BellaDati is not depending on the selected cluster environment, you can run it on GlassFish, Websphere or JBoss, but there are several parameters contained in application.properties (see BellaDati WAR Configuration) which need to be changed in order to run BellaDati in the cluster):

application.actor.server.port=2335
tapestry.clustered-sessions=true
application.servers=192.168.1.10:2335,192.168.1.11:2335

The example above defines parameters for 2 servers in a cluster, running on 192.168.1.10 and 192.168.1.11.

Administrators have access to cluster overview pages, which shows useful information about the servers in the cluster.

Glassfish cluster on Linux example

AS_ADMIN_SSHPASSWORD=glassfish

1. Add cluster configuration to glassfish5/glassfish/domains/domain1/applications/belladati/WEB-INF/classes/conf/application.properties

   Code Block
   title Example for 2 servers cluster
   application.actor.server.port=2335 tapestry.clustered-sessions=true application.servers=belladati-main:2335,node1:2335

2. Have two linux servers with SSH access (user and password or certificate).
   

3. Create SSH node over console or asadmin command

   Code Block
   ./asadmin create-node-ssh --nodehost node1 --installdir /home/glassfish --install=true --sshuser glassfish --passwordfile password node1

   This command creates /home/glassfish/glassfish directory on the node server.

4. Comment out AS_JAVA in /home/glassfish/glassfish/glassfish5/glassfish/config/asenv.conf on the node server.

5. Verify SSH node by pinging the server

   Code Block
   ./asadmin ping-node-ssh node1

   Using console:

   

6. Create cluster

   Code Block
   ./asadmin create-cluster belladati-cluster

   Using console:

   

7. Create node instance and assign it to newly create a cluster

   Code Block
   ./asadmin create-instance --node node1 --cluster belladati-cluster instance-node1

8. Start instance

   Code Block
   ./asadmin start-instance instance-node1

9. Configure JDBC resources targets 

   Code Block
   ./asadmin create-resource-ref --target belladati-cluster jdbc/belladati_db

   Using console:
   

10. Configure Application targets
    
11. Start cluster

Updating BellaDati in Cluster

We recommend updating only the WAR file. It is necessary to keep the currently existing application.properties file.

Troubleshooting

• When installing Glassfish cluster on Windows, WMI and DCOM services must be enabled. Please refer to https://technet.microsoft.com/en-us/library/cc771387.aspx for enabling DCOM and to https://technet.microsoft.com/en-us/library/cc771551.aspx for enabling the WMI
• JDK has to be installed and path set to as_java must be set on both machines

BellaDatiは、選択したクラスタ環境に依存していないのでGlassFish、WebSphereまたはJBoss上でそれを実行することができますが、クラスタ内でBellaDatiを実行するために変更される必要があるapplication.properties（BellaDati WAR Configurationを参照してください）に含まれるいくつかのパラメータがあります。

tapestry.clustered-sessions=true
application.servers=192.168.1.10:2335,192.168.1.11:2335

上記の例では、192.168.1.10と192.168.1.11上で実行して、クラスタ内の2のサーバのパラメータを定義します。
