Configuring the Dispatcher service or process in WebSphere Edge Components

If you are configuring a Process Engine server farm to use WebSphere® Edge Components as a software load balancer, the Dispatcher service or process in WebSphere Edge Components must be running on the target server. The Dispatcher is used as the software load balancer.

Attention: If the WebSphere Edge Components are installed on a Windows server, add the IP address of the Process Engine farm virtual server to the list of IP addresses in the Windows network adapter's Advanced settings.

To run the Dispatcher service:

  1. Configure and administer the Dispatcher.
    1. Start the WebSphere Edge Components Load Balancer administration tool to configure the Dispatcher.
    2. Right-click on Dispatcher and select Connect to Host.
    3. Click OK.
    4. Right-click on the Host node and select Start Executor on the server that hosts the WebSphere Edge Components.
    5. Right-click on the Executor node to add a cluster.
    6. In the Cluster field, enter the load balancer virtual name.
    7. In the Cluster Address field, enter the load balancer virtual IP address.
    8. Click OK.
    9. Right-click on the cluster and add the Process Engine Main Port and the Process Engine Naming Service Port values. The default values are 32777 and 32776 respectively.
    10. Right-click on the Process Engine Main Port number entry to add the Process Engine server nodes that will part of the farm.
    11. Right-click on the Process Engine Naming Service Port number entry to add the Process Engine server nodes that will be part of the farm.
  2. Configure the Process Engine Server Virtual Host.
    1. On each of the Process Engine servers that you are configuring for load balancing, alias the loopback address to the address of the cluster. This enables the load balanced server to accept requests that were forwarded to its MAC address by the Dispatcher. Follow the steps in the Configuring the server machines section at http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.edge.doc/lb/info/ae/tcfg_configservers.html
  3. Start the connect advisors for ports 32776 and 32777.
    1. Right-click the Host node under the Dispatcher node and select Start Manager.
    2. Right-click on the Manager node and select Start Advisor to display a dialog box where you enter advisor information.
    3. From the Advisor name list box, select Connect.
    4. In the Cluster name field, enter the load balancer virtual name.
    5. In the Port Number box, enter 32776 or Process Engine Naming Service Port number.
    6. Repeat these steps to set up a connector advisor for port 32777 or Process Engine Main Port number.
  4. Validate the connect advisor connection.
    1. Select the advisor for each configured port
    2. Select the Current Statistics tab in the Dispatcher Administration tool.
    3. Check the load values of the servers. A load value of -1 indicates the server is not running or the Process Engine node is configured improperly.
