Upgrade compatibility considerations
The following items are known issues in this release.
-
If you are using PI Asset Framework to store complex types in AFValue and ExtendedProperties, some functionality may be lost initially on upgrade. This can be remediated by setting enableBinaryFormatter to ‘True’ in the AFSDK.config on PI Clients.
Note: Additional security protection was added that disables use of the BinaryFormatter. The 'enableBinaryFormatter' setting should be discouraged.
-
The AFElement.GetAttributeValues and AFEventFrame.GetAttributeValues methods allow an optional WindowsIdentity/ClaimsIdentity to be passed in so that a service, using a trusted subsystem model, can evaluate access for the specified user identity. However, if the service is not mapped to the Administrator Identity on the PI Asset Framework server, the identity parameters are ignored, and the attributes and data are returned with the access rights of the caller (the trusted subsystem). This may result in granting Read Data privilege to the attributes to the end-user. The work around is to run the trusted subsystem service with admin rights on the PI System. This issue only affects applications that are trying to impersonate calls to users, such as the PI SQL Data Access Server (Real-Time Query Processing Engine).
-
If you want to use PI SQL Data Access Server (RTQP Engine) with PI Server 2018 SP3 Patch 6, you must upgrade or install PI SQL Data Access Server (RTQP Engine) 2023 SP1. For more information on PI SQL Data Access Server (RTQP Engine), see PI SQL Data Access Server (RTQP Engine) 2023.
