RDF System Management Manual for H-Series RVUs (RDF 1.8)

1. Redirect the output of the RDFCOM session from your terminal to the configuration
command file by issuing an appropriate OUT command. For example, to direct subsequent
session output to the configuration command file named RDF.INIT, enter the following
command:
]OUT RDF.INIT
2. Issue an INFO * command with the OBEYFORM parameter:
]INFO *,OBEYFORM
RDFCOM lists the current parameters in the RDF configuration file to RDF.INIT in OBEY
command file format.
3. Issue another OUT command to redirect subsequent session output back to your terminal:
]OUT
For further information about configuration command files, see the example file in Appendix B
(page 329).
Configuration File Compatibility
Before running certain commands, RDFCOM compares its own version against the version of
the RDF configuration file to ensure that the configuration file is compatible with the current
version of the RDF software. If RDFCOM detects a difference, it prints the following message to
the home terminal and aborts the command:
RDFCOM version (version1) does not match the config file version (version2)
If that happens, you should make sure you are using the correct RDFCOM. If you are using the
correct version and you get this message, then you must reinitialize RDF.
If RDFCOM cannot determine the configuration file version, it prints the following message to
the home terminal and aborts the command:
RDFCOM version (version) does not match the config file version unknown
If that happens, you should make sure you are using the correct RDFCOM. If you are using the
correct version and you get this message, then you must reinitialize RDF.
Enabling RDF Operations
After you have copied all pertinent database files from the primary system to the backup system,
installed the RDF software on both systems, initialized and configured TMF on the primary and
all backup systems, and initialized and configured RDF, you can then start the TMF and RDF
subsystems. You must start TMF on the primary and all backup systems before you can start
RDF.
Starting TMF
To start or restart TMF, issue the TMFCOM command START TMF. If you plan to start the
applications being protected by TMF before starting RDF, you can include the DISABLE
BEGINTRANS parameter in the START TMF command; this parameter prevents the applications
from starting any transactions until you issue the TMFCOM command ENABLE BEGINTRANS.
For details about these TMFCOM commands, see the TMF Reference Manual.
Starting RDF
There are two ways to start RDF: with updating enabled and with updating disabled. If updating
is enabled, the updaters begin updating the backup database immediately. If updating is disabled,
they do not (but the extractor and receiver continue to work normally). The default is to start
RDF with updating enabled.
To start RDF, issue the RDFCOM command START RDF:
