Configuring RDF
Setting Individual Process Parameters
Having set the global parameters, you are now ready to set the parameters that apply
to individual RDF processes: the monitor, extractor, receiver, purger, and updater
processes.
Monitor Process
Use SET MONITOR and ADD MONITOR commands to configure the following
monitor parameters:
•
CPUS primary-CPU : backup-CPU
•
PRIORITY
•
PROCESS
The CPUS option value 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 back online, the monitor creates its own backup process in the
primary processor and then switches control to that monitor process.
The PRIORITY option value specifies the priority at which the monitor will run. You
should set the monitor’s priority higher than that of any application’s process.
The PROCESS option value supplies a name for the monitor process. You should
specify a meaningful mnemonic such as $AMON or $MON1. The process name can
be any unique valid process name up to 5 characters, including the $ symbol.
However, you cannot specify NonStop SQL/MP reserved process names that are of
the form $X*, $Y*, or $Z*, in which * is any alphanumeric string.
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.
