RDF System Management Manual for J-series and H-series RVUs (RDF 1.10)

About This Document
The Remote Database Facility (RDF) subsystem enables users at a local (primary) system to maintain
a current, online copy of their database on one or more remote (backup) systems, protecting stored
information from damage that might occur at the primary system. RDF accomplishes this by sending
audit trail information, generated at the primary system by the NonStop Transaction Management
Facility (TMF) product, over the network to the backup system. At the backup system, RDF software
uses the transported information to update the backup database so that it reflects all changes made
to the primary database. The backup database is usually current within seconds of the primary. If
system capability is lost at the primary system, service can be recovered quickly at the backup
system using the live backup database.
This manual describes the RDF subsystem as implemented in version 1, update 11 (RDF 1.10) for
RDF IMP, RDF/IMPX and Update 10 for RDF/ZLT on J-series and H-series RVUs.
This manual contains introductory and conceptual information for new users, followed by directions
for installing, configuring, and operating RDF and managing the RDF environment. It covers activities
at both the primary and backup sites and fully describes all commands available to users. It provides
complete reference information for these commands, including their syntax and semantics. Finally,
it lists all RDF messages and describes their meaning and any corrective actions that users must
take.
Supported Release Version Updates (RVUs)
This manual supports J06.03 and all subsequent J-series RVUs and H06.03 and all subsequent
H-series RVUs, until otherwise indicated by its replacement publications.
