###

    import com.sleepycat.db.*;

    public void log_flush(DbLsn lsn)
    	throws DbException;

# Description

The DbEnv.log_flush method guarantees that all log records whose DbLsn values are less than or equal to the lsn argument have been written to disk. If lsn is null, all records in the log are flushed.

The DbEnv.log_flush method throws an exception that encapsulates a non-zero error value on failure.

# Errors

The DbEnv.log_flush 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.

The DbEnv.log_flush 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.log_flush method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
