Requirements:Glassfish ESB 2.1

JDK 1.6_07

References:10.4.0.71EXXAKDA2.EXXARO.COMDASFirst Machine

10.4.0.72EXXAKPA3.EXXARO.COMNODE1Second Machine

! NOTE Images depicted in this guide are for illustration only, and do not necessarily represent theactual outcome of the instructions provided.

JDK 1.6_07 Installation1. Run the JDK setup .exe file.

Select accept if you agree with the license (declining will end the installation).


3/15

2. Select the components to be installed.

3. Select the component features to be installed.

4. Select next, and complete the installation of the JDK.


4/15

Glassfish v.2.1 Enterprise Installation1. Run the Glassfish ESB 2.1 Installation

2. Choose to accept or reject the license agreement (rejecting will end the installation)


5/15

3. Select the installation location of Netbeans as well as the JDK location (this could be found

automatically and only needs confirmation)

4. Select the installation location of Glassfish and location of the installed JDK. Keep the other

settings as default, we will delete the default domain (domain 1) later and create our own.


6/15

5. Confirm the settings and install

! Installation of the JDK and Glassfish are to be performed on all the machines that will form partof the cluster.

Domain SetupSelect which server will be the primary server (Domain Administration ServerDAS)

For the purpose of this document I will be using IP: 10.4.0.71EXXAKDA2.EXXARO.COM

1. Open the command line interface on the first machine: Start Run cmd OK.2. Navigate to the location of Glassfish\bin (ie. C:\GlassfishESBv21\Glassfish\bin)3. Enter: asadmin list-domains4. The domain 'domain1' should appear5. Enter: asadmin delete-domain domain16. Enter: asadmin create-domain --instanceport 8082 --adminport 4848 --

savemasterpassword=true --savelogin=true PROD

7. The PROD domain will be created with instance port 8080, administration port 4848 andwill save the master and admin password to the default password file.

8. You will now be prompted for the admin username, admin password and master password.Enter these to complete the domain creation.

9. Enter: asadmin start-domain PROD10.Repeat these steps on 10.4.0.72EXXAKPA3.EXXARO.COM

However, change instanceport to 8083 as DEV domain already uses 8082.


8/15

Enable and create ClusterThe domain is set up on a development profile. We need to enable cluster support to create a

Cluster. The following steps will describe how to enable and create the cluster.

1. Using your browser type the following address to open the login page for the Administrationconsole:http://10.4.0.71:4848/

2. Type in the admin username and password you entered when creating the domain. Uponlogin, either register or cancel the registration dialogue.

3. On the left select 'Application Server', the application server options and settings will appearin the left window, select 'Add Cluster Support'.

You will now be presented with a description of the changes that will be performed:

Read the notes, and then select OK.
http://10.4.0.71:4848/http://10.4.0.71:4848/http://10.4.0.71:4848/http://10.4.0.71:4848/


9/15

Once the process has been completed, you will see a 'successful' message as well as an option to

stop the domain. We will need to restart the domain anyway, so go ahead and select 'Stop Instance'.

Go back to the command line and enter asadmin list-domains

The domain should not be running.

Go ahead and enter: asadmin start-domain PROD

Once started, go into the administration console again. You will notice that 'Clusters' is now

available on the left navigation in the console.

Repeat 'add cluster support' on all machines and Glassfish domains that will participate in thecluster. For the purpose of this document the above steps are repeated on 10.4.0.72


10/15

Click on the 'Clusters' option, and then select 'New...' in the right window. Enter the name of the

cluster (for this document I have used 'Pilog-Cluster' this could be anything to describe the cluster).

Ensure the default configuration is selected as well as 'Make a copy of the selected Configuration'.

Then click 'OK'.

The Cluster will be created and appear as a sub-section of 'Clusters'

NOTE: A new cluster is only created on the machine that will function as the DAS (domain

administration server), so for the purpose of this document a new cluster is only created on

10.4.0.71 and not on 10.4.0.72


11/15

Create the Node-Agents

Second Machine (NODE1)

Open the command line interface on the second machine (10.4.0.72): Start Run cmd OK.

Navigate to the location of Glassfish\bin (ie. C:\GlassfishESBv21\Glassfish\bin)Enter: asadmin create-node-agent --hostEXXAKDA2.EXXARO.COM NODE1

This will create a node agent with the name NODE1 on 10.4.0.72 pointing to 10.4.0.71

You can check this by entering: asadmin list-node-agents

Now start the node agent: asadmin start-node-agent NODE1

First Machine (DAS)

Open the command line interface on the first machine (10.4.0.71): Start Run cmd OK.

Navigate to the location of Glassfish\bin (ie. C:\GlassfishESBv21\Glassfish\bin)

Enter: asadmin create-node-agent --hostlocalhost* DAS

This will create a node agent with the name DASon 10.4.0.71 pointing to itself.

You can check this by entering: asadmin list-node-agents

Now start the node agent: asadmin start-node-agent DAS

* You can also type: asadmin create-node-agent --hostEXXAKDA2.EXXARO.COM DAS

(The host will always be the DAS and all nodes on every machine will point to it).

Once the node agents have been created and started, you will see them under the Node Agents

section on the left window:


12/15

Creating the InstancesEnter the first machines Glassfish Administration Console: http://10.4.0.71:4848

Navigate to Clusters and select the cluster you created earlier

Click on the Instances tab located on the top right window

Select New

! Notice the two node agents in the drop down list. (DAS and NODE1)

Create the first instance which will be located on DAS by giving it the name Instance 1 and select

OK.

Repeat the steps to create another instance pointing to NODE1 with the name Instance 2 and select

OK.

Repeat the steps to create another instance pointing to DAS with the name Instance 3 and select

OK.

Repeat the steps to create another instance pointing to NODE1 with the name Instance 4 and select

OK.

You will now have four instances, twopointing to DAS and twoto NODE1


13/15

example:

Instance1 DAS

Instance2 NODE1

Instance3 DAS

Instance4 NODE1

The creation of instances is now complete.

Click on Clusters, select the cluster by ticking the box and select Stop Cluster

You will be asked to confirm, select OK

Select the cluster again by ticking the box and select Start Cluster

Confirm once again by selecting OK

The cluster will start up and automatically start the instances associated with it; the instances will

have the indicators Running with a green ticked image.


14/15

Starting the Cluster after a DAS server restartAccess the DAS server (either by remote desktop or directly)

Select Start Run cmd

Navigate to the glassfish bin directory

Enter: asadmin start-domain PRODOnce the domain is running:

Enter: asadmin start-node-agent

Log into the Administration Console and navigate to the Clusters option

Select the cluster by ticking the box and click on Start Cluster

Ensure all instances are running by selecting the Instances tab, the Status should be a green

ticked image on all instances.

Deploy a .war file and enable it to deploy within the cluster

Log into the Administration Console and navigate to ApplicationsSelect Web Applications

On the right window select Deploy

Select the file by browsing to it.

Select the Availability check box.

Ensure the Target is selected for the Cluster and not server (standalone)

Click on OK

The .war file will be deployed on the cluster and propagated to all instances.
