[ISS Support Case] Historian Data Gap On Appengine Failover In SP Version 2023 R2 P1

Last updated: March 6th, 2025

Description

I am seeing an issue with SP2023 R2 P1 related to appengine failovers. When I cause an appengine failover, data (primarily analog) has a gap in the trend until the data changes. Sometimes the gap stays but sometimes the gap is "filled" in for some reason. I'm having a bit of a consistency issue trying to replicate this problem. Every time I cause a failover, the results are slightly different but I do see bad results. To demonstrate this, I created two videos to show what I'm seeing. If someone can create a problem ticket and reach out to me, I can forward the videos to InSource to show what I'm seeing.

[ISS Support Case] Viewapp Instances unable to see alarms

-We have a few viewapp instances that we have deployed and they are currently not able to display alarms on the system. and in the OCMC we are seeing it connect and disconnect each time we try to pull up an alarm page. --------------------------------------------------------------------------- -The System Platform we are using is 2023 R2 on an OS Windows Server 2022 Datacenter. The issue is for all alarms coming into the Viewapp instances, it was previously functioning but we had to change the historian and update all of the platforms. There arent any errors that seem applicable but the following screenshot of the alarmmgr connecting and disconnecting happens whenever we open up an alarm client. 9/10/2024: -Updated Customer on where we stand at this moment. We've escalated this issue and await Case Assignment from Tier 2 Support. 9/12/2024: -Update from customer, Fixed it by deploying an object that was higher up in the hierarchy. This was a Parent/Child relationship, and the Parent was not deployed out properly.
