SQL Server 2008 收縮日誌

若是SQL SERVER 日誌過大，好比，達到了幾十個G，想一次性收縮的，直接執行下面命令便可：

USE DATABASENAME;

GO

– Truncate the log by changing the database recovery model to SIMPLE.

ALTER DATABASE DATABASENAME

SET RECOVERY SIMPLE;

GO

– Shrink the truncated log file to 1 MB.

DBCC SHRINKFILE (DATABASENAME_Log, 1);

GO

– Reset the database recovery model.

ALTER DATABASE DATABASENAME

SET RECOVERY FULL;

GO

正常來說，應該是先執行一次備份事務日誌，而後在執行數據庫收縮命令，就能正常的收縮日誌大小了。

一、定時執行備份事務日誌，天天凌晨1點執行

BACKUP LOG [uiyi] TO DISK = N’F:\DB_Backup\Log\uiyi\uiyi_backup_2013_06_21_145209_5008471.trn’ WITH NOFORMAT, NOINIT, NAME = N’uiyi_backup_2013_06_21_145209_4948467′, SKIP, REWIND, NOUNLOAD, STATS = 10

二、收縮日誌，天天凌晨2點執行

use uiyi

go

DBCC SHRINKFILE (uiyi1224_Log, 50);

三、備份全量數據庫，天天凌晨3點執行

BACKUP DATABASE [uiyi] TO DISK = N’F:\DB_Backup\All\uiyi\uiyi_backup_2013_06_21_145557_3298781.bak’ WITH NOFORMAT, NOINIT, NAME = N’uiyi_backup_2013_06_21_145557_3268780′, SKIP, REWIND, NOUNLOAD, STATS = 10

GO
