About This Manual
The Remote Database Facility (RDF) subsystem enables HP NonStop™ Series 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 HP 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 Remote Database Facility (RDF) subsystem as
implemented in the HP NonStop RDF/IMPX and ZLT independent products for
HP Integrity NonStop servers. It 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.
