Overview

Redundancy is the capability of the batch management system to automatically switch batch control to a backup server if a primary server shuts down because of a hardware failure or power loss. A secondary network should be exclusively dedicated to batch system redundancy. This secondary network supports the heartbeat between the primary and backup batch servers.

Reliable network communications between the servers is absolutely critical to the proper functioning of AVEVA Batch Management Server redundancy.

The order in which you deploy the components of the redundant system is important. You must deploy the redundant system in the following order.

1. Establish a valid network configuration.

2. Install the redundant batch servers.
