Will CA Content Viewer (Web Viewer) 14.0 run on any other platform other than USS?
No, there are no plans for that. The server has to run on the same system where the View databases are since it uses the View Agents to access the them - and currently that is only on z/OS. That's why CCI and DRAS are no longer needed with Content Viewer. This was done to improve performance. So Content Viewer will not run on z/Linux or any other platform other than USS.
