RDF System Management Manual for H-Series RVUs (RDF 1.8)

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 Parameter
The UPDATEREXCEPTION parameter 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 Parameter
The LOCKSTEPVOL parameter specifies the primary system disk volume on which the RDF
lockstep file (control-subvolume.ZRDFLKSP) 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 Chapter 15 (page 289).
REPLICATEPURGE Parameter
The REPLICATEPURGE parameter specifies whether Enscribe purge operations on the primary
system are to be replicated on the backup system.
When set to OFF (the default value), Enscribe purge operations are not replicated. You should
use the default (OFF) for all RDF configurations (unless you have a specific need for replicating
Enscribe purge operations).
If you configure the RDF subsystem to replicate network transactions, you should not replicate
Enscribe purge operations because doing so might result in unexpected errors during the updater
network undo processing.
When set to ON, Enscribe purge operations on the primary system are replicated on the backup
system.
REMOTE MIRROR Parameter
The REMOTE MIRROR parameter specifies whether ZLT is enabled or disabled. The default is
off. For information about the ZLT capability, see Chapter 17 (page 309).
REMOTE STANDBY Parameter
The REMOTE STANDBY parameter specifies the system name of the ZLT standby system.
node-name must be a valid name and must identify a system in your current Expand network.
The default is the name of the backup system. For information about the ZLT capability, see
Chapter 17 (page 309).
OWNER Parameter
The OWNER parameter specifies a userid under which all RDF processes will always run. This
global configuration parameter provides functionality whereby any super-user group userid can
start and stop RDF.
To illustrate this functionality, imagine ten users are responsible for managing a particular RDF
configuration and that SUPER.RDF is configured as the OWNER. Instead of providing all ten
users access to the SUPER.RDF userid, each individual user can be assigned a separate super-user
group userid. If one user is assigned SUPER.FIRST and another SUPER.SECOND, for example,
they can both log on with their userid and be able to start or stop RDF. The RDF processes do
not run under SUPER.FIRST or SUPER.SECOND, however, but under SUPER.RDF (the RDF
OWNER assigned during configuration). The same principal applies to the other eight users.
