Configuring Subsequent Processing Nodes

Once the first processing node has been configured, adding new nodes to the cluster simply involves configuring the Gateway on each subsequent node.

Once the first processing node has been configured, adding new nodes to the cluster simply involves configuring the Gateway on each subsequent node.
Prerequisites:
  • The first node of the cluster is configured.
  • If applicable, the database failover connection is configured. 
To prevent collisions that could break replication, always use the hostnames for configuring database connections in a cluster. On all processing nodes, the primary database node setting should share the same value. Similarly, the secondary database nodes should also share the same value, but this should be different from the primary node setting.
Appliance Gateways
To configure subsequent appliance Gateway processing nodes:
  1. Log into the next gateway node as
    ssgconfig
    . 
  2. Select option
    2
     (Display Gateway configuration menu). 
  3. Select option
    3
     (Configure the Gateway). Note the following:
    • For
      Database Host:
       Enter the hostname for DBServer1 (the initial processing node) -- for example,
      ssg1.mycompany.com
      .
    • For
      Database Name
      : Enter the name that was used to create the database when configuring the first Gateway node.
    • For
      Database Username
       and
      Database Password
      : Enter the values used when configuring the first Gateway processing node.
    • For
      Cluster Password
      : Enter the password that was defined when configuring the first Gateway processing node. This is required to extract the settings from the database.
  4. Ensure the node is enabled and then press [
    Enter
    ] at the configuration summary.
  5. Return to the Gateway main menu and use the
    R
     option to restart the appliance. The node will join the cluster when it is started.
Repeat this procedure for each new processing node to add to the cluster.
Software Gateways
Once the first processing node has been configured, adding new nodes to the cluster simply involves configuring the Gateway on each subsequent node.
Prerequisite:
 The first node of the cluster must already be configured.
To configure subsequent software Gateway processing nodes:
  1. Be sure the Gateway package has been installed for the subsequent processing node.
  2. Start the Gateway main menu. For more information, see Gateway Main Menu (Software).
  3. Select option
    2
     (Configure the Gateway) to view the configuration options. For more information, see Configure the Gateway Application (Software).
  4. Select option
    2
     (Database Connection).
  5. Modify the database settings as appropriate. For more information, see "Gateway Already Configured" in Configure the Gateway Application (Software).
  6. Select option
    3
     (Cluster Configuration) to create a cluster passphrase. This passphrase must be the same as the one used to create the initial node.
Repeat steps 1 to 6 for each subsequent node in the new cluster.
