Can GT Subset run on LINUX RHEL 8? If so what else besides Java JDK is needed?
N/A
Release : 4.9.1
Component : Subset
The only TDM component that runs on Linux is the Portal with Docker.

This only to run on the Linux machine. The GT Server components (Datamaker, Fast Data Masker, GT Subset etc), are still only available in a Windows environment. For more information, see Features not available in TDM Portal in Docker.
One exception is FDM on Linux: https://techdocs.broadcom.com/us/en/ca-enterprise-software/devops/test-data-management/4-9/installing/install-test-data-manager/install-product-components/install-fast-data-masker-on-linux.html
We do not specify if you can run with Linux 8, and do not specify a docker version, so you should be fine.
