Working with B2B high availability
Information about working with B2B high availability.
After configuring for B2B high availability, the B2B Gateway that owns the virtual IP address receives all traffic as the primary gateway. If the primary gateway fails, the high availability configuration ensures that the secondary gateway becomes the primary gateway, including owning the virtual IP address, and continues to process the transactions among trading partners. When the down gateway restarts, its transactional metadata is synchronized with the metadata in the current primary gateway, and this passive gateway works as the secondary gateway.
By default, a gateway restarts in a secondary mode after it fails. Therefore, if each gateway fails, no gateway works as primary until the administrator assigns one. The administrator can use the B2B transaction viewer to determine which gateway has the most recent data. To return the gateway to service, assign the gateway with the most recent data as primary and the other one as secondary.
