The numbers suggest, that you've got 210.000 * 12(instances) / 21 (days) = 120.000 requests/day So depending on the time distribution, this should boild down to about 5 requests/second peak load.

Number 3_1 really looks suspicious. Maybe it has been in error status/down/stopped/disabled for a longer time? Remember: method B tries to keep Busy even. This could mean, that the workers get different numbers of requests over a longer time. Nevertheless I would not expect such huge differences as with 3_1. All other numbers are plausible for B with stickyness. The differences in Busy numbers (0 to 5) could be related to stickyness. If you are using URL encoding you can have a look into the apache access logs to determine the rate of requests going to tomcat, that carry session info. If you are using Cookies, you can log the incoming Cookie header in the log (check docs for mod_log_config for the syntax for incoming headers) and do the same check. If you've got relatively few requests without session, then think of it as first feeding most requests into their sticky slot and then adding only a few to the remaining slots with lowest (usually 0 or 1) busyness.

Re: Mod_jk load balacing algorithm
Hello: Thanks for those explainations. We will have to look further on the behavior of that server3_1 node. On the 'P' option which was recommended by Mladen Turk some time ago when we had issues (share memory locking) with a older version of mod_jk ( 1.2.15), we have left it as it is. But if you recommend that 'O' locking gives better performance on new mod_jk versions we will be looking into changing it after testing under our applications.

The data is sent via an HTTP POST request, with the query string lightly encrypted. if it's sent to the servlet using a POST, is there anything wrong with using the hreq.getParameterNames() hreq.getParameter(param_name) methods?

Peter Crowther wrote: From: David Kerber [mailto:[EMAIL PROTECTED] Is there a more efficient split method I could use? Or am I completely missing the point of what you are suggesting? I think you've slightly missed the point. I assume you're calling your function 5 times, each with a different field name that you want out of it. You're then invoking string handling functions on the entire decrypted string 5 times, each time going through the bytes to extract the piece you need. In the process, you traverse bytes you don't need several times. My suggestion is that you tokenise this *once*, and hence only pay the string-handling overhead once. Then you get all the parameters out of the same tokenised version. However, if the next thing you do is to write this to disk, I am even more convinced that you're optimising the wrong piece of code as the disk I/O is likely to take vastly more instructions than the string parse. These may be naïve questions, but I'll ask them anyway. How have you identified these two pieces of code as the targets for optimisation? What profiler have you used, under what conditions? What proportion of your overall CPU budget is taken by these two snippets of code? Is the machine CPU-bound in the first place, or is the bottleneck elsewhere?

RE: Code performance question #2
From: David Kerber [mailto:[EMAIL PROTECTED] Do you think it be more efficient to scan the string once and grab the field values as I get to each field marker? Yes. Yes, the machine is cpu-bound. My 768k data line will spike the cpu to 100% and hold it above 95% until the transmission queues on the other end of the WAN are caught up. (Wince). Ouch. watching task manager tells me that the disk subsystem seems to be able to keep up. If you're on Windows, start up Performance Monitor and add the following counters: Processor: % CPU time Memory: Pages/sec Physical disk: Avg disk queue length (by array or disk if you have more than one) (I would add network: Bytes/sec, but it seems that's not the bottleneck) The key disk counter is the queue length. MS documentation suggests that when the average queue length climbs above 2 per spindle in the array, your disk subsystem is likely to be the bottleneck. So if you have a 5-disk array, queues that climb over 10 show a disk issue. Memory: Pages/sec is a general indicator of paging traffic. COnsistently high values tend to show a paging problem that could possibly be solved by adding RAM. Processor: % CPU time is a general processor counter. Sustained values above 80% tend to indicate a bottleneck according to MS. It's sometimes worth adding the % user time counter as well to see whether the issue is your code or OS code. I haven't run a profiler on this code; I've tried, but getting the configuration figured out has stumped me every time. I picked out these particular routines (and one other I haven't posted) because of the principal that 90% of the cpu time is taken by 10% of the code, and these routines are the only loops in the entire servlet (i.e. the only lines of code which are executed more than once per incoming data line). Seems like a reasonable heuristic, I agree. You may find that Tomcat itself is the bottleneck - this is an area where profiling is of great help. However, I'd beware hidden complexity: the complexity behind function calls into third-party libraries. For example, you say you're decrypting the arguments. Depending on the exact crypto algorithm used, this ranges from moderately expensive to horribly expensive; once again, profiling would reveal this, and might indicate where a change to the crypto could be of benefit. Can you set up a simple Java test harness outside your servlet that simply calls the servlet's service routine repeatedly with a few sample lines? If you can construct something that will run outside Tomcat, it'll be easier to instrument and you'll be able to analyse the impact of your tuning changes more easily. I also see Mark's willing to help getting a profiler set up... :-). Sorry to point you off in a different direction from your likely preferred route, but I've seen a lot of people spend a lot of time optimising the wrong area of their code. In a past life, I wrote highly-optimised classifier code for an inference engine (admittedly in C++); I found a profiler was the only way to work out what was *actually* happening. I ended up getting a factor of 20 out of my code by combining optimisations in the most unlikely places, giving the company the fastest engine in the world at that time. I simply couldn't have done that with static analysis - I kept guessing wrong! - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Client Certificate -- All Authenticated Users
All: I am writing an Application which is using client-cert as an authentication process. I successfully configured Tomcat to use SSL and ask for the certificate and everything works. However I still have one problem. In order for the the security to work I have to add the DN of the certificate to the tomcat-users.xml file. So you have something like this: ?xml version='1.0' encoding='utf-8'? tomcat-users role rolename=tomcat/ role rolename=role1/ user username=CN=Alice SPECIMEN (Authentication), C=BE password=null roles=tomcat,role1/ user username=tomcat password=x roles=tomcat/ user username=role1 password=x roles=role1/ user username=both password= roles=tomcat,role1/ user username=SERIALNUMBER=xx, GIVENNAME=yy, SURNAME=zz, CN=www, C=dd password=null roles=tomcat,role1/ /tomcat-users The web.xml is configured in the following way to allow all authenticated user to do stuff. (To my knwoledge the * means all authenticated users, in my case users belonging to role1) ... login-config auth-methodCLIENT-CERT/auth-method /login-config security-role descriptionAuthenticated Users/description role-namerole1/role-name /security-role security-constraint display-nameconstrained1/display-name web-resource-collection web-resource-namejspPages/web-resource-name url-pattern*.jsp/url-pattern http-methodPUT/http-method http-methodGET/http-method http-methodHEAD/http-method http-methodTRACE/http-method http-methodPOST/http-method http-methodDELETE/http-method http-methodOPTIONS/http-method /web-resource-collection auth-constraint role-name*/role-name /auth-constraint user-data-constrainttransport-guaranteeINTEGRAL/transport-guarantee /user-data-constraint /security-constraint /web-app If I do it like this, it works perfectly and the the request.getUserPrincipal() has a value. However this means that I have to add the DN of all certificates in use to the tomcat-users file. I my case this is impossible. For me a user is authenticated if his client certificate is accepted (meaning it was not revoked -this where ocsp and clr's come in- ). So here is the question: Is there a way to configure tomcat in such a way that, when tomcat accepts the client certificate, the user is automatically authenticated (and belongs to a default group) and the request.getUserPrincipal() is filled in with the relevant information from the certificate.

Re: Taglibs ; error in a JSP using expression langluage
which version of tomcat are you using?

Try setting the following attribute in your JSP 'page' directive.

My web.xml has an entry:

Re: tomcat JSP Servlet Apache JK2
jk2 has been deprecated quite some time ago. You might find some help for it on this list, but you should seriously consider migrating to mod_jk. The module mod_jk (*not* mod_jk2) is still being actively developed and most features of mod_jk2 have been backported to mod_jk in the meantime. I'm not saying, that your problem is a mod_jk2 problem, but you can assume to get easier help when using mod_jk. Please note, that the last released version of mod_jk is 1.2.18.

Can I use mod_jk with Apache2? Uaaah. mod_jk 1.2 works with Apache 1.3, 2.0 and 2.2. The differences between mod_jk and mod_jk2 have nothing to do with apache 1.3 vs. apache 2.0. But: The build results of mod_jk differ for Apache 1.3 and 2.0. So when building it, you have to decide, for which web sserver you build it. It's not possible to use a mod_jk binary built for 1.3 with Apache 2.0. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Mod_jk balancing, session problem
Artur wrote: Hello, We have environment with Apache (2.2.0) + Tomcat (5.5.17) connected via mod_jk (1.2.18). Further tomcat makes some queries to databese through Tuxedo services (BEA). Everything works fine until heavy load when something stops responding (Service not available). We think it is tomcat or mod_jk. It occures when Max busy connections on mod_jk status manager shows about 200. Mod_jk is in error status then. Understanding this situation would be helpful to decide, if adding another tomcat really helps (problem=database = more tomcats don't help etc.). So we decided to use mod_jk load balancing feature and we installed another instance of tomcat (on the same machine). Now service is available even under heavy load but we are losing sessions. What do you mean by losing sessions? I expect you mean users work in a session and then they send a request and get a response indicating, that the requested session has not been found? If so: - does it happen in times, when you get errors in the mod_jk-log? Does it happen at all times, or do you have peaks at special times? Stickyness sends users to the correct node, except when the node is not reachable (error, stopped). In this case users will be sent to one of the remaining nodes and - of course - without session replication their session will not be there. Session repllication means to establish a tomcat clusster, something you need to carefully test and that might force changes in your app. - if it happens even when there's no other problem at the same time: make session IDs trackable. Either your app uses URL rewriting, then your session ID is part of every request and logged in the apache access log. Or you use Cookies, then add logging of incoming header Cookie to your mod_log_config LogFormat. If you also add outgoing header Set-Cookie you are able to follow the sessions, and you can decide, if the users really send the correct session ID. Sometimes what you may find is: the previous request produced an error in the app, which then decided to invalidate the session. You can also add a request log to mod_jk, that logs, which worker has beend chosen for every request. That way you do not rely on your user feedback, but can measure the problem yourself (how many users/sessions, what time of day etc.). Of course sticky_session is set to true.

Strange error referencing JRE when integrating with MyEclipse
Hey everyone... Quick question that will probably take 5 seconds to answer... I'm using the following configuration: - Tomcat 5.5 - MyEclilpse 5.0 (Eclipse 3.2) - J2sdk1.4.2_12 I set MyEclipse to point at the 1.4 version of the JDK (the only one on my system as far as I can tell). When I try to startup the server from Eclipse, I get the following error: This release of Apache Tomcat was packaged to run on J2SE 5.0 or later. It can be run on earlier JVMs by downloading and installing a compatibility package from the Apache Tomcat binary download page. I'm a bit confused as to why it's giving me this error - since Tomcat appears to be running fine on my machine (I can access localhost:8080/ just fine). Any ideas? Thanks, Chris

Modifying saved URL from j_security_check
Hi list, imagine a framed web-application: After session-timeout, the user clicks on a link in an outer frame which has the inner frame as it's target. What happens? j_security_check is called, login-page displayed, authorization performed and saved url is requested. Unfortunately, your framed view gets lost. Therefore I'm looking for a possibility to modify the savedURL in j_security_check. I know that a filter in tomcat can't be applied to j_security_check, I've tried a Valve, however, I can't access the neccesary objects like org.apache.catalina.session, when inheriting from ValveBase. Has anyone from the list ever manipulated j_security_check? Or does anybody have an alternative solution (like writing an own j_security_chjeck)? Inserting frame-breaks into the html-pages via Javascript is, unfortunately, not an option. Any suggestions higly appreciated!

Just to add a note on this thread. The Tomcat/OpenEJB integration now runs in three modes. The first two are as you mentioned: OpenEJB beside Tomcat in a separate VM; OpenEJB embedded into Tomcat and available to all webapps. The new third style is OpenEJB embedded into a *webapp* and available only to that webapp -- each webapp can have it's own private ejb container. The webapp can even have remote ejb clients that communicate with it's ejbs over HTTP. With this style, you don't even have to have a separate ejb archive -- you just add a META-INF/ejb-jar.xml file to your webapp and you're done. That's pretty much my preferred integration style now.

User database and user attributes
I am using the Tomcat user database to hold information for users. What I need to do is retrieve the group a user is in from the database. My problem comes when I have a servlet add a new user, assign it to a roll and a group, then try to access the user from another servlet running in the same context. I often get exceptions thrown when I call the save() method on the user object stating that Tomcat cannot rename the tomcat-users.xml to tomcat-users.xml.old. The user info is still in memory and if enough time passes or the server is stopped, the data eventually gets flushed to disk. There are methods for finding the user, finding a roll, and finding a group, but I dont see a method for finding a group for a given user using the MBeanServer(). I had been using the XML libraries to load the database and then search through it finding the user then getting the assigned roll but it only works when the new user information is flushed to disk. What would be the best way to do this? Robert S.

mod_jk log level and logging issues
Hi: These following issues are observed with mod_jk 1.2.18 on Linux and Solaris 8 with apache 1.3.27 and 2.2.2 (4 combinations). issue 1: With mod_jk 1.2.15 i set my jk log level: JkLogFile logs/mod_jk.log #JkLogLevel info JkRequestLogFormat %w %V %U %s %T %B %H %m While switching to 1.2.18 I read in the fine manual that the default log level is info so I removed the directive, and.oh my ! the default is now debug :-) Not a big deal, but I do wonder a little bit if this is a problem in my build only. Does anyone get the same result ? Ref. http://tomcat.apache.org/connectors-doc/config/apache.html issue 2: When Tomcat is down I get the following mod_jk.log error mesg and JkRequestLog entry: . . . [Tue Aug 08 14:34:33 2006] [23653:] [error] ajp_service::jk_ajp_common.c (1794): Error connecting to tomcat. Tomcat is probably not started or is listening on the wrong port. worker=myWorker failed [Tue Aug 08 14:34:33 2006] myWorker myserver.mydom.com /myapp/jsp/hello 200 0.000378 0 HTTP/1.1 GET . . . The JkRequestLog entry shows a http status 200 whereas the browser (apache httpd) reports properly 503. Also any url that would normally show a status of 404 show 200 when tomcat is down. This is a bit unexpected but it appears that 1.2.15 is doing the same. Hence a broken tomcat can actually make a log stat look very good :) Thanks, Fred -- View this message in context: http://www.nabble.com/mod_jk-log-level-and-logging-issues-tf2075041.html#a5714385 Sent from the Tomcat - User forum at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: User database and user attributes
Robert Harper wrote: I am using the Tomcat user database to hold information for users. What I need to do is retrieve the group a user is in from the database. My problem comes when I have a servlet add a new user, assign it to a roll and a group, then try to access the user from another servlet running in the same context. I often get exceptions thrown when I call the save() method on the user object stating that Tomcat cannot rename the tomcat-users.xml to tomcat-users.xml.old. The user info is still in memory and if enough time passes or the server is stopped, the data eventually gets flushed to disk. There are methods for finding the user, finding a roll, and finding a group, but I don’t see a method for finding a group for a given user using the MBeanServer(). I had been using the XML libraries to load the database and then search through it finding the user then getting the assigned roll but it only works when the new user information is flushed to disk. What would be the best way to do this?

Tomcat Book Recommendation?
Hello, Are there any text books / reference information about Tomcat on the maket that are considered to be the must haves ??? Years ago, I owned James Goodwills book and that was great, however that is old information now days. In particular, what I am looking for is a systematic approach to Apache / Tomcat development with the emphasis on Tomcat of course. Thanks, M Goodell - Talk is cheap. Use Yahoo!

Session cookie location?
I need to find out where the session cookie is located on a Windows client running Internet Explorer. I have searched in all of the usual directories and can not find it.

getRealPath and war file
Hi all, I know that this question has been asked many times, but still something not clear for me. When an application is deployed as a war file, (as mentioned in the javadoc, or in several messages), context.getRealPath() will return null. However, Tomcat creates automatically a directory under webapps to contain war file contents, so I am wondering if Tomcat is using the newly generated directory to load the application(1st case) or the war file (2nd case). In the first case context.getRealPath(/) should return the path to the newly generated directory. In the second case, why does Tomcat generate the directory to contain war file contents?

Re: getRealPath and war file
Hi, Most of j2ee application servers (tomcat, jboss) when a war or ear file is deployed. It will generate a folder which contains the same file structure (web application format) as which is in the war or ear file. A war is considered as a file but not a path. So if Tomcat only reads war but not a directory based content, it has problem (when changes to parent path, or changes to child path). Besides, a war is a packed jar file, reading a directory based content is a lot more easier and faster than a packed jar file.

If unpackWARs is true then the WAR is unpacked and the unpacked files are used to load the application. In the first case context.getRealPath(/) should return the path to the newly generated directory. To the best of my knowledge, it does. In the second case, why does Tomcat generate the directory to contain war file contents? The directory is only generated if unpackWARs is true. Tomcat should never, and doesn't as far as I am aware, unpack the WAR and the load the app from the WAR. You should also bear in mind that using antiJARLocking and/or antiResourceLocking will also cause additional copies of files to be made.
