Function
You can specify the rollForwardRecoveryFrom=path in
the boot time URL to restore the database using a backup copy and perform
rollforward recovery using archived and active logs.
To restore a database
using rollforward recovery, you must already have a backup copy of the database,
all the archived logs since then, and the active log files. All the log files
should be in the database log directory.
After a database is restored
from full backup, transactions from the online archived logs and the active
logs are replayed.
For more information about using this attribute, see "Roll-forward recovery"
in the Derby Server and Administration Guide.
