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

Extractor Process
Use SET EXTRACTOR and ADD EXTRACTOR commands to configure the following extractor
parameters:
• ATINDEX
• CPUS primary-CPU : backup-CPU
• PRIORITY
• PROCESS
• RTDWARNING
• VOLUME
The ATINDEX attribute specifies an integer value from 0 through 15 specifying the TMF audit trail
on the primary system with which the extractor is associated. 0 specifies the MAT. 1 through 15
specify auxiliary audit trails AUX01 through AUX15. The default is 0. If you omit this attribute,
RDFCOM assumes the extractor is associated with the MAT. For information about protecting
auxiliary audit trails, see Chapter 13 (page 276).
The CPUS attribute specifies the processors in the primary system in which the extractor will run.
The PRIORITY attribute 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 attribute supplies a name for the extractor process. You should specify a meaningful
mnemonic such as $EXT. 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.
The RTDWARNING attribute 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.
The VOLUME attribute specifies a valid volume name in the current TMF configuration on your
primary system. When configuring RDF for ZLT, you must add the complete set of audit trail volumes
to which protected data volumes are configured. You use a SET EXTRACTOR VOLUME statement
for each individual volume. You do not need to specify whether the volume is an active volume,
restore volume, or overflow volume; you merely specify the volume name. For information about
the ZLT capability, see Chapter 17 (page 320).
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 ATINDEX 0
]SET EXTRACTOR PROCESS $EXT
]SET EXTRACTOR CPUS 5:3
]SET EXTRACTOR PRIORITY 185
]SET EXTRACTOR RTDWARNING 60
]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 attributes:
• ATINDEX
• CPUS primary-CPU : backup-CPU
• PRIORITY
• PROCESS
