valid process name up to 5 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.
The RTDWARNING option value specifies the RTD warning threshold (in seconds,
0 or greater) for the extractor. This threshold is used by the STATUS RTDWARNING
command to determine if the extractor is to be included in its display. The display
includes the monitor process and only those RDF processes (extractor or updaters)
whose RTD exceeds their configured RTD warning threshold.
To configure an RDF extractor process named $EXT to run as a process pair in CPUs
5 and 3 of the primary system, at a priority of 185, with an RTD warning threshold of
360 seconds, issue the following commands:
]SET EXTRACTOR PROCESS $EXT
]SET EXTRACTOR CPUS 5:3
]SET EXTRACTOR PRIORITY 185
]SET EXTRACTOR RTDWARNING 360
]SET EXTRACTOR ATINDEX 0
]ADD EXTRACTOR
You can issue ADD EXTRACTOR commands only when RDF is stopped.
Receiver Process
Use SET RECEIVER and ADD RECEIVER commands to configure the following
receiver parameters:
•
ATINDEX
•
CPUS primary-CPU : backup-CPU
•
EXTENTS
•
PRIORITY
•
PROCESS
•
RDFVOLUME
•
SLOWMODE
The CPUS option value specifies the processors in the backup system in which the
receiver is to run.
The EXTENTS option value only applies to the master receiver. It specifies the size of
the primary and secondary extents for all image trail files on all image trails.
The PRIORITY option value specifies the priority at which the receiver will run. You
should set the receiver’s priority higher than that of any application’s process and
higher than that of any RDF updater process.
The PROCESS option value supplies a name for the receiver process. You should
specify a meaningful mnemonic such as $RECV. The process name can be any
