Define Alternate Nodes for Failover Support for an Outbound HTTP Connection

Edit online

About this task

If you are using standard routing to connect to an Sterling B2B Integrator server in the secure zone, you define a primary Sterling B2B Integrator server to connect to in the adapter. For each outbound node definition, you can identify up to three alternate outbound nodes to connect to when the primary Sterling B2B Integrator server is not available.

Two methods of configuring alternate Sterling B2B Integrator server routing are available.

  • Select a previously defined outbound node from the drop-down list on the Advanced tab. To configure this method, you first configure an outbound node definition in the netmap for each alternate Sterling B2B Integrator server you want to use. Each connection uses the security and other settings defined for that outbound node in the netmap.
  • Select IP address/port from the drop-down list on the Advanced tab and enter values for the IP address and port. If you use this method you do not have to define the alternate outbound nodes in the netmap, and each alternate connection shares the security and other settings defined in the primary node definition.

If you configure alternate Sterling B2B Integrator server definitions in the outbound node definition, when a connection to the primary outbound node is unsuccessful Secure Proxy tries to connect to the alternate node you defined as Node 1. If the connection to the first alternate node is unsuccessful, Secure Proxy tries to connect to the second alternate node, Node 2. If this connection is unsuccessful, Secure Proxy tries to connect to the third alternate, Node 3. If the connection to this node is unsuccessful, the inbound connection fails.

To configure alternate outbound connections:

Procedure

  1. Click Configuration from the menu bar.
  2. Expand the Netmaps tree and select an HTTP netmap to modify.
  3. Click the Outbound Nodes tab.
  4. Select the outbound node to modify and click Edit.
  5. Click the Advanced tab.
  6. To identify an alternate node defined in the netmap and use the security settings defined in the alternate node definition, select the outbound node name from the drop-down list.
  7. To configure an alternate node that is not in the netmap and use the security settings defined in the primary node definition:
    1. Select Address/Port from the drop-down list in the Alternate Destinations Node field.
    2. Provide the IP Address and Port number for the alternate outbound node.
  8. Click OK.
  9. Click Save.
