Problem while connecting to remote HornetQ provider using JMX

m.carbone Aug 9, 2011 5:37 PM

Hi all,

I have a problem trying to connect a jdk 1.6 jconsole to a remote hornetq 2.2.5 server. I'm trying both the connect strings:

and

service:jmx:rmi:///jndi/rmi://<host>:<port>/jmxrmi

Of course, the server run.sh has been modified adding the proper -D parameters:

...

export JMX_PARAMS="-Dcom.sun.management.jmxremote.port=3999 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

...

java $JVM_ARGS -classpath $CLASSPATH -Dcom.sun.management.jmxremote $JMX_PARAMS org.hornetq.integration.bootstrap.HornetQBootstrapServer $FILENAME

.."

I'm using an ubuntu 10 server on Amazon EC2 cloud. Firewall has been updated with the new port required.

The problem is that I can't connect.

it takes some time until jconsole says: "connection failed", and in the meanwhile I can see a tcp connection executing a netstat on my server:

(3999 is the jmx port being used)

ubuntu@/opt/hornetq-2.2.5.Final/bin$ netstat -an | grep 3999

tcp6 0 0 :::3999 :::* LISTEN

tcp6 0 0 x.x.x.208:3999 x.x.60.1:51380 ESTABLISHED

but the connection is transient, soon it disappears.

Nothing... I cant connect via Jconsole. So, what is wrong? is there a better way to open a management console to a remote server?

I come from Tibco, Sonic, Bea and ActiveMQ background, and while considering interesting the whole HornetQ project, I really MISS a better management console....

Please help.

Regards

Michele

connecting to a remote connection is actually a FAQ on Oracle:

http://download.oracle.com/javase/1.5.0/docs/guide/management/faq.html

Regarding the administration, we have been doing some work with the Application Server 7 team. We may do something on standalone soon.

Thanks for your answer Clebert, but those FAQs didn't help.
I'm happy about future ennhancements in the standalone architecture, but now I have to fall back to other JMS providers. I'm runnig a complex architecture and I can't deal with this lack of management. pity.

have you really looked at the JMX console and Beans you have on HornetQ?

Hi Clebert,
I'm using the default bean in the standalone/non clustered configuration:

...

   <bean name="MBeanServer" class="javax.management.MBeanServer">
      <constructor factoryClass="java.lang.management.ManagementFactory"
                   factoryMethod="getPlatformMBeanServer"/>
   </bean>

...

And it should work, because if I try accessing on the same host but with the remote connection url it works. So I guess it must be a connectivity problem, even if the basic tests and firewall are fine. Definitively, it is not an HornetQ problem, but a specific limitation of JMS remote access.

If u mean other beans/configs, let me know.

a remote connection to JMX should work fine.

Anyway, a friend of ours have written some admin console that works on HornetQ. They are selling it commercially I think.

I don't mean to be doing free ad for them here, but maybe that's an option for you?

...maybe not an option for my current customer... budget is a critical issue...

But I've just downloaded the trial and will look into it.

Thanks for advice

Michele,
I have released an updated version today (1.0.2), which fixed connectivity issues with hornetq and the install will now allow installations even when it cannot find a JRE or JDK installed.

Michele,
   Something to try - not elegant but it works. Edit your hornetq-beans.xml and hardcode your servers IP address (I have used 10.0.1.11 as an example below):


   <bean name="JNDIServer" class="org.jnp.server.Main">
      <property name="namingInfo">
         <inject bean="Naming"/>
      </property>
      <property name="port">${jnp.port:1099}</property>
      <property name="bindAddress">${jnp.host:10.0.1.11}</property>
      <property name="rmiPort">${jnp.rmiPort:1098}</property>
      <property name="rmiBindAddress">${jnp.host:10.0.1.11}</property>
   </bean>
