Parameters
DBEnvironmentName is the name of a DBEnvironment.
MaintenanceWord is the maintenance word.
Description
* This command starts a DBEnvironment session, and terminates a
rollforward recovery process after all relevant log files have
been applied in sequence.
* Rollforward recovery uses four commands:
* SETUPRECOVERY--initiates the process.
* RESTORELOG--restores a log file from a backup.
* RECOVERLOG--issued by you for each log file being applied
to the DBEnvironment.
* ENDRECOVERY--ends the rollforward recovery process.
* You normally apply SETUPRECOVERY once. You can specify a
RecoverTime as the end point for recovery. You then use
RESTORELOG to restore each backup log file to the system in
sequence number order, and you use RECOVERLOG once for each log
file that you have restored, to apply it to the DBEnvironment.
ALLBASE/SQL will recover the transactions in the file up to the
RecoverTime you specified, or up to the end of the file. You use
ENDRECOVERY once after recovering all the log files you wish to
apply to the DBEnvironment. Normally, you do not use ENDRECOVERY
if you specified a RecoverTime in the SETUPRECOVERY command.
* ENDRECOVERY will result in an error if you have not recovered
enough files to make the DBEnvironment consistent. If you used
STOREONLINE to do an online backup of the DBEnvironment, you must
recover starting from the First Log Sequence Number Needed for
Recovery up to and including the file that was active at the time
the last STOREONLINE command completed. If you did a static
backup of the DBEnvironment, you can recover as little or as much
of the log as you desire once you have restored the most recent
copy of the DBEnvironment.
Authorization
You must be the DBECreator or supply the correct maintenance word to use
this command.
