): public static void sendWrap(ConnectionFactory cf, Destination target) { for(;;) { // just loop forever try { Thread.sleep(1000); send(cf, target); } catch (Exception e) { if(e instanceof InterruptedException) { LOGGER.info("exiting sender", e); return; } else { LOGGER.warn("send got exception", e); } } } } and the "send" method: public static void send(ConnectionFactory cf, Destination target) throws Exception { Connection connection = null; try { connection = cf.createConnection("ecm-user", "ecm-user"); Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE); MessageProducer producer = session.createProducer(target); connection.start(); LOGGER.info("Sending"); for(;;) { // some uniq id generation was here TextMessage message = session.createTextMessage(id + "~" + new Date() + "~" + GarbageGenerator.getGarbage()); message.setJMSDeliveryMode(DeliveryMode.PERSISTENT); producer.send(message); if(LOGGER.isTraceEnabled()) { LOGGER.trace("Sent message no: " + id + " id: " + message.getJMSMessageID() + " : " + message.getText()); } else { LOGGER.info("Sent message no: " + id + " id: " + message.getJMSMessageID()); } Thread.sleep(500); if(Thread.interrupted()) { LOGGER.info("sender interrupted"); throw new InterruptedException(); } } } finally { if(connection != null) { connection.close(); } } } The "receiver" and "sender" threads are using two separate ConnectionFactories and Destinations. Those are taken from two separate JNDI lookups. That's because I needed a tool that can send&receive messages from different servers. This is the initialization code: Properties senderProps = new Properties(); senderProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); senderProps.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); senderProps.put(Context.PROVIDER_URL, senderJNP); Properties receiverProps = new Properties(); receiverProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); receiverProps.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); receiverProps.put(Context.PROVIDER_URL, receiverJNP); // Step 1. Create an initial context to perform the JNDI lookup. senderInitialContext = new InitialContext(senderProps); receiverInitialContext = new InitialContext(receiverProps); // Step 3. Perform a lookup on the Connection Factory final ConnectionFactory senderConnectionFactory = (ConnectionFactory)senderInitialContext.lookup(senderCF); final ConnectionFactory receiverConnectionFactory = (ConnectionFactory)senderInitialContext.lookup(receiverCF); // Step 2. Perfom a lookup on the queue final Destination senderTarget = (Destination)senderInitialContext.lookup(senderDest); final Destination receiverTarget = (Destination)senderInitialContext.lookup(receiverDest); Same situation takes place when I'm using HA-JNDI for the lookup (port 1100).

[Beginner's Corner] New message: "JBoss won't start on run.bat"

by Riccardo Blumenthal

User development, A new message was posted in the thread "JBoss won't start on run.bat": http://community.jboss.org/message/518895#518895 Author : Riccardo Blumenthal Profile : http://community.jboss.org/people/neron17 Message: -------------------------------------------------------------- Hei community I want to get my JBoss 5.1.0 get started on Windows but somehow it won't work anymore. I already had it running in a shell and then integrated it into Eclipse. It's still running in Eclipse though but I cannot run it outside in a shell anymore via the run.bat. The output looks as follows: ===== C:\Programme\JBoss\jboss-5.1.0.GA\bin>run Calling C:\Programme\JBoss\jboss-5.1.0.GA\bin\run.conf.bat C:\Programme\JBoss\jboss-5.1.0.GA\bin>run ===== I have no idea why nothing is happening. Also redownloaded JBoss and installed it again..still the same. Anyone has an idea?

[JBoss Microcontainer Development] New message: "Re: another annotation scanner requirement"

by Ales Justin

User development, A new message was posted in the thread "another annotation scanner requirement": http://community.jboss.org/message/518894#518894 Author : Ales Justin Profile : http://community.jboss.org/people/alesj Message: -------------------------------------------------------------- > Well, I want something usable now so I can finish my resteasy integration. I'd be willing to both patch whatever is going to be in M2 and expand on whatever is going to be there in the future. For M2 you'll still need to do it the old/slow way. For M3 I'll make sure we already have some working more-usable/more-optimal solution. Porting your lookup mechanism afterwards should be easy. > Also, you need facilities to state that a jar/deployment shouldnt' be scanned. My bet is that most of the jar files that come with JBoss won't need to be scanned. This already exists, in various forms. * empty http://www.jboss.org/community/docs/DOC-13178 * list jar/deployment in excluded list: http://anonsvn.jboss.org/repos/jbossas/trunk/server/src/etc/deployers/met... If either of these two mechanisms is up-to-date wrt our jars/deployments, we shouldn't be scanning anything already at boot time. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/518894#518894

[Performance Tuning] New message: "Re: CPU usage increases daily for JBoss PID, reaches to 100% after 10 days."

by navkalp varshney

User development, A new message was posted in the thread "CPU usage increases daily for JBoss PID, reaches to 100% after 10 days.": http://community.jboss.org/message/518889#518889 Author : navkalp varshney Profile : http://community.jboss.org/people/navkalp Message: -------------------------------------------------------------- Thanks very much, It might have helped lot of people like me who are trying to learn seeing thread dumps. I doubt that Hashmap is corrupted. the reason is, we are using struts2, which handles every request in different thread, hence different thread is using different hashmap, Also the result screen does not have any issue althoguh being accessed simulatneously by 400 to 500 users. Still I can not rule out the issue pointed out by you and will dig into more. Thanks a lot for you people again. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/518889#518889
