| DbLsn | | public class DbLsn (Code) | | DbLsn is a class that operates on Log Sequence Numbers (LSNs). An LSN is a
long comprised of a file number (32b) and offset within that file (32b)
which references a unique record in the database environment log. While
LSNs are represented as long's, we operate on them using an abstraction and
return longs from these methods so that we don't have to worry about the
lack of unsigned quantities.

the offset for this DbLsn. |
| getNoCleaningDistance | | public static long getNoCleaningDistance(long thisLsn, long otherLsn, long logFileSize)(Code) | | Return the logsize in bytes between these two LSNs. This is an
approximation; the logs might actually be a little more or less in
size. This assumes that no log files have been cleaned.

approximation; the logs might actually be a little more or less in
size. This assumes that log files might have been cleaned.
