Command Overview
min
is a number from 00 to 59. min must be preceded by a colon (:).
INITTIME <day><mon><year><hour>:<min>
is a timestamp used for online product initialization. It has the same format as the
timestamp parameter described above.
To determine the appropriate value to use as the inittime parameter, first issue an
RDFCOM STATUS RDF command and take note of the highest updater RTD time.
Then round that RTD time up to the next highest minute internal (0:43 becomes
1:00, 1:27 becomes 2:00, 3:04 becomes 4:00, and so forth). Finally, subtract that
rounded-up time from the current system time as shown in the status display.
inittime := (current-system-time — rounded-highest-updater-RTD-time)
RDFCOM then subtracts an additional three minutes from the specified time stamp.
This is to ensure that the extractor’s starting position is at a point in the MAT where
RDF had previously sent audit information to the backup system and the updaters
had applied it to the backup database. This practice guarantees that no audit
information will be lost during reinitialization.
See Online Product Initialization
for a description of this feature.
SYNCHDBTIME <day><mon><year><hour>:<min>
is a timestamp used for online database synchronization. It has the same format as
the
timestamp parameter described above.
There are no special considerations for specifying the synchdbtime parameter,
except that it must designate a time earlier than the present time.
The SYNCHDBTIME parameter can only be used if RDF/MPX or IMPX is
installed on both the primary and backup systems.
For a description of the online synchronization feature, see Section 7, Online
Database Synchronization.
!
causes the command to be executed without further confirmation. If you omit the
exclamation point, RDFCOM prompts you for additional responses as follows:

If you omit the TIMESTAMP, INITTIME, SYNCHDBTIME, and ! options,
RDFCOM displays:
Are you sure you want to initialize? [Y/N]
Enter Y or YES to proceed; enter N or NO to cancel the command.
