Preparing the RDF Environment
Before RDF can be run on an HP NonStop system, the system configurations and user
applications must meet certain RDF requirements. This section explains how to
prepare each system for RDF installation and operation, ensuring that all these
requirements are met and that you understand the RDF product’s restrictions. This
information, intended for all readers, covers the following tasks:
•
Configuring the hardware for RDF operations, including primary and backup
system configurations, disk volume considerations, and network requirements
•
Preparing the software and database files for RDF operations, including TMF and
RDF considerations, NonStop SQL/MP and Enscribe database conventions, and
application design factors
Configuring Hardware for RDF Operations
The RDF hardware requirements are summarized in Table 2-1 and described in detail
in the next few pages.
Primary System Configuration
The RDF primary system must operate under control of the HP NonStop Kernel
operating system, which is the standard operating system for HP NonStop systems.
This system must be connected over an Expand data communication path to one or
more RDF backup systems.
Backup System Configuration
The RDF backup system, like the primary system, must operate under control of the
HP NonStop Kernel operating system and be connected over an Expand path to one
or more RDF primary systems.
In the event of a disaster at the primary site, an identical copy of the primary system’s
hardware configuration ensures that the backup system can support your business
operations without lowering system performance. If the backup system’s configuration

Primary and Backup
Systems
RDF runs on HP NonStop systems under control of the HP
NonStop Kernel operating system. Each RDF primary
system must be connected through an Expand path to at
least one RDF backup system.
Communications The RDF product transmits data on any Expand data
communications lines.
