Using Scripts For Easy And Fast Rdf Initialization And Configuration - HP NonStop RDF J-series RVUs Management Manual

To run RDFCOM and execute the commands in this file, supply the command file name in the
IN option of the command to start RDFCOM:
4> RDFCOM /IN RDFSET/ control-subvolume
When it uses a command file in this way, RDFCOM works in batch mode: RDFCOM begins the
session, reads and executes each command from the command file, and displays the associated
output at your terminal. When RDFCOM reaches the end of the command file or encounters an
EXIT command within that file, RDFCOM terminates the session and returns control to TACL.
If RDFCOM encounters an error while reading the command file, RDFCOM displays an error
message, terminates the session, and returns control to TACL.
If you include both the IN and OUT options in the RDFCOM command, RDFCOM reads
commands from the command file specified by the IN option and directs all output to the
destination specified by the OUT option. For example, the following command causes RDFCOM
to read commands from the command file COMFILE1 and list the output to the printer $LP:
5> RDFCOM/IN COMFILE1, OUT $LP/ control-subvolume
In addition, you can execute the contents of a command file within an interactive RDFCOM
session by using the RDFCOM OBEY command. If you regularly use a series of sequential RDF
operations in your interactive sessions, for instance, you might want to specify these in a command
file. Then each time you need these operations, you can execute them with a single OBEY
command rather than with multiple individual RDFCOM commands.
As an example, many users find that initializing RDF is much easier and more consistent when
done using command files. Suppose you have created a command file named RDFINIT that
contains the commands for initializing the subsystem. You could execute all these commands
by simply entering:
]OBEY RDFINIT
If you decide later that you want to use different installation attributes, you can change the
command file and then enter the OBEY command again. Using command files makes performing
repeated tasks very convenient.
During processing of an OBEY command, when RDFCOM reaches the end of the command file,
RDFCOM prompts you for another RDFCOM command. If RDFCOM encounters an EXIT
command within the command file, RDFCOM terminates the session and returns control to
TACL. If RDFCOM encounters an error while reading the command file, RDFCOM displays an
error message, and prompts you for another RDFCOM command.
NOTE:
Previously you could not put the RDFCOM takeover command into an RDFCOM script
file because that command prompted the user several times before it executed. By using the new
! option to the takeover command, you can now put the takeover command into a script file with
the ! option because the ! option eliminates the prompts. For more information, see the Takeover
command in Chapter 8 "Entering RDFCOM Commands" .

Using Scripts for Easy and Fast RDF Initialization and Configuration

In the discussion above, you have learned how to use RDF command scripts for RDFCOM
operations and how to use an IN file to execute a list of RDFCOM commands. Here is a highly
convenient way to use both of these methods to initialize and configure an RDF subsystem. You
create an EDIT file with the following TACL commands that you want executed on your primary
system \Boston.
fup purge $system.BOSTON.*!
fup purge \SF.$system.BOSTON.*!
rdfcom; initialize rdf,backupsystem \SF!
rdfcom /in $system.boston.rdfcfg/
rdfcom; start rdf
