Rollback Option for System Connector
We had an issue with the System Connector and had to reinstall every part of it, but then all tags in the destination system have been created again. The old tags have not been updated anymore. We think about an option to reverse every change the connector did on the destination system (delete AF Elements, Attributes, Event Frames, PI Tags) that have been created by the connector.
We thought of a workflow like this:
Delete the routing of the "not-correct-working" Connector via DCM
Delete the Connector via DCM UI (and de-registering it from DCM and Relay in that step)
Deleting the Tags, Digital Sets etc. on the Destination DA that are
connected to that "not-correct-working" Connector
Deleting the AF Elements, templates etc. (for example Event Frames) on the Destination AF that are connected to that "not-correct-working" Connector
Re-install the connector, Register it in DCM and re-establish routing
Automated rollback functionality is not planned for PI System Connector. We encourage you to consult with OSIsoft Technical Support if you encounter issues with your PI System Connector installation.
Meanwhile it would be great to get an whitepaper how to manually rollback a wrong configured connector . unfortunately it's very easy, to do a wrong configuration (e.g. include all PI Tags from PI Server, forget to set a prefix,...) or an typo occurs during configuration. It would be very bad to have "dead configurations" in the System or need to setup the whole system again.
