RDF System Management Manual for J-series and H-series RVUs (RDF 1.10)

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
back online, the monitor creates its own backup process in the primary processor and then switches
control to that monitor process.
The PRIORITY attribute 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 attribute 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 six 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.
