Configuring RDF
What about disaster points?
If the primary system fails between steps 1 and 10, you perform the takeover operation
using your previous RDF subsystem. If the primary system fails at or after step 11, you
perform the takeover operation using the new subsystem (RDF04A).
Considerations
This method does not work with long-running transactions. You must not have any
long-running transactions in the system when you start step 1, above. If you have
long-running transactions, you must stop them and wait until they clear the TMF
subsystem before you start Step 1.
If you are running with RDF process lockstep, you should change the RDF gateway
startup script to reference the new extractor name before executing Step 11. Then
stop the gateway manually. This action will restart the gateway, and the gateway will
access the new extractor.
For RDF network environments, you should subtract an additional 15 minutes from the
timestamp you calculated in Step 4.
Configuring RDF
For RDF to operate correctly, you must establish values for the following sets of
parameters in the RDF configuration file:
•
Global parameters that apply across RDF
•
Process parameters that apply to the individual monitor, extractor, receiver, purger,
updater, and RDFNET (if an RDF network master) processes, and to the image
trails
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 commands 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
options for the SET command.
Initially, some of the configuration options in the memory table are set to their default
values. You use SET commands only for those options that you want to change from
the default value.
Before issuing the ADD commands, you can verify the current option values in the
memory table by issuing SHOW commands.
