Redundancy switch function is not working

Redundancy switch function is not working

Summary

Redundancy switching does not work as expected for Data Hub Gateway. This has been fixed.

Description

In an integration project with at least one local project and identical server 1 and server 2, redundancy switching is triggered in both projects in parallel. All projects also use the DataHub Gateway (formerly known as Service Grid IngressConnector). The redundancy switch is never executed completely.

Cause: 

Due to the shutdown procedures of the IIoT Services Gateway (formerly known as ServiceGrid Gateway), the second project starts shutting down the IIoT Services Gateway while the first project is still busy. Both projects block each other.

The deadlock in IIoT Services Gateway of Service Engine has been fixed. Parallel redundancy switches now work when IIoT Services Gateway is active in the switched projects.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 12 or higher.
