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

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
By default, in this example the auxiliary receiver process will run at a priority of 165.
SET TRIGGER
The SET TRIGGER command sets trigger parameters within the RDF configuration memory table.
The supplied values are not applied to the RDF configuration file, however, until you issue an ADD
TRIGGER command. The trigger type (REVERSE or TAKEOVER) is specified in the ADD TRIGGER
command.
SET TRIGGER trigger-option
where trigger-option is:
{PROGRAM program-file }
{INFILE infile }
{OUTFILE outfile }
{CPUS primary-CPU : alternate-CPU }
{PRIORITY priority }
{WAIT |NOWAIT }
program-file
is the name of any Guardian object file. This object file is run once RDF has reached a particular
state, either after a STOP RDF, REVERSE, or TAKEOVER operation. program-file must be
a properly-formed Guardian disk file name. The file does not have to exist. This parameter 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.
