RDF System Management Manual for J-series and H-series RVUs (RDF Update 13)

month
is the first three letters of the month, such as JAN, FEB, MAR.
year
is a four-digit number greater than 1996.
hour
is a number from 0 to 23.
min
is a number from 00 to 59. min must be preceded by a colon (:).
INITTIME <day><mon><year><hour>:<min> | NOW
is a timestamp used for online product initialization. It has the same format as the timestamp
parameter described. NOW causes RDF to be initialized at the current date and time.
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 records to the backup system and the updaters had applied it to the backup database.
This practice guarantees that no audit records are lost during reinitialization.
See “Initializing RDF Without Stopping TMF (Using INITTIME Option)” (page 69) and “Online
Installation and Initialization Without Stopping RDF” (page 71) for a description of this feature.
The NOW option should only be used with REVERSE operations. NOW simplifies initialization
and configuration of a reverse RDF subsystem that is created during the execution of a reverse
trigger. See the example in the discussion of the “SET TRIGGER” (page 226).
SYNCHDBTIME <day><mon><year><hour>:<min>
is a timestamp used for online database synchronization. It has the same format as the timestamp
parameter described.
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/IMP, IMPX, or ZLT is installed on both
the primary and backup systems.
For a description of the online synchronization feature, see Chapter 7 (page 157).
!
causes the command to be executed without further confirmation. If you omit the exclamation
point, RDFCOM prompts you for additional responses:
• 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.
• If you include the TIMESTAMP option without the ! option, RDFCOM displays:
Do you wish to proceed? [Y/N]
Enter Y or YES to proceed; enter N or NO to cancel the command.
If you enter Y or YES, RDFCOM displays:
