Re: access symbolic link
So how do you point to content outside of a war? I have the same problem with 5.0.28 pointing to static content outside of a war. Even a symlink included in the war (and setting "followsymlinks="true" in the context) does not work.

Re: 64 Bit Machines and Tomcat
The one caveat I have seen is when you use third-party software that is compiled; chances are it was compiled with 32-bit system libraries and will not take advantage of the 64-bit data structure. If you can, spend the time compiling the third-paty software using 64-bit JDK.

Bug in "allowlinking" on AIX?
I am definitely having an issue getting "allowlinking=true" to work in a Tomcat 5.0.28, JDK 1.4 on AIX 5.2 install. I have tried multiple scenarios using the following tag: I can bring up the app but a request to "/help", which is a symlink in the war to a directory outside of the tomcat applications directory, throws 404s. I also tried this: I changed to appbase to go to a webapps which is empty so I knew the context was definitely loading the unpacked war which includes the symlink. I still get a 404. The ChangeNotes for the 5.0.28 version states explicitely: --- Symlinking static resources: --- By default, Unix symlinks will not work when used in a web application to link resources located outside the web application root directory. This behavior is optional, and the "allowLinking" flag may be used to disable the check.

Cannot get symlinks in war to work in tomcat 5.0.28
I have an app that ahs to refernce http content outiside of the war. Since there are many references to the content using URI "/context_name_for_app/help/foo.html", I cannot map the content to another context. I also did not want to have the 100s of MBs in the war. I am running Tomcat 5.0.28 with JDK 1.4 on AIX 5L. I tried to do symlinks to the content from within the war and then access the help but I get a 404. So I added an explicit context to allow symlinks: I can get to the app but I cannot get the help symlink to come up. I put the symlink called "help" in the top level of the war file. I can cd into the link and it goes to the right directory. All of the files are readable to the world.

Re: How to Configure IIS/Tomcat to perform basic authentication
To answer your question, it would help to at least include the relevant OS and tomcat version information. In Tomcat, you can set a resource valvel that does the auth for you. Docs for 4.1: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.html. Docs for 5.0: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/realm-howto.html.

1.2.10 JK compile issue on AIX 5L
After 800 tries at getting APache compiled with the AIX C compiler
xlc_r, I now need to compile mod_k. I downloaded the sources for
connector 1.2.10.
I am trying to compile it on AIX 5L with uname -a "AIX hostname 2 5
00C04A2E4C00". I am using AIX's cc_r compiler per instructions from
http://people.apache.org/~trawick/tomcataix.html#mod_jk_gcc.
I think the compile is in some sort of loop. Here is the output from
truss that repeats over and over:
statx("/usr/bin/ln", 0x2FF211B8, 76, 0) = 0
link("/tmp/sh3686418.1", "/tmp/sh3686418.3671") = 0
kfork() = 3850378
_sigaction(20, 0x, 0x2FF21210) = 0
_sigaction(20, 0x2FF21210, 0x2FF21220) = 0
kwaitpid(0x2FF21280, -1, 6, 0x, 0x) = 3850378
_sigaction(20, 0x, 0x2FF21210) = 0

statx("/usr/bin/sleep", 0x2FF20F18, 76, 0) = 0
It creates a link in /tmp, does that kfork stuff, and then sleeps
until the next symlink. The numbers on the tmp file keep going up
(i.e., the "3671" in the "/tmp/sh3686418.foo").
Here is the make it is hanging on:

(Not sure how to look at header - I do not see any headers in the response in telnet) I put a time stamp at beginning and end of my processing. Elapsed time is 20ms. Page size < 500 b. All done locally. Browser (Internet Explorer) takes about 9s to display the XML. Page is buffered (32K, though doesn't help, autoflush on). I even tried with response.SetHeader (Connection, close) no luck. Similarly my (C++) client makes a bunch of call to such JSP pages returning XML. Each time the processing supposed to happen, happens in 20-100ms. But the client seems to be 'waiting': gaps between timestamp for next request spans more than 10-30s. The client uses Microsoft's IXMLHttpRequest (MSXML v3). Any ideas what could be happening?

Re: Can't compile mod_jk 1.2.8
Basically, the idea is that if you want to serve static content along with dynamic (i.e., Tomcat webapp generated) content, you can server the dynamic through mod_jk/Tomcat and server the static from Apache. Apache tends to be more efficient and finely tunable from the straight http side. Additionally, if you want to cluster Tomcat's, the JK module is essential. So, if you only serve dynamic content and do not need clustering, let Tomcat servr the http connections. If you need to have Tomcat on another server (due to DMZ security, etc), use mod_proxy to pass all requests from Apache to the http connector of Tomcat. Finally, if you have static content and/or need clustering, go with mod_jk. Ben Ricker On Jan 10, 2005, at 5:54 PM, Troy Simpson wrote: Parsons... How would mod_proxy() work? How is it used?

For NIC failover, I setup two Tomcats on each server bound to each NIC. So, if one NIC goes, I only lose one instance and that box can still serve some connections (and not be totally out of the running). You might also want to run multiple, different contexts to keep apps clustered in separate Tomcats for reasons of wanting a certain App to always run while not being as worried about another App running (say a QA context?).

Tomcat is probably not started or is listenning on the wrong port. > Failed errno = 111 Looks like there is a mismatch between the workers.properties and the server.xml (Tomcat's config file). The server.xml sets up Tomcat. More importantly, it sets up a Connector which opens a socket connection on a defined port (Look for the Connector' section in the Service section of the server.xml). This port is what mod_jk needs to know about in the workers.properties. Some snippets from my config: -Server.xml snippet- -End Server.xml snippet- -mod_jk's workers.properties file snippet- # # First tomcat server # worker.tomcat1.port=11009 worker.tomcat1.host=10.1.1.1 worker.tomcat1.type=ajp13 -End mod_jk's workers.properties file snippet- Check out both of these files and make sure the config is setup cporrectly. It looks like either the Connector is not configured or the workers.properties does not have the right info for the workers spawned by Apache. > All of these errors appeared at the same time I was trying to view a JSP on > a site that had "lost touch."

Re: mod_jk load balancing with multiple apache servers
I have the exact same configuration but I do not do session replication because of the fact that our app was not written correctly (something about serializing variables and ours are not serialized; it will take a code audit and rewrite to accomplish it). Anyway, here is what you can do: http://www.theserverside.com/resources/article.jsp?l=Tomcat Tomcat 5, now in development, will have session replication across Tomcats (i.e., clustering) built-in. I will say that Mr. Moliere makes a good point: sending session data across the network unencrypted is a rather large security hole. But then again, the communication between mod_jk and Tomcat is by default unencrypted. Ben Ricker Wellinx, inc.

I myself am not a programmer, so I do not know what the exact method in Java is. An easy way to figure out if it is database connections not being closed is to check the connections from the Tomcat server to the database (if you are admin) or, if you have the access, check the jdbc (or odbc) connections used on the database. There should not be more then 10; we run a DB pool of 10 to handle roughly 100k hits per day. We run an almost 100% dynamic site and those 10 connections handle the load admirably. If the number of DB connections grows, we know that either our load has grown all of a sudden or there is a DB issue. 98% of the time, it is a DB issue. We have gotten rid of the socket closure issue as the developers jobs were on the line after they audited the socket closures that caused a few production outages.

Re: Tomcat Load Balancing / Session Clustering - Tests
Well, load testing on the Apache end would be the way to go for scalability testing. You can monitor the network connections to the Tomcat instances (use of netstat does well here; grep for the number of connections to each port every N seconds or minutes, etc.). To test the session stuff, try shutting down instances as you are running through the app. Can you access each Tomcat instance individually? The best way is to use each Tomcat's web server and to access it on the port. Then, shut down that Tomcat and access another Tomcat by its port. If your session continues unaffected, you are good to go. If you have a REALLY good load tester that can capture page data (i.e., return codes and pages from the web server), you could randomly shutdown Tomcat instances while load testing to see how that affects the ouput.

Re: Number of Processes
As far as I understand it, top and ps changed in Redhat due to the
confusion of processes vs. threads. I am not positive that this is the
case, but you might just look up the CHANGE docs for the package that
supplies Redhat's ps and top (probably two different RPMs).

Slowness in Tomcat app
I am seeing a strange slowness on our QA tier. For some reason, this only occurs on this one tier (we have a production setup running, as well as a development "playground"). I have two Apaches talking to two Tomcats running on Solaris. They are running Tomcat 4.0.5. I can see no reason for the problem. Both Tomcats are up and running and listening on the correct ports. The only indication of an issue (which may or may not be related) is the following error in the mod_jk.log on the Apache side: [Wed Jul 02 10:23:34 2003] [jk_ajp_common.c (679)]: ajp_connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [Wed Jul 02 10:23:34 2003] [jk_ajp_common.c (1041)]: Error reading reply [Wed Jul 02 10:23:34 2003] [jk_ajp_common.c (1178)]: In jk_endpoint_t::service, ajp_get_reply failed in send loop 0 What does this error indicate? I am not a developer, so looking at the source code would get me no where.

Re: Tomcat security?
Plus, if one runs as a non-priviledged user account with no login privileges (i.e., locked account) and your permissions are correct, then only root and Tomcat can read the users file.

Re: clustering
You seem to be confused (or maybe it is me). You are not doing clustering. You are trying to do session replication across Tomcats. If you are not using something like Apache in the front, how will the user ever know to switch from 8000 to 8001? They will never know. Clustering is a totally different thing where you utilize special hardware and software to slave multiple servers into one virtual server which share processing among the CPUs on the servers. it is basically Multi-Processing across servers.

Re: Connection drops with tomcat-based game server (very shortversion)
One other suggestion: You might try putting Apache in front of the Tomcat to see if it still drops the connections. If the behavior stops, it might be something in the httpd connector. If the behavior persists, then I would look at the app or, more likely, the other "network" access (is there firewalls? VPN? some weird network setup?).

Re: Connection drops with tomcat-based game server (very shortversion)
Sounds like a load issue coupled with a config issue. How about some logs entries? DO you see anything in the logs you setup? Catalina.out? Context log? Also, some idea what OS and version would also be helpful. It is nearly impossible to tell (at least for me).

Re: Tomcat security concerns during start-up
I do not see this as a problem. You can lock the Tomcat account (do have to give it a shell, though) and no one should be able to get into the account. I use 'sudo' to allow others the ability to start and stop Tomcat which 'su's to the Tomcat user before executing. I myself use the Tomcat group, of which Tomcat is the only member, and apply root ownership to everything. You also need to make sure your WEB-INF is not in your docbase.

If not, check the access_log of Apache and see if you received an error there. If the access_log shows a "good" return code on the /manager, then check the mod_jk log (wherever you set it up to be logged) and see if there any errors there. You might be dealing with an issue where Apache does not recognize that /managers needs to be redirected to Tomcat. Or, passing that point, it may be that mod_jk is not able to pass the connection to Tomcat. Anyway, more info would be needed. One more thing to add: if you can embed the mod_jk configs you added to httpd.conf and any workers.properties/mod_jk.properties you setup, I can help you better.

It still looks like you have an issue with telling Apache where to go for /examples and any other webapps (like /manager or /admin). You need to add the JkMount directives in httpd.conf; they are sort of like redirects in that they tell Apache to send requests for, say, /examples/* to the available worker(s). My entry in httpd.conf for /examples: JkMount /examples/* loadbalancer "loadbalancer" is defined in my workers.properties file. For example, I have the follwoing in my workers.properties: worker.list=tomcat1,tomcat2,loadbalancer # # First tomcat server # worker.tomcat1.port=11009 worker.tomcat1.host=127.0.0.1 worker.tomcat1.type=ajp13 worker.loadbalancer.type=lb worker.loadbalancer.balanced_workers=tomcat1,tomcat2 Ben Ricker > Server.xml is as follows (standard apart from the references to mod_jk) > > > modJk="/opt/apache/modules/mod_jk-2.0.43.so" /> >debug="0"/> >className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" > debug="0"/> > > >type="org.apache.catalina.UserDatabase" >description="User database that can be updated and saved"> > > > > factory > org.apache.catalina.users.MemoryUserDatabaseFactory > > > pathname > conf/tomcat-users.xml > > > > > port="8080" minProcessors="5" maxProcessors="75" >enableLookups="true" redirectPort="8443" >acceptCount="100" debug="0" connectionTimeout="2" >useURIValidationHack="false" disableUploadTimeout="true" /> > > unpackWARs="true" autoDeploy="true"> >append="true" forwardAll="false" > modJk="/opt/apache/modules/mod_jk-2.0.43.so" /> > directory="logs" prefix="localhost_log." suffix=".txt" > timestamp="true"/> > reloadable="true" crossContext="true"> > prefix="localhost_examples_log." suffix=".txt" > timestamp="true"/> > home="com.wombat.empl.EmployeeRecordHome" >remote="com.wombat.empl.EmployeeRecord"/> > value="15"/> > override="false"/> >type="javax.sql.DataSource"/> > > usernamesa > password > driverClassName > org.hsql.jdbcDriver > url > jdbc:HypersonicSQL:database > >type="javax.mail.Session"/> > > > mail.smtp.host > localhost > > >global="simpleValue" > type="java.lang.Integer"/> > > > > > > > > Many thanks, > > David > > > > > > -Original Message- > From: Ben Ricker [mailto:[EMAIL PROTECTED] > Sent: 04 March 2003 16:37 > To: '[EMAIL PROTECTED]' > Subject: Re: Problems configuring Tomcat with Apache using mod_jk2 > > > You need to JkMount the /examples in httpd.conf.

Re: Problems configuring Tomcat with Apache using mod_jk2
You need to JkMount the /examples in httpd.conf. Something like "JkMount */examples blah" where "blah" is the name of your loadbalancer setup in workers.properties. It would help if you post the entries you added in httpd.conf for Tomcat. Also include your server.xml file for more information.

Are you sure you are not caching the web pages? Do you have caching on in the httpd.conf? Do you send the "pragma-nocache" in your HTML? Try changing the browser settings to always go back to the server and if you still get the old page, then look to see if Apache has caching on. I noticed that you are using mod_webapp. you might want to try to switch to mod_jk instead. It works with one Tomcat only; I have heard that it is a good idea to remobe the load-balancing weight when only using one tomcat.

Cookie Handling Question
We have some strange behavior going on, probably due to the strange setup one of our customers use. Before I get into it, some facts: Running Apache 1.3.27 with mod_jk 1.2.1 on two Redhat Linux servers talking to 4 Tomcat 4.0.5 instances. The Tomcats are running 2 per server on Sun Solaris 8 boxes using Sun's JDK 1.4.1. The Apache's are load-balancing to the Tomcats and we have a Cisco load-balancer in front of the Apache servers. Here is where it gets messy: the client is using IE 5.5 running on a Citrix terminal server. They are using multiple stations within a location and using the same account! So, user goes to station 1, logs in, does their business, then leaves the station without explicitely logging out of the app. They go to station 2, login, do their thing there then leavesetc. On top of this, there are other users who use the same stations but use different browser windows and different logins. The problem is that the user complains of having to re-login to station 1 after "a couple of hours" when he comes back to use the session he left open previously. Of course, with roughly 200 users at this site, we have only had 2 complaints of this behavior but we are doing "due diligence" to figure out what is going on. It looks like the browser is getting "confused" about which session cookie is the right one for the session and it sends the wrong cookie, thereby getting the "invalidated session, please login again" screen. Can anyone shed any light on how this sort of behavior might cause session timeouts because of mishandled cookies? How does IE 5.x know that a cookie is for this particular window, let's say, and not another? Are cookies tied to windows? Being a Unix sysadmin, I can only look out Windows (TM); I don't use them.

Error Log watcher
I am wondering if anyone has found a good error log watcher for Tomcat? Swatch does not work because it is made for syslog-type logs where an error message occurs on one line. So, it views a java error as one line, which really does not help. Anyone try any other programs?

RE: failing installation server.xml file
A few hints on using RPMs: get to know the --query (or '-q') option to RPM. Specifically, you can list out all files installed by an rpm by typing: 'rpm -ql Package_name'. To get the exact package name (RPM usually requires the full version number), type 'rpm -qa |grep package_name'. For example, type 'rpm -qa |grep tomcat' to get the full package name. Then type 'rpm -ql tomcat_package_name' to get all the files installed. This will give you tthe layout of all the files installed. I would also suggest going over the stuff in /usr/bin. They are probably shell scripts. You can see what configuration files are pulled in from there. Having said all that, I do not use the RPMs for Tomcat myself. I use Solaris as my Tomcat platform. The binaries, as suggested earlier, are the easiest way to go.

Although I am not John, I will fill his rather huge shoes for a moment... You need to set the JAVA_HOME variable. You can do this by setting it manually on the command line (type: 'JAVA_HOME=/path/to/java/install') or. better yet, assign the variable in the startup.sh file. Include a line at the beginning under the comments: JAVA_HOME=/path/to/java/install The '/path/to/java/install' depends on how you installed Java. If by RPM, I believe it is /usr/java/jdk_version#.

Both the server.xml and web.xml have changed. Here is a rough outline of how I moved from 4.0.5 to 4.1.18: 1) Installed new version in a different directory then older version. 2) Changed Listening ports to different ports so that old and new version could coexist without stomping on each other ports. 3) Started new version. 4) Checked to make sure all the examples and admin ran correctly in the new port (see docs) 5) Added old configs to new configs (i.e., added special loggers, setup mod_jk Listener, etc. I still keep the different port assignments) 6. Tested my Web Apps using the different ports 7. Take down new version and change port assignments to the same ports as old setup. 8. Take down old version 9. Start new version 10. Test, Test, Test.

Running just the examples, as was stated earlier, would rule out taking upwards of a gig of memory. I run a fairly sophisticated web app which gets roughly 100k hits a day our JVMs rarely take up 50-80meg a piece (they are 4 JVMs taking roughly 1/4th of the requests). I would suggest looking at vmstat and doing 'cat /proc/meminfo'. If you see 1gig+ memory allocation, you can do the math. If you have less then 1gig memory, you should definately see heavy swap usage. -- Ben Ricker <[EMAIL PROTECTED]> Wellinx.com -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>

An application like Tomcat, or the JVM for that matter, will always be multi-threaded. Green or Native has to do with how exactly the threads are created (I forgot the exact differences). What is the big deal with seeing multiple Java processes? Are you worried about RAM? Note that the threads all have the same memory allocation. You do not add those up; the shared memory is just that: shared amongst all of the threads. I would just forget about it and move on. You will not get a single PID. Well, I tale that back. Never say never when it comes to Unix; you might be able to list the Parent PIDS only by messing with the 'ps' options. I have never done that myself, so I suggest, if you feel the need, to look through the man pages for 'ps'.

Are you using Linux? Linux shows in-process threads as processes. If you are running Linux, then you are seeing threads within the Java process.

RE: is this normal??
I found a trick that might help: up your sar reports to take a snapshot every minute. Then, when you notice the CPU pegging, go through the sar reports for CPU usage and try to find the minute that they start. Then, you can go back through the Apache access logs (mod_jk.log perhaps), etc. to see if you can correlate a specific request with the the problem.

RE: is this normal??
There is probably a problem going on there. I find it strange that you have so much cumulative CPU time on the httpd processes. To me, they look hung (in so far as I can tell). Since most apps are transactional in nature (i.e., individual requests being fulfilled rather quickly), you would expect to see the Apache processes using CPU, then giving it up rather quickly. Of course, other httpd processes will also pop in and out of CPU usage as individual requests pop in. How long has this Apache/Tomcat been running? You might try a restart of both and see if the same behavior comes right back or if it takes time. You may have an issue in the app which is triggering a hang. Of course, on a "pretty busy web server", you may get such cumulative times, but you should still see httpd processes popping in and out of CPU usage as they handle their respective requests. If the same PIDs sit there pegging the CPU incessently, you most likely have an issue.

RE: running tomcat as a non-root user?
Additionally, you can add the "su tomcat -c" in a wrapper script that calls the startup.sh file. Mine looks like this: case "$1" in start) echo -n "Starting Tomcat..." /bin/su tomcat -c "/usr/local/tomcat1/bin/startup.sh" /bin/su tomcat -c "/usr/local/tomcat2/bin/startup.sh" ;; That way, you CAN use root (and a startup script) to start Tomcat and still get the security benefits of running as an unpriveledged, locked user.

RE: Urgent - Issue with Tomcat/mod_jk?
I beleive we are dealing with a different problem. My app has been running on Tomcat 4.0.6 for weeks until I had the problem recently. There was no crash. What happened was, it seems, a user REALLY fat-fingered the enter key or some smart person sent the same request to the server 180 times within one minute. I traced back through my access logs for Apache and caught the massive number if requests for one URL at the same time I had the problem. All of these requests overwhelmed the number of AJP13 processors I had configured (well, they are still at the default setting) and also caused a massive opening of database connections. Anyway, as to your problem: You may not have enough memory setup for your JVM. Do you send amx -Xm and -Xs parameters to Tomcat using JAVA_OPTS? You may be getting more load then Tomcat can handle due to a RAM constraint.

Re: Urgent - Issue with Tomcat/mod_jk?
I had suspected that in the problem earlier in the day (the part of the email I posted at the end if the last email you replied to). However, what did not make sense was the connection pool woth the database also going up. If I understand the stuff below, after 85 concurrent connections (max connections + accept count) I would start getting the "Out of Processors" error. However, I cannot see how this would cause the DATABASE connection pool to grow as large as it did (we usually handle 50k connections a business day with 5 pooled connections; during the earlier problem, the database connections went to *30*, our maximum). Additionally, why would we contine to get the following error: 2002-12-23 09:07:28 Ajp13Processor[12009][18] process: invoke java.io.IOException: Broken pipe at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:91) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:501) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:196) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:479) without seeing the "Out of Processor" msgs?

Urgent - Issue with Tomcat/mod_jk?
I posted a message earlier which has not received any replies so I will try another tact. The earlier mail is posted below this one. I have a production issue that has arisen in a setup of two Apache 1.3.27/Redhat 7.3 servers load-balanced across 4 Tomcat 4.0.6/Sun Solaris servers. Tomcat is running with Sun's 1.3 JVM. We have gotten a lot of the following errors in the "engine" log for Tomcat: 2002-12-23 15:21:56 Ajp13Processor[12009][16] process: invoke java.io.IOException: Broken pipe at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:91) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:501) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:196) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:479) We have also gotten calls from customers saying they are getting hanging screens in our application. We see no anomolies on out database, although earlier we did. Can anyone tell me what the error above is saying? Is it not able to write to the mod_jk? It looks like it is failing in some sort of closing routine (org.apache.ajp.tomcat4.Ajp13Response.finishResponse). Could this be a protocol issue? I am getting heat from my bosses on this one and I need to say SOMETHING! Please help if you can give me any clues or suggest possibilities. Thanks, Ben Ricker -Earlier Post- We saw a strange production issue this morning that seems to be related to Apache/mod_jk but I wanted to see if anyone can shed some lght on it. First, the environment: 2 Redhat 7.3 Linux server talking to 2 Sun Solaris 8 Tomcat 4.0.6 servers. Each server has 2 separate Tomcat instances for a total of 4. The Java uses Oracles JDBC drivers (not through Tomcat, but through a custom connection pool) to talk to an Oracle DB runnin on AIX 4.x. The first symptom was a huge spike in DB usage due to the creation of around 35 pooled connections to the database, This led us to think something happened on the database side, but it seems that the pool only grew on one of the Tomcat instances; the other instances showed the default pool size. The Oracle database did not show any locked tables or huge, hanging queries. The only problems I see in logs are related to mod_jk and Tomcat. First in the Tomcat engine log,I see: 2002-12-23 09:07:14 Ajp13Connector[12009] No processor available, rejecting this connection There are hundreds of these messages.

JAVA_HOME problem with 4.1.18
I have this weird problem with setting the JAVA_HOME env variable in Tomcat 4.1.18 (I also had it in 4.1.17). Here is the lines from my startup.sh: CATALINA_HOME="/usr/local/tomcat1-new" JAVA_HOME="/usr/local/j2re1.4.1_01" JAVA_OPTS="-ms32m -mx200m" export CATALINA_HOME JAVA_HOME JAVA_OPTS This setup worked in 4.1.12 and 4.0.6. Now, when I start Tomcat using the startup.sh, I get this: [root@dev bin]# ./startup.sh The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program What gives?

Latest stable version?
I am running Tomcat 4.0.6 in a production environment right now. I want to move to 4.1.x. I hear about 4.1.17. Is this considered production stable? It is probably MORE stable then 4.1.16, from what I have heard. However, the Jakarta site shows 4.1.12 as the stable branch of 4.1.x, but that has been that way for a long time. Is there going to be an increment soon to the stable branch?

Here is the line that workd for me in Apache 1.3.27 Are you using Apache 2.x? Redirect temp /index.html http://main.wellinx.com/servlets/Logon?STATE=0&USER=doctor The '/' by itself may not work.

Re: app roll out.
This would be done by Apache (though it could possibly be done by Tomcat; I use Apache). You can do it one of two ways: 1) Use mod_rewrite to rewrite "/index.html" to "/path-to-context-name". Not sure on the mechanics of this. Try the Apache list for pointers, or any number of tutotials on mod_rewrite. 2) Use the 'Redirect' directive in Apache. This is what I use and has worked for 2 years. Basically, you stick a line in your httpd.conf which goes: Redirect temp www.domain.com www.domain.com/path-to-context Hth, Ben Ricker On Mon, 2002-12-16 at 15:28, Alexander Wallace wrote: > Hi there.

Do you see that mod_jk is being loaded by Apache when you start it or in Apache's error_log? I see the following when I start Apache: Apache/1.3.26 (Unix) mod_jk/1.2.0 configured -- resuming normal operations I also will assume that you have the 'Include' statement in the httpd.conf for mod_jk.properties (as well as the LoadModule/AddModule directives for mod_jk.so). You might also want to bump the 'JkLogLevel' in your mod_jk.properties to get the debug level to get some feedback on what is going on.

For example, to run the examples through port 80 (and Apache), you would use the following: JkMount /examples/servlet/* ajp13 JkMount /examples/*.jsp ajp13 This will cause mod_jk to "intercept requests for /examples/servlets and /examples/*.jsp and send the request to the worker called ajp13 and setup in your workers.properties file. If you have another web app you want to use (I use /servlets for my setup, just use the JkMount for the path and the worker.

I pasted before I read the link below...that how-to is for 3.2. The one for 4.x is at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html.

RE: Apache-Tomcat mod_jk
You seem to be confused here. I believe you said you were accessing port
8080 when it was working. Now, unless you setup Apache to listen on port
8080, you were talking directly to Tomcat's web server. Now that you
have moved to Apache, you want to drop the 8080 and use port 80, which
Apache listens to by default (again, unless you changed it).
I would suggest that you post all the lines you added to httpd.conf,
your workers.properties conf file, and your server.xml file.
The JkMount directive tells Apache what path gets mapped to Tomcat; see
http://jakarta.apache.org/tomcat/tomcat-3.2-doc/mod_jk-howto.html for
more information about the directive.

Have you tried turning off the HotSpot JIT compiler and trying your test? All other things being equal, this will show you that the problem resides in the interaction between Tomcat and the compiled code. Just a thought...

Re: Two instances of Tomcat
Remember that with 2 Tomcats, you need DOUBLE the memory. You may be attempting to use more memory then you have in the box. Use 'top' to watch the memory utilization and see if you are filling up on memory to create the spreadsheet thingy. You can control the memory usage of Tomcat using the -Xmx and -Xms to control heap size. The settings you list would mean that you would need, at least, 1.1gig of memory in the box to utilize both Tomcats to their potential.

RE: I don´t understand the objective of thisopen list !
My advice: don't use it. We "geeks" who take the time to LEARN about the technologies we use will go about our business, using Tomcat. If you do not like it, please find another list to flame-bait on. Btw, I am running an App that has roughly 20k hits per day using a 99% dynamically generated web app (this is a rather small web app compared to others out there on the list) and I rely on it in a "life or death situation" (i.e., I get fired if I cannot keep up a 99% uptime requirement for 24/7/365). Tomcat works perfectly. Ben Ricker On Mon, 2002-12-09 at 16:04, Mike DiChiappari wrote: > You're correct.

RE: Thread dump
I am intrigued by this feature; it would help with the debugging of a application. I tried to test it against tomcat but I get nothing on stderr (i.e., nothing in /var/log/messages, terminal, directory I am in, catalina.out, or any of the logs for Tomcat). Could you expand on what behavior you see when you send the -3 to Tomcat's PID?

Timeouts can be a tricky business because of all the issues involved. In conf/web.xml there is a session properties where the default session timeout is 30 minutes. If that is not long enouhg, you can change it there. It does work; we tested it thoroughly (setting it to one minute, 30 minutes, and 60 minutes. It worked).
