Command Overview
SOFTWARELOC $volume.subvolume
specifies where the RDF software is installed. The default is $SYSTEM.RDF.
NETWORK {ON | OFF}
specifies whether or not you are configuring an RDF network.
When set to OFF (the default value), RDF takeover operations execute and
database consistency is not guaranteed for transactions spanning more than one
RDF backup database.
When set to ON, the RDF subsystem guarantees database consistency across
multiple RDF backup systems configured within an RDF network.
When set to ON, you must either have the NETWORKMASTER attribute for the
same system also set to ON or have another system configured as the network
master.
NETWORKMASTER {ON | OFF}
specifies whether the particular system is the master of the RDF network. Each
RDF network has one, and only one, network master.
When set to OFF (the default value), the particular system is not the network
master.
When set to ON, the particular system is the network master of the RDF network.
When this attribute is set to ON, the NETWORK attribute must also be set to ON.
UPDATEREXCEPTION {ON | OFF}
specifies the manner in which exception files are used.
When set to ON (the default value), the updaters log an exception record for each
and every audit record they must undo during a takeover.
When set to OFF, the updaters log exception records only for the first and last audit
records that must be undone (the minimum logging necessary to support Triple
Contingency operation).
LOCKSTEPVOL $volume
specifies the primary system disk volume on which the RDF lockstep file
(ZRDFLKSP.<control-subvolume>) is to be located. The specified volume must be
configured to the Master Audit Trail (MAT), and either the entire volume or at least
the lockstep file must be protected by the RDF subsystem. For information about
the RDF lockstep capability, see Section 14, Lockstep Operation.
REPLICATEPURGE {ON | OFF}
specifies whether Enscribe purge operations on the primary system are to be
replicated on the backup system.
