Re: [OT] Tomcat Server CPU utilization goes upto 400%
Do as Tim Funk suggested, issue a kill -3 to tomcat when CPU usage gets
high to get an idea of what java Threads are currently doing. Issue a
few kills to get a better view of what part of process takes times. If
it's not enough to find the location of issue, you might want to invest
time in using a profiler to locate problem (attach profiler to running
jvm when it starts to consume CPU).

There is an application deployed that refreshes after every 30 seconds.
After every 30 seconds, it requeries database and fetches the data. This
was a design requirement for this application. Generally large numbers
of sessions of this application are running (450-500).

i think its more to application problem instead of tomcat problem. Is
there
any application hosted inside tomcat that get infinite loop or use a
kind of
loop checking something that utilize the thread fully ? try solving that
with the application developer

Problem with JVM, and Tomcat tuning
Hi I'm running Tomcat 6.0.13 on Sun Java6 and Linux. I upgraded from Tomcat 5.5.17 and Java5 update 9 a couple of weeks ago. I experience random crashes of the JVM on a daily basis. It simply fails with segmentation faults, double frees and similar. Are any of you experiencing similar problems? I had the same problems with Java5 and Tomcat 5.5, but less often. If I submit a bug report with Sun I get a reply that I should contact Apache because the problem seems to be triggered by Tomcat. Is anyone at Apache interested in those hs_err_PID.log files generated by the JVM? So, how would I go about avoiding to trigger these sorts of problems? It is a production system and I'm not very happy about it being down almost daily due to bugs in the JVM. I should add that I run my fairly memory consuming application on a 32 bit server with 4 GB of physical memory and 8 GB of swap space and with CATALINA_OPTS set as: CATALINA_OPTS=-Djava.awt.headless=true -server -Xms512m -Xmx2g -verbose:gc -XX:+PrintGCTimeStamps -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:+UseTLAB -XX:+UsePerfData -XX:NewSize=128m -XX:MaxNewSize=128m -XX:MaxTenuringThreshold=0 -XX:SurvivorRatio=1024 -Xincgc I tried some even more agressive garbage collector settings a while back because I was experiencing long pauses while the garbage collector was running, but I kept triggering loads of segmentation faults. This is the settings that around a year ago gave the best balance between crashes and halts from the garbage collector. But are these settings optimal for Tomcat 6 and Java6? -- Jacob - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Jyothi Cant really understand what you saying, but suggest the following If you using Netbeans and want to run the ant scripts from you project manually, then after you build it, flip over to the file tab, find the ant script you interested in and right click on it, NB has very cool facilities to play with ant... can even debug your script. If you trying to deploy Tomcat war files... then go to the tomcat site and download the standalone deployer package, it has the ant script you need already, and the relevant help files. good luck - Original Message - From: bhagya jyothi [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Thursday, June 14, 2007 8:36 PM Subject: deploying ant Hi all, AM new to Ant build tool and was jus writing an application.am done with my programme and when i give ant in my present working directory at command prompt its fine.when i give ant deploy or ant deploywar it's saying Build Successfull but nothing is there under build and deploy.also when is gave ant list-- nothing is shown under my current directory.And giving ant install its saying [Install] FAIL-Failed to deploy application at context path/(my working directory) BUILD FAILED. can any one tell what to do exactly so that i can run it successfully...waiting for a wuick reply.

Re: Trouble with APR and Tomcat 5.5.15
Hi I had similar problem on Ubunutu Linux. Logs have been saying something about inability to bind to socket. If log clearly says that address already in use (probably 8080). Check that no other application using this port. If log says something like: java.lang.Exception: Socket bind failed: [22] Invalid argument Then try to disable ipv6 in your OS. This helped me. * Best Regards Ilja Jarrod Cuzens wrote: Hi All, We are currently experimenting with APR and libtcnative on our machines. We have a machine in test that we configured and things when quite smoothly (although it was RHEL4 and the production box we are testing is CentOS). When we start tomcat and include all the relevant library paths in the java.library.path we can see APR attempt to load but it continually fails and reports that the socket was already in use. When we remove the java.library.path (effectively turning off APR) we restart and the server starts correctly with no complaints.

Check the manager app and see how many ajp connections are in use. If your lucky maybe tomcat is not seeing the dropped apache connections. In which case - I forget how to fix this.

Re: Tomcat 6 classloader leak in Commons Pool
Hi, I have found what you said about the factory. It is ported to 6.0. I have tried to use the old commons-dbcp library, copying commons-pool-1.2.jar and commons-dbcp-1.2.2.jar in tomcat lib directory and defining the attribute factory=org.apache.commons.dbcp.BasicDataSourceFactory in the resource in my context.xml. It works, but I still have a memory leak. Tomcat is retaining my new commons-dbcp classes, and I think it is related to this classes: org.apache.tomcat.util.modeler.BaseModelMBean, com.sun.jmx.mbeanserver.NamedObject, com.sun.jmx.mbeanserver.RepositorySupport. com.sun.jmx.interceptor.DefaultMBeanServerInterceptor com.sun.jmx.mbeanserver.JmxMBeanServer, This part of Tomcat is completely unkown to me, Do you have any clue? Many thanks for your help Diego David Smith escribió: In older versions of tomcat (5.0.x) there is a factory attribute defining the pool to use.

Re: Stop deployOnStartup for only one webapp
Mark,
Thanks for the reply. First, let me explain sakai a little... Sakai is
a learning management portal. The architecture is such that if you want
to add a feature, you create a new webapp and tie it into the portal
app. All service implementation details are deployed out of
${CATALINA_HOME}/components due to their nifty classloader, and all
webapps access these services staticly either by an internal lookup, or
factories almost entirely injected by spring. This one webapp is a
built-in quartz scheduler we use to import our student/course data from
our course management system (Banner). The job defs are held in the
DB. If there are more than one scheduler deployed, the first one that
checks in and the job is available to run, gets the privilege of running
it. This job reads banner via jdbc, and writes to sakai via the sakai
services api (deployed via components). So we have complete dependency
on these static configured services being present and configured
correctly. They are all dependent, there is no breaking it up.
I think the best thing to do is to actually hack the code and place an
init-param that starts/stops the job listener. That would be cleanest,
and actual require the least amount of effort. If there was a context
specific override for deployOnStartup, that would have worked to...
Thanks for your time,
- Joe

What happens when you place the application outside of appBase, create
an explicit Context (PATH.xml) with docBase pointing to it, and flip
the Context file into/out of $CATALINA_HOME/config/Catalina/localhost ?
It shouldn't be too hard to arrange for a startup script to delete
certain Context files before Tomcat starts, and then you can copy one
in later when you want it.

Your error sounds your mapping is wrong, because tomcat does not seem to find your servlet. Have a good day, and i recommend you to work with good tools.

Re: Using shared Spring Webapp in Tomcat 6
I understand it makes no sense to share a whole webapp in Tomcat. What about sharing a singleton across all Tomcat webapps? I want my main webapp to call a method on that shared singleton in order to provide a factory (...getInstance().setFactory()). This factory should be retrieved by webapps using that singleton (getFactory()). I know I have to put that singleton (in a jar file) into the $CATALINA_HOME/lib directory. How do I access the singleton from within my webapps after that? I guess I have to touch the web.xml somewhere. However, the first call must set the factory (the main webapp will do that)... all following calls shall be able to access the factory. - Original Message - From: Caldarale, Charles R [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Friday, June 15, 2007 12:08 AM Subject: RE: Using shared Spring Webapp in Tomcat 6 From: Kevin Wilhelm [mailto:[EMAIL PROTECTED] Subject: Using shared Spring Webapp in Tomcat 6 For Tomcat 6 there is a folder called $CATALINAHOME/lib that is said to be used for that kind of stuff.

Re: Fwd: building mod_jk 1.2.23 apxs errors
What are the contents of your mod_jk.la file? What is the output of doing make, especially the parts close to the end, like shortly before and all after the line Making all in apache-2.0 After all it looks, like you are doing a static apache build. Note, that neither '--enable-module=most' nor '--enable-shared=max' exist as 2.0 httpd configure options. Look at http://httpd.apache.org/docs/2.0/programs/configure.html If you really want to do a static compilation, have a look at the page http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html especially around the places where with-apache is mentioned. A little warning: static mod_jk compilation most likely is not done very often. So this procedure might be slightly broken on some platforms.

From: Kevin Wilhelm [mailto:[EMAIL PROTECTED] Subject: Re: Using shared Spring Webapp in Tomcat 6 I understand it makes no sense to share a whole webapp in Tomcat. Still not clear on what you mean by share a whole webapp. By definition (the servlet spec), webapps are intended to be independent and the interface to a webapp is via HTTP. You can easily send an HTTP request from one webapp to another within Tomcat, if that's what you want to do - but I suspect you really want to use method invocations. What about sharing a singleton across all Tomcat webapps? That's fine, and it doesn't have to be in a jar - you can put just the .class file into the $CATALINA_HOME/lib directory. How do I access the singleton from within my webapps after that? Just call it; the webapp's classloader will delegate to the common classloader if the reference can't be found within the webapp. However, the first call must set the factory (the main webapp will do that) You might want to consider using a Listener to initialize the singleton.

Re: Problem with JVM, and Tomcat tuning
Give us a look at your hotspot error files. Do they look very close to each other, or do they show very different stacks as the reason for the crash? If double free is really the reason it won't be caused by a pure Java Tomcat, instead it could be native libs integrated into your webapps by JNI or a bug between the JVM and your platform. Nevertheless a view at your hotspot error files should give a hint. A second thing: since some of your JVM options are very advanced, consider upgrading to Java 1.5.0_12. JVM updates are usually low risk and easy to do and most of the patch releases enhance stability of the more advanced GC options.

you also configured Apache to locally handle *.cgi as a CGI itself. So

the internal ordering of the two modules in Apache).
You need to either disable forwarding for the *.cgi in mod_jk
(JkUnmount; if you want Apache to do the cgi) or disable Apache cgi
handling (not using mod_cgi, SetHandler for .cgi etc.) if you want
Tomcat to handle cgi.

Re: Tomcat - Apache ... and CGI
Thanks Rainer, I see what's happening now !
I think I will go for the first solution you've suggested (disabling
Tomcat cgi handling) and let Apache doing this, just because some cgi
applications are already running on the serer I'm using.

As I understand you, you want to let Tomcat handle the cgi for you. But
you also configured Apache to locally handle *.cgi as a CGI itself. So
you need to resolve the conflict between handling everything that starts
with /Context/ by mod_jk and everything that ends in .cgi by mod_cgi.
/Context/*.cgi is now no longer well defined (the handling depends on
the internal ordering of the two modules in Apache).

thank you i got that On 6/16/07, Rainer Jung [EMAIL PROTECTED] wrote: Are you actually using -Xrs? At least it's not contained in the part of the commandline you posted, which is unfortunately truncated. The result of kill -QUIT goes to STDOUT of the jvm. So you need to find out, where your STDOUT goes to. The standard tomcat start scripts (startup.sh or catalina.sh called with the argument start) redirect STDOUT to logs/catalina.out.
