Re: ajp over ssl
Problem with IPSEC / ssh tunnels between two machines is that if someone compromises one machine, then you've made their life 500% easier getting to the next one. Good stuff to connect your home LAN to office LAN, but I wouldn't.. I had trouble with the same thing, and the easy solution I found was to ReverseProxy apache to Tomcat and in the proxy directive to simply say pass it on to https://, and configure Tomcat with it's keystore and hey presto. Deviation from connector scene I know, but it works perfectly. Pete. Michael Jürgens wrote: Ruth, Brice wrote: That's the best idea I can think of, too. With SSH tunnels using public key authentication, you can set it up so that the tunnel is setup from a system script, without user intervention. But what if the tunnel breaks?

Admittedly I didn't look all that hard -- maybe someone who did development work on the connectors can anwer. I can suggest what I did which is setup a tunnel (SSH tunnel in my case) between the two machines. Then they (the servers) can talk all they want and it covers all services routed through the tunnel -- not just apache and tomcat. Ipsec would work just as well I suspect.

Is there any reason that your web-application (on Tomcat) needs to be aware of the SSL security? You can find documentation on securing Apache via SSL on the main Apache site (httpd.apache.org). And communicating betw. Apache and Tomcat via JK has abundant documentation as well. Good luck! No I want to connect an apache webserver over internet to a tomcat server. So far I have no problem.

Tomcat 5.0.19 dies unexpectedly
Hi, We've been using Tomcat 5.0.19 for a long time with no problems, yesterday, whilst the application was up for almost 3 hours, catalina.out suddenly reported that Address already in use:8080 and the server process died. On other server, we do have multiple Tomcats, and this normally happens if we make a mistake and put the same HTTP port on two different Tomcats, and it fails exactly like this, but in this case it failed without prompting after 3 hours. We did have a seperate Tomcat 5.0.25 on port 8081, also Apache 2.0.50 on port 80. Dell Poweredge 2650, RedHat ES3. Any ideas are welcome ! Please see the error below.

Re: scripts for Workers
If you are talking about workers on the same machine, simply hit each startup.sh et al in turn. If you are talking about workers on many different machines : (On a central PC) Do an array of server IP's with a common username (i.e. tomcat) - (and tomcat directory - i.e. /usr/local/tomcat). The workers must have the ssh key of the central PC in each known_hosts file. Simply iterate round your workers array (for each IP) and use ssh to execure a remote command, $IP $TOMCAT_HOME/bin/startup.sh Pete. Boulay Arnaud wrote: Hi !

Re: AW: How to increase memory
CATALINA_OPTS=%CATALINA_OPTS% -Xms1024m -Xmx2048m note quotes (need that ammendment in Linux, try something similar for Window$e if needed..) Also, if you put a -Xloggc:/usr/local/tomcat/logs/gc.log (check syntax with java -X help) do Xloggc before and after changing memory size, then have a look if gc cycles change. You can use HPjtune to graphically see the cycles. Do you need to include the -server in the above string depending on your JVM ? You want 3-10% max of cpu time in gc and periodic cycles. I'd say start from very low initial heap with a decent max setting and look at gc. Anyway, 1GIG initial heap is massive - why u need it so big? I've got a very intensive app, and initial heap of 80m, max heap of 768 works fine. Remember, it's a combination of initial heap and max heap that determine your apps gc cycles. Try look at using incremental gc ?? Whilst you are testing your app, check cpu usage to see it's not being killed, if so get better box. Pete. Gunnar Pörschke wrote: Where do I have to add this?

Re: Tomcat process memory growth
Question regarding tomcat connectors to apache : I've experimented with jk jk2 etc, but always found performance to be degraded noticably when using apache in front of tomcat with connectors, but with tomcat alone it's fine. I've done a reverse proxy from apache to tomcat and that flies, so have other people experience the same with connectors ? I know connectors are good for load balancing, but connecting a single apache to a single tomcat performance wise, does it work Pete.

Apache2 mod_ssl cert error to Tomcat
Hi. I am trying to get Apache to reverse proxy (thru SSL) to Tomcat5 on a different box.

Apache2 encryption to Tomcat5
Hi, I've got Apache2 reverse proxing to Tomcat5 on a different box (Linux's), accepting SSL to Apache and using the SSLProxyXXX directives to terminate the SSL connection. What I need is to provide a low grade encryption between the Apache2 and Tomcat5 boxes. I know in Tomcat conf to uncomment the SSL HTTP/1.1 connector, using the SSLServerSocketFactory, but what I can't work out is how to get Apache to forward requests to this connector, encrypted. The reverse proxy is nice and simple, so I hope I can get this to work without having to try jk2 connectors. Any ideas would be great.

Tomcat 4.1.29v5.0.18 performance
I've just got my app load balanced between Apache 1.3 2xTomcat 4.1.29, JK, SunJDK1.4.2, all seperate boxes. I have set heap site (JVM settings) same as my Tomcat 5.0.18, and guessed minProcessors=100 and maxProcessors=300 for server.xml's - config different to 5.0.18. It's appears about 3x as slow as a single 5.0.18. I have three questions re this: 1) Has any1 experienced this and found a solution? 2) If I can't get T4.1.29 up2speed, and want to loadbalance with T5.0.18 / Apache 2, do people actually use this in production without any major issues? 3) If I go point 2, then the only way I've found to provide loadbalancer redundancy for those versions is LinuxVirtualServer.

Tomcat / WebSphere Performance
Following up from my earlier post re Tomcat performance on different platforms, I have 3rd party results on comparing Tomcat and WebSphere on different platforms for their app, obviously I don't have intricate details about this test. Tomcat WAS Win 2K WAS iSeries Overall Average Response time 873ms 680ms22206ms Overall Trans Average Response 1610ms 1200ms - How does this compare to people's experiences, speed comparison, etc as per same application in different appservers / os's ? (Noting WAS=WebSphere app server 4.0.7), Tomcat *probably* 4.1.29. JDK for Tomcat unknown. Any comments would be greatly useful.

Page to page times (DB everytime) are incrediblely fast, basically instant even under 150 user load test. On the iSeries, we get over (live objects) 2million Vector object, 2million PCMLDocuments, and a whole host of other big figures. I used JProfiler on the app (Tomcat) and we get nothing like that. IBM seem now to say that we need to *dedicate* 2 processors, 4-6gig of RAM to continue to test the app on an iSeries (820). We are also totally patched up on the iSeries. Interesting figure is that when the iSeries/WebSphere hangs, we shut off the load test and it recovers after 20-30mins with a collected object gc figure of 25million+ compared to a normal 5million. The gc cycles also intermingle. GC cycle 19 starts, and GC 20 then starts before 19 has finished. I have collected loads of info - if you need anything else give me a shout. Regards, Pete.

If you're using stateful EJB's you may want to profile it first. Without knowledge of what the app does, my first guess is something in the app is eating up all the CPU and memory. If the app has been profiled aggressively and you know it's not the app itself, i would say install the app on JBoss and compare the performance. If you have hard numbers with the same app, it is much easier to get people to listen. you can also d/l weblogic and see how it performs. keep in mind weblogic has a limit of 10 concurrent connections, so if you need to load test with more than 10 connections, you'll have to smooze the BEA sales guys. You should be able to get them to give you a temporary one month license with unlimited connections, since they are trying to win customers from IBM. there are several old benchmarks comparing various servlet containers, which may or may not help. If you use ejb, those results won't do much for you. if you provide more details, you'll get better help :) peter lin Peter Stokes [EMAIL PROTECTED] wrote: Hi, I'm on a site where a third party application has been put on WebSphere 4.0.5 on an iSeries 820/V5R2.

Re: Urgent-Java webservers on iSeries and other platforms
Peter, Apparently we are fully PTF'd up, os, websphere, the works. Did your friend get it working or did they move platforms? If your friend whom had similar experiences could share them, it would be great to hear what they did. Anything would help because it's got to the point of IBM throwing RAM at us. I'm sure at this stage of the game we could try and get a finders fee from IBM! ;) (they're throwing RAM modules at 8k a pop for nothing so it's worth a go!!) Regards, Pete.
