Re: problem in running Jconsole remotely --Connection refused
Dear Subhrajyoti, I am facing problem in running Jconsole remotely . In my machine from where I am running Jconsole I have jdk1.6...I am trying to connect to TOmcat6.0.18 running on a windows 2003 server machine(with JDK 1,5) ...I have a batch file with the following contents : When I execute the batch file Tomcat is starting okay. But when I am trying to run Jconsole to connect to the Tomcat , I am always getting a connection refused error. I think I have set up the parameters correctly here ? Apart from this all the .bat files that comses bundled with Tomcat6.0.18 are kept same. I can ping the server from my machine without any problem . JConsole remotely is a problem. Recently I have started work on an on- line monitoring tool that allows you to monitor memory and threads without any firewall trickery. If you register at http://java-monitor.com, you can download a small WAR file (~35kB) that will collect the memory stats. Read more on http://java-monitor.com/install.html Oh, it also does thread deadlock detection, but that's just a freebie. ;-) -- Kees Jan http://java-monitor.com/forum/ [EMAIL PROTECTED] 06-51838192 The secret of success lies in the stability of the goal. -- Benjamin Disraeli - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
problem in running Jconsole remotely --Connection refused
Guys, I am facing problem in running Jconsole remotely . In my machine from where I am running Jconsole I have jdk1.6...I am trying to connect to TOmcat6.0.18 running on a windows 2003 server machine(with JDK 1,5) ...I have a batch file with the following contents : When I execute the batch file Tomcat is starting okay. But when I am trying to run Jconsole to connect to the Tomcat , I am always getting a connection refused error. I think I have set up the parameters correctly here ? Apart from this all the .bat files that comses bundled with Tomcat6.0.18 are kept same. I can ping the server from my machine without any problem . set path=C:\PROGRA~1\Java\jdk1.5.0_05\bin set JAVA_HOME=C:\PROGRA~1\Java\jdk1.5.0_05 set JAVA_OPTS=-Xms1024m -Xmx1024m set CATALINA_OPTS=-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port= -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false SET CATALINA_HOME=E:\AppServer\tomcat\tomcat6.0.18 CD bin startup BTW there is no problem in connecting locally ...But I don't want that because I want to monitor TOmcat while a load test is on . So resources should be used sparingly in the server . Please suggest the way to generate any extra debug info that I can get to see why this connection refused error is happening .

Re: problem in running Jconsole remotely --Connection refused
Have a look at this thread: http://markmail.org/message/r4lwb4ipa6ssaawy The second port is probably blocked by a firewall. I am not a system guy and have no idea about firewalls..It is a default Windows 2003 Server set up .So I am assuming that whatever is there is there by default and no further tweaking to the server was done . So do you think the default configuration can block the dynamically alloted port ? The Listener I refer to is now in svn. See: http://svn.apache.org/viewvc?rev=699523view=rev So how woud I make it to work with the existing tomcat 6.0.18 ? How long would I have to wait to get it out of the box ( ie 6.0.19+)?

Re: problem in running Jconsole remotely --Connection refused
No idea. Use netstat to find out what port it is using and then talk to your network support folks. When the Tomcat server has started with the JMX agent attched to the JVM( Which I suppose it does) , I did a netstat at the server machine and nowhere I saw any entries with the port that I mentioned during startup of the JVM( with the -Dcom.sun.management.jmxremote.port=)...Should I netstat at the client machine also ( where Jconsole is running)after staring Jconsole?
