Usage Guidelines
If you omit
system
,
volume
, or
subvolume
, RDFCOM uses the defaults in effect when RDFCOM
was started.
A command file can contain other OBEY commands, nested up to four levels deep.
RDFCOM reads the commands in the command file until it reaches an EXIT command or the
end of the file:
• If it encounters an EXIT command, RDFCOM closes the command file, terminates the
RDFCOM session, and passes control back to the TACL command interpreter.
• If it encounters the end of the file, RDFCOM closes the command file and reads its next
command from the file from which it read the OBEY command.
RDFCOM returns an error message if the command file cannot be opened or does not exist, or
if any command within the command file is syntactically incorrect or otherwise in error. After
this message appears, RDFCOM closes the command file and reads its next command from the
file from which it read the OBEY command.
Example
The following OBEY command reads and processes RDFCOM commands from the command
file named RDFCONX:
]OBEY RDFCONX
OPEN
The OPEN command identifies the RDF control subvolume to which subsequent RDFCOM
commands in this session apply.
On the primary and backup systems, the RDF configuration and context files are stored in the
RDF control subvolume on $SYSTEM. On the backup system, the image trail files for each trail
are stored in the RDF control subvolume on the associated image trail volume.
OPEN control-subvol
control-subvol
is the name of the RDF control subvolume on both primary and backup systems.
The control subvolume name is comprised of the primary system name of the RDF
configuration (without the backslash) plus the optional character suffix if you included one
in the INITIALIZE RDF command.
Where Issued
Primary or backup system.
Security Restrictions
None; anyone can enter the OPEN command.
RDF State Requirement
Before you can enter the OPEN command, RDF must have been initialized.
Usage Guidelines
Issue an OPEN command to select the RDF control subvolume to which any subsequent RDFCOM
commands (except another OPEN command) will apply.
Using the OPEN command is the same as specifying a control subvolume in the RDFCOM
command that begins a session. For example, the following two command sequences both
