Runtime Parameters for UDP Clustering

[janus1822]

Hi All ,

What are all the runtime parameters for UDP stack clustering ..?

[rhusar]

UDP is the default stack, you can find parameters to tune on the JGroups wiki

http://www.jgroups.org/manual-3.x/html/protlist.html#UDP

(Note that you have to use AS7 specific xml configuration.)

Hi

You check domain.xml or standalone-full-ha.xml

you will find

<subsystem xmlns="urn:jboss:domain:jgroups:1.1" default-stack="udp">

                <stack name="udp">

                    <transport type="UDP" socket-binding="jgroups-udp"/>

                    <protocol type="PING"/>

                    <protocol type="MERGE2"/>

                    <protocol type="FD_SOCK" socket-binding="jgroups-udp-fd"/>

                    <protocol type="FD"/>

                    <protocol type="VERIFY_SUSPECT"/>

                    <protocol type="BARRIER"/>

                    <protocol type="pbcast.NAKACK"/>

                    <protocol type="UNICAST2"/>

                    <protocol type="pbcast.STABLE"/>

                    <protocol type="pbcast.GMS"/>

                    <protocol type="UFC"/>

                    <protocol type="MFC"/>

                    <protocol type="FRAG2"/>

                    <protocol type="RSVP"/>

                </stack>

<stack name="tcp">

                    <transport type="TCP" socket-binding="jgroups-tcp"/>

                    <protocol type="MPING" socket-binding="jgroups-mping"/>

                    <protocol type="MERGE2"/>

                    <protocol type="FD_SOCK" socket-binding="jgroups-tcp-fd"/>

                    <protocol type="FD"/>

                    <protocol type="VERIFY_SUSPECT"/>

                    <protocol type="BARRIER"/>

                    <protocol type="pbcast.NAKACK"/>

                    <protocol type="UNICAST2"/>

                    <protocol type="pbcast.STABLE"/>

                    <protocol type="pbcast.GMS"/>

                    <protocol type="UFC"/>

                    <protocol type="MFC"/>

                    <protocol type="FRAG2"/>

                    <protocol type="RSVP"/>

                </stack>

Jboss by default use udp

A) For Udp make use of following :

<stack name="udp">

                <transport type="UDP" socket-binding="jgroups-udp"/>

             <protocol type="PING"/>

               <protocol type="MERGE3"/>

              <protocol type="FD_SOCK" socket-binding="jgroups-udp-fd"/>

               <protocol type="FD"/>

               <protocol type="VERIFY_SUSPECT"/>

              <protocol type="pbcast.NAKACK"/>

              <protocol type="UNICAST2"/>

              <protocol type="pbcast.STABLE"/>

               <protocol type="pbcast.GMS"/>

              <protocol type="UFC"/>

               <protocol type="MFC"/>

               <protocol type="FRAG2"/>

               <protocol type="RSVP"/>

           </stack>

B) For tcp make use of following :  If u want to use TCP then make default stack change to <subsystem xmlns="urn:jboss:domain:jgroups:1.1" default-stack="udp"> to <subsystem xmlns="urn:jboss:domain:jgroups:1.1" default-stack="tcp">

<stack name="tcp">

                <transport type="TCP" socket-binding="jgroups-tcp" diagnostics-socket-binding="jgroups-diagnostics"/>

                <protocol type="TCPPING">

                    <property name="initial_hosts">10.10.10.10[7600],10.10.10.10[7600]</property>

                    <property name="num_initial_members">2</property>

                    <property name="port_range">0</property>

                    <property name="timeout">2000</property>

                </protocol>

                <protocol type="MERGE2"/>

                <protocol type="FD_SOCK" socket-binding="jgroups-tcp-fd"/>

                <protocol type="FD"/>

                <protocol type="VERIFY_SUSPECT"/>

                <protocol type="BARRIER"/>

                <protocol type="pbcast.NAKACK"/>

                <protocol type="UNICAST2"/>

                <protocol type="pbcast.STABLE"/>

                <protocol type="pbcast.GMS"/>

                <protocol type="UFC"/>

                <protocol type="MFC"/>

                <protocol type="FRAG2"/>

            </stack>

Hi Senthil,

           you can specify the runtime parameter for udp clustering as

          ./standalone.sh -c standalone-ha.xml -Djboss.default.multicast.address=234.x.x.x

                                             or

             ./standalone.sh -c standalone-ha.xml -u 10.10.10.10

          -u <value>, -u=<value>            Set system property  jboss.default.multicast.address to the  given value
