Preparing the RDF Environment
Before RDF can be run on your Compaq NonStop™ Series 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, 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 Compaq NonStop™ Kernel
operating system, which is the standard operating system for Himalaya 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
Compaq 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
is identical to that of the primary system, your system personnel can adjust more quickly
to the backup environment during disaster recovery.
Table 2-1. RDF Hardware Requirements
Hardware Requirements
Primary and Backup Systems RDF runs on Himalaya systems under control of the
Compaq 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.
