[jboss-user] [JBoss Cache: Core Edition] - I don't Think I am doing this Correct
I am playing around with JBOSS Cache and do not know if I am doing this
correct. When I do a FindAllI can see that the cache is populated when i
do a printDetail in the JMXConsole. However, when I do bench testing and keep
calling the same method, FindAll..., I do not seen any performance increase.
Is it still making a call to the database? It takes the same amount of time as
non-cached implementation. Below is the entity i am using. It's a view in one
of our tables that contains abour 20,000+ rows that I would like to have cached.
Taken from Hibernate tutorial - : This call actually will fill the cache when
it is first run. but as I do consecutive calls to this, i do not see a
performance increase. They all take the same amount of time as the initial
call. Is this the wrong thing to do?

Are there certain methods that I can call that will generate this export XML, or do I need to construct it myself? What would be the best approach to do this?

[jboss-user] [JBossCache] - Re: JBOSS Cache vs Gigaspaces
So, I have a Cache (JBOSS) that is filled with nRows. Now, the problem is to get this data into some format that can populate a .NET Grid on a windows front end app. Is it possible to have a WS that can make a call and return the data in XML format?

[jboss-user] [JBossCache] - Re: JBOSS Cache vs Gigaspaces
In either case though, how would I accomplish the following: Our client application will be written in C# (visual studio), and utilize the devexpress grid. Using GigaSpaces, I believe that they have APIs for C# .NET. Using JBOSSCache, what would be the best approach to populate the Data Grid?

[jboss-user] [JBossCache] - Re: JBOSS Cache vs Gigaspaces
All data is in my own schema. However, it is populated and maintained by another external process (besides our current client application as well). We have a service that currently monitors, what we call an audit table. When rows are added to this audit table, certain triggers are fired depending on weather it is an edit, or insert type of audit. Inserts will create new entries into our schema, and edits will update the existing data in our schema. Our client app updates and maintains our schema directly, but for only edit purposes. So, when these inserts are done, we would also like to create that new record in the cache, and have our clients apps updated as well. Currently, this is done by client JMS subscriptions. Same as the edits.

[jboss-user] [JBossCache] - JBOSS Cache vs Gigaspaces
I would like to know if jboss cache would be suitable for the following. We have a view that returns a very large recordset. It can take up to 2-3 minutes for the data to actually be pulled from our DB to our client app. Can jboss cache be used to store this data in a central location that N number of clients can access? The cache would need to always be available. Also, is it possible to keep the cache current when new records, and or edits are made, and then broadcast these changes to our users? I am new at using cache managers and just want to know if this scenario would work with jboss cache? Much thanks.

[jboss-user] [JBoss Messaging] - Connection not authorized to addMessages to destination
Newbee here. Doing a simple wholesaler and retaler jms example. 1) wholesaler creates a temporarytopic and subscribes to it. 2) when wholesaler publishes a message, it sets the message's JMSReplyTo to the temporaryTopic. 3) When retailer receives a message from wholesaler, it does some stuff and then based on calculations, it will publish a message to the message.getJMSReplyTo(). Here is the basic code snipets.. wholesaler: hotDealsTopic = (Topic) jndi.lookup(topic/Hot Deals); publisher = pubSession.createPublisher(hotDealsTopic); buyOrdersTopic = subSession.createTemporaryTopic(); subscriber = subSession.createSubscriber(buyOrdersTopic); subscriber.setMessageListener(this); when publishing: StreamMessage message = pubSession.createStreamMessage(); message.writeString(dealDesc); message.writeString(itemDesc); message.writeFloat(oldPrice); message.writeFloat(newPrice); message.setStringProperty(Username, username); message.setStringProperty(Itemdesc, itemDesc); message.setJMSReplyTo(buyOrdersTopic); publisher.publish(message, DeliveryMode.PERSISTENT, Message.DEFAULT_PRIORITY,180); Retailer: on Receive and process: TextMessage textMsg = session.createTextMessage(); textMsg.setText(count + + itemDesc); Topic buyTopic = (Topic) message.getJMSReplyTo(); publisher = session.createPublisher(buyTopic); textMsg.setJMSCorrelationID(DurableRetailer); publisher.publish(textMsg, DeliveryMode.PERSISTENT, Message.DEFAULT_PRIORITY, 180); JMSSecurityException: avax.jms.JMSSecurityException: Connection not authorized to addMessages to destination: JMS_TT5 at org.jboss.mq.security.ServerSecurityInterceptor.addMessage(ServerSecurityInterceptor.java:167) at org.jboss.mq.server.TracingInterceptor.addMessage(TracingInterceptor.java:226) at org.jboss.mq.server.JMSServerInvoker.addMessage(JMSServerInvoker.java:112) at org.jboss.mq.il.uil2.ServerSocketManagerHandler.handleMsg(ServerSocketManagerHandler.java:111) at org.jboss.mq.il.uil2.SocketManager$ReadTask.handleMsg(SocketManager.java:395) at org.jboss.mq.il.uil2.msgs.BaseMsg.run(BaseMsg.java:398) at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:732) at java.lang.Thread.run(Thread.java:595) View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4031325#4031325 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4031325 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
