RE: Shutting down one instance of tomcat 6 from a listener
That's it! I have a single Tomcat/JVM instance but multiple applications running on it. In fact with System.exit(1) Tomcat is not completely stopped; it is still running but it hangs. I have to kill the process to terminate it. So, how to shut down properly the current application from a 'listener' leaving the other webapps deployed into Tomcat to continue their business? I was unsuccessful looking for some source code to do so. -Original Message- From: Christopher Schultz [mailto:ch...@christopherschultz.net] Sent: mardi 9 novembre 2010 20:52 To: Tomcat Users List Subject: Re: Shutting down one instance of tomcat 6 from a listener -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Patrick, On 11/9/2010 11:36 AM, Patrick Sauts wrote: I'm sorry I'm French. No problem: we can work around language difficulties. More explanation usually helps. Multiple cores, maybe? The number of CPU cores should not affect the number of instances that you have. As when you use the manager to deploy different web applications, several war. So, it sounds like you have a single Tomcat/JVM instance but multiple applications running on it. You want to have one of your webapps check some configuration and gracefully stop if there is a problem, leaving the other webapps deployed into Tomcat to continue their business. If that's the case, then calling System.exit will certainly cause Tomcat to become unstable, where unstable means completely stopped. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkzZpk8ACgkQ9CaO5/Lv0PDIzwCeL7AFHpsLKcpNbRPprDxnPKRF yMUAoJSOfLBrIw0mvW/HlbRyKM7bl5Nj =olUO -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

RE: Absence of isapi_redirect log file
It's really difficult to troubleshoot ISAPI redirector problems. No one really seems to be able to help much when you get a problem and the logs are either unhelpful or vastly too verbose. I think that changes in IIS have dramatically complicated it and the Tomcat Docs have not kept up. In particular there's no discussion of which application pool the jakarta redirector is running as versus the default application pool for the server. I know for certain that if they don't match up, things break in mysterious and unusual ways. Unfortunately, some of these things only come up when you're dealing with real-world servers. If you have a toy server set up for testing, none of these things like Application Pools break.

Pid, On 11/11/2010 3:40 AM, Pid wrote: You could set CATALINA_PID and check that the process ID* contained in the file is active. That is one way of doing things, but Tomcat might not be healthy even though the process is running. For instance, I can imagine the following scenarios where the process would be running, but not considered healthy: 1. Database connection pool is exhausted - possibly permanently 2. Request processing thread pool is exhausted - possibly permanently 3. JVM has experienced an OOME and parts of Tomcat may be unstable That last one is very difficult to detect. ;) What I have SEEN (which means there are probably things you've seen that I haven't) is: 1) JSVC terminates. I scripted around this by having a cron job run every two minutes, doing something like: PIDLIST=`ps -h -o pid -C jsvc` if [ -z $PIDLIST]; then // re-start tomcat fi 2) The JVM terminates and jsvc re-starts itself. The problem for me is that I dynamically add/remove virtual hosts. I'm in the middle of re-working things so that a file gets included by server.xml and that file is kept up to date. I'm fighting this right now. The JVM crashes in the hotspot compiler when it tries to request 2GB of memory... I've turned it in as a bug but haven't heard anything. This particular thing started with JDK 1.6.0_21. I suppose I could go back, but the garbage collector seems to be MUCH better in 1.6.0_21 so I live with it. 3) The JVM just hangs on OOME. This could probably be caught by using a cron job with wget and if a timeout happens kill the JSVC application and then re-start it.

Context: an occasional app bug which started occurring with more frequency, under load. Couldn't track down the source easily and it was bringing the system down. Automatically restarting the server process turned out to be a bad idea, as the side-effect was that the heap dumps (also configured) got corrupted with a reasonable degree of frequency. (If you kill the JVM during heap write the dump borks, I needed the heap dumps.) I tried with a short delay, but that didn't seem to help matters. I also experienced cyclic reload failure conditions. What did work: creating a fail file, which a polling process would check for periodically restart the server when the fail file was a certain age (which managed to be 2mins). If more than 3 fail files existed, wait longer for a restart. If more than 5 existed, don't restart. External alerting systems notified me that the system was down.

Is this correct behavior of cookies
I run development on Tomcat 6.0.29 and IE 8. I need help to understand behavior of cookies. I created a new cookie and setup maxAge to 60 seconds running script setMaxAge(60). I expected this cookie to be persistent and to exist for 60 seconds. I ran this script to create the cookie Cookie newCookie = new Cookie(request.getParameter(cookiename), request.getParameter(cookievalue)); newCookie.setMaxAge(60); response.addCookie(newCookie); That is what I found: When I display maxAge by getMaxAge, I get -1, not 60 as I expected Cookie was actually alive for 60 seconds (as it was supposed to be) while a browser was opened even though getMaxAge() returned -1. Cookie was not persistent. It means when I closed all browsers and opened one again in less than 60 seconds, I found the cookie disappeared. I expected the cookie to be saved on my computer and exist after starting a browser within maximum age. Please explain this behavior of cookie.
AJP connector connectionTimeOut
Tomcat 6.0.29, HotSpot 1.6.0_21 on CentOS 5.
I had a problem recently where someone configured a standard AJP connector like
this:
Connector port=8009 connectionTimeOut=6 acceptCount=100
maxThreads=250 protocol=AJP/1.3 /
See the typo? connectionTimeOut should be connectionTimeout. Normally
Tomcat complains when you have bogus properties, e.g.:
WARNING org.apache.tomcat.util.digester.SetPropertiesRule.begin
[SetPropertiesRule]{Server/Listener} Setting property 'aasdfhgakjs' to '1' did
not find a matching property.
But for connectors, it's silently ignored. And for an AJP connector, with no
connectionTimeout set, the default is never to timeout. Which might not be a
problem usually, but a firewall was randomly dropping connections and the
threads holding a connection were sitting there waiting forever. Eventually the
thread pool would run out and the server stopped responding to AJP requests.
Three questions:
1) Why doesn't Tomcat complain about setting bogus connector properties?
2) Why is the default connectionTimeout (and thus keepaliveTimeout) on an AJP
connector forever? Combined with (1) this seems like an accident waiting to
happen.
3) AFAICS none of the docs on tomcat.apache.org mention that properties are
case-sensitive. I guess it's kind of obvious, but... shouldn't it be stated
somewhere?
Bonus question: should any/all of these be considered bugs?

AJP connections are intended to persistent.

Maybe. The configuration is via XML and XML is case sensitive. Seems
like stating the obvious to me. Also, not sure where such a statement
should be put. As always, patches welcome...
Bonus question: should any/all of these be considered bugs?
1. No. Valid configuration properties are correctly documented. It may
be possible to enhance the BIO connector to log a warning.
2. No. This is by design.
3. No.
1 and 3 are possible enhancement requests. Enhancement requests should
be entered in Bugzilla. Enhancement requests that include patches are
more likely to get applied.

Yes: hundreds of MBs of buffers for each webapp instance that is not cleanly undeployed can certainly bust your heap.

So far, these are my conclutions: - Very often, when I restart/redeploy my app, some garbage is left in the memory. I don't know why, given that my code closes everything (relationships with the database, etc), unloads the JDBC drivers, etc. Now I'm restarting Tomcat very often, instead of just restarting/deploying my app. The above is certainly compounding the issues below... - The Tag bodies made some buffers to grow to huge objects. I have told Tomcat to decrease those buffers if they get bigger than the standard size (512 bytes), and now the problem seems to be gone! I wonder why isn't that LIMIT=true directive a standard. I bet millions of sites are having the same problem, and they don't even imagine what a memory profiler is, and how this can be happening. This problem was swallowing hundreds of MB! Yes: hundreds of MBs of buffers for each webapp instance that is not cleanly undeployed can certainly bust your heap. I'm not entirely sure how Tomcat expects to free all those buffers (or simply relies on GC), but it's certainly possible that retaining some reference to a webapp-loaded object ends up keeping those buffers around forever, unable to free them. mmm OK, this is what I have understood so far: - The tag body buffers are stored in a growing array of chars. There is a pointer that know which of the chars is the last one being used. Initially, they are 512 chars, but if a bigger buffer is needed, the quantity of chars increases. But it never decreases. So if at one instant 1 million of chars are needed, the array will grow for that, but will never shrink even if the next use of the buffer is for a 10 characters value (I'm assuming that there is a pool of buffers to reuse, that the buffers are part of a pool). - Some some reason (I don't know why), sometimes Tomcat thinks that needs a huge buffer, so it makes the array to increase to millions of chars. I have no such big pages in my site, so I can't understand how can that happen, but it does. Then, the buffer stays with millions of chars, so the object uses millions of bytes. Do you think a leak has something to do with that? - I think Tomcat doesn't even expect to free those buffers as you say, but use them again and again instead, cause I THINK (correct me if I'm wrong) that they belong to a pool. So they just say like that forever. - Now that I set the flag, everytime Tomcat decides to empty the content of the buffer so it will be used again (emtpy=set the lastUsedCharPointer to cero), it sets it to a new array of 512 bytes if it was bigger that that. I don't know if this issue is retaled to the other one (leaks at undeployment). That isn't a standard option because in (most?) cases where the buffers are being constantly used, the performance increase is significant. Since your webapp is both misbehaving and being re-loaded often, you must use this workaround. Well, I don't know how can Tomcat think that a 8MB buffer is needed in my site for a page. That is the source of the problem. But even if its my fault somehow (leaks in my code), or just the planets aligned so this will happen, I think Tomcat should always think If the buffer got too big when I clear it, I will make it again to be 512 bytes. That just means creating a new array of chars. How much cost would that be?

Well, given that I have about 20 WARs, these caches were using about 200MB of ram. Even if my app never leaks when redeploying and doesn't degenerate, or even if I would never stop my app, I don't like to spend 200MB in these caches. I could also limit the size of the caches, but I started trying to disable them, and my site still runs pretty fast without these caches now.

Maybe my question sounded too vague and repetitive. What I meant is something like this Is the a class loader (or something like that) than I should start analyzing? I mean, is there a route I should follow in order to see which objects are stucked? If the Tomcat Manager knows that something got stucked in the memory, how does it know that?

RE: Tomcat 6.0.29 using more and more RAM until it collapses?
Well, I am using the valve indeed! I will check if it is showing the size of the responses. I guess I can find the huge pages easily there. I'm not using the trimSpaces flag. If I find it, I wont need to limit the buffer. That would be more elegant than having to do it. :-) But the other issue is that I still have to find the reason of the leak. I'm exploring YourKit for that. I guess I will find how to do it soon. -Original Message- From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Sent: Tuesday, November 16, 2010 12:00 AM To: Tomcat Users List Subject: RE: Tomcat 6.0.29 using more and more RAM until it collapses?

Re: Any tools to detect tomcat services failure, and start it again automatically?
Thanks everyone, I simplify the problem with my own request. In our real env, only one application deployed in one apache-tomcat server. And application will always have its name under opt folder as: /opt/tomcat/APP_NAME/tomcat-VERSION/webapp/APP_NAME tomcat version: 5.5, 6.0.18, 6.0.29 Unix env:Solaris 8/10 I wrote a small script to detect the application status easily. $ cat tomcat_status instance=$1 status=$(/usr/ucb/ps -auwwwx |nawk '$1=$1' OFS=\n |nawk -F \/ -v s=$instance '/Dcatalina.home=/($4==s)') if [[ $status == ]]; then echo Application $instance is NOT running. exit 0 else echo Application $instance is running. exit 1 fi With that, I can detect the exit ID in cronjob, if find any application is not running, the cronjob will try to start it. This simple script has fixed my current problem, I will think to write another script, which will detect the application service status by error logs. Happy to share it to everyone, if you have any question regarding this script, just ask.

the tomcat encoding
hi all: I wrote an app and there are some chinese content, and there are some code like this str = new String(chineseContentString.getBytes(iso-8859-1), utf-8); the app runs pretty well in the tomcat of my pc. however ,when it was deployed in other machine. all the Chinese content becomes messy code. so ,does anyone know how to got to encoding of the tomcat. or it was just iso-8859-1 and cannot be changed? thanks by the way , the edition is 6.0.20
