Assume that you run the IBM DB2 Analytics Accelerator for IBM z/OS (IDAA) to get complex analytic information from your DB2-for-z/OS environment. When you run a Select Count (*) statement by using the Microsoft Managed Provider for DB2, which is installed along with Host Integration Server 2016, you receive incorrect results.
This issue occurs because IBM DB2 Analytics Accelerator for IBM z/OS (IDAA) requires support for the following DRDA (Distributed Relational Databased Access) Codepoints in the OPENQRY (OpenQuery) DRDA Protocol Flow:
These Codepoints were not implemented in the "release" version of Host Integration Server 2016.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
