RDF network cannot contain two or more RDF subsystems with the same primary system (that
is, it cannot contain RDF subsystems for \A to \B and \A to \C).
BACKUPSYSTEM Attribute
The BACKUPSYSTEM attribute specifies the name of the backup system associated with the
specified primary system. There is no default value.
REMOTECONTROLSUBVOL Attribute
The REMOTECONTROLSUBVOL attribute specifies the name of the control subvolume used
by the RDF subsystem configured for the specified primary and backup systems. There is no
default value.
PNETTXVOLUME Attribute
The PNETTXVOLUME attribute specifies the name of the volume on the particular primary
system where the RDF network master stores an audited network-synchronization file. The
specified volume must be a data volume protected by the RDF subsystem on the primary system
and be configured to the MAT.
You only use this attribute when configuring the network master. On the master you must include
this parameter within every network configuration record (including the one for the master
itself).
Setting Individual Process Attributes
Having set the global attributes, you are now ready to set the parameters that apply to individual
RDF processes: the RDFNET, monitor, extractor, receiver, purger, and updater processes.
RDFNET Process
Use SET RDFNET and ADD RDFNET commands to configure the following RDFNET attributes:
• CPUS
primary-CPU
:
backup-CPU
• PRIORITY
• PROCESS
The CPUS attribute specifies the processors in the primary system in which the RDFNET process
will run.
The PRIORITY attribute specifies the priority at which the RDFNET process will run. You should
set the RDFNET process’ priority slightly lower than that of the RDF monitor process.
The PROCESS attribute supplies a name for the RDFNET process. You should specify a meaningful
mnemonic such as $RNET. The process name can be any unique valid process name up to six
characters, including the $ symbol. However, you cannot specify HP reserved process names
that are of the form $X*, $Y*, or $Z*, in which * is any alphanumeric string.
Monitor Process
Use SET MONITOR and ADD MONITOR commands to configure the following monitor
parameters:
• CPUS
primary-CPU
:
backup-CPU
• PRIORITY
• PROCESS
The CPUS attribute in the following form specifies the primary and backup processors in which
the monitor will run:
CPUS primary-CPU:backup-CPU
If the primary processor is not available when RDF is started, the monitor executes in the specified
backup processor without benefit of a backup process. When the primary processor is brought
