[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-4228 Preferred master node for HASingleton

by galder.zamarreno＠jboss.com

This came out of a discussion with Brian: HASingletonElectionPolicy should only contain methods that actually called from the HASingletonSupport/HASingletonController classes so that they can inject attributes to the election policy that users don't have to specify in the ha singleton election policy bean definition.Therefore, /** | * Sets the preferred master node. As long as the preferred master node | * presents in the cluster, it will be always selected as master node, | * no matter what the election policy is. | * @param node String format of ip_address:port_number | */ | void setPreferredMaster(String node); | | String getPreferredMaster(); methods should not live in HASingletonElectionPolicy, but instead in HASingletonElectionPolicySimple. They could be defined by HASingletonElectionPolicySimpleMBean and implemented by HASingletonElectionPolicySimple, depending whether it makes sense to be accessible and potentially modified at runtime. Shall I reopen JBAS-4228 or create a new JIRA? If agreed, the change will happen for JBoss 5. What do we wanna do about 4.2? Leave it as it is?

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-4919 - ha singletons in heterogenous topologies

by galder.zamarreno＠jboss.com

I've switched to pickSingleton(List) and managed to get the singleton election tests running successfully again. A few notes/questions: 1.- I could do with having a method in DRM like this: public List<ClusterNode> lookupReplicantsNodes(String key); And deprecate lookupReplicantsNodeNames() as it returns a List of String names, which could still be accessible via ClusterNode.getName(). Otherwise, building the List is inefficient. I have to take the singleton name, look up the List of Cluster Node names, and with that list, take ClusterNode list from the partition and match them to create a brand new ClusterNode list with the nodes where the singleton are running. ugh 2.- The code did not inject the ha partition and singleton name into the election policy. I have done this by overriding HASingletonSupport.startService() and assign before super.startService(). I have my doubts whether this is the best place to do this, so feel free to flame me: @Override | protected void startService() throws Exception | { | if (mElectionPolicyMB != null) | { | mElectionPolicyMB.setHAPartition(getHAPartition()); | mElectionPolicyMB.setSingletonName(getServiceHAName()); | } | | super.startService(); | } 3.- HASingletonSupport does not have access to the singleton object, but we could override startService in HASC again and do something like: @Override | protected void startService() throws Exception | { | if (getElectionPolicy() != null) | { | getElectionPolicy.setSingletonObject(mSingleton); | } | | super.startService(); | } 4.- TODO: Might be worth creating a test with 3 cluster nodes and have a singleton deployed in two.

[Design of JBoss Tools (dev)] - Re: JBoss AS - Starting, Stopping, Polling in AS 5

by rob.stryker＠jboss.com

Example Full command from command line: /home/rob/apps/java/jdk1.6.0_02/bin/java -Dprogram.name=run.sh -server -Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true -Djava.endorsed.dirs=/home/rob/apps/jboss/jboss-4.2.0.GA/lib/endorsed -classpath /home/rob/apps/jboss/jboss-4.2.0.GA/bin/run.jar:/home/rob/apps/java/jdk1.6.0_02/lib/tools.jar org.jboss.Main >>The question is, what builds the full java command to launch the server? In the tooling? heh... as of now nothing. The closest we come to building a full command is making sure IPv4Stack is preferred where it needs to be. I'll make a JIRA to make sure I add an API for complete script mimicking. >he jmx access to the DeploymentScanner does not exist as that bean is gone, and it would not work across server restarts since the change would not be persisted by default. Our main use case here is to be able to stop the server from scanning, then we update our exploded deployed application incrementally without the server recognizing only half the changes, and then let the server resume scanning. If there'll be another way to do it in JBoss 5, that'd be great, but the primary goal is that the server doesn't try to reload an updating application while it's still being changed by us. Also, a way, either through JMX or some other method, to determine when the application has been completely loaded by the server, so that our tools can automatically open the web page for it. RIght now we open the web page right after we deploy, but often times the server hasn't reloaded the app yet and the user gets an unchanged page or an error page.

[Design of JBoss ESB] - Re: Web service security callbacks

by heiko.braun＠jboss.com

However, if this doesn't lead to an instant solution ;) I'll reschedule the related issue for subsequent releases. Maybe we find some time to talk about this at the dev conference in Orlando.

[Design of JBoss ESB] - Re: Web service security callbacks

by heiko.braun＠jboss.com

Well, it works a little different. The container integration needs to supply a WebServiceContextFactory implementation, which is responsible to provide a WebServiceContext implementation particular to the invocation. See [1] for further explanations. As I pointed out several times [2], we need to consider ESB a container on it's own and provide a customized integration layer for it. I think the current SPI will do. Regarding the JMS example: It's a EJB invocation the delegates to the EJBContext. Thus no problem there.

[Deployers on JBoss (Deployers/JBoss)] - Explicit depends tag on the bean definitions for the deploye

by anil.saldhana＠jboss.com

Scott mentioned that there is no need to add explicit depends tag on the bean definitions for the deployers. Eg: The EJB2xDeployer has a depends tag on SecurityDeployer. The WebServiceDeployerEJB has a depends tag on EJB2xDeployer and EJB3Deployer. Should we be getting rid of these soon?

[Design of Messaging on JBoss (Messaging/JBoss)] - JBMESSAGING-1216 - ClusteredTopic returning Queue instead of

by clebert.suconic＠jboss.com

On this bug, when you have a MessageSubscriber, when the message is transfered over the Cluster, sometimes you get instances of Topic. (condition replicated on DistributedTest::testDestinationTypeOnMessage, which is just Phillip's test converted as a testcase) Looking at MessageCustomer, it aways create producers and consumers as Queues. To fix that I'm doing these changes: I - Exposing the isQueue attribute on the Condition interface II - MessageSucker will now receive the condition as well (besides just the Queue) III - MessageSucker will create a Topic or Queue according to the condition. | - JBossDestination dest = new JBossQueue(localQueue.getName(), true); | + JBossDestination dest = condition.isQueue()?new JBossQueue(localQueue.getName(), true): new JBossTopic(localQueue.getName(), true); | producer = localSession.createProducerDelegate(dest); Anyone sees any problem on the fix as described?

[Design of JBoss/Tomcat Integration] - Re: JspRuntimeContext has invalid assumption of URLClassLoad

by remy.maucherat＠jboss.com

I just removed the URL CL hardcoding (will be in the next jboss web build), but to maintain current functionality I would recommend that the CL used by the web layer provides URL CL functionality.
