 | CAUTION:
In order for an online backup to be of use for rollforward recovery,
all logs containing transactions that were
active during the execution of the STOREONLINE command
must be available at recovery time.
Without all the logs, the
backup is worthless. This means that
after the STOREONLINE command completes, you should do a
STORELOG as soon as possible on any
log files that contained active transactions during
the time you did the STOREONLINE. The range of sequence numbers of the log files containing transactions
active during the STOREONLINE process is indicated at the completion
of STOREONLINE. Both the beginning and ending archive log sequence
numbers are displayed. You must store all log files in that range
to be able to do roll forward recovery, later. If there is a media failure involving the device containing the
log files active during the STOREONLINE,
and if the failure occurs before the files
have been backed up, the DBEnvironment backup will not be usable.
For the greatest protection, use dual logging with the dual files
on different disk drives. |
