App Control: Console upgrade to 8.9 on unpatched SQL Server fails due to database script 'migrate' error

Products

• Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

• The App Control setup wizard fails with an error message:

A critical database script 'migrate' needed to install the CB App Control Server failed with an error.
Cannot continue the execution because the session is in the kill state.

• SQL memory dump created in the SQL Server logs folder

Environment

• App Control Server: 8.9
• MS SQL Server

Cause

This is caused by existing issues with unpatched SQL 2019 and prior versions when using Scalar UDF Inlining

Resolution

1. Apply the latest SQL Server Cumulative Update
2. Restore the 'Das' database from backup
3. Install the App Control 8.9 server app using the existing database option

Additional Information

 

• Per App Control Server OER guide - SQL Server 2019 Important: 

  Installation of the latest Cumulative Update is required. 
  (This is due to new feature in SQL Server 2019, inlining scalar-valued user-defined functions, which causes major issues without the latest Cumulative Update.)
