RFgen High Availability

Connecting remote sites to an ERP system can be challenging when connectivity isn’t available. With RFgen’s powerful High Availability offline mobility solution, you can continue seeing, moving and consuming inventory—while disconnected from the ERP. Streamline continuity across your enterprise, regardless of connectivity state, even during ERP maintenance.

How RFgen High Availability Works

In RFgen’s default always-connected state, data collection transacts against the ERP in real-time or near-real-time. But when connectivity between a worksite and your ERP data center goes down, collected data can’t be transmitted, whether due to planned ERP maintenance or WAN/Internet outages. RFgen High Availability (“HA”) uses an HA server deployed at site-level, corporate, or both, to replicate subsets of ERP data like inventory to ensure offline data collection.

If connectivity with the ERP is lost, end-users at an entire site or organization can continue scanning and processing work without interruption until the connection becomes available again.

While offline, RFgen keeps data up-to-date by constructing a local database to queue transaction data to send to back-end systems. When connectivity is re-established, RFgen seamlessly uploads all queued transactions to the ERP in real time using a queued FIFO methodology to preserves data integrity. Local activity tables are cleared as RFgen downloads the latest ERP snapshot with the latest copy of validation data.

Use Case: Trident Foods

Seafood company needed a solution that allowed data collection at remote facilities with only periodic connectivity to their ERP. RFgen High Availability enabled the site to store data on local servers while offline transactions continued indefinitely until connectivity was re-established. Production continued without interruption, avoiding costly work delays.

Solving the Problem of Remote Inventory

If you have warehouses in remote facilities, you know that inventory control can be a major challenge. So how do you ensure accuracy or visibility? Download this free white paper to learn how RFgen High Availability solutions can help keep inventory moving, even when disconnected from the ERP.

Core Features


What do you mean by “High Availability”?

“High Availability” can be a confusing term. RFgen uses the general information technology definition of High Availability to refer to a system or component in continuous operation for extended periods. While your ERP system is offline, the RFgen HA server will operate continuously until connectivity is restored. “High Availability” does not refer to failover or redundant servers for the ERP itself in the event or disaster (“Disaster Recovery” or “DR” Server).

What data does the RFgen HA Server download from the ERP?

While connected to your ERP, the RFgen HA server can download the latest validation data from the ERP database, including quantity levels, locations, moves, consumption, and new work performed by the user. For more information, contact us to discuss your needs.

What’s the different between High Availability and Batch Mode?

RFgen High Availability solutions and RFgen Batch Mode both provide offline barcode scanning and data collection capabilities. High Availability is a server-side solution that uses a local High Availability (“HA”) server to enable continuous operations while a site is disconnected from your ERP for long windows with only periodic access to the ERP system. Batch Mode runs locally on the mobile hardware devices in a “fat client” while the device is temporarily disconnected from the network (Wi-Fi, cellular, WAN, etc.), preventing data loss or productivity interruptions for a short period.

Is RFgen High Availability a viable solution for remote countries?

RFgen High Availability servers can provide backup support for facilities or value-add sites in underdeveloped countries lacking reliable wireless infrastructure. Harvesting operations in remote parts of the world often require additional technology support when tightening inventory control. High Availability keeps the RFgen data set refreshed and up to date in these areas while also synchronizing the RFgen offline data set with the ERP when ERP connectivity returns. This is ideal for remote facilities with sporadic connectivity or very slow network connections back to the centralized ERP housed at a different location.
