Command Overview
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 above. NOW causes RDF to be initialized at
the current date and time. NOW is designed specifically for use with REVERSE
operations. NOW simplifies initialization and configuration of a reverse RDF
environment created in response to a reverse trigger. See the Example for the
SET TRIGGER command.
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 extractors 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 Initializating RDF Without Stopping TMF and Online Installation and
Initialization Without Stopping RDF for a description of this feature.
