Re: How to monitor performance of tomcat
Hi, I increased the Heap & PermGen memory as per trail mail but the performance seemed to deteriorate. On the day I increased the memory in the morning, the system hung 3 times in the day whereas the maximum times it has got hang before is 2 times in a day. I changed the memory settings for Heap & PermGen back to before when it hung again the next day, I reverted to the old memory values. The catalina.out showed the entries like below when I monitored it twice after the system hung with the new memory values: [ 22-May-2014 03:15:40 ] [ TRACE ] [http-30080-56] [ CHECK SESSION ] : Inside doInit Method May 22, 2014 3:16:14 PM org.zkoss.zk.ui.impl.UiEngineImpl handleError:1351 SEVERE: >>org.zkoss.zk.ui.UiException: org.jboss.remoting.InvocationFailureException: Socket timed out.

Thanks Ognjen for your reply. My reply was intended to 2 different people hence it repeated but anyway I would try to take care on this. So now it is clear from your answer that catalina.sh is called from startup.sh in a default installation.

Re: How to monitor performance of tomcat
Hi, There is a correction as JAVA_OPTS variable is defined in catalina.sh under $CATALINA_HOME/bin and we use $CATALINA_HOME/bin/startup.sh to start tomcat. $CATALINA_HOME/bin/startup.sh has the code like below , -- PRGDIR=`dirname "$PRG"` EXECUTABLE=catalina.sh # Check that target executable exists if $os400; then # -x will Only work on the os400 if the files are: # 1. owned by the user # 2. owned by the PRIMARY group of the user # this will not work if the user belongs in secondary groups eval else if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then echo "Cannot find $PRGDIR/$EXECUTABLE" echo "The file is absent or does not have execute permission" echo "This file is needed to run this program" exit 1 fi fi -- I had changed catalina.sh in our development environment like a week back and want to implement it in the production environment but I got this doubt.

Re: How to monitor performance of tomcat
Hi, I had another point to add in this other than the reply sent by me in the earlier mail is that if the JVM crashes as pointed out by you, would a JVM process get started when Tomcat is started. Also, how to check if 2 processes are sharing a common JVM. The 2 processes referred to with the context of our environment would be JBoss & Tomcat. I hope my query is clear. Requesting a reply.

RE: Tomcat dependency on application server
I have 1 observation. In our developmental environment, I killed the Tomcat process and started the Tomcat it worked. But in the production environment, starting Tomcat was not enough and I had to restart JBoss & Tomcat in sequence for Tomcat to be up. Could it mean that JVM is crashing or something because of OOME in Tomcat. I could try to increase the heap & Permgen memory in Tomcat, would that help? Requesting a reply.

Tomcat dependency on application server
Hi, We have JBoss as the application server & Tomcat as the web server in our production & developmental setup which is on Red Hat Linux 5.X. We have tomcat 6.X. My query is that if I need to restart tomcat, do I need to restart JBoss & Tomcat both or just restarting Tomcat would be enough. I am asking this query because I had killed the tomcat process using kill -9 and while restarting tomcat it was not starting but when I killed JBoss & tomcat and then restarted, Tomcat was up. I hope my query is clear whether Tomcat is dependent on JBoss.

Read the comments at the top of bin/catalina.sh to see what the difference is. Also, you should set these environment variables in bin/setenv.sh (which you may have to create) instead of modifying startup.sh directly.

If the problem is GC-related, then the only conditions under which things will improve by increasing memory are if you were running right under the heap ceiling you had imposed upon yourself and GC had to run a lot in order to keep up. Remember that GC-time is related to the number of useful references in the heap, so if you have a large heap with lots of long-lived objects, GC will work "harder" (to a point, with generational GC). > There is another thing I wanted to try.

RE: How to monitor performance of tomcat
Thanks Chris for your answer. I researched a lot and want to try out an option for OOME: The JAVA_OPTS variable in $CATALINA_HOME/bin/startup.sh has the value as: JAVA_OPTS="$JAVA_OPTS -Xms1303m -Xmx1303m -XX:MaxPermSize=256m -Dcwom.bl.ip=127.0.0.1 -Dcwom.bl.port=1399" I checked for free space on the VM instance with Red Hat Linux as the OS on which the Tomcat is hosted with a total memory of 19 GB, I found that there is around 8 GB of free space in the server. I am planning to increase the memory allocation for Heap size and PermGen size to almost double as below: JAVA_OPTS="$JAVA_OPTS -Xms2048m -Xmx2048m -XX:MaxPermSize=512m -Dcwom.bl.ip=127.0.0.1 -Dcwom.bl.port=1399" I hope, this should avoid the hang-up issues where Tomcat does not seem to respond. I plan to implement this in the UAT environment at first and see how it goes. There is another thing I wanted to try.

It sounds like you have all kinds of problems: 1. Bad performance under unspecified conditions 2. Application hang under unspecified conditions 3. catalina.out file grows quickly, may fill filesystem 4. Long timeouts on the server-side during some unspecified operation (I don't know what an InvokerLocator is) 5. OOME It seems to me that you should focus on one of these problems (probably the OOME) and get that fixed, first. You may find it is the root of all other problems. This community can only help you so much with so little information. You may have to hire someone to help you through this process. - -chris > -Original Message- From: Jeffrey Janner > [mailto:jeffrey.jan...@polydyne.com] Sent: Monday, April 21, 2014 > 7:26 PM To: 'Tomcat Users List' Subject: RE: How to monitor > performance of tomcat > >> -Original Message- From: Randhir Singh >> [mailto:randhir.si...@sterlite.com] Sent: Monday, April 21, 2014 >> 5:17 AM To: Tomcat Users List Subject: RE: How to monitor performance >> of tomcat >> >> Hi, >> >> I wanted input from the experts on my query below that the port >> 8891 does not respond when the command, >> >> jconsole 10.101.17.79:8891 >> >> is issued when the application hangs and stops responding. >> >> Requesting inputs so that the root cause analysis of this issue can >> be found out. >> >> Regards >> > Randhir - Your actual first request in this thread was apparently a > request for opinions on monitoring tools.

RE: How to monitor performance of tomcat
Thanks a lot for your detailed reply. The JAVA_OPTS variable in $CATALINA_HOME/bin/startup.sh has the value as: JAVA_OPTS="$JAVA_OPTS -Xms1303m -Xmx1303m -XX:MaxPermSize=256m -Dcwom.bl.ip=127.0.0.1 -Dcwom.bl.port=1399" I checked for free space on the VM instance with Red Hat Linux as the OS on which the Tomcat is hosted with a total memory of 19 GB, I found that there is around 8 GB of free space in the server. As per your inputs, I am planning to increase the memory allocation for Heap size and PermGen size to almost double as below: JAVA_OPTS="$JAVA_OPTS -Xms2048m -Xmx2048m -XX:MaxPermSize=512m -Dcwom.bl.ip=127.0.0.1 -Dcwom.bl.port=1399" I hope, this should avoid the hang-up issues where Tomcat does not seem to respond.

The end user experiences this usually as a hung system. It might eventually come back or it might end up with a different, more severe, OOM error. There are lots of various causes for this: too small memory allocation; too much load; an activity generating a lot of objects, most of which persist for a long time; memory leaks; or a combination of the above. How to address it? a) Profile what parts of the app are being used with this occurs and have the dev team look at what could be causing the problem. There might be a better way to perform the action requested. b) Increase the available memory (double it or more). This is only a band-aid and you may still have the problem, but less often. Have the dev team look for memory leaks. c) Anyone else with ideas?

Here is what I've usually found when Tomcat stops responding and even the monitoring port is unreachable via jconsole and other tools: Your JVM has crashed for some reason. At this point, you need to refer to the Tomcat logs, your application logs, etc. in order to find the root cause. If the JVM is still "running", try taking a couple of thread dumps and review them to find your root cause.

Re: How to monitor performance of tomcat
Hi, I have come across a point which could be a reason, the catalina.out file has become 13G which came to notice when we were analysing space crunch on the mount point in which tomcat is located. Further to this, there is some log rotation which is happening. But, what should be the steps to check or to introduce log rotation otherwise. Request you to please revert as it is urgent. I would be waiting for a revert.

How to monitor performance of tomcat
We have an application which has JBoss as the application server with Tomcat as the web server, our application has Oracle 11g as the database. I would give some further background to the issue we are facing, since the last 1 1/2 months, the application slows down. Sometimes it comes back to normal, specially on week-ends. But other times we restart JBoss & Tomcat to bring back the application to normal. We have been using jconsole to monitor tomcat like jconsole 10.101.17.79:8891 which monitors our tomcat for a work order system. If the memory usage does not show spike and shows constant reading, the GC button is clicked to invoke the garbage collector. I checked out on the net and got some clue as below: 1) Javamelody - It seems to be a 3rd party tool which is not recommended. 2) There is a command mentioned to see the admin console, http:/// but it is not displaying the required page. Please give your inputs whether jconsole should be a help in the right direction or some other way to monitor the performance of Tomcat.

How to deploy Java application into Tomcat in Linux
Hi, As per my understanding, the steps to deploy a Java application on Tomcat (5.X/6.X) in Linux would be as follows: 1) Install Tomcat on Linux 2) Add a host entry in $TOMCAT_HOME/conf with the syntax like- - reports.fion.co.in The above code would assign the host name to access the URL, gives the location of the web application pointed out by appBase & context path. 3) Start Tomcat.

André, if I'm not mistaken, you're quite new to the list. I've seen lots of similar posts here, which I consider being a complete neglet of respect to the people contributing to this list. They always follow the same principle: - You can sense that they've no clue about Tomcat / Apache / name-the-topic - Their questions can easily be answered by referring to the docs - They always have a "requirement" from a client to solve an issue - Often, not always, you'll find the word "ASAP" within their post - At least to me the impression occurs, that those guys consider the list as some free-of-charge-solve-my-problems-thingy - On top, usually they don't provide any useful information which helps solving their problem - And most certain, after their problem is solved, you' ll never see them here again contributing - I don't care about the whereabouts / wherefroms of any poster of this list, and I'd give the same answer to anybody showing the same attitude, wether they're Indian, Chinese, German, US, UK, even Belgian ;) - I'm a cosmopolitan, I'm Europena, I'm German, and I just don't care where somebody has been born & bred nor where somebody comes from. What I do care about is, that some freeloaders seem to take the contribution of this list-members for granted. And yes, I've heard it so many times from prospects: "Well, you've offered a great solution, but I can get the same thing cheaper if I take company xyz". Sure, company xyz has some offshore-locations, and a year later meeting the same "ex-prospect" again, they tell me that either - either the project went down the drains - budget was quadrupled ... Now tell me: If you hire a company to, say, maintain the engine of your car? Right: You expect, that this company has employees knowing how to do this. What's happening here is, that the "mechanic" doesn't have any clue of your car, goes to a pub where he knows the mechanics from other companies are hanging out and asks them get his job done - for free, of course. Maybe this example is a bit over the top, but I guess you've got the meaning. Therefore, again: - I'm a great fan of a *fair* competition - I believe in Open Source and sharing of information (you got it: "sharing" works only both ways!) - Least I'm anything liek a racist - ask my friends and colleques in [ enter_any_country_here] On Tue, Feb 3, 2009 at 3:12 PM, André Warnier wrote: > > Yes, but the correct word is "ridiculous". > I'm also not joking about language-issues.

Now that starts sounding a bit peculiar. What do you mean by "offshore" ? Anyone not in the same particular country where you presently are ? (because I don't think I am either) And I thought this was a global Internet forum, dedicated to helping Apache Tomcat users worldwide, irrespective of origin, culture, nationality, beliefs.

I've been wondering about the same thing reading some posts, but the presumed cultural or geographical origin or off-shoreness is not well-correlated to the (lack of) quality of the posts. > > I don't have any problem with a fair competition and sharing > information, But the way you write, makes it sound as if you do, because the only element you had to categorise this OP as unfair, offshore or whatever was his name. If I go by the names alone, I'd bet that quite a few of the Apache Tomcat developers and helpers on this list are not direct descendants of the Mayflower crew either.

the java and tomcat version is same in the old and the new. We had copied $JAVA_HOME also from the old to the new.

I highly recommend hand configuring tomcat rather than just copying config files though. The review is good practice and config files -- particularly server.xml -- have changed over time. The thing that would concern me more is if tomcat and/or java version changes from old to new. If that's the case, you will have to test your app in the new environment before going live. --David Randhir singh wrote: > Thanks, for your answer.
