Problem
In Notes Domino Release 5.x there is a current limitation of 4 GB of transactional log extents when using Circular mode. This gives many customers close to or less than 24 hours of logging. This limit is also wasteful when transactional logging is on a very large drive where the remaining disk space cannot be used. Has this changed in Notes Domino 6?
Solution
In Notes Domino 6 a new logging style has been implemented called linear looping. This is the same scheme as circular (one set of transaction logs which is reused), but allows unlimited size.
Supporting Information:
From a backup standpoint, the linear looping style should be considered equivalent to circular. That is to say, archival of extents is not supported with linear style logging. The benefit to the user is that it extends the size of the log before extents are reused, affording a larger time window within which standard database backups can be recovered using log extents that are still available in the transaction log directory.
Only circular type logging has a limit on the log size of 4 GB. There is, in fact, no limit in size to the transaction log when using archive or linear style logging other than the amount of available disk space. In Domino version 6 the 'Maximum log space' field on the Transactional Logging tab of the Server document is no longer used with Archive transactional logging. It is used only for Circular and Linear. Although it is unnecessary to limit the log size with linear style logging, you can do so by specifying any size in the 'Maximum log space' field up to the size of the disk that is used to back the txn logs. Be aware that it will format the number of extents that will fit in the space that is specified. For example, if you specify 200 GB for the logs, you will have to wait for the 200 GB of logs to format at start up time.
Note: In R5, Archive logging can workaround the 4 GB size limitation which can accommodate any size logs up to the size of the drive. However, a utility must be used to archive the extents. Archive mode is also available in Notes Domino 6.
