Entering RDFCOM Commands
Compaq NonStop™ RDF/IMP and IMPX System Management Manual—522204-001

Command Overview
Where Issued
Primary system only.
Security Restrictions
You can issue the INITIALIZE RDF command only 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 the
configuration file does not 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 the configuration file from the control subvolume on both the
primary and backup systems.
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 can only alter that character by issuing
another INITIALIZE RDF command.
When using the INITIALIZE RDF command, follow these guidelines:
•
If you include the TIMESTAMP option in the INITIALIZE RDF command, then the
specified timestamp must correspond exactly to a TMF shutdown point.
Whenever TMF stops in response to a STOP TMF command, it writes a timestamp
in the Event Management Service (EMS) log. That is the timestamp you use with
the TIMESTAMP option of the INITIALIZE RDF command.
•
If you do not include the TIMESTAMP, INITTIME, or SYNCHDBTIME options in
the INITIALIZE RDF command, you must delete and reconfigure TMF before you
