[JBoss Microcontainer Development] New message: "Profiling the kernel project"

by Kabir Khan

JBoss development, A new message was posted in the thread "Profiling the kernel project": http://community.jboss.org/message/525867#525867 Author : Kabir Khan Profile : http://community.jboss.org/people/kabir.khan@jboss.com Message: -------------------------------------------------------------- Running a very simple benchmark for deploying a 1000 beans of type Object with no dependencies or configured properties, i.e. protected List<BeanMetaData> setupContexts() { List<BeanMetaData> beans = new ArrayList<BeanMetaData>(iterations); for (int i = 0 ; i < iterations ; i++) { BeanMetaDataBuilder builder = BeanMetaDataBuilder.createBuilder("Bean" + i, Object.class.getName()); beans.add(builder.getBeanMetaData()); } return beans; } shows 85% of this time to be spent in the PreInstallAction. A similar test deploying 500 beans with dependencies in the wrong order (which we know from http://community.jboss.org/message/525809#525809 is very slow) shows 25% of the time spent in PreInstallAction. Most of the time spent in PreInstallAction comes down to adding to and reading from the BasicMetaDataRepository.retrievals map, which hits UnmodifiableScopeKey.equals lots of times (~2M times in the 1000 beans case): public boolean equals(Object object) { if (object == this) return true; if (object == null || object instanceof ScopeKey == false) return false; ScopeKey other = (ScopeKey) object; Scope[] otherArray = other.getArray(); return Arrays.equals(theScopes, otherArray); } I will dig into this tomorrow and see if this can be optimized somehow, and if it is a problem in MDR I'll open another thread for that. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525867#525867

[JBoss Messaging Development] New message: "How can I specify a message destination reference as my MDB destination?"

by Kevin Halk

JBoss development, A new message was posted in the thread "How can I specify a message destination reference as my MDB destination?": http://community.jboss.org/message/525828#525828 Author : Kevin Halk Profile : http://community.jboss.org/people/khalk Message: -------------------------------------------------------------- Hi there, Is there someway I can specify a message-destination-reference or message-destination-link as my MDB destination? It seems that I am required to specify a 'destination' in my MDB's activation-configuration, however this is a JNDI destination and I can't get it to pick up my message-destination-references. Also I'm not quite sure the point of specifying a message-destination-link if it's just going to listen on the destination anyway? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525828#525828

[JBoss Messaging Development] New message: "How can I use duplicate JNDI names for Queues?"

by Kevin Halk

JBoss development, A new message was posted in the thread "How can I use duplicate JNDI names for Queues?": http://community.jboss.org/message/525826#525826 Author : Kevin Halk Profile : http://community.jboss.org/people/khalk Message: -------------------------------------------------------------- Hi there, This may seem like a stupid question but is there any way to specify duplicate JNDI names for Queues? We require several separate EJBs to reference the same queue (A outputs to Q1, B reads Q1 etc..). I'd like to be able to have any number of these available at any time (i.e. both A and B might not necessarily be there). This means that either one could be responsible for creating Q1. I can specify the Queue to be created in A and B's deployment descriptors, however I get an error saying the JNDI name already exists when it tries to create the second time (obviously). I would like the Queue to be created if it does not already exist - is there any way to accomplish this without an error? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525826#525826

Anything you do other than the normal maven release tasks? Mvn release tasks are tricky. They mostly work, but when they don't, there is no way you can understand what's going wrong. In that case, DML has some instructions on the wiki. :-) But yeah, "mvn release:prepare" and "mvn release:preform" is all I do. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525793#525793

Take this example: Context A has a DependencyItem{iDependOn=B whenRequired=CONFIGURED dependentState=CONFIGURED} Context B has a DependencyItem{iDependOn=C whenRequired=CONFIGURED dependentState=INSTALLED} We install A and it hangs in INSTANTIATED We install B and it hangs in INSTANTIATED We then install C Old model: Outer loop iteration N: inner loop until START Find C, move it to INSTALLED break out since we incremented contexts next outer iteration: inner loop until INSTANTIATED: Find A, do nothing since B is not in CONFIGURED Find B, B has its dependencies resolved and gets moved to CONFIGURED break out since we incremented contexts next iteration: inner loop until INSTANTIATED: Find A, A has its dependencies resolved and gets moved to CONFIGURED break out since we incremented contexts next iteration: inner loop until CONFIGURED: Find B, B gets moved to CREATE (it is before A in the COWAS for the state) Find A, A gets moved to CREATE break out since we incremented contexts next iteration: inner loop until CREATE: Find B, B gets moved to START, break out Find A, A gets moved to START, break out break out since we incremented contexts next iteration: inner loop until START: Find B, B gets moved to INSTALLED, break out Find A, A gets moved to INSTALLED, break out break out since we incremented contexts New model: C goes through all the states until INSTALLED next outer iteration: inner loop until INSTANTIATED: Find A, A has its dependencies resolved and gets moved to CONFIGURED next inner loop CONFIGURED Find A, A gets moved to CREATE next inner loop CREATE Find A, A gets moved to START next inner loop START Find A, A gets moved to INSTALLED next outer iteration inner loop until INSTANTIATED: Find A, do nothing since B is not in CONFIGURED Find A, A has its dependencies resolved and gets moved to CONFIGURED next inner loop CONFIGURED Find A, A gets moved to CREATE next inner loop CREATE Find A, A gets moved to START next inner loop START Find A, A gets moved to INSTALLED I was talking about changing COWAS for contextsByState earlier, but this exercise has convinced me that it is needed due to the fact that its iterator will return contexts in the order they were added. So in both cases C enters CONFIGURED, CREATE, START and INSTALLED before B, and similarly B enters those states before A. This is as it should be at least from the old ServiceController training notes: if a context has a dependency then the context we depend on will be created by the time we are created, and the context we depend on will be started by the time we are started. The only way I can think of breaking this is if B had a DependencyItem{iDependOn=D whenRequired=CREATE dependentState=INSTALLED}, in which case B would hang in CONFIGURED case until D is installed, meaning A would enter CREATE, START, INSTALLED before B, but that is true in both models. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525792#525792

Sure, with VFS there is np. I/we need to check with Adrian if he has some open (aka not commited) CL stuff. And I'll check my deployers and mc-scan work, if it breaks with VFS3. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525790#525790
