Configuring RDF
If you omit the PROCESS option, the operating system selects a name for the monitor
process.
To configure an RDF monitor process named $MON1 to execute as a process pair in
CPUs 4 and 6 of the primary system at a priority of 186, issue the following commands:
]SET MONITOR PROCESS $MON1
]SET MONITOR CPUS 4:6
]SET MONITOR PRIORITY 186
]ADD MONITOR
You can issue ADD MONITOR commands only when RDF is stopped.
Extractor Process
Use SET EXTRACTOR and ADD EXTRACTOR commands to configure the
following extractor parameters:
•
CPUS primary-CPU : backup-CPU
•
PRIORITY
•
PROCESS
•
RTDWARNING
The CPUS option value specifies the processors in the primary system in which the
extractor will run.
The PRIORITY option value specifies the priority at which the extractor will run. You
should set the extractor’s priority slightly lower than that of the RDF monitor process.
The PROCESS option value, if present, supplies a name for the extractor process. If you
choose to name the extractor, you should specify a meaningful mnemonic such as $EXT.
The process name can be any unique valid process name up to 5 characters, including
the $ symbol. However, you cannot specify Compaq reserved process names that are of
the form $Xddd, $Yddd, or $Zaaa, in which d is any numeric character and a is any
alphanumeric character. If you omit the PROCESS option, the operating system selects a
name for the extractor process.
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.
