Some discrepancies in the Broadcom BSI Installation Manuals.
At first, the only available manual for multi-tier environment (One database server, one for application and one for Web Server) is the Install CA Business Service Insights on a Multi-Tier Environment. Besides the update information states "Last Updated January 25, 2021", the information on this document is outdated. The last Windows Server mentioned for App is 2016 and for Web is 2012:
Still, there is another manual where I can find an updated list with Windows Server 2019. It is the Implement CA Business Service Insight 184.108.40.206 on a Two-Tier Environment document:
The problem is that this manual is intended for a Two-Tier environment. There are still discrepancies in the Roles & Features list (according to an available list in the Windows Server 2019), and there is no distinction between roles and features that is intended only to the App server and the ones to Web Server:
Review and confirm the Roles & Features list according to a Windows Server 2019 and with clear distinction between Application Server and Web Server just like in the Multi-Tier Manual.
