Re: Tomcat hangs after some time
We are running on the following platform: Windows NT 4.0 SP6a Tomcat 3.3.1a (The problem originally occurred on 3.2.4, we upgraded to 3.3.1a hoping to solve the problem) Sun Java SDK 1.3.1_08 Hi, I have heard of Tomcat hanging in some situations up to 4.1.24. However looking at the above list you are running very old stuff. You might want to upgrade to a new JDK and to Tomcat 4.1.27. I'm pretty sure people are going to tell you to upgrade those before you do anything else. (since they are old... it would be one thing if you are on 4.1.24 but 3.x is very old) -e - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: permissions for Tomcat+Apache integration
Hi, The question is do you need to secure your application from the outside world or do you need to secure it from users that might be logging on to your system? Or both? Usually you want to go with the both scenerio. But to keep it simple, pick a user that you want tomcat to run as. Untar Tomcat and chown -R tomcat jakarta-4.x.x (if the user is named tomcat which isn't a bad name for the Tomcat user ;) Then just run it. It will be ok just like that. If you are running Tomcat and Apache on the same machine really look at why you are running Apache at all. It's a popular misconception that you _must_ run Apache in front of Tomcat. That couldn't be more wrong. Running Tomcat alone will save you the hassle of Apache and the connectors. However you do need to run Apache if you are going to use load balanceing and the apache modules. However most times people just have Apache pipe everything back to Tomcat. In this case you don't need Apache at all. -e On Mon, 1 Sep 2003, [iso-8859-1] Sonja Löhr wrote: Hello! Here is my second question, now concerning Apache+Tomcat integration on Linux: Could someone tell me a reasonable users, groups and file permissions structure for apache, the tomcat-files itself and a typical webapp? - Java security aside. 1. Is it a good idea at all to place the webapps under apache's document root, having to care about all WEB-INF and other sensible directories with deny from all ? 2. Which account in which group? Apache needs access to static files somewhere in the webapp. (Which may be very dispersed f.e. in case of cocoon). If a tomcat user and the apache user account are in the same group with restricted permissions, I can't assign permissions to a group of developers, just another owner (me ;-). Ok, may it be. Additionally, if tomcat unpacks war files, all resulting directories are owned by tomcat alone. So should I put the apache user into the tomcat group? 3.How paranoid must I be about tomcat-files (server-directory f.e)? Tomcat needs write access to some directories, but certainly I don't know all processes tomcat. You probably guess by now that I'm not grown up with Unix-systems.

Re: port 8009 security (ajp13)
Hi, Firewalls. In a single box setup you would have a firewall that would only allow access to port 80. Apache would get the request and forward it back to itself on port 8009.

Re: Jvmroute and worker names?
Hi, jvmroute names don't equate to the names of the workers in your properties file. basically all jvmroute does is tack that name on the end of the session id so the connector knows what tomcat to send the session to in a loadbalanced env.

Re: Oracle connection pooling

Your connections should be done well before that. -e On Fri, 8 Aug 2003, Cristopher Daniluk wrote: We are running a fairly large ecommerce site consisting of 3 apache 2.0.48 servers being balanced between using UltraMonkey/ldirector and 2 tomcat servers with AJP1.3. Everything is Linux except the back end which is a fairly hefty and firewalled Sun running Oracle8i. The webapps build a connection pool to oracle via the oracle.jdbc.pool.* connection pool. The pool instantiates fine and everything is great, but gradually the pool begins to break down. Idle connections are closed by Oracle (not sure if its oracle itself or the fw..), but the oracle pool doesn't figure it out. If someone happens to get the dead connection, Tomcat completely hangs on all threads until the session-timeout expires. Even the session replication code stops and the apache servers and the other tomcat in the cluster mark it offline. During the peak traffic it isn't so bad but at the end of the day after load goes back down, it's a big problem. We initially used DBCP but it didn't work for crap with Oracle. Is there a better pool to use with Oracle and Tomcat in a cluster environment and if not, is there a way we can get the Oracle pool to recycle some of these bad connections without blowing up the server?

Rather than recode in order to deal with it (and I don't know what that would entail) we found the three sites our site needed to access and allowed our site direct access to them with no proxy by changing the firewall rules. -e On Wed, 6 Aug 2003, Tim Funk wrote: Unless I am missing something, tomcat by default does not have the ability to make outbound HTTP requests.

Re: Hardware loadbalancing with JK2
Hi, Using the CSS between Apache and Tomcat seems a bit overkill as Tomcat provides all the functionality that a CSS would. However I think you can get it to work. All you need is a single worker to the CSS. From there the CSS should bust it out and spread it across the various Tomcats. There wouldn't be any loadbalancing in the JK2 configuration. Just like a web server might have multiple hosts behind it, to the outside world you only see one IP. Same thing goes for JK2. I don't have a properties file handy but search the archives and you'll find an example. You just want a real basic single worker config. I think there might be one in the JK2 docs. Make sure to configure the CSS to make the sessions sticky by some mechanism (unless you are using clustering) otherwise Tomcat could goof up. -e On Mon, 11 Aug 2003, Mark Gastel wrote: Hi, I am trying to get hardware load balancing to work between apache 2.0.46/mod_jk2, a cisco css and tomcat 4.1.27. The way this works is an ajp13 service has been created on the css. Apache talks to this css ajp service which is split among several tomcat instances... Now the problem: Because mod_jk2 seems to have some form of connection caching going, when I disable a tomcat instance it still receives ajp13 connections. Is there a way to disable the connection caching in JK2 and forcing it to establish a new connection with every hit? I know this would give a performance hit, but it will give me fine grain control over how traffic is distributed.

Make sure you have a connectionTimout defined in your server.xml for the coyote connector. By default it's 0 (which I gather to be infinite). Setting it to 6 or 12 will make the connection timeout.

However I think you can get it to work. All you need is a single worker to the CSS. From there the CSS should bust it out and spread it across the various Tomcats. There wouldn't be any loadbalancing in the JK2 configuration. Just like a web server might have multiple hosts behind it, to the outside world you only see one IP. Same thing goes for JK2. I don't have a properties file handy but search the archives and you'll find an example. You just want a real basic single worker config. I think there might be one in the JK2 docs. Make sure to configure the CSS to make the sessions sticky by some mechanism (unless you are using clustering) otherwise Tomcat could goof up. -e On Mon, 11 Aug 2003, Mark Gastel wrote: Hi, I am trying to get hardware load balancing to work between apache 2.0.46/mod_jk2, a cisco css and tomcat 4.1.27. The way this works is an ajp13 service has been created on the css. Apache talks to this css ajp service which is split among several tomcat instances... Now the problem: Because mod_jk2 seems to have some form of connection caching going, when I disable a tomcat instance it still receives ajp13 connections. Is there a way to disable the connection caching in JK2 and forcing it to establish a new connection with every hit? I know this would give a performance hit, but it will give me fine grain control over how traffic is distributed.

RE: Help! heavy traffic is crapping out our site every 5 min! DBCPexceptions
Hi,
Do a ps -ef (or ps -aux) and find out the PID of the java process (your
sys-admin can help here). Then do a 'kill -QUIT PID' where PID is the
PID of the java process.
It will send the thread dump to the catalina.out file.
Deciphering the thread dump is a little difficult if you have never done
it before and it is out of the scope of this list. Suffice it to say you
can see what lines of code your threads are on.
Typically when you hang up your DB connections you will see a bunch of
threads hung up on the same class. Then you will see one just a little
further ahead. Typically this is the thread and class that all the others
are waiting for to finish... so the other threads can finish. It's
important to get as many thread dumps as you can as fast as you can right
in a row.
You have to read up, so to speak. Google is your friend.
Hope this helps.

Sorry, I sent this a little to soon...
Get 5 or 10 thread dumps in a row real fast... just bam, bam, bam, etc...
From that you can tell what the threads are doing. They should be moving
through methods (or classes) very quickly. If they are sticking they are
waiting on something and that's typically bad.
Find what they are sticking on and fix it. :) Simple, eh?

Yup, and when nothing is happening, the # of active connections should

I do have an apache installation that is a bit peculiar. To make ist short,

Now the website says the following:
The config file is named workers2.properties, located by default in

Hi, Try playing with the connectionTimout setting in your server.xml. By default it is set at 0. Try using 12. Also experiment with -1. I have found that the connector resets every once in a while with a 0. With 12 the connection doesn't reset but times out.

Someone can explain how analize data from a kill -3 ( thread dump ) . I can see nothing rare. Google for this. You could write a book about this subject and I don't think this is the right place to do it. Basically it's used to see if threads are blocked or hanging on a piece of code. If you are experiencing this you will notice that you have a bunch of threads all stuck in one place and then one that's just a little bit further along. Typically that's the one all the other threads are waiting on to finish up whatever it's doing so they can move forward. Find out what it's doing and debug that code/DB call/whatever. -e - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: CiscoLB jk2 problem
Hi, This is why you want to spread your application across two or more tomcats. I'm not sure if you can tweak the behavior of the error because what you are getting is indeed a internal server error. If you are going to load balance you should try to load balance all the way down the stack. Try giving each apache two or more tomcats to send sessions too. JK2 will see that tomcat A is down and move to tomcat B. Your application monitoring software should then kick of an alert to notify someone that a tomcat is down and might need human intervention. -e On Thu, 31 Jul 2003, Angus Mezick wrote: I need to let apache fail nicely when a tomcat instance has crashed, been stopped or is being restarted.

Re: Possible configuration error in JK2-Environment (Apache 2.0.46,Tomcat 4.1.18/24)
Hi,
Here is a minimal JK2 config. This is a default config so you need to
change port 8009 below to port 9000 per your server.xml
workers2.properties:
bash-2.05$ more workers2.properties
[shm]
file=${serverRoot}/logs/shm.file
size=1048576
# socket channel
[channel.socket:localhost:8009]
port=8009
host=127.0.0.1
# define the worker
[ajp13:localhost:8009]
channel=channel.socket:localhost:8009
# Uri mapping
[uri:/*]
worker=ajp13:localhost:8009
http.conf: (change the path on the JkSet line for your system)
LoadModule jk2_module modules/mod_jk2.so
JkSet config.file /full/system/path/to/workers2.properties
jk2.properties should be all commented out.
server.xml should just the default JK2 settings.
That's it, nothing more nothing less. It should work. Then you want to
go back and adjust workers2.properties for your contexts, maybe add a
logger, whatever.

I guess that's another generalization. :) Specifically, setting up TC, using it w/Apache and IIS, TC Security, clustering TC servers, setting up JNDI resources. I suspect any good TC book will have a good deal of overlap w/the servlet spec v2.4 which is fine.

doy. it's listening. forget about that.
you have checked to make sure that the file (index.jsp or index.html) is
there?
if you go to change the uri in workers2.properties to /* instead of
/examples/* and go to http://localhost/ what do you get.
Do you see anyting in the logs?

Re: Tomcat 4.1.18 crash.
Hi, If it hangs get a thread dump by sending a 'kill -QUIT' to the process (Unix only). That will tell you more of whats going on in the VM than the logs do. From it you can tell where the threads are getting stuck. Hopefully that will point you in the right direction to debug. I think there is a way to get a thread dump on Windows but I don't know what it is. Google is your friend. Reading the thread dump might be a little confusing if you haven't done it before. Again, google is you friend. -e On Tue, 29 Jul 2003, EXT / ALTIOR CABOU Carl (DRT) wrote: Hi all. I'm using Tomcat 4.1.18 with Axis 1.0.

It's scripting language is very rich. But like I said it isn't free. In fact unless you have budgeted for it chances are it will be difficult to cough up the dough for it. -e On Tue, 29 Jul 2003, Mark W. Webb wrote: does anyone have experience load testing tomcat?

Re: Tomcat Crashing on Linux
Earlier today we were talking about thread dumps. You might want to generate some next time this is happening. It will show you if a thread is locked and what it is waiting on. send a kill -QUIT to the VM when it is hanging.

For tomcat, I have a daemon script that has a status command that tells you all the pid's of processes for tomcat. You can get it off my web page: http://daydream.stanford.edu/tomcat/install_web_services.html You can just use the command I use for that which is on the web page also. You should do something similar for Oracle to see how many processes are in the process table. You could try and restarting the database, which would clear out connections that aren't timing out, and see if tomcat starts responding again. You say it's crashing, but is it really? It clearly has problems restarting and is not responding. But that may not be the same as crashing. Are there processes showing tomcat is still up?

Re: coonnectionTimeout
Hi, Good question. I always thought of '0' as being infinite and I wasn't aware of -1. One difference I see, and this seems to be Solaris specific, is that when I use '0' I get INFO: connection reset messages in Tomcat from the Connector. When I give it a time out of say 12 I no longer get reset messages but I get INFO: connection timed out in the logs. I'm planning on running a test to see what the user experience is with a timeout. I know that during the resets the user sees HTTP 400 and 500 errors. I'll also now test with -1. -e On Mon, 28 Jul 2003, Geralyn M Hollerman wrote: I have a question about the connectionTimeout attribute of a Connector element in server.xml; from what I've read, the default value is 6 (milliseconds), but the server.xml that came with the 4.1.24 that I downloaded is set to 0.

Re: Tomcat Education
The Professional Apache Tomcat book is a good foundation how Tomcat works but it is intended for more of a sys-admin type than a developer. I thought it was pretty good on that aspect. Not many books cater to the poor admins who could really care less about the inner workings of someones tag library. Various servlet and Struts books can help you with the java. This list is a good place to learn. It is the only source you will find that is up to date.

Re: A problem with configuring tomcat with apache.
Hi, This is the mod_webapp config that comes with Solaris.

Re: Best Tomcat Book, Recommendations??? PART 2
Hi, I don't usually push books... people have different tastes. But I like the Wrox book. It's an administrators book. Basically how Tomcat is designed from an architecture standpoint (containers, contexts, valves, realms, what the directories are for, etc) and how to configure it (connectors, JDBC, JNDI, etc). It leaves out java and it assumes you know xml. Of course it's getting more and more out of date as we speak. I think Tomcat 6 will be out before a decent Tomcat 5 book hits the shelves. -e On Mon, 28 Jul 2003, Tony LaPaso wrote: Sorry, but I forgot to mention: I'm really only interested in Tomcat specifically, not how to program servlets/JSPs.

Re: Need Help For Iplanet Tomcat Configuration
Hi, I'm not sure if cross posting like that was such a good idea... But since I just had to figure this out last week I will share what I learned. I had to play with this a bit befor I was able to get it to work. I was using Solaris so I can't help you with the correct version of the redirector DLL. I hope this will help. Object name=servlet ObjectType fn=force-type type=text/plain Service fn=jk_service worker=ajp13 /Object The documentation isn't entirely correct here. Put servlet in quotes. Otherwise iPlanet doesn't see the object name and the assigment you made in the default object section won't work (you will get that error once you fix the stuff below). It also wouldn't hurt to put text/plain in quotes. workers.worker file workers.tomcat_home=C:\Tomcat workers.java_home=C:\jdk1.3 ps=\ worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp13.type=ajp13 I just used to last four lines of what you have here. But that shouldn't matter. I tried this url http://localhost:81/examples/servlet/HelloWorldExample [25/Jul/2003:12:59:08] warning ( 212): for host 127.0.0.1 trying to GET /examples/servlet/HelloWorldExample, send-file reports: can't find C:/iPlanet/Servers/docs/examples/servlet/HelloWorldExample (File not found) That's exactly what it is doing. So you have to fool it. In your iPlanet docroot create the directory examples. iPlanet will see it and think it's there. Then when it tries to serve it the changes in obj.conf will kick in and send the request to tomcat. In some cases you will find that you have to touch (create 0 length files) in some cases to fool netsacpe into thinking it's there. Usually it's just index.jsp.

Re: iPlanet and Tomcat integration on solaris
a) The remoteUser is not being passed from iPlanet to Tomcat. My JSPS are reading the remoteUser using the request.getRemoteUser() method.

I looked at the source code for the version of nsapi_connector.so that I built from jakarta-tomcat-connectors-4.1.24.src. It looks to be assigning to remoteUser the value of auth-user in the request-vars pblock. this value is definitely set in that pblock.

RE: Tomcat not working behind a NAT?
I still think you are barking up the wrong tree here. If I had to guess I would say that 95% of all internet faceing Tomcat servers are behind some kind of NAT device. One thing to consider. NAT only translates the IP in the IP header and doesn't change the data payload. So if you are, for whatever reason, using an IP address that is getting sent along in the payload and trying to redirect to it or whatever, NAT won't change that. Kinda how SQLNet doesn't like NAT devices. Because the users IP is embedded in the payload as part of the protocol. So it goofs up when the IP header and the IP in the payload don't match. But what you are thinking below is the first thing I would do. Make sure the machine on the outside see's the correct hostname/IP number and the machine on the inside see's that same hostname as the inside IP address. You can do that via the hosts file if you like. -e On Fri, 25 Jul 2003, Erin Dalzell wrote: For this particular Servlet call we are not accessing any databases. DTDs?

My question is, is that forward call a full http request? If so, what ip address will it use? I think that it is trying to use the 3.3.3.3 address and the NAT doesn't like it. Well ya. That's kinda what I've been saying. Don't hardwire the IP. So instead of using an IP use a hostname. For example www.myapp.com = 3.3.3.3 on the external DNS.

Re: TCP/IP issues with tomcat 4.1.24
Hi, That's interesting. I haven't seen it but it's interesting. Just curious, when the systems is exhibiting this behavior and you try to bring up a browser and re-inact a testing scenerio what happens? Is the system still responsive? Can you duplicate the error by hand? When you get that error what is the user experience? I spend about as much time debugging testing tools as I do application systems. So I'm wondering what could be so different in 4.1.24 that would cause that. I think it's odd that it would goof up on the TCP because that's handled at a much lower level. It's also odd that the clients exit out instead of chalking it up as an error and restarting themselves. That just might be a limitation of your testing tool though. Check on the health of your testing tool (RAM, CPU) when it cracks up. I don't know what kind of system you are using but make sure to check the basics. Make sure you have forced the systems (and the testing tools and any switches in between) interfaces at 100 FDX (no auto-negogiate) and tune the TCP settings. That makes a world of difference. -e On Fri, 25 Jul 2003, McClure, Timothy J(IndSys, GE Interlogix) wrote: We have a testsuite that sends 3 messages per second from 100 clients.

Re: Tomcat not working behind a NAT?
Hi, I was unaware that tomcat connects to itself on a high port. Never the less, Tomcat should be completely unaware of the 204.1.1.1 address. If your NAT is totally transparent the only place that IP lives is on the external interface of your firewall/NAT device. I don't see how that IP could sneak back there. Unless, and I'm going to guess here, your application is looking at the URI of the request and doing something with it. In that case you should use IP numbers and have internal vs. external DNS (or /etc/hosts) set up with the different IP numbers (one for the inside value and one with the 10.x.x.x inside value). So that way if it tries to connect to the same URI that was in the request it will get the right 10.x.x.x IP number. I don't know if that helped or not. -e On Thu, 24 Jul 2003, Erin Dalzell wrote: Hi there, We have just discovered that our tomcat web app is not working correctly behind a NAT.

But if I access it from an external site, tomcat tries to communicate with itself on the 204.1.1.1 address and the NAT doesn't like it. So, I have a few questions: 1) why doesn't tomcat (we are using version 4) use localhost to communicate with itself? 2) anyone else seen this problem? 3) can the high port be configured? Thoughts?

Re: Tomcat not working behind a NAT?
Heh.. ya. That didn't all come out right. Use a host name instead of IP numbers and have internal and external DNS set up with the internal and external IP numbers of the host respectively. That's better. -e On Thu, 24 Jul 2003, John Turner wrote: Made sense to me. :) John Eric J. Pinnell wrote: Hi, I was unaware that tomcat connects to itself on a high port. Never the less, Tomcat should be completely unaware of the 204.1.1.1 address. If your NAT is totally transparent the only place that IP lives is on the external interface of your firewall/NAT device. I don't see how that IP could sneak back there. Unless, and I'm going to guess here, your application is looking at the URI of the request and doing something with it. In that case you should use IP numbers and have internal vs. external DNS (or /etc/hosts) set up with the different IP numbers (one for the inside value and one with the 10.x.x.x inside value). So that way if it tries to connect to the same URI that was in the request it will get the right 10.x.x.x IP number. I don't know if that helped or not. -e On Thu, 24 Jul 2003, Erin Dalzell wrote: Hi there, We have just discovered that our tomcat web app is not working correctly behind a NAT.

Re: buiding 4.24
Hi, For the JK2 connector you should use the 2.0.2 source. Then compile with: ./configure --with-apxs2=/path/to/apxs then make then mod_jk2.so should be in down in the build directory. You need to manually copy the file to the apache modules directory. The complete step by step is in the archives. But that's the long and short of it. -e On Thu, 24 Jul 2003, Simon Pabst wrote: hmm weird, mod_jk2.so should be there after a successful make with no errors, what connector source release did you download? What was your jk2 configure? If you used --with-apache2 instead of --with-apxs2 then mod_jk2 won't be built as .so but instead as static module into httpd core.

Re: need a working mod_jk2 for RH Apache 2.0.40
I think one way is to remove the rpm from redhat and install the httpd server from apache.org and not use package management . But I was hoping to avoid if I can . That's the best thing you can do. -e - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

There is space required for code, data space used by the JIT, plus any memory malloced by native code drivers associated with the application running in the JVM. So the overall memory picture for Java applications turns out to be more complex than just the -Xmx value. -- Dave I have no idea, but based on past experience, if you are using more RAM than you've allocated, then you have a swap situation. If the max setting wasn't an actual max, and you could blow past it whenever you needed it, why on earth would you need it in the first place?

Can the thread stack (specified using -Xss, which we're not using) be taking up the remaining 75MB? We have about 40 threads started right now. Like I said, I don't know enough about java's memory allocation, but I didn't think that the -Xmx set the maximum allowable total memory for the JVM. Am I mistaken? Even if memory were a problem, which it may be, would that account for a 20 second delay between serving a page and closing the connection?

In the hello.jsp, the results of the page return instantly to the browser, but then it's as if tomcat just won't close the connection to the browser. The page is there, fully rendered, but just sits there waiting for the server to tell it it is done. Is there some way that the tomcat connections could be failing to terminate properly?

Start java with -verbose:gc and look in tomcat/logs/catalina.out for Garbage Collections. (set Environment Variables JAVA_OPTS or CATALINA_OPTS in bin/catalina.sh to do this in Tomcat) Try using a bigger Heapsize (though if you've got a Memory Leak that will only delay your problem) or set initial Heapsize to same as maximum, for example 128MB: -Xmx128m -Xms128m Modify the Connector you are using to access Tomcat (in tomcat/conf/server.xml) and try using more Tomcat Processors (maxProcessors=XX) or a bigger accept queue length (acceptCount=XX) (test value for acceptCount: at least concurrent users x 3) Try using another method of garbage collection, if you're using JDK 1.4.1 i'd try either ConcurrentGC with ParNewGC (ParNewGC on Multi-CPU machines): -XX:+UseConcMarkSweepGC -XX:+UseParNewGC or ParallelGC with AdaptiveSizePolicy (saves you the work of Java Heap usage analyzing :-) : -XX:UseParallelGC -XX:+UseAdaptiveSizePolicy A good article on GC can be found here: http://wireless.java.sun.com/midp/articles/garbagecollection2/ At 18:04 11.07.2003 +, you

Re: JK2
Hi, I use unix sockets when both apache and tomcat are on the same server because they are fast. Although before I install it I always ask myself if they are on the same box do I need to run Apache at all? If you aren't using any of the tricked out features of Apache you would be better off just having tomcat listen on port 80. If they are on seperate machines I use TCP sockets.
