Creating a vertical Gateway cluster by adding servers to existing nodes

In an IBM® Sametime® deployment, create a vertical cluster of Sametime Gateway servers by installing additional servers onto existing nodes.

About this task

Add cluster members to an existing node to create a vertical cluster.

Procedure

  1. On the cluster's deployment manager, log in to the IBM WebSphere® Application Server's Integrated Solutions Console as the WebSphere administrator.
  2. Click Servers > Clusters > WebSphere application server clusters > SametimeGatewayCluster > Cluster members.
  3. Add a new cluster member as follows:
    1. In the list of cluster members, click the New button.
    2. Type a name for the new cluster member; for example: Node1RTCGWServer2.
    3. Select the node where you want to install this new cluster member.
      Tip: To see which servers the nodes are hosted on, use another tab to navigate to: System Administration > Nodes.
    4. Leave the remaining settings alone so that they use their default values.
    5. Click Add Member.
    6. Click Next.
    7. At the "Step 3: Summary" screen, click Finish.
  4. Click Save.
  5. Complete the following tuning procedures for each newly created server:

    This is necessary because the newly created server might be missing some tuning values used by existing servers in the cluster.

  6. If you are using XMPP connector, configure the XMPP traffic listening port for each server:
    1. Click Servers > Application Servers and select the created server from the list.
    2. Click Ports.
    3. Click New to add a port.
    4. Select User-defined Port.
    5. Type XMPP_INTERNAL_PORT in the Specify port name field.
    6. In the Host name field, type the host name of the computer on which the new gateway server is installed.
    7. In the Port field, type available port number (the port range should be 5275-5290).
    8. Click OK.
    9. Update the master configuration by clicking the Save link in the "Messages" box at the beginning of the page.
  7. Repeat steps 1 through 6 for each additional server that you want to add to an existing node.
