RDF System Management Manual for H-Series and J-Series RVUs (RDF 1.9)

#
causes the control subvolume files both on the primary and backup systems to be purged
before initialization.
• If used in an interactive mode (either as a command from RDFCOM or in an OBEY file
) without "!" operator, RDFCOM displays:
RDFCOM will purge all the files in the control subvolume
(of both local & remote systems) if present.
Do you wish to proceed? [Y/N]
Processing continues based on User Reply.
• This operator cannot be used inside an IN file without "!".
Where Issued
Primary system only.
Security Restrictions
You can issue the INITIALIZE RDF command if you are a member of the super-user group.
RDF State Requirement
You can issue the INITIALIZE RDF command only when RDF is stopped and no files exist in
the RDF control subvolumes on either the primary and backup systems.
Usage Guidelines
If your RDF subsystem is running and you do not include the TIMESTAMP, INITTIME, or
SYNCHDBTIME options in the INITIALIZE RDF command, then you must stop, delete, and
reconfigure TMF before entering the INITIALIZE RDF command.
Before issuing the INITIALIZE RDF command within an existing RDF configuration, you must
first purge all files from the control subvolume on both the primary and backup systems or you
must use the # option that authorizes RDFCOM to purge all of the files.
TMF must be started on the primary system, but transaction processing need not be enabled,
when you enter the INITIALIZE RDF command either with or without the TIMESTAMP,
INITTIME, or SYNCHDBTIME options.
The INITIALIZE RDF command creates the configuration and context files for establishment of
a new RDF configuration. After issuing the INITIALIZE RDF command, you must build the new
configuration by entering the appropriate SET and ADD commands or by executing a command
file containing those commands. Only then can you issue the START RDF command to start
RDF.
The INITIALIZE RDF command also establishes the name of the RDF control subvolume, which
you subsequently specify when initiating RDFCOM sessions or in OPEN commands.
If you include the SUFFIX parameter, the specified character becomes a permanent part of the
RDF control subvolume name and you cannot alter it. If you want to change it, you must
reinitialize RDF again and specify a new suffix character. Note, however, that if you reinitialize
RDF with a new suffix character, you should remember to purge the control subvolume and
image trails of the previous configuration you are replacing.
When using the INITIALIZE RDF command, follow these guidelines:
• The INITTIME option is particularly useful for initializing RDF without having to STOP
TMF. For example, if you have been running RDF 1.8, you have stopped RDF, and you have
just installed the RDF 1.9 software, use the INITTIME option instead of having to stop TMF.
See Chapter 3 (page 69) for a discussion on this type of operation.
• The SYNCHDBTIME is the option you would use when performing an online database
synchronization operation. For a full discussion on this option used in conjunction with a
complete or partial database synchronization, see Chapter 7 (page 167).
