Tomcat auf MS Cluster?
Hello, we're planning to run Tomcat Apache 5.0.28 on a MS Server 2008 R2 64Bit Ent. Failover Cluster. Does anyone has productive experience on that? Does it work, How good does it work, .? Things to be aware of? (If required, Tomcat 6.* is possible but we'd prefer Tomcat 5.0.28 to start this project because we've most experience and know how with that one. Updating Tomcat later on is no big deal) Thank you for any inputs! // Stefan

Hello, thank you for your reply but I do not manage to get my desired result. We have several axis*** servlets installed in /webapps of Tomcat 6.0*. (Let's call it axis1 to axis100 for this explanation.) In Tomcat 5.0* we had different contexts with loggers defined in server.xml, thus the stdout was redirected to the files configured in this loggers. This configuration is not proposed and also not supported in Tomcat 6. == We have tried a lot of different things but I never managed to redirect my stdout from localhost.Date.log to a localhost_axis1.Date.log file.

Denial of Service / MaxThreads
Hello, we are currently running a Tomcat 5.0.28 on Java 1.5.0.11 with a MaxThreads Configuration of 500 threads.

64bit Server + JDK 1.5 (64bit) + Tomcat 5.0.28?
Hello, we have to increase the number of maximum threads on our 64 bit server Windows 2003 server. At the moment we are running Tomcat 5.0.28 on a JDK 1.5 32 bit because of historical issues and we can serve about 500 threads without having memory problems. If we increase maxThreads size over 500, we get memory errors. (Heap Space is configured to 800 MB maximum) Now we are thinking about switching to the 64 bit JDK to avoid these memory problems. BUT as far as I know, tomcat 5.0.28 is compiled for 32 bit. So, do we get any advantage from replacing the 32 bit JVM against the 64bit? We'd like to avoid a Tomcat update at the moment!

AW: Service available for HTTPS only? (no HTTP)
Hello, thanks for answering. In my web.xml file I don't find any entry corresponding my service. It seems to be the default web.xml file provided by Axis 1.3. I did some researches on your keywords transport-guarantee and CONFIDENTIAL but I could not find something usefull. In my point of view, it will probably be the easiest way to install two Axis-servlets in the Tomcat. One for HTTP and one for HTTPS. Then I can deploy the services either for HTTP or for HTTPS. Does anyone know how I can configure my Axis servlet to only handle HTTPS requests? Is the difference between HTTP and HTTPS forwared from Tomcat to Axis? Does it know it?

Service available for HTTPS only? (no HTTP)
Hello! Situation: At the moment we are working on following environment and not able to make any updates with the next time: Win2000 Workstation Tomcat 5.0.28 Axis 1.3 JDK 1.5_11 Until today we had only one HTTP connector configured in Tomcat to provide some (Axis) SOAP Services. All of them work fine! Target Solution We need to use HTTPS (SSL) for one of these services instead of HTTP. We configured a second connector in the Tomcat und followed this instruction: http://www.torsten-horn.de/techdocs/ssl.htm The service XY is now available via HTTPS and it works fine! Problem: The service XY can still be called via HTTP (without SSL). == Does anyone knows a trick to avoid calls via HTTP to this service? We can not remove the HTTP connector because some other services on this server have to be available with HTTP.

IOException while loading persisted sessions / java.lang.OutOfMemoryError: Java heap space
Hello,
we are running a Tomcat 5.0.28 on W2k Server with 2 GB RAM and JVM
1.5.0_11-b03 which is mainly used as application server for (Axis-based)
SOAP Services.
From time to time our Tomcat blows up to use almost the whole available
RAM and finally it crashes.
In the logfile, we find the following:
- IOException while loading persisted sessions: java.io.EOFException
java.io.EOFException
at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source)
at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown
Source)
at java.io.ObjectInputStream.readStreamHeader(Unknown Source)

at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown
Source)
at java.io.ObjectInputStream.readStreamHeader(Unknown Source)
at java.io.ObjectInputStream.init(Unknown Source)
[]
After that a restart of Tomcat is not possible and the following lines
can be found in stdout.log:
SEVERE: An exception or error occurred in the container during the request
processing
java.lang.OutOfMemoryError: Java heap space
Exception in thread http-16302-Processor151 java.lang.OutOfMemoryError:
Java heap space
28.11.2008 20:08:47 org.apache.coyote.http11.Http11Processor process
SEVERE: Error processing request
java.lang.OutOfMemoryError: Java heap space
Only a reboot of the whole server fixes the problem and tomcat works
again as exptected.
I have read in some forum, that we could clean the
${catalina.home}/work/Catalina/localhost/ directory to enable a tomcat
restart without server restart.
We haven't been able to try that yet, but that fixes only the symptomatic
not the problem.
Does anyone have an idea/experience where the problem comes from? Something
to do with memory / session management?
Extract from configuration / status, if needed:
Free memory: 10.42 MB Total memory: 63.56 MB Max memory: 63.56 MB
Max threads: 150 Min spare threads: 25 Max spare threads: 75 Current thread

So, the machine itself has enough memory, it's just that the way Tomcat is started, the JVM under which it runs does not receive more than 64 MB of Heap space to run, which is really low for a server. The fix is probably simple ; you need to increase how much heap memory Java can play with. Since you are running this under Windows, I presume it runs as a service, and probably in your Tomcat/bin directory you have 2 files : tomcat5.exe and tomcat5w.exe. tomcat5w.exe is a GUI application, which allows you to set the parameters under which the JVM of Tomcat is started. Double-click on it, select the Java tab. At the bottom of that tab, there are 2 input boxes : Initial Memory Pool and Maximum Memory Pool. Enter 256 in each of them, and click OK. Then restart your Tomcat service and see if you still get the same problem. These parameters are the equivalent of specifying the -Xms256M and -Xmx256M on the java command-line that starts Tomcat. - 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]

Tomcat is a Java application. Java uses a lot of memory. That's a fact of life, better get used to it. The heap memory that you configured earlier, is only part of the memory used by Java and Java applications. Also, depending on the machine and the OS, I am never quite sure whether 128M means bytes or words.. Think of it this way : Java is a Virtual Machine, running under your OS. It insulates the Java applications from the underlying OS and hardware. That is why Java applications are multi-platform : they carry their own platform with them. The price you pay for that is memory. Another thing : under Windows and with the standard installation as a Service, don't get fooled by the name tomcat.exe. That is only a wrapper program to make it run as a Windows Service. Underneath, it really starts the Java Virtual Machine (java), and the JVM then starts the application (Tomcat). - 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]
