Creating a Configuration Command File
The PRIORITY option value specifies the priority at which the RDFNET process will
run. You should set the RDFNET process’ priority slightly lower than that of the RDF
monitor process.
The PROCESS option value supplies a name for the RDFNET process. You should
specify a meaningful mnemonic such as $RNET. The process name can be any
unique valid process name up to 5 characters, including the $ symbol. However, you
cannot specify HP reserved process names that are of the form $X*, $Y*, or $Z*, in
which * is any alphanumeric string.
Creating a Configuration Command File
You can use the INFO * command with the OBEYFORM option to create a
configuration command file quickly and easily from an existing RDF configuration:
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 option:
]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.
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 option in the START TMF command; this option prevents the
applications from starting any transactions until you issue the TMFCOM command
