Tomcat 4.1.18: 500+ Servlets locks up on Solaris under load
I have a Solaris server running Tomcat 4.1.18 and Java 1.3.0 with a single CPU and 2GIG RAM. The application has 500+ servlets that were originally developed under JDK 1.17b to run under the old Java Web Server on Windows NT4. The old system seems to handle the load much better than the new version. We have configured the Invoker to load the servlets automatically instead of explicitly naming them in the web.xml. I am launching the Tomcat server with the following parameters: -server -Xms384m -Xmx384m -XX:NewSize=128m -XX:MaxNewSize=128m -Xconcurrentio -Xincgc -verbose:gc under load the Tomcat server runs fine for a bit but once a servlet loads that retrieves a bunch of data, the CPU processing starts to increase until it pegs at 99% (according to TOP). All users then stop responding. The only way to recover is to terminate the process and restart Tomcat. The garbage collection indicates when the app becomes unresponsive the garbage collection shows a lot of full garbage collection cycles but the app never recovers - it essentially goes into an endless loop. Some of the parameters in our server.xml are: I am running Tomcat on port 80 as the root user if that has any bearing on things. Originally we had Apache in the mix, but to simplify figuring out the problems we have configured Tomcat to act as the web server for the time being. Some of the static resource directories are symbolic links.

Re: Tomcat 4.1.18: 500+ Servlets locks up on Solaris under load
I'm not sure if Tomcat is totally to blame, I'm sure when I figure out the problem it will point to our code. The reason I suspect Tomcat at this point is when the app is not under load (i.e. using Jmeter to simulate 10-20 user concurrent load) the app seems OK. the response times are acceptable even under as long as a servlet doesn't retrieve a lot of data. (I didn't write the app, just trying to fix it). The app is running fairly well under JDK 1.17 on Java WebServer on NT but falls on its knees under JDK 1.3.0 and Tomcat 4.1.18. We have done a bunch of other things on Tomcat (not 4.1.18) without having this kind of behavior.

Re: Tomcat 4.1.18: 500+ Servlets locks up on Solaris under load
We have profiled the app using JProbe and a couple of other tools. Nearly all of the servlets are very simple. They open a connection (from a pool), execute a query, cycle thru the result set, and then close everything (result sets, statements, connection, etc). The profiler does not show any hotspots in the code to speak of. Most of the servlets simply have a bunch of out.println(.); statements in them. We are moving to JDK 1.3.x because we have another app that can't run under 1.4.x yet. I'm not sure if there is much benefit going from 1.3.0 to 1.3.1x, but I am willing to try if that will help. Dov Rosenberg On Wednesday, March 5, 2003, at 04:28 PM, Shapira, Yoav wrote: Howdy, I would suggest profiling just your application, if possible, without a web server at all. Alternatively, run the web server with a profiler (OptimizeIt, JProbe, etc.) and try to allocate memory leaks. The profiler will show tomcat classes as well, so you can try to look for memory leaks there, but I doubt you'd find any. When profiling, be careful not to do it on your production server, as running with a profiler will slow things down a whole lot. As a side note: JDK 1.1.7 is really old. You app may greatly benefit from taking advantage of some of the newer features available in JDK 1.4.

Hello Kent and hello Dave,
The good news is that I too finally got JK2 working! It took an entire
weekend, but I got there in the end. I would next like to acquire a
complete understanding of how workers2.properties and jk2.properties
work.
At the time of implementing the JK2 connector I was directed to
several web
sites offering how-to's on the matter. However, I found many of them
related to the older JK connector, and apache.org site stated quite
clearly
that although JK and JK2 were similar in operation, their
configurations
were very different. Moreover, amongst those JK sites, there were
significant variations in configuration. In the end, I decided to
tackle it
alone. Well, that's not exactly true. Without Dave Short's
assistance I
would still be struggling, I'm sure. Thank you Dave!
I have drafted a procedure for setting up an Apache-Tomcat web server
environment, utilising the JK2 connector. I've checked its integrity
by
doing the same on a second computer - both running WinXP. I am about
to try
the same on a Linux box. If either of you (or anyone else for that
matter)
are interested in testing this procedure for correctness, please email
me
direct. Once it is proven sufficiently true and robust, if the demand
is
there, I'll post it on my home page.

2.0.44 and Tomcat

Comment out 8080 in the server.xml file because
Apache will serve up

Yes, paths now match up (workers2.properties appears

Windows attempts to shut Apache down - 'send report'

Apache apparently restarts. Any ideas? At least I
am making progress.
Well, I hope ;-).

I have used WAR FTP for the past few years. It is a very good server. It allows you to assign a person to a specific directory based on their login as opposed to MSFT that requires a different IP address for each specific user. The other benefit is you don't need to pollute your windows domain with unknown users, just put them in the WAR server. Much more secure. Dov Rosenberg P.s.

Re: virtual directory in tomcat
Instead of using relative paths in your application, use absolute paths , i.e. http://media.company.com/images/ What force Tomcat to serve your application and images, let Apache do the image serving, makes your application loads more scalable.

Re: Why should I use Tomcat vs .NET?
Contrary to what you think, a MSDN subscription doesn't mean that everything is free for the company. MSDN is licensed on a per developer basis. To be in compliance with the MSDN subscription, each developer that will be using is supposed to be licensed. All of the servers included in MSDN are developer licensed servers. When you deploy a production application onto a different machine you are required to purchase the proper licensing for the products involved including SQL Server, Windows 2000/XP servers, exchange server, etc. If the product is going to be deployed on an internet server, you must purchase the appropriate unlimited use license. A properly licensed production application can easily add $20,000 to the overall project cost just using the "things" that come for free in a MSDN subscription. Once MSFT starts enforcing their licensing a little tighter you will suddenly see the cost/benefits of open source solutions.

Re: context sharing problems
I think you should evaluate how your app is designed. If you need to communicate cross context/processes you should consider using something like JMS to give you good isolation. Today you may want to have everything on a single box, tomorrow you might want other servers. Another option to consider is to change the need for a singleton type of class or store some info in a database.

Re: Search engine friendly URLs
If you want to be able to scale your application, you need to be able to move the static image handling out of tomcat to a separate web server. Using Tomcat to handle both application chores and web serving chores will limit the overall scalability of your system. Short of passing parameters as session variables I don't think tomcat can do what you are asking. The big problem with using session level variables is that your pages can not be bookmarked. Most search engines can index dynamic pages pretty well. Just make sure the URLs don't include any session specific information, otherwise the search engine data is garbage On 10/2/04 7:59 PM, "Ben" <[EMAIL PROTECTED]> wrote: > I would like to use Tomcat alone > > > On Sat, 02 Oct 2004 19:37:35 -0400, Dov Rosenberg > <[EMAIL PROTECTED]> wrote: >> Use URL Rewriting with Apache.

Re: AW: Search engine friendly URLs
When I suggested using Apache I implied that Apache would be on a separate physical server. If possible even dynamic content can have static images that can be served up using Apache. Our application tracks references to the dynamic images that are stored in an application managed directory structure on the filesystem. The only thing Tomcat needs to do is generate the HTML pages, the web server handles all of the media requests. Otherwise your Tomcat instance is handling all of the requests thru a single network interface (unless you have multiple NICs and Ips) which will cause a significant issue under load and makes your application much harder to scale in a data center. Tomcat may be "nearly" as fast as Apache at serving images, but why burden it doing twice the work. I think the whole mod_jk thing is very poorly implemented. I haven't tried mod_jk2 - hopefully it is more efficient and easier to implement.

Re: Windows Environment Variables
The web.xml file is located in the /WEB-INF. Inside the element you can add multiple elements. Each context parameter has a name/value element nested inside. Like : ... DomainName demo ... You can access the context parameters using ServletConfig.getServletContext().getInitParameter() inside your servlet. -- Dov Rosenberg Conviveon Corporation http://www.conviveon.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Taglib loading classes of web application
Instead of checking the type of class by doing getClass().getName() I would
recommend using
If (myclass instanceof com.name.webapp.entities.MetaDataEntity){
...
} else {
...
}
This is better because you can check the presence of a class at compile time
instead of runtime when you do things like Class.forName(className)

Re: Does Oracle 9i thin jdbc driver work in Tomcat 5?
I have successfully used Oracle 9 with JBoss, Jrun, and Tomcat. I don't remember any specific differences between the JNDI configurations. Make sure that you have the classes12.jar, nls_charset12.jar files in your runtime classpath, i.e. /WEB-INF/lib or somewhere else. The driver class is oracle.jdbc.OracleDriver The URL format is: jdbc:oracle:thin:@:: In your code you need to create an instance of the Oracle connection pool class. I think Oracle10g renamed the jar files to something like ojdbc14.jar.

Re: hide source of a page
Apple's iTunes application and store is a good example of a private label browser. The store is a web application (WebObjects based - very cool technology). Instead of delivering the content via http://... They changed the protocol to itms:// and registered their iTunes client to be the helper application for that protocol. They conveniently hid the view source from their web store. Itunes is a pretty cool example of doing what you want. On 11/8/04 9:52 PM, "Steven J.
