Adding ports to the virtual host alias for the SIP Edge Proxy cluster

After creating a SIP Edge Proxy cluster, you must add the SIP ports of each cluster member to the virtual host alias. This step is required to ensure that the cluster operates properly.

About this task

Update the default_host virtual host with a unique set of web access ports. Such a configuration lets a single host machine resemble multiple host machines.

Tip: Print this page and use the table to record the port settings as you look them up in steps 1 and 2.

Procedure

  1. Determine the ports used by every cluster member:
    1. Log in to the WebSphere® Integrated Solutions Console as the WebSphere administrator.
    2. Click Servers > Server Types > WebSphere application servers.
    3. In the table that lists the servers, click the name of the cluster member to display the cluster member's "Configuration" page.
    4. On the "Configuration" page, in the Communication section, expand Ports.
    5. Look in the Ports table and write down the following port settings for use in the next step:
      • SIP_DEFAULTHOST
      • SIP_DEFAULTHOST_SECURE
    6. Repeat this process for every cluster member.
  2. Next, determine the ports used by every WebSphere proxy server that operates with this cluster.
    1. Again in the WebSphere Integrated Solutions Console navigation pane, click Servers > Server Types > WebSphere proxy servers.
    2. In the table that lists the servers, click the name of the WebSphere proxy server.

      This displays the cluster member's "Configuration" page.

    3. On the "Configuration" page, in the Communication section, expand Ports.
    4. Look in the Ports table and write down the following port settings for use in the next step:
      • PROXY_SIP_ADDRESS
      • PROXY_SIPS_ADDRESS
    5. Repeat this process for every WebSphere proxy server used by the cluster.
  3. Add the ports used by all the cluster members and all of the WebSphere proxy servers to the Virtual Hosts table.
    1. Return to the WebSphere Integrated Solutions Console navigation pane and click Environment > Virtual Hosts.
    2. In the Virtual Hosts table, click the host called default_host.

      This displays the "Configuration" page for the default_host.

    3. In the Additional Properties section, click Host Aliases.
    4. In the "Host Aliases" table, add the ports used by all of the cluster members (the information you collected in Steps 1 and 2).

      Remember that you have information on the two ports for each cluster member; however if a port is already listed in the table, you do not need to add it again. To add a port:

      1. Click the New button at the beginning of the table.
      2. In the Host Name field, type *.
      3. In the Port field, type a port from your list.
      4. Click OK.
      5. Repeat this for the two ports for every cluster member (unless a port is already listed in this table).
    5. Delete all of the table entries that do not use * as the Host Name. For each entry you want to delete, click the check box, and then click the Delete button at the beginning of the table.
    6. When prompted to save the changes, first synchronize the nodes, and then save the new port settings to the master configuration and in the cluster:
      1. Click Preference > Synchronize nodes.
      2. Click the Save button.
