Redundancy Operation

AVEVA Batch Management Development Clients and AVEVA Batch Management Runtime Clients are normally clients of a single AVEVA Batch Management Server. A redundant system has two servers, either of which can operate as the primary AVEVA Batch Management Server. Each client must therefore be connected to the primary LAN and must also be properly configured to gain network access to both servers.

The AVEVA Batch Management control system can operate concurrent configuration and run-time servers. The presence of two identical servers ensures that the backup server can continue run-time operation if the master server fails.

All database modifications are written to databases located on both the master and backup servers. If the master server fails, the backup server can continue all batch operations after the failover event.

When a failover occurs, the backup server becomes the master. When the failed Master is restored, it assumes the role of the backup server.

In a redundant configuration, the AVEVA Batch Management application files on each server are shared. When you configure redundancy for a server, all you need to provide is the network name (host name) of the other redundant server.
