RDF System Management Manual for H-Series RVUs (RDF 1.8)

active volume, restore volume, or overflow volume; you merely specify the volume name.
For information about the ZLT capability, see Chapter 17 (page 309).
Where Issued
Primary system only.
Security Restrictions
None.
RDF State Requirements
None.
Usage Guidelines
The SET EXTRACTOR command enters the parameter values specified for the extractor in this
command into the RDF configuration table in memory. This table serves as an input buffer only,
and so these values do not affect RDF until they are applied to the RDF configuration file with
the ADD command.
For ATINDEX values greater than 0, the specified value must match the audit trail number of a
configured auxiliary audit trail. If you specify SET EXTRACTOR ATINDEX 2, for example, there
must be a configured auxiliary audit trail AUX02.
Furthermore, RDF objects with a particular ATINDEX value greater than 0 must together constitute
a complete set:
• If there is an extractor with an ATINDEX value of 1, there must also be a receiver with an
ATINDEX value of 1.
• If there is a receiver with an ATINDEX value of 1, there must also be a secondary image trail
with an ATINDEX of 1.
• An updater with an ATINDEX value of 1 must be protecting a primary system data volume
configured to auxiliary audit trail AUX01, and its secondary image trail must also have an
ATINDEX value of 1.
Examples
To configure an extractor process named $EXTR (associated with the MAT) to run in CPUs 3
and 4 at the default priority of 165 with an RTD warning threshold of 180 seconds, issue the
following commands:
]SET EXTRACTOR PROCESS $EXTR
]SET EXTRACTOR CPUS 3:4
]SET EXTRACTOR RTDWARNING 180
]ADD EXTRACTOR
To configure an auxiliary extractor process named $EXT1 (associated with auxiliary audit trail
AUX01) to run in CPUs 5 and 6 at the default priority of 165 with an RTD warning threshold of
180 seconds, issue the following commands:
]SET EXTRACTOR ATINDEX 1
]SET EXTRACTOR PROCESS $EXT1
]SET EXTRACTOR CPUS 5:6
]SET EXTRACTOR RTDWARNING 180
]ADD EXTRACTOR
SET IMAGETRAIL
The SET IMAGETRAIL command associates an image trail with a specific audit trail on the
primary system. The supplied value is not applied to the RDF configuration file, however, until
you issue an ADD IMAGETRAIL command.
