RDF System Management Manual for H-Series RVUs (RDF 1.8)
backup system if your primary system should fail after you stop RDF and delete the previous
RDF control files, but before you restart RDF.
By using the procedure that follows, you can install and initialize the RDF product without
stopping RDF, TMF, or your applications.
The procedure is best described by example. Assume that you are running RDF from \RDF04
to \RDF06, and that your control subvolume is RDF04.
1. For your current RDF subsystem (RDF04->RDF06), issue an RDFCOM STATUS RDF
command on the primary system.
2. Notice the general timestamp and the RTD times (11JUN2004 13:30).
Status of \RDF04 -> \RDF06 RDF 2004/06/11 13:30:42.047

3. If the extractor RTD is greater than 0:00, wait until the extractor reports this value. If the
value is 0:00, take the highest updater RTD and round up to the next minute. In this example,
the highest updater RTD rounded up to the next minute is 2:00.
4. Subtract this value from the general timestamp (11JUN2004 13:28).
5. Issue the STOP UPDATE command. This command stops the updaters but allows the
extractor and receiver to continue to shipping and storing audit, respectively.
6. Install the new RDF software in a different volume.subvolume from that housing the current
version of RDF that is running. For example, if you are upgrading to T0346AAV, you might
specify $system.rdfaav.
7. Run $system.rdfaav.RDFCOM and initialize a new RDF configuration, using
• The suffix parameter (such as suffix "a")
• The INITTIME parameter, using the timestamp calculated in the preceding example
(11JUN2004 13:28).
Initialize RDF, backupsystem \RDF06, suffix a, inittime 11JUN2004 13:28
8. If you do not already have a copy of the configuration script used for the current version of
RDF, you can get it by starting the RDFCOM for that RDF subsystem and using the INFO
*, OBEYFORM command.
9. Use the same script to configure your new RDF subsystem, but you will need to change the
following:
a. Set SOFTWARELOC to $system.rdfaav
b. Set the extractor name(s) to a different name(s)
c. Set the monitor name to a different name
d. Set the receiver name(s) to different name(s)
10. Now start your new RDF subsystem:
] run $system.rdfaav.rdfcom rdf04a
] start RDF, update off
