Under any of these circumstances, SQL Server truncates the database s transaction log every time it gets full enough. (I ll explain this in a moment.) The database is considered to be in autotruncate mode. Remember that truncation means that all log records prior to the oldest active transaction are invalidated and all VLFs not containing any part of the active log are marked as reusable. It does not imply shrinking of the physical log le. In addition, if your database is a publisher in a replication scenario, the oldest open transaction could be a transaction marked for replication that has not yet been replicated. Full enough means that there are more log records than can be redone during system startup in a reasonable amount of time the recovery interval. You can change the recovery interval manually by using the sp_con gure stored procedure or by using SQL Server Management Studio, as discussed in 1. However, it is best to let SQL Server autotune this value. In most cases, this recovery interval value is set to one minute. By default, sp_con gure shows zero minutes, meaning SQL Server autotunes the value. SQL Server bases its recovery interval on the estimate that 10 MB worth of transactions can be recovered in one minute. qr code reader c# .net NET QR Code Barcode Reader - KeepAutomation.com

It's an easy task to use Visual Basic . NET code to scan QR Code barcodes from a image file. One line free VB code can achieve this. With this simple VB code , you can read and output all QR Code barcodes data in " qrcode - vbnet .gif" image file at a time. The actual log truncation is invoked by the checkpoint process, which is usually sleeping and is awakened only on demand. Each time a user thread calls the log manager, the log manager checks the size of the log. If the size exceeds the amount of work that can be recovered during the recovery interval, the checkpoint thread is woken up. The checkpoint thread checkpoints the database and then truncates the inactive portion of the log. In addition, if the log ever gets to 70 percent full while the database is in autotruncate mode, the log manager wakes the checkpoint thread to force a checkpoint. Growing the log is much more expensive than truncating it, so SQL Server truncates the log whenever it can. open source qr code reader vb.net . NET Barcode Scanner Library API for .

The Web, the Internet, and XML have changed many fundamental business assumptions Core competencies gain value from the marketplace If a competency is a commodity, then something else is needed to provide differentiation and value In the Information Age, core competencies change as quickly as business and technology A corporation s core competency, from the customer perspective the only one of importance may provide high value in yesterday s market place but may be diminished by tomorrow s new technology A good example of this is the slide rule; as soon as calculators became cheaply available, they supplanted slide rules, which are now dinosaurs of a distant past Technology changes competency truncation never happens. If you have a database in autotruncate mode, for which the transaction log has VLFs with a status of 2, you do not see the status change to 0 until some logging activity is required in the database. If the log is regularly truncated, SQL Server can reuse space in the physical le by cycling back to an earlier VLF when it reaches the end of the physical log le. In effect, SQL Server recycles the space in the log le that is no longer needed for recovery or backup purposes. My AdventureWorks2008 database is in this state because I have never made a full database backup. 1. At the very top of Main.cs, add the following using statements: the indexes or only one particular index. If we make the third parameter NULL to specify all indexes, we can then add a lter in a WHERE clause to indicate that we want only nonclustered index rows (WHERE index_id > 1). Note that while a WHERE clause may limit the number of rows returned it does not necessarily limit the tables and indexes analyzed. The DBCC IND command (introduced in 5, Tables ) is undocumented but widely known and used. It is safe to use on production systems. The command has four parameters, but only the rst three are required. The following code shows the command syntax: DBCC IND ( { 'dbname' | dbid }, { 'objname' | objid }, { nonclustered indid | 1 | 0 | -1 | -2 } [, partition_number] The rst parameter is the database name or the database ID. The second parameter is an object name or object ID within the database; the object can be either a table or an indexed view. The third parameter is a speci c nonclustered index ID (2-250 or 256-1005) or the values 1, 0, 1, or 2. The values for this parameter have the following meanings: 2.
