Entering RDFCOM Commands

Command Overview
When RDF starts, it automatically executes an implicit VALIDATE CONFIGURATION 
command with the following 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. 
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 in section 1 and 
Processor Failures in section 5.
Examples
To start RDF with updating enabled, enter:
]START RDF
To start RDF with updating disabled, enter:
]START RDF, UPDATE OFF
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.
