Running multiple instances of JBoss 6.0.0M4 on the same machine

[longbeach]

Hi,

I am using JBoss 6.0.0 M4

I am trying to test load balancing with JBoss and for that i need to run multiple instances of JBoss on the same machine.

Here is how server 1 is configured (I have only changed the default jboss.web.http.port to 8084):

D:\jboss-6.0.0.20100721-M4-Server1\server\default\deploy\jbossweb.sar\server.xml :

<!-- A HTTP/1.1 Connector on port 8080 -->
      <Connector protocol="HTTP/1.1" port="8084" address="${jboss.bind.address}"
               connectionTimeout="20000" redirectPort="${jboss.web.https.port}" />

      <!-- Add this option to the connector to avoid problems with
          .NET clients that don't implement HTTP/1.1 correctly
         restrictedUserAgents="^.*MS Web Services Client Protocol 1.1.4322.*$"
      -->

      <!-- A AJP 1.3 Connector on port 8009 -->
      <Connector protocol="AJP/1.3" port="${jboss.web.ajp.port}" address="${jboss.bind.address}"
         redirectPort="${jboss.web.https.port}" />

Here is how server 2 is configured :

D:\jboss-6.0.0.20100721-M4-Server2\server\default\deploy\jbossweb.sar\server.xml :

<!-- A HTTP/1.1 Connector on port 8080 -->
      <Connector protocol="HTTP/1.1" port="8085" address="80852"
               connectionTimeout="20000" redirectPort="80850" />

      <!-- Add this option to the connector to avoid problems with
          .NET clients that don't implement HTTP/1.1 correctly
         restrictedUserAgents="^.*MS Web Services Client Protocol 1.1.4322.*$"
      -->

      <!-- A AJP 1.3 Connector on port 8009 -->
      <Connector protocol="AJP/1.3" port="80851" address="80852"
         redirectPort="80850" />

Server1 stars fine. Then I also start server2 and i get a java.net.BindException : Address already in use : JVM_Bind

I assume i still need to change some ports in server2. Which files do i need to change ?

Ports configuration has changed since JBoss 4.2, even JBoss 5.1

Any help would be great.

Thanks in advance.

Don't change the server.xml. Instead use the ServiceBindingManager to start multiple instances of the server on the same machine. See this for details http://community.jboss.org/wiki/AS5ServiceBindingManager

thanks jaikiran pai.

I modified all the ports in the D:\jboss-6.0.0.20100721-M4-Server1\server\default\conf\bindingservice.beans\META-INF\bindings-jboss-beans.xml file.

Only this server, I left all default ports on the second server.

It works.

I did not read everything on that link you pointed me to, it's a bit long and i'm a bit in a hurry, i hope that i did not miss anything important.

Basically it seems ports configuration no longer occurs in server.xml file but in bindings-jboss-beans.xml file.

Someone correct me if i am wrong.

Thanks.

I should add one thing :

the topic of my problem is not correct.

Indeed I am not using 2 instances of a single server but 2 instances that come from 2 servers.

One instance, one server.

I know one can run multiple instances of a single server, so i believe that precision is important.
