Using RDFCOM Noninteractively

•

If you press BREAK when an RDFCOM command that changes the RDF

configuration or status (such as ALTER RDF) is in progress, RDFCOM continues to

execute this command while immediately prompting you for another one.

Using RDFCOM Noninteractively

When you use RDFCOM noninteractively, you enter one or more commands to

RDFCOM at the same time you start your session. RDFCOM executes all of these

commands, and then terminates the session and returns control of your terminal to

TACL.

To run RDFCOM noninteractively, you enter the RDFCOM keyword, the control

subvolume name, and one or more RDFCOM commands on the same line. The

following example includes a command that displays current configuration information

for the RDF monitor (the example assumes that \LONDON is the primary system, the

suffix character “A” was specified in the INITIALIZE RDF command, and the user did

not explicitly name the monitor process):

1> RDFCOM LONDONA; INFO MONITOR

RDFCOM - T3046A01 - 13JAN2000

MONITOR CPUS 0:1

MONITOR PRIORITY 170

As this example illustrates, after the command is executed, the RDFCOM session

automatically terminates and the TACL prompt again appears.

To specify multiple RDFCOM commands on a single line, you must enter a semicolon

(;) to separate each command from the preceding one. For example:

3> RDFCOM LONDONA; INFO MONITOR; INFO EXTRACTOR

If any command on the line fails, RDFCOM reports the error and terminates without

executing any of the subsequent commands.

Using RDFCOM From a Command File

RDFCOM can also read commands from a command file. The command file is a text

file that contains the RDFCOM commands you want to execute, which you prepare

using your standard text editor. You might, for example, create a command file named

RDFSET that contains the following commands:

SET RDF PRIMARYSWAP $SWAP

SET RDF BACKUPSWAP $SWAP

ADD RDF

Note. On your terminal, the BREAK key might not actually be labeled “BREAK.” All terminals,

however, have some key or combination of keys that perform the BREAK operation. Before

using RDFCOM, determine how this operation is selected on your terminal.
