Re: Multiple IIS sites and ISAPI redirect problem
Mikko, Please elaborate what you mean by doesn't work? Errors or IIS 404 or Tomcat Errors? Multiple sites - is it multiple Tomcat instances or 1 Tomcat instance with multiple apps? Mikko Pukki wrote: Hi, I have Tomcat installed on a server that already has Default Website configured for other use and I cannot use it to redirect to Tomcat. So I created another website that should listen to port 80 and authenticate users via AD authentication. After authentication it should redirect requests to Tomcat. Previously I have done such installations with one difference. I have been able to use Default Website and generally there have been little or no problems. However with this installation it doesn't work. System is Windows Server 2003, IIS version is 6, tomcat version is 5.5.16, ISAPI redirect version is 1.2.26. I did not use compatibility mode for IIS 5 and first I got 404 (or maybe 403 or something) from IIS, but I figured out that it was because of rights to read and execute dll. I corrected them and now IIS returns internal server error. Both Tomcat and ISAPI redirect filter start ok. Filter has a green arrow in front of it and I can use web application directly from port 8080.

Re: tomcat6 + proxy issues
I would seldom dare to differ with Mark with regards to Tomcat issues but in this case, I prefer mod_AJP for its more predictive behavior compared to mod_HTTP. Tomcat AJP's connector simulates almost the same behavior as Tomcat's HTTP connector. So the all important request headers will look the same. Some of the differences in behavior when you use Tomcat HTTP as a proxy instead of AJP: 1)remoteAddr resolves to whatever host Apache connects from to Tomcat. So you have to retrieve the actual remote address from the raw headers. 2)scheme will always be HTTP 3)serverPort will always be the Tomcat HTTP port (so you would need to edit server.xml and add the proxyport value) 4)many applications construct links from the above headers mentioned and you can see the problems the inconsistent behavior creates. Unless mod_proxy_ajp is far inferior to mod_proxy_http in terms of stability (which has not been noticeable from my experience), I would choose mod_proxy_ajp for the consistent behavior it provides. Mark Thomas wrote: Markus Schönhaber wrote: Mark Thomas: Actually, mod_proxy_http is usually a better choice than mod_proxy_ajp Could you please explain a little further? Since at one site I'm using mod_proxy_ajp I'm interested in what the advantage of switching to mod_proxy_http might be. Generally, and YMMV, mod_proxy_http is more stable. This is only a generalisation though. I have used mod_proxy_ajp in the past without any problems.

Re: I WANT Tomcat to die when a given servlet fails to initialize
If possible, you may consider a monitor or cron in a separate process.
It checks the state of the servlet by making
a HTTP GET to it; depending on response, it could initiate the
SHUTDOWN command to Tomcat.

Yeah, that was what I thought. Apps aren't supposed to do that. But in my

of parameters required by my app, because the one of the systems I'm

There isn't a clean way for webapps to shut down the server because they're
not really supposed to do that. :-)
If you thrown an UnavailableException from a servlet's init method, that
servlet won't run.
If you do app initialization in a ServletContextListener and throw an
exception from the contextInitialized method, the webapp won't run.
But in both these cases the Tomcat server keeps running.

basically a straight java application running inside of a web server.
The reason it runs in a Web server is because there is one subsidiary
use case that uses HTTP Gets to fire actions in the application via a
servlet. No other applications are served off this web server.
The non-web application's main() is the servlet's init(). If this
servlet cannot initialize there is no point to keeping Tomcat running
and it would in fact make monitoring easier if it were not running.
Is there any easy way to achieve this in Tomcat?

Yes you will have to edit the server.xml as you are trying to specify contexts off of Tomcat's default directory. First of all I do not recommend putting Java code in the same public_html directory used for processing other resources by Apache. Apart from being less than elegant, there are some inherent security risks involved with this approach. I am assuming it is a single instance of Tomcat shared by multiple users?

Re: BLACK ZONE alert on Stopping Tomcat Server
Hi Ghulam, Virtuozzo, is an OS level based VPS. Which means available system resources are shared between the VPS. During Shutdown, a Java process is created; this in turn utilizes a burst of RAM. So at that moment you have 3 JVMs running - TomcatA, TomcatB, and ShutdownA. That 3rd JVM may be stretching the available resources on your System. Now after TomcatA is completely shutdown, when you go to shutdown TomcatB, at that particular moment you have 2 JVMS (TomcatB,ShutdownB), which your system is able to easily handle. It is essentially a matter of available system RAM. You may want to increase the RAM.

Re: Configuring one webapp in 2 instances, system properties
Bas Schulte wrote: Hi, I tend to agree with both you and Chuck. However... ;) We're on a budget so separate servers is a no-op. Running multiple instances of Tomcat, with it's own start/stop script and it's own location for config files/libs etc. won't allow me to continue using debian's package management (I can already hear my sysadmin barfing at this solution). BTW, I do use this solution for activemq (there's no debian package for that ;)) and that's working fine. Using a Tomcat build obtained directly from tomcat.apache.org will enable you to easily run multiple installs. There in lies one of the many problems and limitations with the Linux Distros as they try to globalize the Java environment on a system Such conventions work great for scripting languages like PHP and Python. Since Java applications are usually dependent on a specific version of app server, jvm, and library, that way of thinking leads to unnecessary problems. The solution of building instance-specific war's using ant would work but my current skills (combined with my deadline) fall short. I've done ant scripts by hand but currently use NetBeans as my ide and haven't figured out how I can combine those two things. I'll reconsider things, based on your input. Thanks.

We don't have many hard stats about connections expected etc, so we want to start with a default configuration and memory allocation that will ensure all apps involved will have a decent chunk of the memory to work with, but not too little or too much. Thanks! Charl Hi Carl, First thing, Are you using a JDK and/or Tomcat distribution from the Centos repository? If not please download and install the JDK from java.sun.com and download and install Tomcat from tomcat.apache.org. Using the default configuration, is a good starting point to determine the optimized settings as you do not presently have any metrics.

Milanez, Marcus wrote: Chuck, Sorry if I haven't been clear enough, but we did have several situations in which such a thing happened in production.

We could just solve it decreasing tomcat's proccess initial and maximum amount of memory, that's why I've warned about it. I really apologize if I'm wrong, but is there another explanation for it? It sounds like in your case, you were allocating more memory to the JVM that was available from the system. Thus quite naturally when you lowered the allocation you encountered less problems. However if your application had indeed required the larger allocation, you would have experienced OutOfMemory. Point is, larger memory allocation is a good thing, but it cannot exceed what is available on the system. -- Regards Gabe Wong NGASI AppServer Manager JAVA AUTOMATION and SaaS Enablement http://www.ngasi.com NEW! 8.0 - Centrally manage multiple physical servers - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Is there a downside in doing that (separate work directories are ok) ?? assume that each tomcat instance points to a single tenant (on a multi-tenant app)? are there scalability issues? Yes you can assuming all instances have read access to the directory. Problem would be if instances write to the webapp directory. Really not sure what you are trying to achieve by sharing one webapp directory. I am curious how you can do a reasonable capacity plan for tenant sizes ranging from 1-10 users to 50-100 users to somewhere close to 500 users (memory to each instance, specific settings etc) What do you mean by users? If you are referring to instances, then it depends primarily on the memory demands of the application. The average application and application server instance requires about 128MB memory (RAM). Plus you need about 512MB to 1GB RAM available to the system for other usage. So for a 4GB RAM Server, you probably would be able to run 25 instances. Of course you have to consider other things such as database resource usage, etc. -- Regards Gabe Wong NGASI AppServer Manager JAVA AUTOMATION and SaaS Enablement http://www.ngasi.com NEW! 8.0 - Centrally manage multiple physical servers - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You will need to edit the file tomcat-users.xml and add a user with the role 'manager' if you want to be able to use the Tomcat Manager application. 3. You can start and stop Tomcat by running '/etc/init.d/tomcat5 start' (or stop,restart, etc). 4. Any Tomcat web application that you want to serve should be dropped into /var/lib/tomcat5/webapps/ 5. You can view your Tomcat website via http://yourserver.example.com:8080/. This webpage had some good instructions: http://www.weiqigao.com/blog/2007/01/14/tomcat_5_on_fedora_core_6_in_five_easy_steps.html I have often felt that Java developers, with their 'completely platform independent' system don't acknowledge that platform-specific knowledge is often a barrier to getting those Java applications up and running. The above steps make maximum use of the packaging work that Fedora and JPackage maintainers have done, and made this job very much easier for me than downloading the platform independent packages and working out their particular conventions etc. The concern that some of us on this list has with the various Platform specific distros, is that they are usually altered from the original Apache distribution. As soon as anything is altered, you have incompatibility issues. Most applications are developed and tested on the Apache distributions. You may not notice incompatibilities until you try to deploy a real complex application. That said, I am not saying one is right or wrong. It is just that just as Java has become relatively stable (predictable), there enters the various Linux based distros to add to the equation. Some of these distros do not follow the generally accepted JAVA programming principles (what is acceptable today). These distros usually follow the principles of traditional Linux based programming, such as PHP, Python, etc. And that is primarily to make packages globally accessible on the system. This is where the distinction between traditional linux applications and present day java applications are being missed. Most Java applications are dependent on a specific version of an application server, JVM, libraries, etc. Thus a one package for all creates issues. So moving forward, are Java Applications now to be built for a specific Linux distro, in addition to supporting the traditional purist java programming environment. Or is it that a new generation of java programmers under the Linux distro environment will give raise. Will there then be two camps or platforms? Or will the new generation become the standard. I say this because as I speak, more and more I see java questions on Linux lists instead of pure java lists. I know I do not usually rant, but this is an issue that needs to be addressed. -- Regards Gabe Wong NGASI AppServer Manager JAVA AUTOMATION and SaaS Enablement http://www.ngasi.com NEW! 8.0 - Centrally manage multiple physical servers - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So, does what I'm thinking sound do-able? I want to use NTLM authentication which is returning: DOMAIN\username but, then I want to check to see if that user is in a role (group) from LDAP. The format for that user is something like: Group dn: cn=manager,ou=groups,dc=mycompany,dc=com member: cn=username,ou=people,dc=mycompany,dc=com So, I want to go from my user autheticated as DOMAIN\username to finding out if that user is contained in my LDAP group. Does that sound possible? I guess I misunderstood your objective. You are not interested in manipulating the user name. You just want to check if the stripped user name is in a specific role? -- Regards Gabe Wong NGASI AppServer Manager JAVA AUTOMATION and SaaS Enablement a href=http://www.ngasi.comhttp://www.ngasi.com/a NEW! 8.0 - Centrally manage multiple physical servers - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Haven't tried it but you should be able to create a custom Realm by
extending the existing JNDIRealm and manipulating the user name,
probably by overriding the authenticate() methods.
The specific code my look like so:
import org.apache.catalina.realm.*;
import java.security.Principal;
import java.sql.*;
import java.util.*;
import java.io.*;
public class CustomTomcatRealm
extends JDBCRealm {
public synchronized Principal authenticate(String username, String
credentials) {
Principal p = super.authenticate(username,credentials);
if (p != null){
String newName = //whatever;
ArrayList roles = getRoles(newName);
p = new GenericPrincipal(this, newName, credentials, roles);
}
return p;
}
}
Check the syntax as it was just done on the fly.

Re: Tomcat 5.5 classloading behavior
Johnny Kewl wrote: What language is this guy talking ha ha. This has got to be for a thesis or something or its attempted suicide ;) - Original Message - From: Michel Betancourt [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Thursday, January 17, 2008 3:33 AM Subject: Tomcat 5.5 classloading behavior Hi, I am wondering if someone may be able to point me in the right direction here... after reviewing the J2SE spec, and the Servlet 2.4 Spec, its not too clear whether circular dependecies such as the one I am investigating below are legal or supported by Tomcat. Sun J2SE 5.0 classloader does not seem to support such initialization although the Tomcat classloader (v5.5) seems to an operation such as my example below. An exert of the Java specification states: 12.4.2, #3 If initialization is in progress for the class or interface by the current thread, then this must be a recursive request for initialization. Release the lock on the Class object and complete normally. You know what you should do... find a little custom class loader example on the web and run it through a debugger. They look simple but when you actually watch them work, and how reentrent the things are, this will hopefully all start to make sense. I think most guys havnt even started thinking about this... ClassCircularityError Wow! dont trap that in my code ;) This is what I think the normal system classloader, and the tomcat classloader when it comes to threads and reentrant code will behave exactly the same... the reason is that one class loader inherets from another and thus one can expect the behavior to be similar. The only diffirence is where the tomcat classloader will look for jars and class's. ie the same stuff is happening but when it comes time to find Your Class... it will look for it in the web-app, after that i think its much of a muchness. Thats different because outside of web servlets... class loaders are not allowed to work like that... they always ask the classloader above them if it has the class already, if not the parent class loader tries to find it, and ONLY if it cant find it, will the child classloader try and get it. If you watch a cl working you'll see that recursive request stuff happenning... and I'm no academic, in plain talk it just means that all those dependencies must be gotten out of the way, before the next thread can come in and ask for a class to load. So if A - B - C and thread one is busy with A, and thread 2 really just wants C it has to wait, because otherwise C would load... and then A would eventually get to it and it would load again because its already kicked off that recursive pattern. Then because C is waiting A will actually will have done it already... and the cl will then just say... thread 2, you lucky, class is loaded, you can go now. Normal CL or Tomcat no diffs. The other thing with these examples is that yes I guess it is possible to be surprised in the way STATIC variables are inited in complex class structure... but remember is LOADING, not INSTANTIATING the class, that comes later outside of the CL, so in most cases it not an issue one would even encounter. I dont think its possible to make an ClassCircularityError error with a modern IDE... I dont think it will let you compile the code Class A extends A so if you actually making these classes and compiling them I dont think its possible to simulate it without hacking byte code. be interesting to hear if anyone ever seen that. Thanks... I never ever thought about static variables before... and I've never seen it in practical code. ie I think in normal code a programmer may go what the... I thought static A was going to be 5, why is it 10, or whatever... and then eventually see the curcular RELATIONSHIP but I doubt that would cause an error. If its compiling... I dont think you can break a classloader... short of it just cant find the Jar interesting things these classloaders... good luck. If its practical stuff... I can help you a little, heavy specs and theory... you on your own ;) Nice analysis Johnny. To add to your thought (even though slightly off topic) - Yes there is a big difference between theory (specification) and practice (implementation). So it may be confusing for someone starting off from the theoretical side. -- Regards Gabe Wong NGASI AppServer Manager JAVA AUTOMATION and SaaS Enablement a href=http://www.ngasi.comhttp://www.ngasi.com/a NEW! 8.0 - Centrally manage multiple physical servers - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Alan Chaney wrote: Hi I am using Eclipse 3.3, tomcat 6.0.14, linux and Java 1.5 I have a web app which uses a JNDI data source. I wrote a very simple test servlet to access the data source and display some values from the database. First time around I used a local application context in /META-INF/context.xml. This worked fine. I then moved the Resource definition to a GlobalNamingResource in server.xml and that worked fine with a ResourceRef in context.xml. All well and good. I then renamed the app to ROOT with a path '/'. The servlet still responds and renders text correctly at http://localhost:8080/ but I get a javax.naming.NameNotFoundException regardless of whether the resource definition in context.xml or GlobalNamingResource in server.xml and referenced in context.xml. Needless to say the database content is no longer displayed. As a further test I exported the the war files as ROOT.war and deployed the war to a tomcat instance.

Re: Tomcat vs (other container) compatibility
That is more an Application design issue. In short, there are incompatibilities across the various containers. So if you are developing a cross-container application, the simpler it is the more chances of less re-configuration on different containers. However that may be contradictory as more requirements usually results in more complexities. Simple difference, is JNDI. The following are differences in calling a jdbc object called defaultDS: Tomcat/Jetty: java:comp/env/jdbc/defaultDS Orion(Oracle-OC4J)/Tomcat: jdbc/defaultDS JBoss: java:/defaultDS Weblogic: defaultDS And this is just one of the many differences. More off the top of my head, EJBs, Virtual Hosting configuration, etc. Some containers also require container specific XML descriptor in the application e.g. jboss.xml, etc. David Smith wrote: Michael wrote: Johnny Kewl wrote: --- HARBOR: http://coolharbor.100free.com/index.htm Now Tomcat is also a cool pojo application server --- - Original Message - From: Jacob Rhoden [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Saturday, November 17, 2007 1:40 PM Subject: Tomcat vs (other container) compatibility Hi, Just wondering if there is anyone who has been or is involved in cross JEE container work, how compatible are tomcat apps with other commercial apps such as OC4J, Websphere, BEA and so on?

Re: serving files through SSL
Roger Parkinson wrote:
I am trying to deliver some PDFs to the browser using my tomcat
application. It works, but not always under SSL and IE.
One file is a static PDF and it lives inside my war file. That works
just fine. The file is accessed using a url like /myapp/web/myfile.pdf
and that always delivers the file.
Other files are generated by the app and live in a configured
directory. They are delivered through a servlet that looks like this:
String mimeType = sc.getMimeType(filename);
FileHelper helper = new FileHelper();
InputStream in = helper.fetch(filename, m_dir);
response.setContentType(mimeType);
response.setContentLength(10115);
response.addHeader(ETag,W/\963288-1194247031062);
OutputStream out = response.getOutputStream();
byte[] buf = new byte[1024];
int count = 0;
while ((count = in.read(buf)) = 0)
{
out.write(buf, 0, count);
}
in.close();
out.close();
So apart from some minor fiddling with the contentType etc I don't do
very much. This works fine outside of SSL and it also works fine with
SSL and Firefox, but not SSL+IE.
Thinking it was a problem with headers I did some research and found a
lot of stuff about setting no cache etc. Tried it and it nothing made
any difference (except that I managed to break it). I have taken all
those out because the static file, the one I mentioned at first, is
delivering okay to IE over SSL so I don't believe there is a problem
at the IE end, or not one that cannot be overcome by getting my
response right at the server end.
I used TCPMonitor to sniff the headers using non-SSL and found that
the static file has this response:

So there doesn't seem to be too much going on there.
When I respond to the request for the dynamic file it looks like this:
HTTP/1.1 200 OK

...pdf file follows.
I am getting some cache headers added for free otherwise there is no
difference in the request.
Of course those headers may be making all the difference because IE's
message is 'cannot write the file to cache' which is a bit odd because
we've explicitly told it not to here.
Searching the web on this has a number of answers that suggest adding
those no-cache headers anyway.
So, does anyone know what I need to do to make the two responses
enough the same to stop IE complaining?
I am aware that I have faked the ETag and the length of the file and
that I need to do something smarter there, but I'll do that when it
starts working.
Version info: Tomcat 5.5, Java 1.5, WinXP SP2
Are you calling the dynamic PDF URL directly? For instance typing in the
URL directly in the browser?
The reason I am asking, is that for mixed responses from SSL requests,
IE puts up a warning, whereas FF does not.

Our application installs itself, tomcat, and a jvm, and then runs a bat file which registers the tomcat server, using our provided jvm. I _know_ this code works fine almost everywhere - it has been in use for years, on dozens of systems. However, we have a new customer, a 1/2 a world away, who has installed our application on a Windows Server 2003 box with 4 GB of ram that is using a Spanish Locale. The server is brand new - so its an almost perfectly clean install on windows. After we register the tomcat service - the service refuses to start tomcat. There are no useful error messages - just something along the lines of the service failed to start. I'm not sure exactly, because it's in Spanish.

So, to connect both we have an Asp.Net Connector on the one side and a Java Connector on the other side. If the user selects something on our application the JavaConnector is called which creates an URLConnection to a specific Asp.Net site. At the moment, the URLConnection is established with an empty username and password because we created a specific IIS user which is always the same for every request. Now, we want to use the integrated windows authentication, i.e. we want to know which user is currently asking. That's why we thought on NTLM authentication or something like that... But we didn't know how to get the credentials in the Java Connector to establish the connection with Asp.Net. What can we do? Is it generally possible to use the integrated windows authentication in Java with IIS and Tomcat? How? Can you give me some tips?

Re: Tomcat 5.5.25 takes 5 minutes to shut down.
Hi Hermansen, Check the solution in the following link: http://www.ngasi.com/ngasihelp/ngasiuserguide/tomcat_fails_shutdown_complete.htm Hermansen, Erik wrote: Hello! I'm running Tomcat 5.5.25 on SLED 10. I performed the installation of Tomcat manually, using the apache-tomcat-5.5.25 archive from Apache's website. Tomcat will start fine and operate as expected, but shutting down is unreliable and often takes about 5 minutes to complete. If I run the $CATALINA_BASE/bin/shutdown.sh script, it will return immediately without errors, but checking for the process (ps aux | grep tomcat) shows it is still loaded for a long amount of time after the script is called. On a different server with identical hardware and very similar tomcat installation, the shutdown script will bring Tomcat down in about 3 seconds. Reading through catalina.out, I find this error which corresponds to calling the shutdown.sh script: SEVERE: Protocol handler pause failed java.net.ConnectException: Connection timed out at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:171) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:158) at java.net.Socket.connect(Socket.java:461) at java.net.Socket.connect(Socket.java:411) at java.net.Socket.init(Socket.java:310) at java.net.Socket.init(Socket.java:154) at org.apache.jk.common.ChannelSocket.unLockSocket(ChannelSocket.java:49 2) at org.apache.jk.common.ChannelSocket.pause(ChannelSocket.java:289) at org.apache.jk.server.JkMain.pause(JkMain.java:681) at org.apache.jk.server.JkCoyoteHandler.pause(JkCoyoteHandler.java:163) at org.apache.catalina.connector.Connector.pause(Connector.java:1032) at org.apache.catalina.core.StandardService.stop(StandardService.java:48 9) at org.apache.catalina.core.StandardServer.stop(StandardServer.java:734) at org.apache.catalina.startup.Catalina.stop(Catalina.java:602) at org.apache.catalina.startup.Catalina.start(Catalina.java:577) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl. java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAcces sorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:295) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:433) Sep 19, 2007 3:11:55 AM org.apache.catalina.core.StandardService stop INFO: Stopping service Catalina Sep 19, 2007 3:11:56 AM org.apache.coyote.http11.Http11BaseProtocol destroy INFO: Stopping Coyote HTTP/1.1 on http-8080 Sep 19, 2007 3:11:56 AM org.apache.catalina.core.AprLifecycleListener lifecycleE vent INFO: Failed shutdown of Apache Portable Runtime I've found a couple similar cases where people had this problem.

Re: Vmware and Tomcat 5.x 6.x
Mitesh, The most important thing with regards to the JVM, is available memory. Of extra importance in this case is the amount of memory (REAL/PHYSICAL) allocated to the Virtual Environment (VMWare). That said, you also need to determine the Memory Heap usage of each of the JVM instances. Sluggishness usually indicates a memory shortage. At that point SWAP consumption increases. As you would image disk swap would be much slower than real memory. Besides sluggishness, SWAP usage may increase the chance of disk failure because essentially you are using a 100% of resources. In short compare the total Memory Heaps of all the JVMS to the total memory allocated to the Virtual Environment of the VMWare instance. Mitesh Shah wrote: Thanks Chris for reply. Clarion is SAN, so all are data and OS partitions are on SAN. Whole server works fine but our application works using tomcat and I have installed around 20 instances of tomcats on one virtual machine (2.66GHz and 4GB RAM). On similar line, does JDK takes advantage of two CPU compared to one CPU? I can reconfigure Swap file on separate disks than OS disk and see if it performs better. Please let me know if above info helps in understanding issue better?

There are too many variables to monitor and looking for some path to follow. Is the whole server slow, or do you notice that certain operations are slow? I was hoping to get some input as if anyone is aware of such issue of vmware and tomcat. AFAIK, there are no Tomcat-specific vmware issues. However, there could be some problems with the JVM in general that you might be coming across. For instance, if you are using a source of randomness that blocks when used through the virtual environment, that might cause a problem. Also, if you are using non-native disks (meaning a big file on the host OS that holds the entire filesystem for the VM), you may experience some slowdown, there. I'm not sure what Clarion is... could that be a problem at all? - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFG+DOF9CaO5/Lv0PARAtSKAJ0T6KHaEBu8WC6c9QSnea0QWtj/8QCguIhp VSqAodugC0GLy8LRk5In52I= =nMgC -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Regards Gabe Wong Private JVM JAVA Hosting Automation http://www.ngasi.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]
