Part 1: Linux on zSeries Platform

At the DTS, VM has been used for more than twenty five years to host CMS (Conversational Monitor System) applications. These traditional VM applications include OfficeVision (PROFS), SAS, Nomad, Waterloo BASIC, Ramis, and many others. The CMS environment is considered a legacy platform, and few customers are currently developing applications for it. The following basic components are available for the VM/CMS platform as part of the standard Application Hosting service.

The DTS employs z/VM to provide the Linux on zSeries Virtual Platform.

• Basic Components
  
  • Mainframe computer hardware (shared)
  • Mainframe operating system software
  • Mainframe operating system software upgrade and maintenance (patches)
  • Mainframe operating system security administration
  • Mainframe network software
  • Mainframe connection to CSGnet
  • VM:Secure security management software
  • Many software utilities and tools
  • Software licensing and vendor contract administration
  • Data storage
