Berkeley DB: DbEnv.set_tx_timestamp
DbEnv.set_tx_timestamp
|
 
|
import com.sleepycat.db.*;
public void set_tx_timestamp(java.util.Date timestamp)
throws DbException;
Description
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.
Errors
The DbEnv.set_tx_timestamp method may fail and throw an exception encapsulating a non-zero error for the following conditions:
- EINVAL
- An invalid flag value or parameter was specified.
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.
