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

is mandatory. Typically program-file is $SYSTEM.SYSTEM.TACL if you want to run a
TACL macro. Alternatively, program-file could be RDFCOM if no TACL macro is required.
CAUTION: When using RDFCOM as the TRIGGER process, the control subvolume for the
reverse RDF environment must be empty before the STOP RDF, REVERSE is issued. If it is
not empty, RDF will not be able to initialize, and the reverse environment cannot be started.
infile
is the name of an edit file that will be passed as the IN file to the trigger process when it is
created. infile must be a properly-formed Guardian disk file name. The file does not have
to exist. This parameter is mandatory.
outfile
is the name of a file or process that will be passed as the OUT file to the trigger process when
it is created. outfile must be a properly-formed Guardian disk file or process name.
CPUS primary-CPU : alternate-CPU
are the numbers of the primary and alternate CPUs in which the trigger process is to run.
The alternate CPU is used only if the primary CPU is unavailable when the trigger is started.
Values range from 0 through 15. The defaults are 0:1.
priority
is the process priority of the trigger process. priority must be an integer from 10 through 199.
The default is 150.
WAIT
causes RDF to wait for the trigger process to terminate before shutting down. This is the
default value.
NOWAIT
specifies that once the trigger process is launched, RDF can immediately proceed to shut
down.
Where Issued
Primary system; backup system when the primary is not available.
Security Restrictions
None.
RDF State Requirements
None.
Usage Guidelines
The SET TRIGGER command enters the trigger parameter values specified in this command into
the RDF configuration table in memory. This table serves as an input buffer only, so these values
do not affect the subsystem until they are applied to the RDF configuration file through the ADD
command.
Example
This example shows how to configure an RDF environment to replicate from \LEFT to \RIGHT,
with the ability to reverse replication so it goes from \RIGHT to \LEFT.
The RDF configuration on \LEFT includes (the standard SET/ADD RDF, EXTRACTOR,
RECEIVER, PURGER, IMAGETRAIL and VOLUME configuration commands are omitted):
INITIALIZE RDF, BACKUPSYSTEM \RIGHT !
SET TRIGGER PROGRAM $SYSTEM.RDF.RDFCOM
SET TRIGGER INFILE $DATA01.RDFCONF.RIGHT
SET TRIGGER OUTFILE $0
SET TRIGGER WAIT
