3.18. Gateway Sync

The Gateway Sync menu comprises two screens, namely the Gateway Synchronization - Pending Changes screen and Gateway Synchronization - History screen. Gateway Synchronization - Pending Changes screen allows you to manually sync configurations from the portal to the Gateway. The Gateway Synchronization - History screen allows the user to choose to roll back to a backed-up instance of artifacts from a list of backed-up instances. DigitMarket™ API Manager also automatically rolls back to the previous state if during the sync process the system encounters an issue.

Gateway Synchronization - Pending Changes

All artifacts that are approved display in the Gateway Synchronization - Pending Changes screen ready to be deployed to the servers. You can select the artifacts that you want to propagate to the Gateway to make them operational at runtime.

Gateway Synchronization - History

The Gateway Synchronization - History screen displays a list of backed-up versions of data with the date and time of backup. A working instance is stored before the user manually initiates synchronization from the Gateway Synchronization - Pending Changes screen. This allows the user to roll back to an earlier backed-up version of the artifact instance.

3.18.2. View Synchronization History and Rollback

DigitMarket™ API Manager preserves backups of data for the artifacts that have been changed and for which synchronization is performed. When the user executes synchronization for an artifact, the system stores the current state of the artifact(s) in its history files before allowing the sync to happen. The rollback feature allows the user to restore the gateway to its earlier state from the history. The user can roll back to the earlier version of the artifacts through the Gateway Synchronization - History screen. Rollback allows the user to restore data to its previous state before the propagated data is made operational on all available Gateways. The rollback history displays the synchronization date along with the rollback point details.

Note

To achieve the rollback for a particular propagation, all the relevant Gateways should be up and running.

To roll back to an earlier version:

1. In the main Navigation menu, click Gateway Sync and then in the submenu that appears, click History. The Gateway Synchronization - History page displays.

   

   Fig. 3.410 Gateway Sync History

   On the Gateway Synchronization - History page, on the left side of the page, you can see the synchronization date history of the most recent propagations. The date, time and details of propagation is displayed for each propagation history. The artifacts that have been propagated are displayed in a card format. The card displays details about the artifact.

2. Click on each Synchronization Date collapsible tab to view the number of propagations occured on that particular date. If many propagations have occurred on the same day, the propagations will be listed in chronological order according to the time of propagation. The most recent propagation will be displayed at the top. The Pagination feature at the bottom-right corner of the Gateway Synchronization History page displays the number of propagation history to per page. Use the previous and next icons to navigate between the pages.

   

   Fig. 3.411 Gateway Sync History

3. To roll back to an earlier version, click the Rollback Here button.

   

   Fig. 3.412 Rollback Here

4. The Gateway Sync dialog opens. Click Rollback to start the rollback process.

   

   Fig. 3.413 Rollback

5. In the Gateway Sync dialog box, click Finish to complete the rollback.

   

   Fig. 3.414 Finish

Rollback reverts the last propagation of artifacts changes and will be available in the Gateway Sync - Changes page.

Note

• You can only rollback the propagation one by one.
• Plan level details (i.e. plan_name, pricing_type, signup_fee, termly_fee, termination_fee, currency, term_validity, auto_renew and other pricing details) willl not be rolled back.
