my biased perspective, Borland OptimizeIt is better than JProbe.
 
the last time I tried to use JProbe to profile Tomcat 4 it was ungodly slow. it's 
probably improved since then.

Hi,
They're both decent.  I like OptimizeIt better than both of them,
though.  It's a personal preference as the feature lists are nearly
identical.

JK2 still broken even in new version 2.0.4 with upload Stream ended unexpectedly error

2004-05-13 Thread Allistair Crossley

Well, since using 2.0.4 this error has been unheard of until today. A user has been 
trying to upload a document and tried 4 times and constantly got the Stream ended 
unexpectedly error from JK2 connector. The document is Word and 140K. I have tested 
with other users trying to upload this item and there has not been a problem, it seems 
restricted to this particular user!?

Does this ring any bells for anyone?

I honestly couldn't tell you. You'll have to look at the specs of OptimizeIt.
 
I normally test and profile everything on my laptop, which has 1gb of ram. I wouldn't

Ant deploy and context.xml

2004-05-13 Thread Rich Garabedian

I'm trying to use the ant autodeploy feature with a context.xml fragment in
the MET-INF directory. Mailing lists and all the documentation I've read
show this to be a no-brainer. I'm sure I'm being ignorant of something
incredibly obvious, but I just can't see it.

 

I'm using the basic build.xml  file from the Tomcat site.

I'm using Tomcat version 5.0.16

 

In the source directory I have

 

Build

Dist

Docs

Src

Web

 

Under web I have

 

META-INF

Templates

WEB-INF

 

In META-INF I have a context.xml fragment (contents included below).

 

When I do a build, I see that the META-INF directory and the context.xml
file gets copied the build directory. But when I do an ant deploy, it does
create an xml file in the Catalina conf directory (name of the file when
copied is the name of the web app, not context.xml). However, the contents
of the this file do not contain the specific configuration information I put
in context.xml.

 

 In summary, it does not appear as though the deploy task is using my
context.xml file when it does the install/deploy.

 

Ideas?

 

Many thanks in advance ..

If you're looking for a full restart, there are several ways (in varying
levels of hackishness).

Once you've figured out the trigger (described below), it's a matter of
having that call:
{tomcat script} stop ; {tomcat script} start


Triggers:

1 changes in a file: under Linux, you could use FAM to monitor a file
  (say, server.xml).  Under OSs that don't support FAM you'd have to do
  a periodic poll(), which may cause problems if there are many other
  processes poll()ing for files.

2 Tomcat request: under Linux/Unix, a servlet/JSP could fire a
  System.exec() that calls an at job.  That would put the call
  to the script outside of the current process.
  (Not sure how calls to System.exec() are prohibited by the default
  security manager.)

3 Without the at job, the container could create/update a specified
  file watched by the FAM/poll() app...

etc, etc.

If anyone's interested in #1, I'd be happy to drive it.  I've been
experimenting with FAM lately, and could probably whip up something that
supports non-FAM OSs, too...  If you wanted to stick with Java (make it
cross-platform) that should be fairly straightforward, as well.

If you're looking to reload the *app* on file change, that's probably a
matter of having the trigger kick a JMX action.  -but I've reached total
stream-of-consciousness here so I'll stop rambling... ;)

RE: Tomcat reboot runtime

2004-05-13 Thread Adam Buglass

Hi,

I'm not looking at highly specific tomcat code, that's way more
complicated than I'm thinking about.

I also don't see the need to faff about with shutdown - wait - startup. 

I was thinking (at a rather simplistic level) of having a restart script
which can be called from a JSP / Java class. I'm sure a Java program
could be written to call the shell script.

Alternatively you could try and exploit the kill -HUP command.
Probably the best way of doing this would be to setup tomcat to create a
pid file on startup a la Apache.

I will apologise now for not just going ahead and attempting to set this
up of my own accord on my system. I have no Internet access at home (in
fact I only just have a PC!) and work is far to hectic at this time for
non-essential messing about (a great shame!) :-(

RE: problem with isapi redirector

2004-05-13 Thread Srinivas Kotapally

Lohan

I am having the same problem!!  I am using Windows 2003 Server, IIS 6 and
isapi_redirector2.dll.  The site is accessible through port 8080 but in that
case I guess we are accessing Tomcat directly.

Guys,

I have checked all my settings... and I have everything set-up as directed.
But to no avail.  I guess would need to go to a lower version of the
isapi_redirector.dll (1.2.5 or even lower maybe!!).  There is no site that
says which redirector works with which version of IIS!?  I guess I would
need to go through the painful way to hit and trial!!

Any help would be greatly appreciated.

Cheers

Srini

Hi All,

I got a problem getting the examples to show.

When i copy a jsp file into my webroot directory of iis and i open it, it
displays fine.
But when i try to access the localhost/examples/jsp/index.html page it just
gives me a page not found error.

I reconfigured tomcat and iis about 10 times now, with different setup
guides and i get the same result everytime.

Must i publish the examples folder under the default website in iis, or is
the uriworkermap.properties file suppose to go and fetch
it from the webapp folder?

Please help,

Thanks,

Lohan

Are you sure this isn't related to heavy garbage collection in the JVM?

jvmstat has some good tools to monitor memory usage an garbage

the whole engine practically stopped for a few minutes and the load

connecting to the server and waited for the response for a long time.
When I checked the load on the box it was 1-2 (normally it's 0.5), but
didn't notice any processes hogging the CPU with 'top'. I already
fixed all DB connection leaks I had so that can't be the issue here.
Traffic peaks can't be it either, I have constant traffic.

I know that this isn't a precise description of the error I'm

CGIServlet problem

2004-05-13 Thread Alex


was wondering if anyone out there is running a version of tomcat (i'm
running 5.0.19 and 5.0.24) with CGI enabled and *crosses fingers* has mrtg
installed somewhere with rrdtool?

For weeks now i've been trying to get the following cgi working:

http://my14all.sourceforge.net/14all-1.1.txt

It creates png files fine, but it doesn't spit them back out to the web
browser.  It has errors.

I've exhausted my resources and am hopeful someone on here has the
knowledge to let me know if it's infact something tiny within CGIServlet
that could be changed ... or well, i'm grasping at straws now.

Thanks.

Tomcat reboot runtime PS...

I'm leaving work now so I'm gonna have to leave this thread for a while
but I'll definitely check up on it again when I get in tomorrow morning.

If I get a chance soon I'll have a go at whipping something up.

I may be barking up completely the wrong tree and if I write something
of course it may well just crash  burn, but I'm intrigued and anyway it
would keep me out of mischief!!

RE: JProfiler vs. JProbe for AXIS webservices?

I have installed OptimizeIt on one Windows system and deployed

Um, Google?

Sun's website should have, in the very least, docs on the types of GC
algorithms available and how to invoke them.

: halt the whole server?

That depends on which GC algo you choose, which, in turn, depends on
heap analysis from profiling.

RE: Tomcat having strange 'hickups'

2004-05-13 Thread Ryan Lissack

Hi,

If it is running on a machine with multiple CPUs, you can use the concurrent
collector.  The collector then runs on one of the CPUs while the application
continues to run on the others, the other threads will still be suspended
for a short period (during the marking phase) but it can be an improvement.
Note that there is a trade-off in that the collection will typically take
longer.

First things first though, you should tune the size of the total heap and,
importantly, the size of your young generation.  This has a very large
impact on garbage collection performance.  You will of course have to
profile you app and test extensively to find the best settings for your
application.

I found the following links to be helpful:

Re: Revoking or deleting a client certificate


:I think previously I misunderstood you - now just for my understanding -
:I should create a selfsigned CA just for signing the server certificate
:and then import in the keystore the client certificates which are signed
:with the org's standard CA cert. And then the client browsers  should be
:made aware of this selfsigned CA in addition so that they can verify

:Is that right? (it sounds actually logical to me :-))

At least, theoretically, it should work.
That's the basic idea of a trust hierarchy.

Give it a shot, and please report results back to the list.

I haven't pondered the long-term effects of maintaining two separate CAs
(there are ups and downs) but I'll leave that as an exercise for you. ;)

Tomcat 4: JNDI LDAP - Can't get single role name

Hello Tomcat-Users,

I've got a problem and I don't know if it's my lack (...but I've already
scanned this list).

In my environment I want to authenticate the users against MS AD by JNDI
LDAP. The user authentication is ok and also the roles found by
getRoles() are the right ones. But the returned roles are given in the
complete distinguished name (DN) of the role (i.e.
CN=ERKUSAAdmin,CN=Users,DC=local,DC=bremereb,DC=de) instead of the
single role name (attribute cn) (i.e. ERKUSAAdmin) so I have to
configure the fully DN in web.xml for a security-constraint what is very
undesireable:

Default Directory

2004-05-13 Thread Andi Reinbrech

Hi,
 
With Tomcat 5.0.24 running as a service, where would the current directory
be?  5.0.18 allowed you to specify --WorkingPath %CATALINA_HOME%\bin in
service.bat, but this setting is ignored now in 5.0.24.
 
I need to open some config files from the current directory at startup.
 
BTW how does the technique work to grab a resource from the CLASSPATH?
Maybe I only need to put the config files in the classpath in that case.
(or in the WEB-INF directory of the service?).
 
Thanks!
Andi

RE: Tomcat 4.1.x Vs 5.0.x

2004-05-13 Thread dawg fan

From personal experience in testing on Suse 8.2 and tomcat 4.1.30 using a load of 
1000 concurrent connections pulling continuous pages from the webserver, the 
following was found:
- using ibm jdk and blackdown jdk (basically same thing) gave the fastest serve times 
for the first hour of testing.  unfortunately the serve times slowed drastically after 
1 hour under load.
- sun jdk server time results remained the same under the load for the length of the 
test (5 hours)


We concluded the sun jdk was best for our environment.  However it can be concluded 
that the ibm version is good if you do not need to handle that much load.

 The reason people cite for shifting away from the Sun JVM are

2 Tomcat instances on the same server ?

2004-05-13 Thread Hertenstein Alain

Hello,
 
I have a server with one single webapps running on Tomcat 4.1.29 and MS
IIS 6 (linked through the JK Connector) on Win2K, in production and
accessible through the web. Now I need to have a second application
running on Tomcat + IIS too, but I'm not sure what option to take :
 
1- install the 2nd web apps on the same Tomcat,
2- install a 2nd Tomcat instance on the server and have that 2nd web
apps running on that 2nd instance,
3- have a 2nd server installed with its own configuration.
 
The issues I foresee according to the options :
- option 1 : if any severe problem arises on any application which could
affect Tomcat (Out of Memory error, etc), the other apps would also not
be available. Also when re-deploying an apps, the best solution is
usually to stop/start the Tomcat service, which would automatically
shutdown the other too.
- option 2 (my prefered one) : best solution I think so far, but could
there be any conflict between both Tomcats running on the same server ?
What specific step should I take to have them running side by side
without problem (besides having a different HTTP port) ?
- option 3 : expensive solution, although the 2nd server is almost ready
and already running.
 
Any opinion about this ? Has anyone tried any of the options above in a
Production environment (i.e. servers up 24/7 all year with least
interruption possible) ?
 
Thanks a lot,
Alain

Option 2 would work fine as long as you change all the ports that it needs, there 
shouldnt be any configurational stuff other than that as long as the box has the 
memory and cpu to cope.

Option 3, if you have the server then might as well use it.

RE: how to configure the cookie-path-argument

2004-05-13 Thread Benjamin Armintor

I sympathize with your problem, Christoph.  After a quick look over the
code for the Coyote connector (which is likely what you're using), it
looks like the answer is no:  The session determination occurs in
CoyoteRequest, and the cookies are unconditionally written with the
context path of the request as the path value.  Because the cookie
handling is done in the internal Coyote request and response classes,
and the CoyoteConnector is the only configurable element, I suspect that
you'd have to re-implement some of the internals classes to change the
behavior for assigning cookie domain or path.

Subject: how to configure the cookie-path-argument 


Hi

I'm runnig tomcat 5.19 behind an apache.
apache is serving static contents and rewriting the requests (using 
mod_rewrite), for the rewrite-rules, see below.

the web-app /edit  has a Login-module, if login is successfull, the 
app /edit sends a cookie to the client with
Path=/edit(the setting of the Cookie is done with  
theHttpServletReqest.getSession(true)  ).
The value for the Path-attribute by default seems to be /appName  ... 
which for sure makes sense

since the client is sending its request to e.g.   
http://edit.hmb.ch/ServiceBroker   (or   http://edit.hmb.ch/de.html ),
but not sending to http://edit.hmb.ch/edit/ServiceBroker... the 
client does send back the cookie in the Request-Header (since for the 
client it's not a Request to  /edit ) 

in BEA-weblogic its possible to configure the path-attribute for the 
cookie for every web-app within the weblogic-specific weblogic.xml  (see

weblogic.xml - snippet  below)


is there a way to override tomcats default-behaviour for setting the 
path-argument of  a cookie,
e.g. in the web.xml   or may be in the server.xml (in the 
context-section) ...
... or has someone another hint how to set the Path=/

thanks in advance,

RE: 2 Tomcat instances on the same server ?

2004-05-13 Thread Ralph Einfeldt

I would go for 2.

As I'm not using IIS, I'm not shure if there are specific 
hurdles in this environment. Tomcat stand alone and tomcat
behind apache are quite easy to setup with multiple 
instances.

If all tomcate have the same versions, you just have to 
install tomcat once and setup two instances.

We were using references to the objects that we stored in the session

We are now changing our code to use the set... method after changes

RE: Default Directory


Hi,

With Tomcat 5.0.24 running as a service, where would the current
directory
be?  5.0.18 allowed you to specify --WorkingPath %CATALINA_HOME%\bin
in
service.bat, but this setting is ignored now in 5.0.24.

I need to open some config files from the current directory at startup.

BTW how does the technique work to grab a resource from the
CLASSPATH?
Maybe I only need to put the config files in the classpath in that
case.
(or in the WEB-INF directory of the service?).

Using Class#getResource is a great portable way to read configuration
files.  Place the config files under WEB-INF/classes, and then say (from
any object) getClass().getResource(/myFile.prop) to get a URL to the
file (for libraries that will take a URL), or getResourceAsStream to get
an InputStream for reading.  Read the JavaDoc for Class#getResource
(actually ClassLoader#getResource as you'll see) for full details.

Using ServletContext#getResource is similar and also very good.  Files
don't have to be on the classpath, they can be anywhere under the
webapp's root directory.  For example, put them under WEB-INF/config and
call getServletContext().getResource(/WEB-INF/config/myFile.prop) to
get the URL, or getResourceAsStream for the stream.

Either of those approaches is many times better than the current working
directory approach, which is the portability equivalent of a fly on the
path of a sumo wrestler to his food.

RE: Stop WA at startup

2004-05-13 Thread Ralph Einfeldt

Guessing that you are talking about starting instead of stopping...

load-on-startup is for servlets not for web applications.

If you include this tag in a servlet definition, the servlet will 
be started at startup time. The value for the tag defines the order 
of the startup.

RE: error shutting down the tomcat


Hi,
Your shutdown error means tomcat was already not running (or more
precisely, not listening on the server shutdown socket, 8005 by
default).

Shut down tomcat.  Make sure it's shut down using the ps command to show
its java process is gone.  Clear out your logs.  Start tomcat.  Look at
the logs for error messages.

Re: Timing service in Tomcat

2004-05-13 Thread Tim Kelly

Sasha,

We wanted to reuse our business java code for our batch runs so we 
implemented a cron job with issued a lynx command such as lynx 
http://webxx/servlet/batch?batch=2date=05/13/04. We run our production 
environment in linux  so lynx was available by default.

Sasha,

If you are used to unix cron and the format of crontabs, then you might
also want to have a look at JCronTab (http://jcrontab.sourceforge.net/),
which is supposed to work pretty well with Tomcat (have a look at the
first FAQ entry...).

I'm wondering what people are doing to schedule/execute tasks in Tomcat...

Is there any built-in timing services in Tomcat?  Are people using external
operating system tools like cron to invoke a class, or hit a servlet?
Is anyone using a good 3rd party scheduling framework?

Or is this kind of stuff home-grown right now (java.util.Timer, etc.)?  If
you've got your own timer, where do you initialize it (like in a servlet's
init() or a context listener)?
Thank you,

RE: Stop WA at startup


Hi,
Your message is vague.  However, take a look at the deployOnStartup flag
for the Host element in tomcat's configuration reference documentation.
It might not be exactly what you want.

Basically, if you don't want a webapp initialized when the tomcat server
is started, don't deploy that webapp.  You can always deploy it later
when you actually want it.

RE: Tomcat having strange 'hickups'


Hi,
It might be a big full garbage collection.  Add -verbose:gc to your
startup JVM options.  Use the system normally, and check the console log
as soon as you have one of those 20-second pauses.  If it says something
like
[Full GC: XXX - YYY (20 sec)]
then that's the culprit.  You will need to tune your GC parameters for
this high a load anyways.

Subject: Tomcat having strange 'hickups'

Hello,

I'm running Tomcat 5.0.18 on RedHat 9, started with the following
commandline:
/usr/java/j2sdk1.4.2_01//bin/java -Xmx256m -server
-Djava.endorsed.dirs=/usr/java/jakarta-tomcat/common/endorsed
-classpath
/usr/java/j2sdk1.4.2_01//lib/tools.jar:/usr/java/jakarta-
tomcat/bin/bootstrap.jar:/usr/java/jakarta-tomcat/bin/commons-logging-
api.jar
-Dcatalina.base=/usr/java/jakarta-tomcat
-Dcatalina.home=/usr/java/jakarta-tomcat
-Djava.io.tmpdir=/usr/java/jakarta-tomcat/temp
org.apache.catalina.startup.Bootstrap start

and with development=false and fork=true in the jsp servlet
configuration.

This installation is serving around 20 hits per day, much of it is
DB intensive.  Before i set development=false and fork=true I had big
hangups when I changed the JSPs and Tomcat started recompiling them -
the whole engine practically stopped for a few minutes and the load
went
up to 16 on the server.  Now development and fork variables are set
correctly for deployment, but I am still having a strange problem.
Every now and then (probably every few hours, I can't tell exactly)
Tomcat stops for around 20 seconds.  I noticed it when browsing one of
my sites, everything was working fast, and then at a certain point,
after I clicked on a link, the browser started connecting to the server
and waited for the response for a long time.  When I checked the load
on
the box it was 1-2 (normally it's 0.5), but didn't notice any processes
hogging the CPU with 'top'.  I already fixed all DB connection leaks I
had so that can't be the issue here.  Traffic peaks can't be it either,
I have constant traffic.

I know that this isn't a precise description of the error I'm
encountering but I don't have any more information at this point.  I'm
hoping that someone encountered this already and can help me, or
perhaps
you can give me directions how to figure out what's wrong.

Best regards,
W. Sobczuk

No I persist : stop appli : I don't want my web apps to be available after the tomcat

Each web app must be started by a human act.
the lack of load-on-startup in my web.xml doesn't give the wanted result.

Guessing that you are talking about starting instead of stopping...

load-on-startup is for servlets not for web applications.

If you include this tag in a servlet definition, the servlet will
be started at startup time. The value for the tag defines the order
of the startup.

The report writer we use from tonbeller software uses Servlets, we use
tomcat on IIS for this.

However our customer want to know the version (no problem) and the Patch
level - problem

How do you tell the patch level of the tomcat server you have
downloaded?

Do you have to install it 1st? Then do a
http://localhost:8080/manager/serverinfo

Command to get the patch level?

mod_jk.so for Fedora Core 1 x86_64

2004-05-13 Thread Brad Hafichuk

I've been trying to find a mod_jk.so binary to connect Apache 2.0.48 to Tomcat 4.1.29 
on my AMD64 server, which is running Fedora Core 1 x86_64. I've noticed that FreeBSD 
has a 64 bit version, any idea if someone is working on one for Fedora?

Cheers,
Brad

RE: mod_jk.so for Fedora Core 1 x86_64

There is an already build binary on the Jakarta.tomcat site!
Just go to binaries and search around!

It is a jk2 binary

The package works, I installed it!

Preparing to do session sharing

2004-05-13 Thread Randy

Hello,

I am upgrading my Tomcat Servers to 5 so I can take advantage of Session
sharing. I have two servers that I want to share sessions. As a side note,
this is in conjunction with using LVS, rh9 and apache 2

Before I try I would like to just clarify some things.

1) is it stable? I have seen lots of email traffic and some comments about
The only thing worse than dealing with connectors is Clustering

1a) do people have this working successfully in a high traffic production
env?

2) I am going to use Using in-memory-replication, using the
SimpleTcpCluster that ships with Tomcat 5 method

3) any real-life gotcha's or advise?

Thanks

Re: Timing service in Tomcat

2004-05-13 Thread Mats Henrikson

Sasha,

If you are used to unix cron and the format of crontabs, then you might
also want to have a look at JCronTab (http://jcrontab.sourceforge.net/),
which is supposed to work pretty well with Tomcat (have a look at the
first FAQ entry...).

Mats

On Wed, 2004-05-12 at 16:33, Sasha Borodin wrote:
 I'm wondering what people are doing to schedule/execute tasks in Tomcat...
 
 Is there any built-in timing services in Tomcat?  Are people using external
 operating system tools like cron to invoke a class, or hit a servlet?
 
 Is anyone using a good 3rd party scheduling framework?
 
 Or is this kind of stuff home-grown right now (java.util.Timer, etc.)?  If
 you've got your own timer, where do you initialize it (like in a servlet's
 init() or a context listener)?

RE : 2 Tomcat instances on the same server ?

2004-05-13 Thread Hertenstein Alain

Thanks Matt and Ralph,
Is there a documentation somewhere as to how to setup 2 (or more) Tomcat instances ? 
I've seen there were Workers on Tomcat 3.x, but cannot find more documentation for 
Tomcat 4.x (the Running.txt file doesn't explain much, I've created that CATALINA_BASE 
environment variable but cannot see any difference).
Also my 1st tomcat instance is already running as an NT service, and I'd like to keep 
it that way.

Another question : would these Tomcat instances be completely independent one from the 
other(s) ? I mean, could I completely restart one instance without affecting the 
others ?

Thanks again,
Alain

I would go for 2.

As I'm not using IIS, I'm not shure if there are specific 
hurdles in this environment. Tomcat stand alone and tomcat behind apache are quite 
easy to setup with multiple 
instances.

If all tomcate have the same versions, you just have to 
install tomcat once and setup two instances.

  Tomcat 4.1.29 on my AMD64 server, which is running Fedora Core 1 x86_64.
  I've noticed that FreeBSD has a 64 bit version, any idea if someone is
  working on one for Fedora?

  Cheers,
  Brad

Ahh, good detective work.  Explanation?  Something in server.xml and not

RE: JK2 still broken even in new version 2.0.4 with upload Stream ended unexpectedly error

2004-05-13 Thread Mladen Turk


It could be that he has a slow connection and is unable to deliver the
required data inside 60 second timeout period.
The data is read in 8K blocks, so if using slow connection that might be the
cause of the problem.

 Well, since using 2.0.4 this error has been unheard of until today. A user
 has been trying to upload a document and tried 4 times and constantly got
 the Stream ended unexpectedly error from JK2 connector. The document is
 Word and 140K. I have tested with other users trying to upload this item

tomcat and coldfusion: sharing webapp

Hi,
I am running Tomcat 5.0.24 on RH Enterprise Linux 3 with Apache web 
server 2.0.46 and mod_jk2 2.0.4.

I've a few Tomcat/Apache name-based virtual hosts and they work fine 
(JSP, servlet, etc.).

I would like to deploy ColdFusion MX 6.1 for J2EE on the top of Tomcat 
and share it for all the Apache/Tomcat virtual hosts.

ColdFusion MX is deployed as a webapp (WAR):
http://www.macromedia.com/support/coldfusion/j2ee/phase2-tomcat-deploy.html
http://www.macromedia.com/support/coldfusion/j2ee/cfmx-mac-onjrunandtomcat.html
Then it will process all files with the .cfm extension.

How can I enable ColdFusion support for all virtual hosts?

Can Tomcat share a webapp between multiple virtual hosts?

Thanks!

 My team is thinking about getting a profiling tool.  Does anybody have any
experience with either tool?  What are your thoughts about each one?

I've had mediocre success with any of them.

They all seem to basically do the same thing, they're all pretty darn slow,
and they've never really told us much that we didn't know already.

With our J2EE app, a lot of our issues turned out to be contention in the
container, something none of these tools were able to narrow down, isolate,
or identify (even some of the $$$ enterprise tools).

I've tried these tools, yet I still have better luck with strategically
placed Log4J statements, occasional thread dumps, and verbose GC chatter.
Even the stock hprof is basically usable, once you get the hang of it.

It's not that the tools aren't good, its just, to me, for the money, they're
not a good value over things that are readily available.

As a developer, you typically KNOW what's slow anyways, and a bit of logging
instrumentation goes a long way. If user X clicks on button Y and it feels
slow, that alone narrows down the problem.

For monitoring some behaviors, try BEA JRockit, it comes with a nice memory
profiler system built in. It also has a method profiler.

Finally, if you're looking for production logging, none of the tools
mentioned will help there at all. They're too expensive (performance wise)
to run.

If you have NO IDEA why you code is slow, these tools MAY help you. But in
that case they overwhelm you with so much data, that it's pretty much
hopeless. Wow, StringBuffer is the culprit. Yea, that's real helpful
information. We only call it 8000 times throughout the app.

It takes diligence and patience to tune your app, tune it one piece at a
time, make sure you can duplicate your results through load testing, and
make sure you only tweak one knob at a time, otherwise you may not know what
made it faster/slower.

Tune early, tune often.

One of the things we did was we wrote our own logging JDBC layer (they are
all simply interfaces, after all) which checks how long SQL queries take,
and logs those that hit a specific threshold. Dumps the SQL, dumps the bind,
whole ball of wax. Then we can go through that log on a regular basis to
tune queries, the DB, or the code. That helped a LOT for our system.

 Here's another take that's not seen often, but is intriguing: the
 java.util.prefs API.  It uses the Registry on Windows, and the

 running on Windows this is a decent approach (but then again if you're
 only running on windows you might make a whole set of choices based on
 that).

No, that's very clever. I had forgotten about that API completely, and it
handily solves the basic problem. I'll have to see how this works on a UNIX
box (i.e. does it write to a ~/.java_prefs directory, or what).

By using this API, you can plop a WAR on a server, then when the user first
tries to use it, run them through a configuration wizard.

Perfect.

You can also use Prevayler for object Prevalence...

If you use Prevayler in-memory only, then no configuration will be needed. 
Otherwise, if you want to persist across application restarts, then you will
have to configure a directory to be writable.  Of course, you can always use the

RE: Tomcat reboot runtime

2004-05-13 Thread Rudolf Feyerkleist

1. The original question was if there is some highly tomcat-specific code that enables 
a reboot at runtime. Spending very little time going through the source code of 
catalina, it seems to me that even highly tomcat-specific code does not support a 
reboot a runtime.
2. One solution could be to call a shell script from within the webapplication running 
on Tomcat, reboot Tomcat, accepting in this way that the application and tomcat will 
be unavailable during some reboot time. On the other hand, this could not be regarded 
as a good coding practice, in my opinion.
3. Another solution could be to have the application create a new process in the JVM 
responsible for stopping and starting the tomcat service. But then again this process 
could only do so by calling a script as in the solution proposed in 2, with it same 
consequences (seems to me I might as well be wrong).
 
I would be very pleased with any comments on the above
 
Rudolf Feyerkleist
 
NB As a relative novice to Tomcat it astonishs me that the Tomcat Manager does not 
provide the functionnality to reboot the server at runtime (taking in account that it 
services become unavailable during reboot time).

Linux memory management with Tomcat question

I've got tomcat running on a Linux machine with 2000GB of RAM.  The tomcat settings 
are JAVA_OPTS=-server -Xms1500M -Xmx1500M; therefore, when i start Tomcat, I'll see 
free memory drop to about 500MB - which is expected.  But, when tomcat is running and 
especially under heavy load the free memory continues to drop while buffer and cache 
rises.  I understand that Linux places all used memory into the buffer and cache and 
puts it back to free memory when needed.  But I'm confused as to why free memory would 
be used at all since 1500MB of memory has already been allocated to Tomcat.  I mean, 
why isn't it pulling from it's own heap instead of consuming Linux's free memory?

TempDir???

2004-05-13 Thread Steve Vanspall

Hi there,

I have been reading about ways to get Tomcat to write to a file.

Basically I need to write a file, that only needs to be available while
tomcat is running. It is used by a background process to dynamically
configure itself, depending on what configuration tomcat is running on at
that time. When tomcat shuts down it will delete this file, thus indicating
to the background process to shut down also.

My problem is, that in Linux I cannot just write to the /tmp directory.

Is the javax.servlet.context.tempdir attribute set to a defualt of some kind
or do I have to set it myself.

If it is set to a default, how do I access it
getServletContext().getAttributr(javax.servlet.context.tempdir) returns
null.

If I ahve to set it, what permission to I have to give the directory it is
to be?

Thanks in advance

Steve

Option #4: a listener that exists outside the Tomcat process, which

I'm whipping up a prototype now: it's a basic socket listener that

I'll have a link tomorrow...

It's *possible*, certainly.  The source code's available for anyone to

Re: Linux memory management with Tomcat question

2004-05-13 Thread Peter Lin


ok, so your server has 2GB of ram or 2000Mb.

the memory usage may increase for several reasons, the
primary one is there's a slow leak in one of your
applications. This may be as simple as several objects
referencing each other. If they happen to result in
circular references, the garbage collector may not
reclaim the heap memory if the server is under
moderate load.  Eventually the VM would garbage those
objects, but for the short term it would look just
like a leak.

Another possible cause is if the sessions are set to
never expire or expire in a very long time, like 1 day
or greater. In general, I profile my webapps and use
JMeter to simulate load. I strive for flat memory
usage under constant load. A simple thing like
clearing all the arrays or nulling references in a
object structure will insure the heap is garbage ASAP
instead of several minutes. Say I make an object model
for some data that has a hierarchical structure. Once
I'm done with translating the data into HTML, I clear
that object structure to make sure the heap is
garbaged efficiently. I hope that helps.
