Re: Tomcat problem on a multiple CPU system
just 2 cents, if your 8 IEs are running in one process, which is default to my knowledge, they are sharing the same urlhelper/toolkit which default to 4 max parallel connections. I suggest you write a small java programm that tests it for you (with commons-httpclient) or use jmeter or at least wget/curl. regards Leon On Mon, May 5, 2008 at 1:10 PM, Gilbert, Antoine [EMAIL PROTECTED] wrote: I open 8 IE on a remote computer, basically once a JSP is called, the browser is just waiting the process to be done. -Original Message- From: David Smith [mailto:[EMAIL PROTECTED] Sent: 4 mai 2008 23:00 To: Tomcat Users List Subject: Re: Tomcat problem on a multiple CPU system Can you describe how you open the 8 browser windows and what browser you are using?

How do you make the connection to the servlet. Does the browser run on the same machine as the application? 2. Does you application create network traffic? If so, how many bytes are transferred to the browser? Each servlet thread will have to wait until the application has transferred all the data out. 3. What kind of disk activity does your application generate? Is it different when the app is running from the servlet? Probably somewhere your servlet threads are sleeping waiting for a resource. You could do a thread dump to see what is happening (I don't use Windows so I can't remember how you do that with the Win setup) In the end, you'll need to profile the system to work out where the bottlenecks are. You'll need to use network analysers and probably Java profilers to track down what's happening such as when packets are received, when the replies are generated and maybe profile what your app. is doing.

Re: CPU usage quirk with multiple tomcat instances
Yes, same webapp load - i.e. they're both handling the same number of transactions per second. I guess the only advantage of multiple JVM's is reliability - if one instance goes down the other can still handle load on that machine. Also; I guess someone thought originally that 2 instances doing less work would be easier for the VM to handle and therefore more performant than one instance doing it all - clearly not! ( I didnt set this architecture up - If it's best practice to use one VM on each app server then fair enough - i'd like to read up why tho! ) Thanks!

Re: CPU usage quirk with multiple tomcat instances
Hello Dan, what also may happening is that you have unneeded or errorneous synchronisation somewhere in your code. Two instances : less code in same block and vm, effectively less synchronization. try to profile whether some use cases take longer on the single tomcat per machine. We once tried to run multiple tomcats on one machine and the results where opposed to yours: less performance, so i think your app behaves funny :-) regards Leon On Fri, May 2, 2008 at 2:42 PM, Lists [EMAIL PROTECTED] wrote: Hi, We have a Tomcat app that is loadbalanced by hardware. I have 4 boxes available in our test env, all of which vary slightly but not massively in spec. Anyway I moved from 2 tomcat instances on each machine ( listening on different ports ) down to 1 and I noticed for the same load the cpu utilisation dropped by 20%. Interesting, how can this be explained? Is this the extra effort in tomcat or something? Or is it memory related? the 2 instances had 1gb each, and the single one has been given 4gb. However I have jprofiled the instance and it has never seemed memory hungry. Anyway I suspect even at 2gb for 1 instance it would still be 20% less cpu - i can always do a run to prove this if people think that necessary.. Another thing i've found is that on one server I have abnormally high CPU utilisation for the same load. I've checked the logging levels are all the same as are the java VM and the VM config settings. I wonder what else could cause this? All i can think is some sort of OS or hardware malfunction! maybe the CPU cache is duff or something. Many thanks to any input to my Friday weird-ness!

Tomcat Production Configuration
Hi All My question concerns optimizing Tomcat. Our setup is roughly this: - Dual Quad Core with 8 gigs memory (4 gigs dedicated for Tomcat) - Single instance of Tomcat6 - Single web application (Java Servlet) - AJP connector A little about the application: The site is relatively low volume, however traffic spikes when our newsletter is sent out. The application is complex and connects to a large research database serving a number large pages with reports, charts, data tables etc, which are generated dynamically from live data... sessions tend to get quite large. My thinking is that I should be supporting in the region of 200 to 300 sessions as a minimum. So given this setup, how should I configure the connector with regards to: maxThreads and any other relevant attributes. I am thinking of about 300 threads? I would be grateful for your advice.

How to use a custom formater for org.apache.juli.FileHandler
I have
changed logging.properties file in conf directory so that i have
different log files for different web apps.
This is what i have changed/added to that file:
handlers = 1catalina.org.apache.juli.FileHandler,
2localhost.org.apache.juli.FileHandler,
3manager.org.apache.juli.FileHandler, 4admin.org.apache.juli.FileHandler,
5host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler,
6nomad.org.apache.juli.FileHandler
...
6nomad.org.apache.juli.FileHandler.level = FINE
6nomad.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
6nomad.org.apache.juli.FileHandler.formatter =
biz.zviz.util.logging.NomadLogFormatter
6nomad.org.apache.juli.FileHandler.prefix = nomad.
...
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/Nomad].level
= INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/Nomad].handlers
= 6nomad.org.apache.juli.FileHandler
Everything works O.K. if I do not set my custom formatter or if I set
java.util.logging.SimpleFormatter. But with custom formatter I loose all
LogRecords from /Nomad.
My formatter implementation is:
public class NomadLogFormatter extends java.util.logging.Formatter {
public NomadLogFormatter() {
super();
}
@Override
public String format(LogRecord logRec) {
long time = logRec.getMillis();
String msg = logRec.getMessage() == null ? no message :
logRec.getMessage();
return String.format(FORMAT_STRING, time, msg);
}
public static final String FORMAT_STRING = %1$tF %1$tT - %2$s%n;
}
I tried to put this class to common/classes, i have tried to put
NomadLogFormatter.jar to common/lib, also to include it to my web app, but I
always get this exception as first message when do restart Tomcat:

RE: JAAS authenticated user fails authorization check
Problem is, the GenericPrincipal class is in the Catalina jar, which is available to Tomcat as a native library but for me to make use of it, I'd have to include it in my web-app lib. I was hoping to be container-agnostic and avoid any proprietary libraries, which is why I used JNDI and JAAS. I want to be able to hook into my security wrapper without necessarily going through Tomcat's security realm. So, my options are to include the Catalina jar in my context or create my own mappings between resources and roles. In the former case, I'll have a maintenance issue, because I'll have to ensure that the developers know that the jar needs to be kept in sync with the Tomcat environment. In the latter case, I'll be manually doing what Tomcat can do. However, if I am to be truly agnostic, that is what I should do anyway. Thanks for your help, Chris, it's been very valuable.

RE: Installing tomcat on multiple cpu X_86 64 bit machine
From: sur_1805 [mailto:[EMAIL PROTECTED] i m using linux(RHEL 5) with 16 GB RAM. OK. Is it possible to split the JVM off into multiple processes for the hundreds of threads we end up running? Sort-of, but think: why would you want to? Modern Linuxes can handle hundreds of threads per process without worrying. If you want to do this, you could run multiple JVMs with some kind of load-balancer in front of them. Some sites do this for reliability - losing one JVM doesn't kill the site. There's another thread on the list at the moment that shows that some people find it slower, others find it faster. It seems to depend on the application. There is no way of splitting a *single* JVM into multiple processes. How much memory i have to allocate to heap memory that is sufficient and do not become the major performance bottleneck.? As much as your application needs - and that depends almost entirely on your app, as I suspect under 1% of the load will be Tomcat's overhead! Your only way to find that out is to profile your application, on your hardware, with your database, under your realistic load.

RE: JAAS authenticated user fails authorization check
Chris, You are quite correct about the classpath contention. I should have been clear; to make use of the libraries in my IDE, I'd have to include the jar in my lib folder for development, not deploy the jar with the web-app. That, or use introspection to avoid the IDE compile problems and then rely on Tomcat to create the necessary objects at runtime. I'm not a fan of programming around exceptions, though, which I'd need to allow the security wrapper to be deployed to another container. As for JAAS and creating your own Principals, I think that's pretty much a requirement, if you're doing something other than using the java.security file and using a GUI app. There aren't too many Principal types, for any customizations you may need to make. For example, Tomcat has its own GenericPrincipal class, as well as security principal, whos type I forget at the moment. The JAAS login method uses a callback handler, which normally puts up a dialog when login() is called without credentials in the handler. Obviously, that's not really an option with a web-app, so you have to roll your own login() and commit() implementations, using the callback handler as the data source to populate your Principals. So, if you want to use JNDI and JAAS, you have no choice but to write your own JAAS module that hooks into your own JNDI module, since Tomcat handles one but not both. Basically, I really don't like having to specify LDAP account information in clear text in a tomcat config file. As well, with my own implementation, I'm not reliant on securing access to my resources via HTTP requests. It is definitely more work but is a lot more flexible in the end. -Robin. -Original Message- From: Christopher Schultz [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 06, 2008 3:06 PM To: Tomcat Users List Subject: Re: JAAS authenticated user fails authorization check -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Robin, Robin Coe wrote: | Problem is, the GenericPrincipal class is in the Catalina jar, which | is available to Tomcat as a native library but for me to make use of | it, I'd have to include it in my web-app lib.

Re: Tomcat Production Configuration
Hi, I'm not sure if this will apply in your case, but I found that offloading the mail to a second (relatively low spec as it happens) local machine improved the mail output rate considerably - mailouts went in about 1/4 of the previous time. The local mail server was using CPU cycles and the servlet app using lots of memory in our case - combined on one machine the overall load rocketed and the web app seemed to suffer most.
