public void set_tx_timestamp(java.util.Date timestamp) throws DbException;
Recover to the time specified by timestamp rather than to the most current possible date. Note that only the seconds (not the milliseconds) of the timestamp are used
Once a database environment has been upgraded to a new version of Berkeley DB involving a log format change (see Upgrading Berkeley DB installations), it is no longer possible to recover to a specific time before that upgrade.
The DbEnv.set_tx_timestamp interface may be used only to configure Berkeley DB before the DbEnv.open interface is called.
The DbEnv.set_tx_timestamp method throws an exception that encapsulates a non-zero error value on failure.
The DbEnv.set_tx_timestamp method may fail and throw an exception encapsulating a non-zero error for the following conditions:
It is not possible to recover to the specified time using the log files currently present in the environment.
The DbEnv.set_tx_timestamp method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv.set_tx_timestamp method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
