Command Overview
STOP RDF
The STOP RDF command shuts down RDF.
Where Issued
Primary or backup system.
Security Restrictions
You can issue the STOP RDF command only if you are a member of the super-user
group and have remote passwords on both the primary and backup systems.
RDF State Requirement
You can issue the STOP RDF command only when RDF is running.
Usage Guidelines
The decision to stop RDF is a management decision that should be carefully planned
and performed. Operators should never issue the STOP RDF command strictly on their
own initiative.
To execute a planned RDF shutdown, you should generally use the STOP TMF
command rather than STOP RDF. Issue the STOP TMF command at the primary
system while the communications lines are up. In addition to stopping TMF, this action
stops all RDF processes and saves the context of each process in a file.
For information about when to use the STOP RDF command and how it affects the
primary and backup databases, see Restarting RDF
in section 5. For more information
about stopping RDF, continue with this discussion.
There are three ways to stop RDF:
•
Issue a STOP TMF command at the primary system.
As noted earlier, this is the recommended method for terminating RDF processing.
When you issue the TMFCOM command STOP TMF, RDF also shuts down after
RDF encounters the TMF shutdown record in the MAT. This method ensures that
the primary and backup databases are logically identical with one another when
RDF stops. When you restart RDF, the context file directs RDF where to resume.
STOP RDF
Caution. Stopping RDF without stopping TMF might make it necessary for you to
resynchronize the database.
