Examples
To display current RDF configuration information and operational statistics once, enter this
command:
]STATUS RDF
To display that information 10 times, once every minute, enter:
]STATUS RDF, PERIOD 60, COUNT 10
To display current information and statistics for all configured extractor processes once, enter
this command:
]STATUS EXTRACTOR
To display current information and statistics for only those processes (the extractors or any
updater) that have fallen behind the configured RTD threshold (
rtd-time
), enter this command:
]STATUS RTDWARNING
STOP RDF
The STOP RDF command shuts down RDF.
STOP RDF { [, DRAIN ] }
{ [, REVERSE ] }
DRAIN
causes the following actions:
•
All TMF audit records up to the time the command is entered are stored in 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 displays this 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 this question:
**** Are you sure you want to continue ? (yes/no)
Again you must type either “yes” or “no”.
Where Issued
You can issue the STOP RDF, DRAIN and STOP RDF, REVERSE commands only at the primary
system.
