import com.sleepycat.db.*;public void flush(DbLsn lsn) throws DbException;
The DbLog.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 DbLog.flush method throws an exception that encapsulates an errno on failure.
The DbLog.flush method may fail and throw an exception for any of the errors specified for the following Berkeley DB and C library functions: abort(3), close(3), dbenv->db_paniccall(3), fcntl(3), fflush(3), fprintf(3), free(3), fsync(3), getenv(3), getpid(3), getuid(3), isdigit(3), lseek(3), malloc(3), memcpy(3), memset(3), open(3), sigfillset(3), sigprocmask(3), snprintf(3), stat(3), strerror(3), strlen(3), unlink(3), vfprintf(3), vsnprintf(3), and write(3).
In addition, the DbLog.flush method may fail and throw an exception encapsulating errno for the following conditions:
