Cluster Test - how to do it ? need test apps

[black_dev]

Hi,

I'm new in this, but I have some questions.

I have configuration like this:

Machine1:

3 ip adress.

x.x.1.0 - machine

x.x.1.1 - node1 AS7

x.x.1.2 - node2 AS7

Machine2:

2 ip adress

x.x.2.0 - machine

x.x.2.1 - vhost apache with configuration for mod_cluster.

Ok, next

Cmd to start node1:

/node1/bin/standalone.sh -server-config standalone-ha.xml -Djboss.node.name=node1

Cmd to start node2: ( other path )

/node2/bin/standalone.sh -server-config standalone-ha.xml -Djboss.node.name=node2

After start Node1 and node2 was ok.

After deploy a application with <distributable/> in web.xml cluster started.

Ok.

In mod_cluster_manager i see two nodes.

Configuration of httpd vhost:

<VirtualHost x.x.2.1:80>

        <Directory />

                Order deny,allow

                Allow from all

        </Directory>

        KeepAliveTimeout 60

        MaxKeepAliveRequests 0

       AdvertiseFrequency 5

       <Location /mod_cluster-manager>

           SetHandler mod_cluster-manager

           Order deny,allow

           Deny from all

           Allow from all

       </Location>

  ErrorLog logs/cluster-error.log

  CustomLog logs/cluster-access.log combined

  LogLevel debug

</VirtualHost>

I have some problem/questions:

1) Could you give me a application in WAR file for AS 7 + jdk7 for cluster and replication session ( fail-over )

I searched in internet but the war files not work on AS7+jdk7 or only sources ( I don;t know how to compile because I'm IT admin not developer )

2) How to set up round-robin balance or other type balance ( in my point only node1 work, node2 not work )

Pls help.

Hi Maciej,

1) Could you give me a application in WAR file for AS 7 + jdk7 for cluster and replication session ( fail-over )

I started a small project here called ClusterBench that can be used for easily benchmarking the clustering layer in AS 5 and AS 7 -- https://github.com/rhusar/clusterbench -- its basically just a distributable app exposing different access/usage patterns. It returns kind of serial version of the session, so you can easily check whether the sessions were replicated or not, or how old they are.

( I don;t know how to compile because I'm IT admin not developer )

IC, well that becomes more complicated as this is basic thing to do. If you install maven, then you should be able to build it yourself with no problem.

2) How to set up round-robin balance or other type balance ( in my point only node1 work, node2 not work )

You are probably seeing only 1 node "active" because you are not stressing the server enough. Try to add a lot of clients and see that they will actually loadbalance very well.

BTW you might want to check JMeter for stress testing your severs:

http://jmeter.apache.org/

  The Apache JMeter™ desktop application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance.  It was originally designed for testing Web Applications but has since expanded to other test functions.

Hi Radoslav,

I am pretty new to JBOSS and I am trying to get a standalone cluster up and running. I am an IT Admin, not a developer so a lot of the information about EJB and beans does not make sense to me. Could you give me an explanation or a how-to for your cluster test app?
