Configuring RDF
After issuing the ADD commands (but before starting RDF), you can change some
parameter values in the configuration file by issuing ALTER commands.
Setting Global Parameters
The SET RDF command establishes values for global parameters that apply either to the
entire RDF system or to all updater processes. These parameters and their default values
are:
SWAP Parameters
The PRIMARYSWAP and BACKUPSWAP parameters specify the data stack swap
volumes for RDF processes on the primary and backup systems, respectively.
For example, if you want to configure $SYSTEM as the backup swap volume and
$GOLD as the primary swap volume, issue the following commands:
]SET RDF PRIMARYSWAP $GOLD
]ADD RDF
Note. Instead of issuing SET and ADD commands interactively within an RDFCOM session,
you can create and execute an RDF configuration command file. The first time you configure
RDF, you can either configure it interactively or use the text editor to create a command file.
After you have configured RDF, you can easily create a command file from the existing
configuration file as explained under Creating a Configuration Command File
later in this
section. You can then use that command file whenever you need to reconfigure RDF. Refer to
Appendix B, Additional Reference Information for a sample configuration file.

PRIMARYSWAP The volume specified by the PRIMARYSWAP parameter applies
to all RDF processes running on the primary system (the monitor
and the extractor).
BACKUPSWAP The volume specified by the BACKUPSWAP parameter applies
to all RDF processes running on the backup system (the receiver,
purger, and all updaters).
