Creating the Bandwidth Manager cluster

Create the cluster configuration for an IBM® Sametime® Bandwidth Manager cluster. The two application servers that were just installed need to be clustered together before installing the Sametime Bandwidth Manager software. Ensure that the Deployment Manager is running as well as the node agent on each application server. Services are not created for the node agents, so they are started manually. We will also create services for them in a later step.

About this task

Create the cluster on the computer hosting the deployment manager.

Procedure

1. Start the deployment manager:
   1. On the server hosting the deployment manager, open a command window.
   2. Navigate to the \bin folder of the deployment manager profile and run the startManager command:
      • Linux™:

        cd /opt/IBM/WebSphere/AppServer/profiles/DM_profile_name/bin
        startManager.sh

      • Microsoft™ Windows™:

        cd C:\Program Files\WebSphere\AppServer\profiles\DM_profile_name\bin
        startManager.bat

2. Start each application server's node agent:
   1. Navigate to the \bin folder of the application server node's profile and run the startNode command:
      • Linux:

        cd /opt/IBM/WebSphere/AppServer/profiles/Node_profile_name/bin
        startNode.sh

      • Windows:

        cd C:\Program Files\WebSphere\AppServer\profiles\Node_profile_name\bin
        startNode.bat

   2. If you have two nodes, repeat this step for the second node.
3. Log in to the Integrated Solutions Console as the WebSphere® administrator.
4. On the navigation tree, click Servers > Clusters > WebSphere application server clusters.
5. On the clusters page, click the New button at the beginning of the table.
6. On the Create a new cluster page, type a descriptive name for the cluster (for example, BWMcluster).
7. Click Configure HTTP session memory-to-memory replication. Click Next.
8. On the Create first cluster member page, type a descriptive name for the first cluster member (for example, BWMserver1). In the Select node field, select the first Bandwidth Manager server node. Click Next.
9. On the Create additional cluster members page, add a second cluster member by completing these steps:
   1. In the Member name field, enter a cluster member name, for example, BWMserver2.
   2. In the Select node field, ensure that the second Bandwidth Manager server is selected.
   3. Click Add Member.
10. Ensure that you see both cluster members in the Member name and the Node fields in the table, and then click Next.
11. Review the summary information to ensure that each server name coordinates to a unique node name. Click Finish.
12. Click the Save link in the "Messages" box at the beginning of the page.
13. Synchronize all nodes in the cluster by completing these steps:
    1. From the Integrated Solutions Console, click System administration > Nodes.
    2. Select all of the nodes in the cluster.
    3. Click Full Resynchronize.
14. Restart the node agents from the Integrated Solutions Console by completing these steps:
    1. Click System Administration > Node Agents.
    2. Select each node agent in the table. and then click Restart.
    3. Click the Status icon to refresh. When the node agents are green, proceed to the next step.
    4. Servers > Clusters > WebSphere application server clusters >
    5. Select the cluster and click Start to start all cluster member servers.
    6. In the Status column, ensure that the arrow is green.
