only specify FASTUPDATEMODE ON if your throughput rate is typically low to moderate.
In environments with high extractor-to-receiver throughput, specifying FASTUPDATEMODE
ON will cause the extractor to fall behind TMF audit generation. See
Chapter 3 “Installing
and Configuring RDF” for a more complete discussion of this option, and note that for
FASTUPDATEMODE to achieve what you want, you must also set the RDF UPDATERDELAY
to 1 second.
The default is FASTUPDATEMODE OFF.
Where Issued
Primary system only.
Security Restrictions
None.
RDF State Requirements
None.
Usage Guidelines
The SET RECEIVER command enters the parameter values specified for the receiver 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 the subsystem 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 RECEIVER 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 a receiver process named $RCV0 to run in CPUs 0 and 1, with the RDF master
image files residing on the volume $IMAGE and having primary and secondary extents of 1000
pages each, issue these commands:
]SET RECEIVER PROCESS $RCV0
]SET RECEIVER CPUS 0:1
]SET RECEIVER RDFVOLUME $IMAGE
]SET RECEIVER EXTENTS (1000,1000)
]ADD RECEIVER
By default, in this example the receiver process is associated with the MAT and will run at a
priority of 165.
To configure an auxiliary receiver process named $RCV1 associated with the auxiliary audit trail
AUX01 to run in CPUs 2 and 3, issue these commands:
]SET RECEIVER PROCESS $RCV1
]SET RECEIVER ATINDEX 1
]SET RECEIVER CPUS 2:3
]ADD RECEIVER
