Re: Directed Load Balancing with Sticky Sessions
On 21.04.2009 07:48, Mike Duffy wrote: I've read through the load balancing info in the docs: Using Apache HTTP Server 2.x with mod_proxy What I would like to do is have users sign in on one server and then, based on geographic characteristics, redirect them to another server. If I simply use the method sendRedirect(String location) from HttpServletResponse will the redirected users have a sticky sessions on the server I am redirecting them to? We have a large base of geographically dispersed users. Our data base is a far greater bottleneck than our application servers. Our plan is to geographically segment the data base and then match a Tomcat server to a data base. Any suggestions? Geographic balancing via redirects will only work, if the different locations use different server *names*. Otherwise any redirect URL will point to the same server name, and since the client already resolved the address, the request will be send to the same server IP. Geo-based redirects can be done e.g. with Apache using GeoIP. They have a free geo database. The commercial one is a bit better, but the free one is not to bad. If you need to use the same server name for all locations, you need to make the geographic balancing in the DNS layer. The third possibility is, that you only want to geographically distribute the Tomcat layer and not the Apache layer. This is not very likely, because then you will of course need a very good global internal network between the Apaches and the distributed Tomcats. If you have reasons for this concept, you could do this again with GeoIP and either mod_proxy or mod_jk.

Problem with maximum threads
Hi, I am using Tomcat 6.0.9 with the following server.xml config file: The Java version I am using is JDK1.6.0_06. The problem is with the tomcat web app being used for a load test at 200 messages/sec. The application runs well enough for half an hour but after that time, the CPU consumption is maximum and idle is 0. Also, there are more than 1000 threads even if I have configured the maximum threads to be 70 in the configuration. There is no problem in the application code. Where can be the problem in the Tomcat?

RE: Problem with maximum threads
From: connossieur [mailto:anand.b...@aricent.com] The application doesn't have problems as I tested it with Visual VM (profiler for java 6) on Windows. OK. You've done more research than most, then - we get a lot of people blaming Tomcat as the first thing they do, so we tend to have some well-developed check your code! reflexes. Anyways, can there be problem with Tomcat? It's pretty stable. But no code is ever 100% guaranteed bug-free, despite what we might like, so there always *can* be a problem :-). 6.0.9 is quite old now; the current version is 6.0.18, and there have been a number of bugfixes. How tied are you to the old version - can you update and see whether that resolves the issue? I mean, I have limited the number of threads, still tomcat spawns more than 1000 threads? This is where that thread dump comes in. *Something* is spawning threads - rather than guess what's doing it, let's get some evidence of what they're doing?

When I look under webapps I see that my exploded application directory is still there and if I look inside of the directory everything has been deleted except for 6 .jar files under WEB-INF/lib (adf_faces_impl, afc, custComps, jsf-impl, log4j-1.2.8, and portlet-client-adf). All other .jar files under lib are gone. Since this does not get deleted I cannot redeploy the same application. Any suggestions? I'm using Tomcat 5.5 and I'm creating my .war file from JDeveloper.

Re: Undeploy does not delete all .jar files
I'm trying to undeploy my application in Tomcat without having to stop and start the Tomcat service. In the manager I undeploy the application. When I look under webapps I see that my exploded application directory is still there and if I look inside of the directory everything has been deleted except for 6 .jar files under WEB-INF/lib (adf_faces_impl, afc, custComps, jsf-impl, log4j-1.2.8, and portlet-client-adf). All other .jar files under lib are gone. Since this does not get deleted I cannot redeploy the same application. Any suggestions? I'm using Tomcat 5.5 and I'm creating my .war file from JDeveloper.

FWIW, we've discovered that replacing NIO with the old blocking connector improved latency by a factor of 4-5 times. Digging deeper... Definitely something to look into. NIO uses some OS black magic that might not be visible to your Java profiler. Perhaps use a native profiler to see what's going on?

As regarding the admin section, you can filter it using apache access control. I agree, load balancing seems to be not related to the question. One first decision would be, whether you are able to deploy your application twice, once as the ROOT context and once as admin. Then everything will become obvious. If you only want to deploy it once, e.g. as admin, then you will need to do URL rewriting in the Apache-Layer.

All of my messages are printing twice in the logfile.
Application log messages or Tomcat log messages? Are you using log4j
only in your application or are you also using log4j for server logging?
Can you give us an example of a repeated log message?

Hello:
I am using Netbeans 6.5 IDE to deploy to Tomcat 4.1 server. This Tomcat
server cannot be registered with the Netbeans tool as it is an older version

I follow the instructions and try to start the Tomcat server from the IDE

How can I fix this problem, so that I can start the Tomcat 4.1 server?

Since you put it that way, how much you payin'? Besides,
-Dsun.io. is not an error. It's at best a command line option to
the JVM.

Apache Tomcat 503 errors
Hello, I posted this on the Apache list a while back and didn't get any response. I'm running Fedora Core 5, httpd-2.2.2-1.2 (worker MPM), Tomcat 5.5.17, Java jdk1.5.0_07. I have about 40 connections/apps from Apache to Tomcat like so: ProxyPass /foo ajp://localhost:8009/foo/ I am getting a fair amount of 503 errors. Logs look like this: Tomcat catalina.out Mar 29, 2009 1:35:23 PM org.apache.jk.core.MsgContext action WARNING: Error sending end packet java.net.SocketException: Broken pipe Apache ssl_access xxx.xxx.xxx.102 - - [29/Mar/2009:13:35:18 -0400] POST /foo/bar HTTP/1.1 503 40920 Apache ssl_error [Sun Mar 29 13:35:22 2009] [error] [client xxx.xxx.xxx.102] proxy: error processing body, referer: https://foo.bar.com/foo/bar [Sun Mar 29 13:35:22 2009] [error] proxy: got bad response (5) from 127.0.0.1:8009 (localhost) The times are not exact matches but the pattern is consistent. I don't know if this is a Tomcat problem or Apache/mod_proxy. Many requests are GET - not all POST. The client hasn't complained about specifically seeing the 503 error, it could be hidden or messing things up in some other way (like my AJAX backend). Can anyone give me some guidance here? Googling the log entries does't amount to much. The feedback on java.net.SocketException: Broken pipe seems to be that it's harmless, but it does coincide with Apache errors and ultimately 503, so I don't think it's a simple case of the user hitting the stop button. Is there a preferred alternative to connecting Apache and Tomcat? Or is mod_proxy the best? Thanks for the help. P.S. I know the system is old, and you might be inclined to tell me to upgrade but I don't have that option at the moment. Any ideas on what to explore would be helpful. -- Daryl Stultz _ 6 Degrees Software and Consulting, Inc. http://www.6degrees.com mailto:da...@6degrees.com

Subject: RE: Deploying to Tomcat Server
Yes this is most certainly a tomcat/ant issue - probably a tomcat issue -
something in startup.bat since you say that you cannot even run the ide using
startup.bat Looks like a misplaced quote someplace in the bat file.
Good luck,

Subject: Deploying to Tomcat Server
Hello:
I am using Netbeans 6.5 IDE to deploy to Tomcat 4.1 server. This Tomcat
server cannot be registered with the Netbeans tool as it is an older version
of Tomcat.
I follow the instructions and try to start the Tomcat server from the IDE
[see syntax below]. If I run it from the IDE or simply run the startup.bat
file I get the following error:-
-Dsun.io.useCanonCaches=false
How can I fix this problem, so that I can start the Tomcat 4.1 server?
Thanks
Richard

[snip] The problem started from day one. each day across all our sites, some shoppers will randomly have their carts purged out right in the middle of their checkout process. Are all your customers using Cookies? If some people are using URL rewriting because cookies aren't supported, you might be losing the session id due to an accidentally non-encoded URL. But that would have had the same problem under Resin, so it's unlikely to be the problem. Do you ever switch hostnames during any of the website interactions? That would break your Cookie trail and you would observe the user's session disappearing. The same thing can happen if the session cookie was created using HTTPS and then you switch to HTTP. My only conclusion is somehow these customers are losing their sessions and being issued new ones. It seems to do this randomly and I can't seem to replicate the error myself, but I am recording how often it occurs to other people. Can you give us more information about the circumstances? Does it always happen during a particular page transition? What else do these failures have in common? I'm uncertain who is the culprit here (IIS or Tomcat or TomcatRedirector). It's unlikely to be IIS or the redirector... they just pass-through the session identification information to Tomcat. I have read other entries with people who have similar problems, but there doesn't seem to be much in the way of solutions. I think that's because these issues are often complex and the solutions are not very generalizable. The problem typically turns out to be the application itself or network configuration or something like that. There is no setting in Tomcat to make it stop losing your sessions (and if there were, I'm sure it would be on by default). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAknuKX4ACgkQ9CaO5/Lv0PCKnwCfdwp3UXUckpV49KjOS5wUg27s ESkAoKWLl3Dl8owc8CvyrdHGsrIz3vNB =E4s5 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Installing mod_jk 1.2.27 on NetWare 6.5 SP8
Christopher, I have received an off-line reply from Rainer Jung who suggested to discuss the issue with Gunter Knauf, the person responsible for NetWare binaries compilation. According to Rainer, The check for multiple JkWorkersFile directives in the config has been added in revision 580793, so between 1.2.25 and 1.2.26. It seems to me the mod_jk developers overlooked the NetWare specifics where the same process can run independently in different memory spaces. JkWorkersFile is instantiated once per httpd instance. There are potentially multiple instances of the same process allowed in NetWare. Apparently that causes some problem with new version of mod_jk. FYI, version 1.2.23 runs fine on the same .conf files.

Headstart on Resolving OOM-PermGen errors on webapp reload
Mark, Any chance we could make a headstart on Resolving OOM-PermGen errors on webapp reload ?? Perhaps some general pointers, guidance etc. [to help you refine the talk in advance :-) ] The manager app is giving me more more of: FAIL - Application at context path /ctx could not be started FAIL - Encountered exception java.lang.OutOfMemoryError: PermGen space This is on a Tomcat 6.0.18 (java 1.5) running on a remote Linux CentOS 5, in a Parallels VM, with httpd + mod_jk, running two versions of the app. Total memory available is 432 MB, with a number of non-system, non-TC processes, including ActiveMQ and 9 Postres processes. But there appears to be about 200MB of unused memory according to the Parallels control panel. I develop locally on a Mac OS/X 10.5.6 box with 4GBmem using (My)Eclipse and Tomcat 6.0.18 directly. With lots lots of reloads, I'm not surprised that I eventually hit OOM PermGen space in this setting, but it happens much less often than on the CentOS box (of course 4GB != 432MB). Thanks...Ken Mark Thomas wrote: I was at a conference recently and rather rashly made the statement OOM PermGen errors on reload are an application issue, not a Tomcat one.

RE: Headstart on Resolving OOM-PermGen errors on webapp reload
Hi Ken (and Mark), Different Mark here... I'm new to this mailing list and am not a Tomcat developer. Forgive me if I'm interrupting your thread, but I am very interested in this topic, since I've spent a fair amount of time debugging OOM-PermGen errors within Tomcat (5.5.x). I would be interested in hearing any tips or tricks regarding OM-PermGen, too, and am happy to share my experiences regarding this. None of the issues I've looked into have never been attributed to Tomcat. They have all been application issues related to an inability to garbage collect a webapp's classloader. This root causes were split between one of the following: * A webapp registering an object with another object that outlives the webapp and forgetting to unregister it webapp shutdown. As a result, that object cannot be garbage collected, which also prevents that webapp's classloader from being garbage collected. Examples of things that outlive a webapp or objects from libraries within Tomcat's shared library folder, Tomcat itself, and the JRE itself. For example, if a webapp registers a JDBC driver or a JCA/JCE provider, it should take care to unregister it on shutdown. * Instantiating a new Thread somehow (e.g. directly via its constructor, or indirectly via a thread pool, a Timer, or a ScheduledExecutorService) in response to a request to a webapp. This is because, by default, the new Thread inherits the parent thread's context classloader, which in Tomcat (5.5.x) is set to that webapp's classloader. If that Thread keeps the context classloader reference and outlives the webapp, the webapp's classloader cannot be garbage collected. As an aside, those causes highlight a reason why people should be weary of putting a new JAR files into one of Tomcat's shared library folders. Doing so requires that a webapp be vigilant about cleaning up any interactions with that library on shutdown. Said library also needs to provide a means to do the cleanup, as well as be sensitive to context classloader issues. When trying to debug these issues, I typically load things up in a profiler, stop the webapp and see of its classloader still resides in memory. When it exists, I use the profiler's find the garbage collection root to help determine why the classloader still resides in memory and figure out how to fix the issue. If using JProfiler (and probably other profilers), I think you have to tell it to go not stop when it reaches the Class object along the reference path. To help pro-actively detect webapp classloader garbage collection issues, I've leveraged the Insane library (a library I found from Netbeans while researching the topic) to write a utility that searches for webapp classloaders that should have been garbage collected. Using the utility in combination with automated tests has been definitely helped catch and diagnose issues. Apologies if this wasn't helpful. Please let me know if I'm wrong, outdated, or if there is a better way!

Re: Deploying to Tomcat Server
Richard, Considering your later comment about you doing this for free, I apologise for my earlier jibe. My guess : you simply have a CR or a quote misplaced in your startup.bat file. This can be the result of a variable value being inserted, maybe by another script which calls startup.bat. Add some echo statements around the place where you see a command using, for example, JAVA_OPTS.

With lots lots of reloads, I'm not surprised that I eventually hit OOM PermGen space in this setting, but it happens much less often than on the CentOS box (of course 4GB != 432MB). Can you observe your heap and which ClassLoaders are still hanging around? You might want to check to see how many org/apache/catalina/loader/WebappClassLoader objects are still live. In my web application, just after a Tomcat startup, I have 2 instances of this class, both of which are live. After an application reload, I can see that I still have 2 live WebappClassLoaders: one of them is the same one that was live before the app reload (probably the Shared webapp ClassLoader - I'm using TC 5.5) and the other one is a new one that appears to have replaced the old one (which should be expected, since the old one should be discarded after the undeploy). If you find multiple WebappClassLoader objects still hanging around, you can probably start looking for the objects they actually own. Those will give you a clue as to what services or objects aren't being cleaned-up correctly when your application shuts down. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAknuPiUACgkQ9CaO5/Lv0PBZ9gCgwnO0rP3j40m32+vI1jmy0qaI 9w0AoMCt+AteT1uv+vvrgCbpteNV9rGb =X9YG -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
