High Load examples?
Hello. Right now, we're using Bea WebLogic as our application server. We'd like to change to Tomcat 6. Now the creator of the application being run on the App Server said, that Tomcat works very well under low usage / low load situations. But if there are many (unsure about the definition of many...) users, Tomcat might tend to not perform so well anymore. I suppose many might mean like 50-100+ concurrent users using the App or system at the same time. Now I'm wondering, if that's actually true - does Tomcat not perform well anymore, if there are many users using it? Does anyone of you maybe have real world examples of high profile / high load sites using Tomcat (6)?

University of Leeds routinely had 100+ active users on its Bodington VLE, and I'm aware of Sakai sites that load-balance across 4-8 Tomcat application servers that can serve around 5,000 concurrent users. A correctly configured Tomcat has no problem at high loads. It's barely possible your application creator might be talking in code for the following: Something in WebLogic means that our application runs fine, whereas something in Tomcat tickles a bug in our application that means it doesn't scale.

Does anyone of you maybe have real world examples of high profile / high load sites using Tomcat (6)? The powered by list [1] is a good place to start. The reference I usually use (because I work for SpringSource) is actually a tc Server reference [2] but all the stuff that matters (the nice things they say about increased throughput, lower server load and improved scalability) is pure Tomcat. In my experience if an app performs badly under load it doesn't matter what application server you run it on it will always perform badly under load. With well written applications I have seen a single Tomcat instance handle 1600 concurrent requests all with sub-second response time quite happily with 1GB RAM and ~5% CPU. In that case the load testing framework fell over long before Tomcat even looked like it might be struggling - but it was a *very* well written application. Equally, I have seen applications with issues struggle to manage 10 concurrent users. Keep in mind that you may need to tune threads, memory and GC settings to suit your app and the associated load.

java shutdown hook and classpath
Hi and Happy New Year! I have a library that uses JDBC and is being used within a my web app. The library and JDBC driver jars are in the web app's WEB-INF/lib directory. The library installs a Java shutdown hook, which ultimately uses the JDBC driver to do some clean ups in the database. I'm getting a class not found error when trying to load the JDBC driver (in this case derby) in the hook. I suspect this is because the shutdown hook has been called with a class loader that does not have access to WEB-INF/lib. Any thoughts or solutions? Thanks.

They are actually instance variable. I'll check if moving them solves the

Notice that there are no number on the first line and it is usually
the case.
The code that is responsible is:
private ServletOutputStream out;
private InputStream in;
...
in = new FileInputStream(tmp);
...
out = response.getOutputStream();
byte[] buf = new byte[8 * 1024]; // 8K buffer
int bytesRead;
while((bytesRead = in.read(buf)) 0) {
out.write(buf, 0, bytesRead);
}
The updated code didn't change anything in that Servlet so I really
have no clue what happened. It happens on tomcat 6.0.18 and 6.0.20.
Java is 1.6.0_11.
Thanks for any help.

Re: High Load examples?
of course there can't be a high-load thread without me, so here are my 2 cents: 2 cents I'm working in high-performance high-portal environment since 2004, and i must say that starting with tomcat 5 i've never experienced any performance problems caused by tomcat itself. The number of concurrent users and, more important, concurrent requests on a tomcat instance are limited by your network bandwidth, your cpu, your ram and, first of all, your application but not tomcat. My largest installation served more than 30.000 concurrent users, which produced about 4.000 requests per second (cumulated over few machines) all well under 500 ms delivery time. However the application was optimized for performance and scaleability. So, with 95% certainty your problem won't be tomcat! :-) Go for the kitty ;-) /2cents regards Leon - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Running two tomcat servers on same system?
Hi, I am wondering if it would be possible to have two tomcat servers running on the same system this is because some features of my software have to be on the internal network and there is a set directory that is accessible to the outside world. And my idea is to split the application in to two. This is so that the public stuff can run along side the private stuff and not interfere with each other. At present I have the IP address allowed to access the application unblocked from accessing the port of my internal network, which has to be changed every time the IP address changes of the one server allowed to access it. However I could open another set of ports run another tomcat server and host my private stuff there. Also is it possible to share shutdown ports of tomcat servers? Thanks in Advance Dean Chester

Re: High Load examples?
+1 As usual it depends highly how well your app is written and where your bottleneck is. On a project, our very poorly-written Tomcat app was failing at ~50 concurrent users. BUT it was always because of the Oracle DB being starved on its 4 cores - 8GB of RAM machine. :-( On another project, we've written an app without any real concern for scalability at coding-time and it was easily able to accept ~2000 concurrent users on each of our 8 cores - 32GB of RAM machines on an ISP connection. It was more than asked, so we didn't try to benchmark the app more than that. But it was without any doubt and from the very beginning a better skilled team. So your mileage may vary and I'd advise to try and benchmark it using a load-testing tool.

Incompatabilities?
Good Morning! Thanks a lot for all the answers you provided yesterday in my other thread, asking about scalability of Tomcat. Appreciate it! Besides the load issue, they claim, that a different app of theirs doesn't work with Tomcat, but it's supposed to work with WebLogic and jBoss. Am I right in assuming, that this is most probably caused by bugs in their app, which (somehow only) get triggered by Tomcat? Can't be any more specific here, sorry. I don't know what kind of errors these (supposedly...) are and I'd rather also not name the App and Manufacturer (only so much: it's by far not a small company making the app and the app is used quite a lot in its field and, of course, it ain't cheap...). I'm simply asking to figure out the validity of their claims.

Sorry to pick you up on this one, Mike, but I think you're thinking of Local*Service*, not Local*System*. LocalSystem has full administrative access to the local computer, including (for example) being able to write a rogue DLL to a spare directory, then amend the registry so that that DLL is loaded by every process that runs on the machine from this point onwards. Or create a new local account that *does* have desktop access and spawn a process running as that user. If you can compromise LocalSystem, you've got the machine. Windows' LocalSystem is very, very close to Unix's root. If you want a non-privileged account, use LocalService not LocalSystem.
