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

RDFVOLUME $volume
specifies which disk volume on the backup system is to be used for the receiver’s master
image trail (the image trail to which the receiver writes all commit/abort records). The default
is $SYSTEM.
This attribute applies only to the master receiver (the receiver process configured with an
ATINDEX value of 0). It is ignored for auxiliary receivers.
For best performance, do not use $SYSTEM as the RDFVOLUME.
If the backup system will run with updating disabled, be sure to specify an RDFVOLUME
disk that has an adequate amount of available space.
If the RDFVOLUME disk becomes filled, the receiver process will receive error 43 messages
(Unable to obtain disk space for extent) from the file system until the situation is corrected.
PRIORITY priority
identifies the execution priority for the receiver process; priority is the execution priority,
from 10 through 199. The default is 165.
PROCESS process-name
specifies the process name for the receiver process; process-name is any unique, valid
process name of up to 5 characters; the first character must be a dollar sign ($). You cannot
specify any of the reserved process names listed in the Guardian Procedure Calls Reference
Manual. Names longer than 5 characters, including the $ sign, are invalid.
This parameter is not optional. You must explicitly name the receiver process.
SLOWMODE {ON | OFF}
During normal processing, the updaters’ RTD values are typically 4 to 20 seconds behind
the extractor’s RTD value. This is expected and normal behavior, although it does not
necessarily mean that the updaters are in fact running 4 to 20 seconds behind the extractor.
The updaters cannot read past what the receiver deems safe, and that is determined by the
frequency with which the receiver updates its context records. The receiver normally updates
its context records every 5 to 15 seconds, and the updaters’ RTD values reflect that interval.
Some customers would prefer the updaters to have the lowest possible RTD value at all times.
This can be accomplished by setting SLOWMODE ON.
With SLOWMODE ON, the receiver updates its context records after processing each extractor
message buffer. This enables the updaters to read and apply image records much faster. It
also, however, slows the extractor-to-receiver throughput rate. You should only specify
SLOWMODE ON if your throughput rate is typically low to moderate. In environments with
high extractor-to-receiver throughput, specifying SLOWMODE ON will cause the extractor
to fall behind TMF audit generation.
The default is SLOWMODE OFF.

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,
