Command Overview
STOP RDF
The STOP RDF command shuts down RDF.
DRAIN
causes the following actions:
•
All TMF audit records up to the time the command is entered are replicated to
the image trails on the backup node.
•
The RDF processes shut down in a manner similar to when a stop TMF record
is encountered in the audit trail.
•
Each updater shuts down after it has applied all audit records up to the stop
point.
•
The purger process reports event 852, indicating that all updaters have
stopped and the drain has completed.
REVERSE
causes RDF to replicate all audit records up to the time the command was issued,
then run the configured reverse trigger program.
You must stop all transaction activity on the primary system before issuing the
STOP RDF, REVERSE command. If there is active transaction activity on the
RDF-protected database, the database could lose integrity or data could be lost
when RDF is initialized and started in reverse. To emphasize these risks,
RDFCOM emits the following challenge in response to STOP RDF, REVERSE
commands:
**** All transaction activity in this RDF environment
**** must stopped before the STOP RDF, REVERSE command
**** is executed.
**** The REVERSE TRIGGER will be run even if the primary
**** application has not yet been stopped.
**** Are you sure you want to continue ? (yes/no)
To proceed you must type “yes” (not “y” or carriage return). “no” cancels the
command and returns you to the RDFCOM command prompt. Any other response
results in the following question:
**** Are you sure you want to continue ? (yes/no)
Again you must type either “yes” or “no”.
