from file AA000010 to file AA000013. Files AA000010 through AA000012 might no longer needed,
but, because the RETAINCOUNT is set to three, the purger process can only purge AA000010
(it must keep AA000011 and AA000012 on disk). Thus, as long as the RTD times of the extractors
on the two backup systems are less than 24 hours apart, the triple contingency protocol will work
successfully.
Similarly, if you believe the two receiver processes will never be more than 36 hours apart in
their RDF processing and your image trail file sizes are such that approximately 20 rollovers
occur every 24 hours, then you should set the RETAINCOUNT to 31 on both backup systems.

Where Issued

Primary system only.

Security Restrictions

None.

RDF State Requirements

None.

Usage Guidelines

The SET PURGER command enters the parameter values specified for the purger 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.

Example

To configure a purger process named $PRG to run in CPUs 0 and 1 with a RETAINCOUNT of
8, issue these commands:
]SET PURGER PROCESS $PRG
]SET PURGER CPUS 0:1
]SET PURGER RETAINCOUNT 8
]ADD PURGER
By default, in this example the purger process will run at a priority of 165 and the purger
purgetime is set to 60 minutes.

SET RDF

The SET RDF command sets RDF global configuration parameters within the RDF configuration
memory table. The supplied values are not applied to the RDF configuration file, however, until
you issue an ADD RDF command.
