AW: List traffic et al
i agree 100%. i think a _good_ thing would be to include these guidelines in the confirmation message one receives after subscribing to the list. this is the way how it's done eg. on sun-managers, they post the guidelines once a month. it's the most disciplined list i know. -nico Rather let all of us try to reduce volume(both in size and number), it does not require much effort. Lets just try to follow the following. [snip]
URGENT plz help (resend re: jk_uri_worker prob)
hi list i tried to find an answer to this everywhere but no luck ... my mod_jk log is full with these two entries: [jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter [jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters any idea what could be causing this?? i get thousands of entries like this, nothing else, no errors in the application whatsoever i'd really like to know what the problem here is. and if it's nothing serious, i'd like to turn these messages off as it makes everything else very hard to find, and the mod_jk.log gets bigger and bigger. many thanks, Nico

AW: TOMCAT SUCKS // what lb problem? plz clarify
3. The integration with apache (using mod_jk) sucks. It slows down the productivity of the web server with at least 1000% ?? i'm running a fairly complex website (very drastic flash frontend/java backend) and it works fine. big server though, but it really runs quite fine. I really think that TOMCAT is OK for testing purposes. Trust me - for complex configurations it sucks. well i don't do virtual hosting but it's still a fairly complex site, and i think TC goes way beyond 'testing purpose only'. in fact all problems i run in unto now were our own bugs :) can you tell us what your load balancing problems were exactly? i had it a short while behind a LB and it worked fine. currently it's back to one machine, but i'll have it LB'ed again when the load will dramatically rise in 2 weeks or so. therefore i'd be very much interested in knowing what kind of problems you were/are experiencing. thanks, Nico
AW: tomcat on a home machine???
Thus it will be impossible to resolve a domain name to the IP address of your server from the public internet, as it will change every time you dial. yes, it is possible with services like http://www.dyndns.com. -nico
URGENT jk_connect.c problem / UPDATE: weird log entry in mod_jk.log other problems
hi again i have some strange entries in my mod_jk.log, generated almost every minute: [jk_connect.c (143)]: jk_open_socket, connect() failed errno = 111 [jk_ajp12_worker.c (152)]: In jk_endpoint_t::service, Error sd = -1 [jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter [jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters does anyone here have an idea what the problem could be?? we don't have these errors on the test server, but the production machine generates them every minute. i don't see anything that would misbehave, but it sure scares me not to know what is happening here. in addition, tomcat occasionally dies with a # An unexpected exception has been detected in native code outside the VM. # Program counter=0xblahblah (don't have the exact code anymore) # # Problematic Thread: prio=1 tid=0xblaah nid=0xblah runnable (don't have the exact codes anymore) # Abort this is fixed, it was a strange problem with oro-regex that we can reproduce only on the production server (unfortunately). when oro (perl5 matcher) was fed with a control character (\u-\u001f) it died and took tomcat with it (stack overflow). bad! i'm running a 2.2.16 linux kernel, 4-cpu box, tomcat 3.2.2, apache 1.3.19, mysql Ver 11.15 Distrib 3.23.38, oro-2.0.2, jdk1.3.0_02, many thanks Nico Wieland
weird log entry in mod_jk.log other problems
hi list i have some strange entries in my mod_jk.log, generated almost every minute: [jk_connect.c (143)]: jk_open_socket, connect() failed errno = 111 [jk_ajp12_worker.c (152)]: In jk_endpoint_t::service, Error sd = -1 [jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter [jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters in addition, tomcat occasionally dies with a # An unexpected exception has been detected in native code outside the VM. # Program counter=0xblahblah (don't have the exact code anymore) # # Problematic Thread: prio=1 tid=0xblaah nid=0xblah runnable (don't have the exact codes anymore) # Abort i don't know if the two issues are related. i had the 'unexpected exception' because of a bug in oro, but we have a working workaround for that. problem still appears from time to time though, but at another place. questions: what do the first errors (in mod_jk.log) mean? couldn't find any hint on the web. what does the second error mean exactly? any ideas for a fix, or how to track down the problem(s)? any ideas where to setup logging so that this 'unexpected exception' can be tracked down? i'm running a 2.2.16 linux kernel, 4-cpu box, tomcat 3.2.2, apache 1.3.19, mysql Ver 11.15 Distrib 3.23.38, oro-2.0.2, jdk1.3.0_02, many thanks Nico Wieland
AW: Apache not talking to Tomcat on port 8007? I need a rubber room...
WTF is wrong? How can I test whether port 8007 is really open and nc localhost 8007 or a portscan or netstat -a hth, nico
AW: How is your knowledge on TomCat??????
hi magnus i have no knowledge of novell at all but just searched the archive of this mailing list and found the following. all list - sorry for posting it again, but i felt it was seemed necessary, as there seem to be lots of netware folks who have probs w/ tomcat. regards, -nico (mailing list archive: http://www.mail-archive.com/ ;) == Can you, or anyone provide setup/installation information? Thanks -jim Yes. Mikko Peltonen wrote the following instructions at devforums.novell.com. They have worked for me. But, first of all, download the JVM from Novell. Cristian Ramos Prange () Subject: Re: Info on Jakarta/Tomcat port to Netware Date: Fri, 1 Dec 2000 11:56:13 +0200 From: Mikko Peltonen [EMAIL PROTECTED] Organization: Another Netscape Collabra Server User Newsgroups: novell.devsup.jvm References: 1 , 2 , 3 OK. There seemed not to be any documentation concerning NetWare on the official release package of Tomcat 3.2, even though there are now compiled nlm's, so I'll try to briefly give some instructions: - Download Tomcat 3.2 (http://jakarta.apache.org/builds/tomcat/release/v3.2/bin/) and extract it to SYS volume. - Add the following lines to sys:\etc\java.cfg and restart JVM: TOMCAT_HOME=sys:\jakarta-tomcat-3.2 CLASSPATH=$CLASSPATH;$TOMCAT_HOME\lib\ant.jar CLASSPATH=$CLASSPATH;$TOMCAT_HOME\lib\jasper.jar CLASSPATH=$CLASSPATH;$TOMCAT_HOME\lib\jaxp.jar CLASSPATH=$CLASSPATH;$TOMCAT_HOME\lib\parser.jar CLASSPATH=$CLASSPATH;$TOMCAT_HOME\lib\servlet.jar CLASSPATH=$CLASSPATH;$TOMCAT_HOME\lib\webserver.jar - Create sys:\system\tomcat.ncf, and put in it line: java -Dtomcat.home=sys:/jakarta-tomcat-3.2 org.apache.tomcat.startup.Tomcat - Start Tomcat by executing the ncf file you just created At this point, you should be able to use Tomcat with the Tomcat's built-in http server, which by default listens in port 8080. Try pointing your browser to http://your-server-ip:8080/examples/. If you want to integrate with the Enterprise Server, do the following: - Copy the nsapi_rd.nlm file to sys:/jakarta-tomcat-3.2/bin -directory. This file is the nsapi plugin that handles the communications between Enterprise Server and Tomcat. By default communication is done through sockets by using the ajp12 protocol. - Disable Novell's Servlet Gateway. Go to Web Manager (https://your-server-ip:2200/), Enterprise Web Server configuration - Programs - Novell Servlet Gateway - Activate Servlet Gateway=No. Save Apply. - Edit the sys:\Novonyx\suitespot\https-SERVERNAME\config\obj.conf. Add the following lines. To the Init section, add: Init fn=load-modules funcs=jk_init,jk_service shlib=sys:/jakarta-tomcat-3.2/bin/nsapi_rd.nlm Init fn=jk_init worker_file=sys:/jakarta-tomcat-3.2/conf/workers.properties log_level=debug log_file=sys:/jakarta-tomcat-3.2/logs/nsapi.log To the NameTrans section of the default object, add: NameTrans fn=assign-name from=/servlet/* name=servlet NameTrans fn=assign-name from=/examples/* name=servlet To the end of the file, add new servlet object: Object name=servlet ObjectType fn=force-type type=text/plain Service fn=jk_service worker=ajp12 /Object - Restart Enterprise Server Now you should be able to get to Tomcat examples through Enterprise Server (http://your-server-ip/examples/). If you want to configure more contexts (URLs) for Tomcat, or want to setup Tomcat to serve only dynamic pages in its contexts, additional information can be found from file sys:\jakarta-tomcat-3.2\doc\tomcat-netscape-howto.html (sections Adding Additional Contexts and Advanced Config Configuration).
load balancing performance
hi list i'm wondering if somebody has experience with the tomcat load balancing in real life? i have set it up and it works nicely, but i want to use it for a project that will generate quite some load for a couple of days, and am not sure if it then will continue to work as it should :) anyone got some experience with this? especially regarding performance and reliability. thanks, -nico
load balancing and synchronization
hi list if i do load balancing with tomcat (w/ mod_jk), what happens if the two tomcat servers at the same time execute a synchronized method? will they know that they mustn't execute it concurrently or not? if synchronization worked only per JVM, would there be a workaround? thanks, -nico Nico Wieland NETVERTISING AGAgentur fuer zeitgerechte Kommunikation Samariterstrasse 5, CH 8032 Zuerich Telefon +41 1 267 11 11, Fax +41 1 267 11 99 mailto:[EMAIL PROTECTED] http://www.netvertising.ch
