Re: Tomcat cluster serving ~50 lines of the page when a request hits a stopped webapp for the first time
Rainer, Thanks for that. Yes we are going for a mix of both really. But I'll run some bench marks against both sticky and none sticky to see how it gets on.

DLL files for connecting Apache Httpd and Tomcat
Hi, I am hosting multiple sites on one Windows 2003 box using Apache 2.2.4 The sites are all built on Joomla 1.4 and therefore I have PHP 5.2.1 and MySql installed. Everything works fine. I also have Tomcat 5.5 installed and running happily on port 8080. I now have need to build a site using JSP/servlets but naturally I need to pass the requests for JSPs through the webserver to Tomcat as I want access to the site through port 80. I have done this before a few years ago but now I can not find the required mod_jk2- 2.43.dll The official Apache binary download page at http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.23/ purports to being for Win32 but other than the ISAPI_redirect DLL files the rest are .so files for UNIX/linux. Is this an oversight on Apache's part? I would really appreciate help on getting this issue sorted. I know it can be done but I can not find the correct files anywhere and I don't fancy building from source. As a follow up to the original question: could a link the Apache httpd server with the Tomcat container in Glassfish? I would ideally like to have a full J2EE server. Many thanks Hugh Acland

Re: DLL files for connecting Apache Httpd and Tomcat
Hi Hugh, - jk2 has been deprecated a long time ago. Please use jk, which is fully supported and now contains most of the features, that were created for jk2 - the *.so files in the download directory for win32/win64 are actually windows libraries. You can use them. Only there name is a little misleading. - we released 1.2.24 some minutes ago. You might consider using this version instead of 1.2.23. - yes in principle you can use JK with glassfish, there are some blogs about what to do on the app server side. Search the web for ajp or ajp13 and glassfish. On the web server side in general everything works the same as for Tomcat. The web container inside glassfish is a fork of Tomcat. So not all fixes for the AJP connector of Tomcat might be included with glassfish. Fixes during the last year include support for bigger AJP packets (needed e.g. probably when using client certificates ot using very huge http headers) and support for up- and downloads bigger than 2 GB.

FW: Quesion on starting tomcat (as a windows service) from Ant
Obviously you should try to figure out who is using that file.
But if you want to do it like old days.. Do this in your ANT
property name=service value=Tomcat5/
target name=stop description=Stops the ${service}
exec executable=cmd.exe
arg line=/C net stop ${service}/
/exec
/target
target name=start description=Starts the ${service}
exec executable=cmd.exe
arg line=/C net start ${service}/
/exec
/target
If is linux you will do a service start tomcatd or service stop tomcatd

Subject: RE: Quesion on starting tomcat (as a windows service) from Ant
Rodrigo
Thanks for the feedback. As it works out, when I drop the war into
\webapps, tomcat partially deletes the previous version in the
directory below webapps and then can't proceed. The problem is
log4j.properties is being used by another (at this point unknown) app
(definitely not one of mine). The end result is Tomcat remains running
with a partially deleted web app and no way to deploy that app. The only
way to fix the problem is to stop tomcat delete the offending web app's
directory tree and restart tomcat.
The windows services version of tomcat is controlled by Procrun whic is
not usable by Ant; forcing me to use a manual process. If you know how
to stop the WinXP Services version of tomcat from a command prompt, I'd
appreciate hearing about it.
I realize that in the liong run the best thing to do is to find out what
other program is holding a reference to log4j.properties, but that will
be a difficult job, since other than tomcat and procrun no other java
programs are running, as far as I can tell.
Thanks and please reply if you have any additional advice.

Re: DLL files for connecting Apache Httpd and Tomcat
Hi Hugh, jk autoconf is broken for quite some time now. You can use mod_jk without autoconf, but you will need a little time to setup the config. There are a couple of descriptions concerning configuration in the JK docs. We might repair autoconf some time, but you shouldn't really use it at the moment. It's not only a question of making it spit out a configuration, but also about how good this configuration is. The core feature of autoconf was, that it knows, which contexts are deployed in Tomcat, so it can set up JkMount directives. Also it knows, which port the AJP connector listens to. Both things can be really easily setup by hand. As a starter, read http://tomcat.apache.org/connectors-doc/generic_howto/quick.html and when it works, go deeper into the documentation to read more about better production settings.

Re: Tomcat with 8 GB memory
I think what we're seeing here is the reason for the oft-heard, seldom-heeded advice that the only benchmark which means anything is *your application*. Once you see how the code you care about performs, *then* you can bum a few cycles here and there to tune it up. Generalities such as 64-bit machines are faster/slower really don't say much outside the context of a specific application. -- Mark H.

Encoding/Decoding
This test page results are shown:
Latin Character input Capital A with Circumflex ^: Â
Greek Character input Omega: Ù
without decode=Latin%3A+%C3%82+Greek%3A+%C3%99
with decode=Latin: Â Greek: Ù
It appears the encoding is set to IS0 8859-1 since the character encoding maps
correctly to that character set.
Here are my server.xml settings:
Connector port=8009 URIEncoding=UTF-8 useBodyEncodingForURI=true
enableLookups=false redirectPort=8443 debug=1
protocol=AJP/1.3 /
Connector port=8080 URIEncoding=UTF-8 useBodyEncodingForURI=true
maxThreads=150 minSpareThreads=25 maxSpareThreads=75
enableLookups=false redirectPort=8443 acceptCount=100
debug=8 connectionTimeout=2
disableUploadTimeout=true /
Any ideas what I am doing wrong would be greatly appreciated.

Is length 1090 correct?`So does the full body have that length? Yes firefox reports that the page is 1k in size, via the web developer's tool bar. I have seen it happen in IE 6 and 7 also.

Recovery from OutOfMemoryError?
Our Tomcat-based app suffers from occasional OutOfMemoryErrors. We have found that we need to manually restart Tomcat when these happen; frequently the Tomcat process appears to be working after the error, but is actually crippled in one way or another by the loss of some key thread. We would very much like to trigger an automated Tomcat restart when an OOME occurs. Does anyone have suggestions on the cleanest, safest way to arrange this?

Fixing the bug would be cool, but the bug is actually just too many users contending for the same heap space, so that's going to be tough. I'd thought of the log watcher, but that seems a rather blunt instrument; I was thinking there might be some kind of Tomcat (or JVM) intrinsic mechanism for this. -Original Message- From: Leon Rosenberg [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 31, 2007 9:46 AM To: Tomcat Users List Subject: Re: Recovery from OutOfMemoryError? variant 1: a log watcher that checks for OOMe and restarts tomcat variant 2: fix the bug :-) regards Leon On 7/31/07, Craig Berry [EMAIL PROTECTED] wrote: Our Tomcat-based app suffers from occasional OutOfMemoryErrors.

Re: Recovery from OutOfMemoryError?
1. you may have a memory leak in your code... do some profiling 2. check out abandoned sessions that are due to expire perhaps you can lower the session timeout and that will make some memory available earlier.

RE: Recovery from OutOfMemoryError?
Oh, I'm not blaming either one. Normally, our server is quite adequate to handle the expected user load. Every now and then we get a perfect storm of too many users asking for too many large-memory requests, and an OOME happens. We're investigating ways to increase capacity, but in the mean time, automating recovery would help keep the 3am phone calls from happening. We're running Java 6 and Tomcat 6. It's definitely heap space that's running out, and we're actively profiling various load scenarios to spot the most likely targets for memory-use reduction. But again, a short-term technique to automate the restart would help a lot. -Original Message- From: Caldarale, Charles R [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 31, 2007 10:00 AM To: Tomcat Users List Subject: RE: Recovery from OutOfMemoryError?

RE: Recovery from OutOfMemoryError?
The trouble is that our memory demand per user session is unpredictable. Some user sessions do things that barely touch the heap; other sessions can make huge demands. It depends on what the user chooses to do during the session. So throttling user count down to make it utterly safe would be impractical. Instead, statistically, it's unlikely that more than one or two memory-hungry sessions will be active at any given time. When we get more than that at once, we risk an OOME. -Original Message- From: Andrew Miehs [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 31, 2007 10:01 AM To: Tomcat Users List Subject: Re: Recovery from OutOfMemoryError?

Re: Recovery from OutOfMemoryError?
hi Craig, if you get OutOfMemoryError reliably in your log, you might consider the tanukisoftware Java Service Wrapper as an intermediate solution. It can watch the output and automatically restart Tomcat. I would not combine it with an app, that has a very high volume of log output though. Also I think, the output must go throw STDOUT, so if the error occurs in different log files, you have to throw all those together to stdout. Of course with log frameworks you can define stdout as an additional log target. Setting this service wrapper up will take you some time, but it's a very powerful wrapper. Java 6 has -XX:OnOutOfMemoryError=cmd1 args...;cmd2 ... which could also be useful (sending mail etc.). I don't really know how reliable it is, but setup is definitely faster than the service wrapper. If this works, report it back,, it might be useful for others as well. Be careful when designing cmd and args about assumptions concerning current working directory and environment.

Re: Recovery from OutOfMemoryError?
How about using SoftReference to store _large_ or some session data? It must add additional overhead due to data re-retrieval needed in case it has been collected, but at least its guaranteed that you will never get an oome, and chances are good, that you will loose inactive sessions earlier. regards leon p.s. of course only a workaround but may help if data size is unpredictable. On 7/31/07, Craig Berry [EMAIL PROTECTED] wrote: The trouble is that our memory demand per user session is unpredictable. Some user sessions do things that barely touch the heap; other sessions can make huge demands. It depends on what the user chooses to do during the session. So throttling user count down to make it utterly safe would be impractical. Instead, statistically, it's unlikely that more than one or two memory-hungry sessions will be active at any given time.

In my experience, OOMEs are not just caused by the failure of a large allocation, such as a huge array or something, but rather tons of small allocations.

I have recently changed a lot of my old perceptions on this matter after reading this excellent article: http://www.ibm.com/developerworks/java/library/j-jtp01274.html If you change your mindset when you write your apps to consider how the garbage collector actually operates, then those memory errors are less likely to come back and bite you. And on the subject of soft references, I started using them as well as transient decelerations on some objects I didn't need to persist in serializable classes and it really helps reduce the load.

Some of the stress-testing of our JVM involves running apps designed to provoke OOMEs; these readily recover and keep on truckin'. The OP would seem to corroborate this claim, since it sounds like his whole app server becomes unresponsive once he gets an OOME (hence the early morning phone calls). The supposed timing of the phone calls leaves me somewhat skeptical; what are they running where the peak load occurs at 3 AM? If your assertion (OOMEs can be ignored, since only one allocation fails and the rest of the VM is fine) were true, then the OP would not be getting any calls in the middle of the night: the user would simply re-try the request and (hopefully) get a result the second time. That's not what I said at all. Each logical module should be designed to handle such situations, typically by discarding what has been done up to the point of failure, and then returning an error to its caller. What is likely to have happened instead in the OP's case is that the app encountering the OOME had no provision at all for error recovery, and simply quit, leaving many now useless objects around with live references to them. It may have even made matters worse by trying to generate an error message of some sort. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
