clustering mode in apache tomcat 5.5.25
Hello friends,
I read a lot in internet, connected to #tomcat irc channel but still no
help (except one user in irc who told me in this mailing list there are
very nice people).
So my problem is that I'm trying to use 2 tomcats in clustering mode.
I installed standard tomcat 5.5.25 downloaded from the official site.
The operating systems are RHEL4 and Open SuSE10.2
I have setenv.sh
JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:PermSize=512m
-XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError"
CATALINA_OPTS="-Dlogs.root=/extranet/logs -Dwas.install.root=/extranet"
JAVA_HOME=/jdk1.5.0_13
ENCODING=utf-8
Java version jdk1.5.0_13 (I tried with java 1.4 and the compat package
for tomcat 5.5.25 but still the same)
I changed only server.xml file on both machines. Here is how it looks like:

I changed only mcastBindAddress="127.0.0.1"
on both machines and replaced 127.0.0.1 with the appropriate IP address
of any of these machines.
everything else was the same. (Here I'm not sure if I should use the
same jvmRoute on both machines)
The problem is that in the catalina.out I have

RE: clustering mode in apache tomcat 5.5.25
Posted by Clifford Bryant <CB...@edgewater.com>.
I was clustering CAS (Central Authentication Service). I used the
<Cluster> tag from the Clustering CAS page. But, there is also a
<Cluster> tag in the server.xml that is commented out. Either one
looked like they would work with the appropriate setup. We are using
Tomcat 5.5.23, which should not be too different from Tomcat 5.5.25.
It looks like multicasting is not working on your system.

Subject: Re: clustering mode in apache tomcat 5.5.25
I used the Complex cluster configuration from this link
http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html
There is such element
mcastBindAddress="127.0.0.1"
I just changed the IP to be equal with the IP of my interface eth0 which
on the first server is 192.9.202.21 and on the second server
192.9.202.166
On both servers there are no firewalls and eth0 interfaces are set with
MULTICAST mode
Today I also did
route add -host 228.0.0.4 dev eth0
now 228.0.0.4 (which is the multicast address from the example) is
pingable.
But still this message in catalina.out

Re: clustering mode in apache tomcat 5.5.25
Posted by Niki Diulgerov <nd...@imx.fr>.
I used the Complex cluster configuration from this link
http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html
There is such element
mcastBindAddress="127.0.0.1"
I just changed the IP to be equal with the IP of my interface eth0 which
on the first server is 192.9.202.21 and on the second server 192.9.202.166
On both servers there are no firewalls and eth0 interfaces are set with
MULTICAST mode
Today I also did
route add -host 228.0.0.4 dev eth0
now 228.0.0.4 (which is the multicast address from the example) is pingable.
But still this message in catalina.out

RE: clustering mode in apache tomcat 5.5.25
Posted by Clifford Bryant <CB...@edgewater.com>.
I don't think that you need to mcastBindAddr in the <Cluster> tag. The
default <Cluster> tag doesn't have an mcastBindAddr attribute defined.
You can try setting the tcpListenAddr to the IP address of each machine.

Subject: Re: clustering mode in apache tomcat 5.5.25
Thank you very much for the help.
Indeed I figured out that
<distributable /> have to be in web.xml
I was not changing multicast address... it is 228.0.0.4
But I changed multicast bind address
on the first machine which have IP address 192.9.202.166 I set
mcastBindAddress="192.9.202.166"
and on the second with IP 192.9.202.21 I set
mcastBindAddress="192.9.202.21"
So the idea was the broadcast address to bind to the appropriate
interface (one of the machines have more than one )
Both machines and their interfaces are set with multicasting
eth0 Link encap:Ethernet HWaddr 00:03:25:2B:05:8C
inet addr:192.9.202.21 Bcast:192.9.202.255

I dont know why to add route to

Re: clustering mode in apache tomcat 5.5.25
Posted by Niki Diulgerov <nd...@imx.fr>.
Thank you very much for the help.
Indeed I figured out that
<distributable /> have to be in web.xml
I was not changing multicast address... it is 228.0.0.4
But I changed multicast bind address
on the first machine which have IP address 192.9.202.166 I set
mcastBindAddress="192.9.202.166"
and on the second with IP 192.9.202.21 I set
mcastBindAddress="192.9.202.21"
So the idea was the broadcast address to bind to the appropriate
interface (one of the machines have more than one )
Both machines and their interfaces are set with multicasting
eth0 Link encap:Ethernet HWaddr 00:03:25:2B:05:8C
inet addr:192.9.202.21 Bcast:192.9.202.255 Mask:255.255.255.0

I dont know why to add route to
239.255.0.1
as it doesnt belong to any of my networks
Please help

RE: clustering mode in apache tomcat 5.5.25
Posted by Clifford Bryant <CB...@edgewater.com>.
You should be able to just uncomment the <Cluster> tag in the Tomcat
/conf/server.xml file. Then, open the ports, and do 1-3 below, and set
up multicast. You need to enable multicast on your network. You need
to do 1-3 on both machines.
Set the multicast address back to what it was, 228.0.0.4. The multicast
address is needed for the multiple machines to communicate and share
session information.
The multicast address is a broadcast address. It is a single address.
All servers on the network will listen for it. You put the
<distributable/> tag in the web.xml of the applications that want to be
clustered.
Run these commands as root.
1. You will need to open the multicast port 45564 for UDP, and the TCP
listen port 4001 for TCP.
2. The network interfaces should be enabled for multicast.
ifconfig eth0 multicast
3. Create a multicast route for each network interface.
route add -host 239.255.0.1 dev eth0
You can check if multicast is working with,
ping 239.255.0.1
You should get multiple responses back.

Subject: clustering mode in apache tomcat 5.5.25
Hello friends,
I read a lot in internet, connected to #tomcat irc channel but still no
help (except one user in irc who told me in this mailing list there are
very nice people).
So my problem is that I'm trying to use 2 tomcats in clustering mode.
I installed standard tomcat 5.5.25 downloaded from the official site.
The operating systems are RHEL4 and Open SuSE10.2
I have setenv.sh
JAVA_OPTS="-server -Xms512m -Xmx1024m -XX:PermSize=512m
-XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError"
CATALINA_OPTS="-Dlogs.root=/extranet/logs -Dwas.install.root=/extranet"
JAVA_HOME=/jdk1.5.0_13
ENCODING=utf-8
Java version jdk1.5.0_13 (I tried with java 1.4 and the compat package
for tomcat 5.5.25 but still the same)
I changed only server.xml file on both machines. Here is how it looks
like:
<Server port="8011"
shutdown="SHUTDOWN" >
<GlobalNamingResources>
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and
saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>
<Service name="Catalina">
<Connector port="9012"
protocol="AJP/1.3" />
