Re: [JBoss-user] ApplicationDeadlockException on read-onlymethods
Thanks Julien - I think that explains it. So if another TX has already locked the bean, then it's not possible to call the read-only method until the first TX completes? That might well explain what I'm seeing. Is there a way to have some methods that don't lock the bean at all? Kind of like optimistic locking, but applied per-method (so that write methods still lock the bean, but a read method can execute even against a locked bean?) ta Chris [EMAIL PROTECTED] 07/23/03 07:24pm with QueuedPessimisticEJBLock, read-only shorten the duration of the lock, it does not remove it. it locks the bean for the duration of the call instead of the duration of the transaction. julien CM As I understand it, methods marked as read-only on an entity bean shouldn't try and lock the bean when they are called. So, if I have two instances of an entity bean (same bean class, different CM PK), they can call read-only methods on each other at the same time.

Re: [JBoss-user] Managed Connection Pool running out of connections
Thanks, yes I figured it out in the end, and actually I've removed transactions altogether for the beans involved because everything is read-only and there's no worries about inconsistent state. I think there's probably a bug in the Connection Manager, so that when WrapperDataSource.getConnection() is being called the exception is thrown but a connection is still reserved from the pool and never gets reclaimed (including if you flush the pool). Looking at the code (and I'm still trying to get my head around it), it looks like TxConnectionEventListener.enlist() is throwing a SystemException because it can't enlist the XAResource with the Tranaction which is rolled back. By this point a managed connection has been got (in BaseConnectionManager2.allocateConnection()), and there doesn't appear to be anything that returns it when enlist throws an error. -Andrew Scott M Stark wrote: Alright, so the issue is that a stateful session is being accessed after it has been thrown out due to its inactivity exceeding its max age value. Either you need to increase the period over which passivated sessions are kept or isolate the access of the stateful session from the encompassing transaction using a RequiresNew tx attribute to prevent the failure from affecting the encompassing tx. --- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.

Re: AW: AW: [JBoss-user] problems with mysql and transactions
Hello Sven, this your sequence: client - a.init() required - a.initMessage() required - message.create() required - sequenceService.getNextSequenceNumber() required - sequence.getValueAfterIncrementingBy RequiresNew after entity bean is created, it is locked by the tx in which it was created. The lock will be released when the tx commits or rolls back. Later in sequence, sequence.getValueAfterIncrementingBy starts a new tx and tries to access the created entity which is locked and it waits for the lock to be released. As you see, it is just a deadlock. alex Thursday, July 24, 2003, 1:51:26 PM, Sven Scheil wrote: SS hi scott, SS we are suing mysql-connector 3.0.8. but i've created a test scenario where SS this error occurs with cloudscape and mysql the same way.

[JBoss-user] Parallel thread performance: A JBoss client example
As some people have asked about more complex loads, we provide an example that first lead us to investigate the issue of performance. With a multi-CPU system at our disposal, we should be able to generate a lookup load and a remote invocation load using multiple threads and measure throughput. Unfortunately, as threads increased so did the thread task durations. We finally returned to this and document it here. We hope it will satisfy those who wish to know. The lookup and the invocation response characteristics confirm our initial test findings where object creation was included in load operation. http://www.amitysolutions.com.au/documents/Threads-technote.pdf Again, we stress that this is not indicative of any operation in a production environment. We are also testing raw parallel throughput, without any explicit synchronisation effects so this needs to be taken into consideration as well.

[JBoss-user] URGENT ASSISTANCE
From: Mrs Theodora Banksway PLEASE ENDEAVOUR TO USE IT FOR THE CHILDREN OF GOD. I am the above named person from Kuwait. I am married to Mr. Paul Banksway who worked with Kuwait embassy in Ivory Coast for nine years before he died in the year 2001. We were married for eleven years without a child. He died after a brief illness that lasted for only four days. Before his death we were both born again Christians.When my late husband was alive he deposited the sum of$5.6Million (Five Million six hundred thousand U.S. Dollars) with one Global Security Company in Spain. Presently, this money is still with the Security Company. Recently, my Doctor told me that I would not last for the next three months due to cancer problem. Though what disturbs me most is my stroke. Having known my condition I decided to donate this fund to church or better still a christian individual that will utilize this money the way I am going to instruct here in. I want a church that will use this fund to fund churches, orphanages,Research centers and widows propagating the word of God and to ensure that the house of God is maintained. The Bible made us to understand that Blessed is the hand that giveth. I took this decision because I dont have any child that will inherit this money and my husband relatives are not Christians and I dont want my husbands hard earned money to be misused by unbelievers. I dont want a situation where this money will be used in an ungodly manner. Hence the reason for taking this bold decision. I am not afraid of death hence I know where I am going. I know that I am going to be in the bossom of the Lord. Exodus 14 VS 14 says that the lord will fight my case and I shall hold my peace. I dont need any telephone communication in this regard because of my health because of the presence of my husbands relatives around me always. I dont want them to know about this development. With God all things are possible. As soon as I receive your reply I shall give you the contact of the Global Security Company in Spain. I will also issue you a letter of authority that will empower you as the new beneficiary of this fund. I want you and the church to always pray for me because the lord is my shephard. My happiness is that I lived a life of a worthy Christian. Whoever that wants to serve the Lord must serve him in spirit and truth. Please always be prayerful all through your life. Any delay in your reply will give me room in sourcing for a church or christian individual for this same purpose. Please assure me that you will act accordingly as I stated herein. Hoping to hearing from you. Reply me at my alternative mail box: [EMAIL PROTECTED] Remain blessed in the name of the Lord.

Re: [JBoss-user] Parallel thread performance: A JBoss client example
Very good stuff! Question, how can we proceed in testing a clustered setup along similar lines as you have done here? I am curious to see how effective scaling a given application is. From a single node, to two nodes, to three nodes, then on to a second partition and so forth. It would be extremely helpfull if the JBoss site posted some information regarding use of JBoss in a true enterprise situation, where clustering, scaling and so forth is examined in detail. I think that would go a long way to credit JBoss as being enterprise worthy, even though it already is well on its way to that credibality. A fellow JBoss enthusiast and I are looking at developing a simple J2EE application and some testing procedures to test as I have described above. It is more of a generic J2EE app that should allow testing of clustering in any J2EE app server, but in general we are targeting JBoss. My initial test idea was testing single client to one ejb bean (stateless) 1000's of requests, measuring the length between request/response, maybe measuring timing on the server side, and so forth. There would be a client swing app that runs these tests, grabs the data, etc. On the J2EE app, it would send data back in some form to offer at least the measurement of tasks. This wouldn't easily translate into any other applications performance, but it might give the industry using Jboss some sort of idea how well it can cluster, scale, etc. What do you think? Have you already done this? --- Jon Barnett [EMAIL PROTECTED] wrote: As some people have asked about more complex loads, we provide an example that first lead us to investigate the issue of performance. With a multi-CPU system at our disposal, we should be able to generate a lookup load and a remote invocation load using multiple threads and measure throughput. Unfortunately, as threads increased so did the thread task durations. We finally returned to this and document it here. We hope it will satisfy those who wish to know. The lookup and the invocation response characteristics confirm our initial test findings where object creation was included in load operation. http://www.amitysolutions.com.au/documents/Threads-technote.pdf Again, we stress that this is not indicative of any operation in a production environment. We are also testing raw parallel throughput, without any explicit synchronisation effects so this needs to be taken into consideration as well.

Re: [JBoss-user] Parallel thread performance: A JBoss client example
Kevin, Jon, when you get to that point, knock on my door. There are huge perf gains to be realized by using protocol stack specs that are optimally tuned to the task at hand. E.g. for large sustained message tests, you would *not* fare well with the default properties for JavaGroups. Cheers, Kevin Duffey wrote: Very good stuff!

MR Hi Gurus,
MR Objective
MR
MR Since my web server and all other services start prior to JBoss, I want
to
MR provide a notification to user through the web UI, saying that the
services
MR are starting, if the user tries to access the application before the
App.
MR server is up.
MR To Know
MR ===
MR What I wanted to know is, is there any API exposed from which we can
know
MR about the JBoss server startup. So I can access this API at regular
MR intervals from UI, and re-direct the URL once the JBoss start has
completed
MR successfully.
MR Thanks

Re: [JBoss-user] Database JNDI Name Not Found
That is simply a restriction of the current architecture. If deployers want to base recognition off of the doctype they may do so. However, it is to restrictive. The JARDeployer in fact works by NOT finding an xml file that could be considered a deployment descriptor. A log4j configuration deployer may work off a log4j.properties file.

[JBoss-user] CMR Problem in 3.2.2RC2
Hi,
I posted this to the group a couple of weeks ago when trying to get
3.2.2RC1 working. Alex had a look at it and figured it was fixed for RC2. As
RC2 was only a couple of weeks away I decided it'd be easier for me to wait
for RC2 than build it, my mistake, I've just grabbed RC2 - it's still there.
(I'll log a bug this time).

Subject: CMR Problem in 3.2.2?
Hi,
I posted yesterday and last week about a problem I was
having with CMR when I upgraded from 3.2.0 to 3.2.2. I've
done more investigation and I don't think my previous mails
were entirely accurate (or very clear) so let me start over.
The Problem:
I'm experiencing NPE in our app because the CMR
relationships are (apparently) not being created. This didn't
occur with our app in 3.2.0.
I have a sample case which I believe is representitive of
the problem I'm seeing in our app. The beans are Foo Bar
(sorry about the naming). The relationship is N-Foo-1-Bar.
The relation is being set in post create:
public abstract class FooEJB extends AbstractEntityBean {
...
public void ejbPostCreate(BarLocal bar, String fooValue)
throws CreateException {
sLog.debug(ejbPostCreate( + getId() + ));
this.setBar(bar);
}
...
}
And I have a test session which does the following:
...
BarLocal bar = createBar(This is a bar);
FooLocal foo = createFoo(bar, This is a foo);
sLog.info();
sLog.info(Bar id through foo: + foo.getBar().getId());
sLog.info(Bar id through bars foos: );
Collection foos = bar.getFoos();
sLog.info(Number of foos associated with bar:
+ foos.size());
Iterator fooIter = bar.getFoos().iterator();
while (fooIter.hasNext()) {
FooLocal tmpFoo = (FooLocal) fooIter.next();
sLog.info(Foo id: + tmpFoo.getId());
sLog.info(Bar id: + tmpFoo.getBar().getId());
}
sLog.info();
...
I'd expect the output of this test case to be:
18:58:38,875 INFO [FooBarSessionEJB]
18:58:38,890 INFO [FooBarSessionEJB] Bar id through foo: 1011
18:58:38,890 INFO [FooBarSessionEJB] Bar id through bars foos:
18:58:38,890 INFO [FooBarSessionEJB] Number of foos
associated with bar: 1
18:58:38,906 INFO [FooBarSessionEJB] Foo id: 1017
18:58:38,906 INFO [FooBarSessionEJB] Bar id: 1011
18:58:38,906 INFO [FooBarSessionEJB]
What I'm actually seeing is:
18:58:38,875 INFO [FooBarSessionEJB]
18:58:38,890 INFO [FooBarSessionEJB] Bar id through foo: 1011
18:58:38,890 INFO [FooBarSessionEJB] Bar id through bars foos:
18:58:38,890 INFO [FooBarSessionEJB] Number of foos
associated with bar: 0
18:58:38,906 INFO [FooBarSessionEJB]
***
If I add a finder call after the beans are created (which
forces the beans to be synchronized to the database) then I
get the results I expect. This makes me think that there's a
problem with the caching - the bar returned by the
create() call is not the same Bar instance as returned by
foo.getBar(). Which means that I have 2 instances of the same
bean within the same transaction which have different state -
seems like a bug to me, I'd have expected the foo.getBar()
call to return the same bar as was passed to the create() call.
I've attached the source. For the sample, let me know what you think,
thanks,
gavin

RE: [JBoss-user] Parallel thread performance: A JBoss client example
Kevin, Bela; First thanks for the offer of help, Bela. Being downunder, sometimes you feel a bit isolated - where is the Australian JBoss user community? ;) Anyway, I'm not sure where things are headed with testing but help is always appreciated. The testing question is a big one. It depends on what you are trying to achieve. If it is steady state operation, I would say that a cluster of JMeter clients can generate a reasonable load that you can tune. Based on the threading issues discovered here, I wouldn't have the client on the same machine under test if you are using Linux. There would be too many questions on client load versus server load. One of the nice things about hindsight is that the free-running client load testing told us something about what to expect when looking at the JBoss-client results. So for completeness, you would probably want a calibration sample of your test rig with the minimal JBoss interaction as we had done in the JBoss-client test. Then you can look at responsiveness under a certain load characteristic - for example 50 requests per second what is the average response time, what are the maxima and minima. Dial it up and check again. As long as the test rig can generate the requested load level (calibration will tell you when things might start to deform in the test generator), you will be reasonably certain about the performance of the system under test. If you are just stress testing the system to check raw throughput, then you can adopt the load and transmit operation we employed for this test. Except we were hoping for less parallel thread coupling effects. You were able to see from these results for example, that the name server and the EJB invocation were not unduly stressed with an 8 client-load continually making requests for an extended period (for the IBM SDK). The predominant response characteristic was that of the client system. We haven't looked at your particular idea but any measurement is better than no measurement at all. Besides, I think there needs to be something beyond the ECperf-type tests. They tell you how the big picture is supposed to work but don't help you work out where things fall apart. I would suggest that measurement data if possible, is not transmitted from the server during testing (unless you can guarantee its affect would be minimal to the testing results). I think the best thing is to flesh out what you want to come away with from the testing. I'm sure there are others here in the forum with good test and measurement experience who can contribute to the cause. An example of things to think about - do you want to test solely EJB performance? Do you want to couple it with a DB? How do you separate DB from Server issues? Some nice things to see on the cluster testing is the impact of the load distribution algorithm. Is there a step-over point? How would you test it? I think it is a matter of asking what you want to observe and then determining a test scenario that would allow you to see it. Now if some Australian company can donate a Sun multi-CPU Blade server for testing, I could check the performance of the Java thread implementation on a Sun system. :) Anyway, that's a starter for discussions. I know I haven't directly answered your question about how to proceed but I am just trying to get a feeling about the exact things you want to measure.

Because we expect that if you want an xml fragment you define your attribute type to be org.w3c.dom.Element in which case you get the attribute content child element.

I want to measure the response times between a client and the server, the time a server gets a request until the time it goes back, the number of threads running, the number of simultaneous requests going at one time. I want to see reports on the scaling capabilities of JBoss. One node, two nodes with round robin, two nodes with first available, three nodes, two partitions, etc. I want to see how close to linear scaling occurs when adding more nodes, more partitions, etc. I want to see for myself that my idea of a good cluster architecture is indeed good, or maybe another way is better. I want to do these tests for stateless ejb and statefull ejb, and while my specific needs to not entail a web application, I would also like to see the performance with things like a client sending web service requests, which in turn hit the ejb server, and so forth. Ideally, it would be very strong for JBoss to have these and many more test results available. Realistically, we both know that no one app is going to certify JBoss, every app will no doubt have different characteristics, and thus results. But it would be great to provide a client/j2ee type of tool that can be used/deployed in any J2ee server to see the various results. Running Orion, Jonas, JBoss and Primatti side by side (one at a time of course) on the same hardware with the same test data and same setup would be very nice, to see which one supports better load, better clustering, better scaling, and so forth. These are the types of results I am after. --- Jon Barnett [EMAIL PROTECTED] wrote: Kevin, Bela; First thanks for the offer of help, Bela. Being downunder, sometimes you feel a bit isolated - where is the Australian JBoss user community? ;) Anyway, I'm not sure where things are headed with testing but help is always appreciated. The testing question is a big one. It depends on what you are trying to achieve. If it is steady state operation, I would say that a cluster of JMeter clients can generate a reasonable load that you can tune. Based on the threading issues discovered here, I wouldn't have the client on the same machine under test if you are using Linux. There would be too many questions on client load versus server load. One of the nice things about hindsight is that the free-running client load testing told us something about what to expect when looking at the JBoss-client results. So for completeness, you would probably want a calibration sample of your test rig with the minimal JBoss interaction as we had done in the JBoss-client test. Then you can look at responsiveness under a certain load characteristic - for example 50 requests per second what is the average response time, what are the maxima and minima. Dial it up and check again. As long as the test rig can generate the requested load level (calibration will tell you when things might start to deform in the test generator), you will be reasonably certain about the performance of the system under test. If you are just stress testing the system to check raw throughput, then you can adopt the load and transmit operation we employed for this test. Except we were hoping for less parallel thread coupling effects. You were able to see from these results for example, that the name server and the EJB invocation were not unduly stressed with an 8 client-load continually making requests for an extended period (for the IBM SDK). The predominant response characteristic was that of the client system. We haven't looked at your particular idea but any measurement is better than no measurement at all. Besides, I think there needs to be something beyond the ECperf-type tests. They tell you how the big picture is supposed to work but don't help you work out where things fall apart. I would suggest that measurement data if possible, is not transmitted from the server during testing (unless you can guarantee its affect would be minimal to the testing results). I think the best thing is to flesh out what you want to come away with from the testing. I'm sure there are others here in the forum with good test and measurement experience who can contribute to the cause. An example of things to think about - do you want to test solely EJB performance? Do you want to couple it with a DB? How do you separate DB from Server issues? Some nice things to see on the cluster testing is the impact of the load distribution algorithm. Is there a step-over point? How would you test it? I think it is a matter of asking what you want to observe and then determining a test scenario that would allow you to see it. Now if some Australian company can donate a Sun multi-CPU Blade server for testing, I could check the performance of the Java thread implementation on a Sun system. :) Anyway, that's a starter for discussions. I know I haven't directly answered
