When the preceding command sequence is executed, all of the other RDF global parameters are
set to their default values: (In this list, \LONDON is the system at which you issued the command
sequence.)
PRIMARYSYSTEM: \LONDON
CONTROL SUBVOLUME: LONDON
LOGFILE : $0
UPDATERDELAY: 10
UPDATEROPEN: PROTECTED
UPDATEREXCEPTION: ON
UPDATERTXTIME: 60
UPDATERRTDWARNING: 60
NETWORK: OFF
NETWORKMASTER: OFF
REPLICATEPURGE: OFF
LOCKSTEPVOL: (omitted)
OWNER: (omitted)
Suppose you want to protect the volume $DATA01 on the primary system by configuring an
updater process for the volume $DATA1 and secondary image trail $SECIT1 on the backup
system (assuming that $SECIT1 was previously added to the RDF configuration by way of an
ADD IMAGETRAIL command). Also suppose the updater process is to be named $UP01, is to
run in CPUs 2 and 3 of the backup system at the default priority of 160. In this example, we
assume the ATINDEX value to be the default value of zero. To configure the updater process,
enter the following commands:
]SET VOLUME PROCESS $UP01
]SET VOLUME CPUS 2:3
]SET VOLUME MAPFILE $DATA05.CONFIG.MAPFILE
]SET VOLUME MAPLOG $DATA05.LOG.MAPLOG
]SET VOLUME UPDATEVOLUME $DATA1
]SET VOLUME IMAGEVOLUME $SECIT1
]ADD VOLUME $DATA01
The SET VOLUME commands supply only values that pertain to the backup system environment;
it is not until you issue an ADD VOLUME command that the updater process actually becomes
associated with a particular volume on the primary system.
To define a reverse trigger, enter a command sequence such as:
SET TRIGGER PROGRAM $SYSTEM.RDF.RDFCOM
SET TRIGGER INFILE $DATA01.RDFCONF.RIGHT
SET TRIGGER OUTFILE $0
SET TRIGGER WAIT
SET TRIGGER CPU 0:1
SET TRIGGER PRIORITY 150
ADD TRIGGER REVERSE
ALTER
The ALTER command changes the setting of the specified parameter in the RDF configuration
file to the supplied value.
