[JBoss-user] Benchmark results JBoss/BEA Async Performance
Hi people, here are results for the messaging benchmarks, for BEA and JBoss. First, a little description of the scenario. -- -- We decided for this simple scenario to benchmark : PostingClient posts to Topic1. MDB1 (a message driven EJB) is listening on topic1, gets the message, puts its time of receipt in the message, and sends it to topic2. MDB2 (a message driven EJB) is listening on topic2, gets the message, puts its time of receipt in the message, and sends it to topic3. MDB3 (a message driven EJB) is listening on topic2, gets the message, puts its time of receipt in the message, and sends it to topic4. MDB4 (a message driven EJB) is listening on topic2, gets the message, puts its time of receipt in the message, and sends it to topic1. and when the message is posted to topic1, MDB1 regets the message. There is another listener on topic1 -- MonitoringClient. MonitoringClient gets the messages arriving there, and reports the times the message took between the 4 MDBs. Summary : the messages sent into the EJB Server remain in there, and make loops from MDB1 to MDB4 and back again, endlessly. Hardware : Pentium II, 400 Mhz, 256 Megs of RAM. OS : Windows NT4 VM : Sun 1.3 -- - --- Benchmark Testing Series : Weblogic Benchmarks: VM : 64MB heapsize. Configurations : 1) max-beans-in-free-pool : 50initial-beans-in-free-pool : 6 (in the entries in weblogic-ejb-jar.xml, for each of the 4 message beans) 2) max-beans-in-free-pool : 500initial-beans-in-free-pool : 62 3) max-beans-in-free-pool : 2000 initial-beans-in-free-pool : 250 for each configuration we tested (with 1 KB messagesize): 50 msgs, 500 msgs, 5000msgs, and infinite (until server crash - maximum time waiting for crash 30 minutess) On JBoss : VM: 64MB heapsize. Configurations: (in jboss.xml) 1) container-invoker : maximumsize 50,maxmessages 1 - container-pool: maximumsize 50 minimumsize 6 2) container-invoker : maximumsize 500,maxmessages 1 - container-pool: maximumsize 500 minimumsize 62 3) the maximum jboss could handle even with 128mb ram for the heapsize of the VM was : container-invoker : maximumsize 500,maxmessages 1 - container-pool: maximumsize 500 minimumsize 100 for each configuration we tested (with 1 KB messagesize): 50 msgs, 500 msgs, 5000msgs, and infinite (until server crash - maximum time waiting for crash 30 minutes) -- -- - Results for Weblogic : this server is very fast and stable. With 5000 Messages, we had a crash at configuration 1, at 1800 Messages sent. With configuration 2, it crashed at 3300, and with configuration 3 we had a crash as early as with 500 messages - but that was due to the low heapsize of the VM. When we raised the heapsize to 128Megs, the server ran good with 1 messages. Sending times : we mesaured the times needed for a message to be sent between to consecutive MDBs - for weblogic it was all around 0,1 secs. At 1 messages, average sending time was 1,4 seconds. For 5000 messages, even with config 3, we had 0,8 seconds. All other results were very acceptable, average times of 0.01 to 0.2. If you need any more details, contact me. JBoss : config 3,2 : 3 seconds average with 50 messages. Well, to be very honest : perhaps I m doing something fundamentally wrong, and I dont know exactly what strategy JBoss is pursuing in its kind of message delivery, but JBoss crashed at every config with 500 messages. Average sending times at 50 messages were 3 seconds, regardless of the configuration used, the parameters showed little or no effect. I know that these parameters should tune throughput, I know, and I know that with 4 topics and 4 MDBs, we are not simulating a true asynchrnously designed application, meaning : with asynchronous components only. But regardless of the throughput, no one wants to wait 12 seconds for a response. Even with 30 messages in the system, the average was 2 seconds, meaning 8 seconds in total to wait for a response : and this with only 4 asynchronous components. At 10 messages, we got average times of 0,7 seconds - meaning a response time of 3 seconds in total, which could be acceptable. It is also strange that weblogic showed significant CPU usage when increasing the JMS load, while JBoss stayed very happy with around 10%, not caring about any optimization in speed, it seems. Have we forgotten any parameters to SPEED up sending times, message delivery, or MDB invocation for JBoss ? I am really wondering. For precise details, contact me.

Re: [JBoss-user] strange error
Once I got following message and now it chases me: [Container factory] org.jboss.ejb.DeploymentException: expected only one enterprise-beans tag It's probably just not a very specific error message. One of your descriptors is probably misformed somehow, possibly in a way that confuses the parser and causes it to not see the enterprise-beans tag. Check this and post both descriptors if you still don't see what's wrong. You are right, I found already the reason too - there were two enterprise-beans in jboss.jcml The strange picture appeared because error was signalled only when one of beans mentioned in that tags, was deployed. That forced me to seek error in beans and their descriptors, not in jBoss configuration.

Both the JBoss and Jetty websites claim that both products run in the same VM. This allows servlets to access EJBs without going to the network layer, however I read this statement the 3rd party page and am confused: -- Jetty's xml file will not be optimized! Contexts setup with the jetty.xml file will be given their own classloaders which are not shared with JBoss, thus networks overhead will still incurred for EJB calls. http://www.jboss.org/business/jboss-jetty.html, how-to package and deploy section. -- Could someone explain this to me? Beau, Yes - this does look a little confusing. I'll try to explain it simply. As I understand it (and I'm no expert!): In order for a Servlet to talk direct, intravm to an EJB, both Servlet and EJB must be loaded with the same ClassLoader. This is achieved in JBoss by the J2EEDeployer. This takes an EAR file, splits it and passes the EJB jar to the EJB container with a ClassLoader and then the WAR to Jetty with the same ClassLoader. Deployment through the J2EEDeployer is either hot-deploy - you drop you EAR into the deploy directory, or via JMX - you send a request containing the URL of the EAR direct to the J2EEDeployer. Using Jetty's xml config file is neither of these, and has no way to coordinate ClassLoaders with target EJBs, since they are not loaded from the same place. In conclusion: Jetty supports optimised calls to EJBs (although there may be a bug in this as we speak!), but you must deploy through the J2EEDeployer to make use of this. I hope that is clear - I should probably put it i the doc. Jules thanks, -b __ Do You Yahoo!? Yahoo! Auctions - buy the things you want at great prices http://auctions.yahoo.com/ Your use of Yahoo!

Re: [JBoss-user] strange error - problem solved
Thanks to everybody for help and attention. Just for others, stepping on the same rake :-) It is clear now. The reason was _not_ in deployment descripttors but in conf/standartjaws.xml. This file may have those tags too. And I mistakely put a block of text with that section into this file. But XML parser ignores this error up to moment the bean mentioned in this section is deployed. And there was no file name in that message. Conclusion: if you have an error in descriptors but descriptors are OK - look at conf files. I got a few of those errors as well when I was attempting to deploy. Check your deployment descriptors closely. I typically made the following errors multiple times before figuring out what was going on: 1. Having a different copy of the deployment descriptors in my classpath. 2. Having the case differ between matching XML tags. You could always post your XML files if nothing seems obvious. -Dave -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mikhail Akopov Sent: Friday, May 25, 2001 5:28 PM To: [EMAIL PROTECTED] Subject: [JBoss-user] strange error Once I got following message and now it chases me: [Container factory] org.jboss.ejb.DeploymentException: expected only one enterprise-beans tag Sure - there is exactly one enterprise-beans tag.

Re: [JBoss-user] CMP database updates
The behavior you're seeing is 'normal' but fixable. Consider that the container can't actually tell if any of the bean's state has changed or not. Therefore, it errs on the side of caution and always persists the bean state. Actually, in BMP you'll notice that ejbStore always gets called as well. The solution to your problem is to implement a method 'boolean isModified()' that returns true if and only if the bean's state has been modified in the current transaction. You also want to create a jaws.xml file for your bean and turn the 'tuned-updates' flag on (if your patterns of modification are consistent - if not, this might just interfere with the database's caching of query plans). You probably also want 'has-pk-constraint' on when you initially deploy your bean, if you're allowing JAWS to create the table for you. See the documentation online at www.jboss.org for more details. -danch Chris DeGreef wrote: I am quite new to CMP. I am wondering why the database is being updated so often.

Re: [JBoss-user] :-) Tomcat sends CPU 100% ?!
Just throwin' this in: standalone Tomcat 3.x does this thing where it will always add a context root according to the war name; but if a Context is added in it's config/server.xml, it will add that too. They're trying to be helpful but in the end it's just confusing (sort of like when driving, giving up the right of way to be nice just ends up confusing everyone else on the road and makes the situation unsafe). According the the J2EE spec, a context name is assigned to a web application in the EAR's application.xml file, and has NOTHING to do with the name of the war file.

One test program is another Session Bean and one is a client application invoked via the command line (JBoss version 2.2 under Linux.)

Thetest consists of locating the Home for both the Entity and Session Beans, creating an instance of each type andinvoking methods on each newly created bean. One of the methods on the Session Bean I am testing takes as an argument the Entity Bean's remote object. This method, along with other methods which take simple types, work fine in the Test Session Bean.
