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

Configuring RDF
For RDF to operate correctly, you must establish values for the following sets of attributes in the
RDF configuration file:
• Global attributes that apply across RDF
• Attributes that apply to image trails
• Attributes that apply to triggers
• Network configuration record attributes
• Process attributes that apply to the individual RDFNET, monitor, extractor, receiver, purger,
and updater processes
In addition to the configuration file on disk, RDFCOM maintains a copy in memory. To configure
RDF, first use RDFCOM SET commands to establish the values you want in the configuration memory
table, and then use ADD command to apply those values to the configuration file. You do this for
each process individually; do all of the SETs for a process, and then add the particular object.
Notice that the only purpose of the configuration memory table is to serve as a temporary repository
of configuration attributes for the SET command.
Initially, some of the configuration attributes in the memory table are set to their default values.
You use SET commands only for those attributes that you want to change from the default value.
Before issuing the ADD command, you can verify the current attributes in the memory table by
issuing SHOW commands.
After issuing the ADD commands (but before starting RDF), you can change some attribute values
in the configuration file by issuing ALTER commands.
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 in “Creating a Configuration Command File” (page 89). You can then use that command
file whenever you need to reconfigure RDF. See Appendix B (page 340) for a sample configuration
file.
