Command Overview
SET RDF
The SET RDF command sets RDF global configuration parameters within the RDF
configuration memory table. The supplied values are not applied to the RDF
configuration file, however, until you issue an ADD RDF command.
LOGFILE ems-collector-name
specifies a device (EMS collector) that is to receive messages from RDF. The
specified device must exist on both the primary and backup systems. The default
is $0.
The device on the primary system receives log messages from the extractor and
monitor processes plus RDFCOM messages that are logged in message 835 and
messages from RDFNET, if configured.
The device on the backup system receives log messages from the receiver, purger,
and all updater processes (plus RDFCOM messages that are logged in message
835).
UPDATERDELAY delay
specifies how many seconds (from 1 to 10) the updater processes should delay
upon reaching the logical EOF in the image trail before attempting a new read.
The default is 10 seconds.
The default updater delay is the recommended value for virtually all users of RDF.
Lowering it could adversely affect other updaters’ performance.
You can alter the UPDATERDELAY value while updaters are running by using the
ALTER RDF UPDATERDELAY command.
