Can you provide a list of existing CA Plex license(s) for IBM i along with the command to display them?
Ca Plex all versions
A license is not needed on IBMi Server.
A CA Plex license is only needed for the Development workstations (Windows) which needs to be available in ca.olf license file. User can look for the licenses in ca.olf file in their existing development environment.
ca.olf file is in the %CA_LIC% folder. The default is C:\Program Files (x86)\CA\SharedComponents\CA_LIC
You could open a non-technical support case with Broadcom if you would need Plex license
Create a Non Technical case for Support Portal / License / Contract related issues
