Re: [JBoss-user] JBoss 3.2.2RC2 Classloading Fun

[Scott M Stark]

Ears have never been isolated by default. Wars have been until the change to 
allow the tomcat container to use the unified class loader as the web app class 
loader. Setting UseJBossWebLoader to false restores the previous behavior of a 
distinct child class loader per war. Use of the unified class loader at the web 
container level does allow for sharing of struts across web deployments for 
example. It also allows for aop integration down to the web container in 4.0.

So far, everything I've tried under JBoss 3.2.2RC2 works (with the

RE: [JBoss-user] Parallel thread performance: A JBoss client example

[Kevin Duffey]

I suppose I am after a few things. Initially my
thought was a standard simple test that will permit a
company to test it against several servers to see
which one fits the bill for performance, price, etc.
You mention a test suite that does this, I didn't even
think about that.

My second thought is a tool that like the big boys,
can simulate virtual users, run nodes on each "client"
machine to simulate them, and aggregate data, as well
as have nodes on the server side, maybe even the DB
side to monitor things like cpu utilization,
request/response timing, and so forth. All of that
data is aggregated to the central client where you
control various nodes, configure them, etc.

I know tools from Mercury Interactive and others can
do this, but at astronomical costs they are not
feasible to a small company. But that is more or less
what I am after.

RE: [JBoss-user] Parallel thread performance: A JBoss client example

[Jon Barnett]

Just my two bits worth again -

I guess fully built applications are fine for exercising the entire app
server or as much as you can make it exercise the entire app server, and
perhaps I focus on the micro-level a bit too much but:

The high level testing view doesn't tell you individual breaking points -
at what request rate does my stateless session bean container degrade in
response performance, at what request rate does my stateful session bean
container degrade in response performance, etc. What characteristics can I
expect for each of these in single and clustered mode? e.g. What is the
response curve?

With high level testing, you get an idea overall perhaps - but because
things will most likely break at different points, a specific application
may self-destruct before or after a general test application breaks.  The
natural bottlenecks in a general application may hide problems in an area
of concern because other circumstances prevent a particular sub-system
from reaching a critical state.

SpecJ2002 does provide you a framework for cluster testing - I think the
test results for a HP cluster just came out. All well and good in the
general testing category - but what if my application has a critical
reliance on JMS? How do I know when that will break? What if the
application server doesn't support it? How do I exclude that testing
category?

It depends on where you want to take your test suite and whether you want
to benchmark specifics or general operation.

Mine's a mechanic's view point. I'm not with JBoss Group - but the code is
open source. So I'd like the analysis tools to send 240V 3-phase through
some JBoss sub-system and determine the output response. If there's
roll-off when I vary the input, I'd like to know why so it can be fixed.
;) And obviously I'd want the controls to vary the input. At the moment,
I'm pretty much creating the tools as I need them since none come to hand.
ECperf doesn't have the granularity of control and ease of use to perform
any diagnostics on things when they break. It probably gives purchasers
the warm-fuzzies and I believe that is the sole intention of it. But other
than that, it has all the finesse of a chainsaw when trying to perform
microsurgery. :)

If your suite is intended for multiple app servers, using xDoclet would be
nice. SpecJ2002, at first glance, seems to have progressed from ECperf 1.1
in that the coding is neater but it still has those pre-built XML
deployment descriptors so it's still a roll your own in that department -
just a little painful. I've got to dig deeper yet.

Remember - none of this is meant as a criticism. I'm just interested in
seeing where you're going so I know whether we overlap or we don't in what
we are doing. :)

Re: [JBoss-user] Failover problem...

[Kevin Duffey]

Get 3.2.2RC2, try it with that one. A lot of
clustering issues have been fixed in the 3.2.2x
release as I understand it, or perhaps not a lot, but
the few there were. We saw problems with 3.2.1 that
worked in 3.2.2RC1, so give it a whirl.

[JBoss-user] Failover problem...

[Russell Chan]

Hi,

I'm trying to currently get a two node cluster and a client work only in
a failover setup.  I'm using jboss-3.2.1.
my jboss.xml file has entries such as:

  true
  
  TestEJBPartition
org.jboss.ha.framework.interfaces.FirstAvailable

org.jboss.ha.framework.interfaces.FirstAvailable
  
And, my client code has jndi.properties that look like:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming
java.naming.provider.url=172.23.254.12:20100,172.23.254.11:20100
(20100 is the HA-JNDI port for these two machines).



The behaviour that I'd like is for the client to use just the first host 
(172.23.254.12) until it fails, and then failover to host 2 
(172.23.254.11).  However, no matter what I try, the client seems to 
round-robin the calls.  I've read through the purchased clustering docs, 
and I'm failing to see something simple here.

The clustering DOES appear to work flawlessly, as I have stateful, 
stateless, and entity beans all in this partition, which work.  My 
problem is that I want fail-over really, not clustering per se.

Any pointers?

Thanks,
Russ Chan

First thanks for the offer of help, Bela. Being downunder, sometimes you

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.


I've been testing JavaGroups under load recently, so I'm primarily 
interested in that. So if we get to clustering or JMS/JavaGroups, I'd 
definitely be interested in tuning the JavaGroups -related parameters.

Yes, I see that know...

Would you expect the following to work correctly:

Context initCtx = new InitialContext();
DataSource ds = (DataSource)initCtx.lookup("java:MyDS");

Re: [JBoss-user] Clustering Problem

[Kevin Duffey]

Did you put it in node 2 when both were clean?
Re-deploying of apps in the /farm dir doesn't seem to
work in RC1. You may want to get the very latest RC2
that just came out two days or so ago. That may have
fixed it, but I haven't tried yet. Anywho, I also note
that the only thing that works with farming is if you
first deploy it (clean deploy), it propery farms. If
you delete it out of one node, it then properly
undeletes it out of other nodes. So, as of now, to
redeploy, first delete it, then add it again.
Shouldn't be this way, so hopefully RC2 fixes that
problem.

RE: [JBoss-user] JNDI lookup failure, ... not bound.

[Danny . Yates]

That's because your code looks up "java:comp/env/MyDS", not "java:/MyDS".

Subject: [JBoss-user] JNDI lookup failure, ... not bound.


Hi,

I am trying to access a MS Sql server DataSource. I have done the following:

1. Modified mssql-ds.xml to refer to my server.
2. Placed mssql-ds.xml in the server/default/deploy directory
3. Copied the SQL server jars to the server/default/lib directory

I get messages back from jboss saying the following:

[MyDS] Bound connection factory for resource adapter for 
ConnectionManager 'jboss.jca:service=LocalTxCM,name=MyDS to 
JNDI name 'java:/MyDS'

When I use JNDIView from the jmx-console I get the following:

MyDS (class: org.jboss.resource.adapter.jdbc.WrapperDataSource)

However when I try and use this data source with the following code I
get a NamingException - MyDS not bound:

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
DataSource ds = (DataSource)envCtx.lookup("MyDS"); <-- Exception here

Cheers

Rob Tomlin

Hi all,

Quick question. I’m deploying my app in an ear file.

The jsps are contained in a war in the ear.

If I want to change a jsp, currently I redeploy the ear.

I am wondering if the actual jsps are available, unpacked in

some directory where I could just change the jsp code on the

fly.

Thanks,

Antwort: [JBoss-user] AIX 4.3.3-03 build of 3.0.8 & 3.2.1 run error

[H . Baxmann]

I am happy with myself. Sometimes i may contriibute something to my own work by
myself:

the aprropriate VMM setting in AIX for the -Xms384m and -Xmx786m options is:

LDR_CNTRL_MAXDATA=0x5000

this should make the kernel able to allocate (4+1) x 256m, how i understand the
whole banana.

The first execptional case - class not found, because of wrong name - fade away
then, but the principal=null is a persistant (CMP ? ;-) one.

Would love to have the same (security?) config running on MacOSX, Win32 and AIX.

RE: [JBoss-user] Parallel thread performance: A JBoss client example

[Brian McSweeney]

Well if you want to learn xdoclet, the Xpetstore is the 
place to start. I recommend you download the source and 
get stuck in. It's quite simple.

The xpetstore is actually split up into two implementations 
of the same web-app. One uses ejbs with struts as a front-end, 
the other uses hibernate with webwork as a front-end.

I recommend you look at the ejb implementation (contained in the
xpetstore-ejb folder).

Xdoclet is used to auto-generate all the xml configuration files 
for you, and the reason the xpetstore can deploy on each of the 
server is that xdoclet "tags" for each application server are 
placed within the ejbs.

If you have any problems understanding any of it, give me a shout.
I'd love to see a basic app working with clustering too, and some 
performance stats.
Brian

Great idea. You know, first I don't know what the heck
this xdoclet is. I see it being used in JBoss and
other places, but it's one more darn thing I gotta
learn! Second, I am hoping that clustering works out
of the box, with very little changes to the server, to
support clustering. I know JBoss is thus far the
easiest to configure. I am hoping that Orion is
similar (still). I did it back in the early 1.x days,
so I am not sure how their 2.0 version clusters.
WebLogic, well, that's a pipe dream that I'll have
test on that, too much darn money, unless they have a
free trial version but even then I recall they charge
more for their clusterable version than they do for
single jvm version.

[Brian McSweeney]

Hi all,

 

Quick question. I’m deploying my app in an ear file. 

The jsps
are contained in a war in the ear. 

If I want to change a jsp, currently I redeploy the ear. 

I am wondering if the actual jsps are available, unpacked in 

some directory where I could just change the jsp code on the 

fly.

 

Thanks,

Brian

[JBoss-user] Help - Cipher (NoClassDefFoundError)

[Keene Hammond]

Hi,
I am using java 1.4.2 with the strong US encryption and jboss 3.2.1.
Why do I get  a "NoClassDefFoundError" error when using Cipher in my 
mbean on JBoss? I am able to compile and test this in a application but 
I get an exception when I try iit on JBoss.

Here is the offending code block:

Cipher cipher = null;
try {
   cipher = Cipher.getInstance("DES/ECB/PKCS5Padding");
} catch (NoClassDefFoundError e) {
   e.printStackTrace();
}
Here is the resulting stack trace:

[JBoss-user] Clustering Problem

[Nishant Aggarwal]

Hi All,
I am working on JBoss 3.2.2RC1 and trying out clustering!
I am running 2 different JBoss on different machines in clustering mode,ie,
the 2 JBoss servers are started as "run.sh -c all".
Now , I have a simple SLSB "Hello.jar" with true
specified
in jboss.xml file.

Now, I tested 2 cases:
1.I try to put the above jar in the directory (all/farm) of the server
started "first".The Hello.jar gets deployed in both the servers and I can
see it in
corresponding "all/farm" dirs.
2.I try to put the above jar in the directory (all/farm) of the server
started "second".The Hello.jar gets deployed "only" in ""second" server and
"first"
server doesn't have any clue!

Can you pls help me out?Is there concept of Master/Slave etc?
Thanks in advance,
Nish

Subject: [JBoss-user] memory leaks during redeployment


  In Jboss 3.2.1 I often encounter OutOfMemoryErrors on our jboss
installations. I realized that if no redeployments happen the JBoss instance
even being on heavy load works great forever. Once I begin to often redeploy
applications I finally get OutOfMemoryError no matter if I
specified -Xmx300m or -Xmx800m. Can anybody run a memory profiler on a
redeployment process? I tried to do it with OptimizeIt and I always get +1Mb
of heap after each redeployment. Most new objects are of type Object[] and
are referenced from WeakHashMaps (which is ok I guess), from inside some
classes of Xerces parser and many more. I cannot of course judge whether
these new references are caused by the leak or not.
  As far as I remember I had no such problem when I used Jboss 3.0.
  As always, I am ok to offer any help I can.

Re: [JBoss-user] CMR Problem in 3.2.2RC2

[Alexey Loubyansky]

Hello Gavin,

I am sorry, it works for me! I used your source files, MS SQL Server
2000 and your testSchema.sql.

Anyway, I have some remarks. You are using unknown pk with name id,
while there is a CMP field id. You should not do it.
If you want a "known" pk and use a pk generation command, then just
mark the pk field as @jboss.persistence auto-increment="true".

Thanks, you are correct. I must have changed the package definition when

RE: [JBoss-user] Parallel thread performance: A JBoss client example

[Brian McSweeney]

Hi Kevin,

This sounds like it would be a brilliant thing to do. 
As a suggestion, if you want it to run a standard app 
on multiple app servers as the test, it might be 
possible to use a current sourceforge project.

The xpetstore project deploys on JBoss, Orion 
and Weblogic by using xdoclet tags. 

Perhaps this app could be changed to handle clustering
rather than having to write an entire app from scratch?

Just a suggestion,

Brian

Subject: RE: [JBoss-user] Parallel thread performance: A JBoss client
example

For me, I want a comprehensive suite of tests to run.
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.

Sorry, I was unclear.

What I meant was to leave everything as it is now in respect of non-XML
files,
so the log4j and security deployers will continue to work. However, rather
than
making the file name of the XML files important, you could deploy them based
on
their DOCTYPE. You could employ a mechanism similar to JDBC where each
registered
driver (or XML sub-deployer) would be offered the file in turn. This way,
you
could even decide which sub-deployer to used based on content other than the
DOCTYPE.

Anyway, it was just a suggestion! :-)

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. A security configuration deployer may work off
of 
the legacy auth.conf file. You are suffering from an overdose of xml
exposure.

AW: [JBoss-user] Installing Jboss-3.2.1-Tomcat-4.1.24 as service using JNT

[Janardhan Burugupalli]

HI All,

Can any one please send me valid script fro installing
Jboss-3.2.1-Tomcat-4.1.24 as a service using JNT.exe. I am trying to
install it on an XP machine with Jdk1.4.1_03.

I am currently using this script to do it but it fails. but please excuse me
if it has been already discussed. I searched the fomrums but there are
instructions for using JavaService.exe.

set JAVA=%JAVA_HOME%\bin\java
set CP =%CP%;"%Java_Home%\jre\bin\server\jvm.dll"
set CP =%CP%;"%Java_Home%\lib\tools.jar"
if exist %JBOSS%\lib\crimson.jar set CP="%JBOSS%/lib/crimson.jar"
if exist %JBOSS%\lib\ext\xerces.jar set CP=%CP%;"%JBOSS%/lib/ext/xerces.jar"
if exist %JBOSS%\bin\run.jar set CP=%CP%;"%JBOSS%/bin/run.jar"

RE: [JBoss-user] Parallel thread performance: A JBoss client example

[Jon Barnett]

OK. I can see the focus on cluster rollover. ;)

We have conducted tests in a similar manner to queuing requests remotely.
You can create a stateless EJB to make remote and local calls to itself
(or other EJBs) as well as naming server lookups. If you look at our JBoss
performance paper you'll see the code, which is quite simple
http://www.amitysolutions.com.au/downloads/JBoss_code.pdf. So those kinds
of things are nice and easy to do - since such a bean operation could be
quite long running loop through and make 100,000 invocations, you could
stack it up and get quite a few running to see the internal performance -
if that is useful.  You probably don't want so much load that CPU
saturation deforms the response.

The problem for clustering will be to define a controlled test that is
repeatable and easily configured for load whilst avoiding any deformations
in the load generator. I think you will want to look at steady state
responses and various degrees of load. How does round-robin perform with
light, medium and heavy load? Versus other schemes?

The bean method (internal load) will also need to be thought through. If
it does a lot of processing, is this indicative of a real load - if an EJB
spends time retrieving from a database, this results in lighter CPU load
in the EJB container. If you introduce a database, how much influence will
the connection pool operation effect times. Still thinking on this. I
suspect as part of the tool set, you would need to build a JDBC loopback
plug with a dummy return and tuneable response?  This could be used to
advantage to see how the app server responds to a pileup of waiting EJBs.

I think some broad categories of tests need to be defined first and then
refined. It will give a point of reference for devising these torture
tests and how they would work.

So let me summarise to date:

Clustering
Response
- lookup?
- purely invocation?
- fixed computing load?
- fixed time load?

Aim: tabulate useful characteristics against single server versus
multiserver with different load balancing schemes

Issues: thread measurement, attaining steady state, load increment,
deformation in responses due to measurement hooks, calibration of test rig
and minimisation of non-linear effects in test rig (if they exist) or
normalisation of results to account for this - depends on whether this is
relative comparisons or standalone measurements.

JonB
