如何截断和缩小日志文件？

Question

How to truncate and shrink large log files in SQL Server 2005? How to apply truncation at regular intervals?

Is there any difference between truncation and shrinking?

Thanks in advance

Answer 1

Use DBCC SHRINKFILE and schedule it as a job that runs regularly (preferably during off-hours).

Just be aware that there is a performance hit from regularly growing and shrinking the log file. If you have the space, you may want to set the file size to the maximum that it normally grows to and just leave it.

Answer 2

使用DBCC SHRINKFILE语句。

Answer 3

Reliable shrinking is achieved by

• Backup (can be truncate only)
• Checkpoint
• Shrink
