Command Overview
START RDF
The START RDF command starts RDF.
UPDATE ON
enables update processing on the backup system; this is the default value.
UPDATE OFF
disables update processing on the backup system.
RDF image files are not purged from the backup system.
Where Issued
Primary system only.
Security Restrictions
You can issue the START RDF command only if you are the member of the super-user
group that initialized RDF and have remote passwords on both the primary and backup
systems.
RDF State Requirement
You can issue the START RDF command only after TMF has been started and RDF
has been previously initialized.
Usage Guidelines
The decision to start RDF is a management decision that should be carefully planned
and performed. Operators should never issue this command strictly on their own
initiative.
For information about when to use the START RDF command and how it affects the
primary and backup databases, see Restarting RDF in section 5.
If you have initialized the TMF and RDF subsystems before issuing the START RDF
command, RDF automatically begins transmitting audit data from the beginning of the
first audit trail file.
Transaction processing need not be enabled on the primary system, however, when
you enter the START RDF command; it is enough that TMF has been started before
you issue this command.
START RDF [, UPDATE {ON | OFF}]
Caution. If you initialize RDF after a STOP RDF command is issued at the primary system,
you may need to resynchronize the databases before restarting RDF.
