RDF System Management Manual for H-Series RVUs (RDF 1.8)

If you have initialized the TMF and RDF subsystems before issuing the START RDF command,
RDF automatically begins transmitting audit data from the beginning of the first audit-trail file.
CAUTION: If you initialize RDF after a STOP RDF command is issued at the primary system,
you might need to resynchronize the databases before restarting RDF.
Transaction processing need not be enabled on the primary system, however, when you enter
the START RDF command; it is enough that TMF has been started before you issue this command.
When RDF starts, it automatically executes an implicit VALIDATE CONFIGURATION command
with these results:
• If any parameter value in the RDF configuration file is incorrect, RDFCOM displays an error
message, and the START RDF operation fails.
• If all of the parameters in the RDF configuration file are correct, RDF copies the configuration
file from the primary system to the backup system, displays any warning messages, and
starts the RDF processes.
After all RDF processes start, RDFCOM prompts you for your next command.
NOTE: RDF always starts with updating enabled unless you explicitly specify UPDATE OFF.
This scenario is true even if updating was disabled when RDF was last stopped.
The extractor, receiver, purger, RDFNET, and updater processes are restartable. Thus, if any of
these process pairs terminates unexpectedly, you can restart the pair simply by issuing a START
RDF command. You need not resynchronize your database nor reinitialize RDF before issuing
this command. For more information about how these processes support restartability, see “RDF
Operations” (page 47) and “Processor Failures” (page 125).
Examples
To start RDF with updating enabled, enter:
]START RDF
To start RDF with updating disabled, enter:
]START RDF, UPDATE OFF
START UPDATE
The START UPDATE command starts all updater processes on the backup system.
START UPDATE
Where Issued
Primary system only.
Security Restrictions
You can issue the START UPDATE command if you are a member of the super-user group and
have a remote password from the RDF primary system to the backup.
RDF State Requirement
Before you can issue this command, RDF must be running.
Usage Guidelines
After the updater processes start, they examine the audit data in the RDF image files and apply
any changes to the backup database.
