Onsite Delivery Equipment Requirements

• NonStop server with four processors and six disk volumes G06.28, H06.15, J06.04 or later with Measure, TPDC, and RPM installed
• Private class requests:
• Might require up to two days set-up time on a customer system prior to the class
• Access to a supergroup logon for the instructor
