[EJB 3.0] - Lazy EJB3.1 timerservice deployment starting JBoss AS 6.0.0.M5

by jaikiran pai

jaikiran pai [http://community.jboss.org/people/jaikiran] created the document: "Lazy EJB3.1 timerservice deployment starting JBoss AS 6.0.0.M5" To view the document, visit: http://community.jboss.org/docs/DOC-15884 -------------------------------------------------------------- h5. Background: EJB3.1 timerservice support was introduced in AS 6.0.0.M4 http://community.jboss.org/docs/DOC-15643 http://community.jboss.org/wiki/EJB31inJBossAS600M4. The implementation is based on JPA (Hibernate as the provider in JBoss AS). This added around 3-4 second increase in the boot time of the JBoss AS server, due the initialization involved for deploying the timerservice jar. Since the timerservice was only applicable for EJB3.x deployments, it did not make sense to increase the default boot time if the server doesn't have any EJB3.x deployments. Hence we decided to "lazily" deploy the timerservice. h5. Forum discussion: http://community.jboss.org/thread/155800 http://community.jboss.org/thread/155800 h5. Details: Starting JBoss AS 6.0.0.M5, which was released recently http://community.jboss.org/blogs/donnamishelly/2010/09/24/jboss-as-600m5-... http://community.jboss.org/blogs/donnamishelly/2010/09/24/jboss-as-600m5-..., the jboss-ejb3-timerservice-mk2.jar now resides in JBOSS_HOME/common/deploy folder. This jar will be deployed lazily by the server. The server will deploy this jar only when the first EJB3.x deployment is made available in the server. By default, JBoss AS doesn't ship any EJB3.x deployments and hence the lazy deployment of timerservice jar saves a few seconds of the server boot time. h5. How to disable the "lazy" timerservice deployment: If users want to disable the "lazy" deployment of timerservice and instead deploy it always, irrespective of the presence of an EJB3.x deployment, then follow the steps mentioned below: * Move (cut/paste) jboss-ejb3-timerservice-mk2.jar from JBOSS_HOME/common/deploy to JBOSS_HOME/server/< servername>/deploy folder. Ex: Move it to JBOSS_HOME/server/default/deploy folder, if you use the "default" server config. * Edit the JBOSS_HOME/server/< servername>/deployers/ejb3.deployer/META-INF/ejb3-as-deployers-jboss-beans.xml and comment out (or remove) the following MC bean configuration: <bean name="EJB3MetadataOnDemandDeploymentDeployer" class="org.jboss.ejb3.deployers.EJB3MetadataOnDemandDeploymentDeployer"> <property name="profileService"><inject bean="jboss.profileservice:service=ProfileService"/></property>  <property name="deploymentRoot">${jboss.common.base.url}deploy</property>  <property name="singleDeployment">jboss-ejb3-timerservice-mk2.jar</property>  <property name="activateOnDemand">${jboss.as.deployment.ondemand:true}</property> </bean> h5.

I propose using Assignment Handlers to perform this task using the following steps: a) Find all members of the group to which this task can be assigned. b) Check the current count of tasks assigned to a user. c) For the user with the lowest workload, assign the current task. I am however unable to obtain the list of members forming the group. My Queries on above situation: 1) How can I derive members of a Group? 2) Is there any other method of achieving this than using Assignment handlers? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/563632#563632] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Tools] - SNMP monitoring of MBeans (attributes.xml in snmp-adaptor.sar)

by Evan Homan

Evan Homan [http://community.jboss.org/people/ephoman] created the discussion "SNMP monitoring of MBeans (attributes.xml in snmp-adaptor.sar)" To view the discussion, visit: http://community.jboss.org/message/563621#563621 -------------------------------------------------------------- I want to monitor some attributes of seveal MBeans that are running on my system: I have configured my attributes.xml unders snmp-adaptor.sar to include: <mbean name="jboss.ha:service=HASingletonDeployer"> <attribute name="MasterNode" oid=".1.2.3.4.1.22"/> <attribute name="PartitionName" oid=".1.2.3.4.1.23"/> <attribute name="TargetStopMethodArgument" oid=".1.2.3.4.1.24"/> <attribute name="TargetName" oid=".1.2.3.4.1.25"/> <attribute name="State" oid=".1.2.3.4.1.26"/> <attribute name="StateString" oid=".1.2.3.4.1.27"/> <attribute name="ClusterPartition" oid=".1.2.3.4.1.28"/> </mbean> But with my MIB browser I can only successfully do a get() on String or Int attributes. Boolean or objects will return an SNMP error. So, the adaptor is not even "publishing" the OID for those cases. For my above list, MasterNode, TargetName, and ClusterPartition fail on SNMP get(), the rest are successful. *Any workaround for this?* >From the JMX console for org.jboss.ha.singleton.HASingletonController: TargetName javax.management.ObjectName StateString java.lang.String MasterNode boolean ClusterPartition org.jboss.ha.framework.server.ClusterPartitionMBean TargetStartMethod java.lang.String TargetStartMethodArgument java.lang.String State int TargetStopMethodArgument java.lang.String PartitionName java.lang.String (among others) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/563621#563621] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Web Services] - JBossWS fetches the WSDL 4 times for every WS call

by Alan Feng

Alan Feng [http://community.jboss.org/people/alllle] created the discussion "JBossWS fetches the WSDL 4 times for every WS call" To view the discussion, visit: http://community.jboss.org/message/563620#563620 -------------------------------------------------------------- I generated the client JAX-WS stub code to consume a remote SOAP service. When invoking the service, I noticed JBossWS seems to make lots of HTTP GET calls to retrieve the WSDL files. What I did was calling getPort() to get the service object, then invoke the operation repeatedly on this service object. What I found out is: - For the first call: there are 4 HTTP GET to retrieve the same WSDL before the actual SOAP POST. - Each subsequent call: there is 1 HTTP GET to retrieve the same WSDL before the actual SOAP POST. These excessive HTTP GET for the same WSDL certainly seems less optimal. Performance is degraged 300% for the first call and 100% for each subsequent call. Does anyone know how to tune this behavior so it only retrieves the WSDL once per service object? Has this been reported before? BTW, I'm using JBossWS Native 3.1.1 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/563620#563620] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Tools] - What can we track with JBoss Tools usage reporting?

by Andre Dietisheim

Andre Dietisheim [http://community.jboss.org/people/adietish] modified the document: "What can we track with JBoss Tools usage reporting?" To view the document, visit: http://community.jboss.org/docs/DOC-15798 -------------------------------------------------------------- h1. Preface We maintain a Google Analytics account to track JBoss Tools usage. Google Analytics is designed to track web page usage but it might be adapted to track other applications. That's what we did for JBoss Tools and implemented an Eclipse plugin that shall help us to gather userfull informations about our users in an anonymous manner. h1. How do we track users? When a JBoss Tools user starts its eclipse he triggers a hit to *http:///tools/usage/action/wsstartup /tools/usage/action/wsstartup* in our Google Analytics Account*.* There are other urls that are tracked (for instance /pureTest)*,* but these are not triggered by JBoss Tools users** and they're not relevant to our use case though*.* http://community.jboss.org/servlet/JiveServlet/showImage/102-15798-9-6353... http://community.jboss.org/servlet/JiveServlet/downloadImage/102-15798-9-... || Url || *Event* || | * /tools/usage/action/wsstartup (http://tools/usage/action/wsstartup)* | A JBoss Tools user starts its Eclipse | | */pureTest* (http:///pureTest) | Test plugin JUnit tests are run | | */tools/usage.html* (https://www.google.com/analytics/reporting/content?id=35061163&pdr=201008...) | Users browse our usage page on jboss.org http://jboss.org/tools/usage.html | h1. *What are the user values we track?* Google Analytics is designed to track browsers and users browsing web sites. Our Eclipse plugin emulates a browser and reports values the way a browser would. Of course using JBoss Tools in Eclipse does not match the use case of browsing web pages at 100%. It's very close to it though. There are values that are unique to our use case (to track application usage) and are not present in browsers. We map those to values to settings Google Analytics tracks for browsers and misuse their original intent. || *Google Analytics Field* || Information we report || *Values* || Example || | *Keyword* | What are the *JBoss Tools components* that are installed? | * archives * as * birt * bpel * cdi * deltacloud * drools * esb * flow * freemarker * gwt * hibernatetools * jbpm * jmx * jsf * jst * labs * maven * modeshape * portlet * profiler * runtime * seam * smooks * struts * tptp * vpe * workingset * ws * xulrunner | http://community.jboss.org/servlet/JiveServlet/downloadImage/6331/keyword...

[JBoss Tools] - Friday Statistics with special thanks Brazil!

Max Andersen [http://community.jboss.org/people/max.andersen%40jboss.com] modified the blog post: "Friday Statistics with special thanks Brazil!" To view the blog post, visit: http://community.jboss.org/community/jbosstools/blog/2010/09/24/friday-st... -------------------------------------------------------------- We added usage tracking into our http://community.jboss.org/message/561160#561160 JBoss Tools 3.2 M2 release and since then it have been pouring in with pings from all over the world and we love every second of it. Nothing like it, seeing your hard work being used across the planet. Today we've passed 1.000 different cities and the number is ever increasing. http://community.jboss.org/servlet/JiveServlet/showImage/38-1971-9333/ga_... http://community.jboss.org/servlet/JiveServlet/downloadImage/38-1971-9333... The above screenshot is a snapshot of the current cities we have received pings from over the last week. Darker color and size of the circle indicates the % of visits. For now Brazil and especially the Sao Paolo region has the biggest crowd. Yesterday we had 2.500+ instances of JBoss Tools starting up within 24 hours and our total of unique Eclipse installs using M2 passed 18.000 this morning. Very happy to see that much pickup of our M2 release within just a week, I'm very postively surprised so many approved and enabled the tracking and growing every day. Many thanks for those who did and those who will in the future - it's much more fun than watching simple download counts and give some nice fun content for a Friday blog :) -------------------------------------------------------------- Comment by going to Community [http://community.jboss.org/community/jbosstools/blog/2010/09/24/friday-st...]
