MS SQL Server - Shrinking transaction logs

Shrinking transaction logs

Run the script below to shrink the database's transaction log. Please note that logs should not really need to be shrank. If logs are not needed, on the database options set the database recovery model to simple this process (see below).

MS SQL Server 2005 

use database_name

backup log progress with truncate_only
dbcc shrinkfile ('transaction_logical_filename')


MS SQL Server 2008 and above

Microsoft SQL Server 2008 does not support the backup with truncate_only directive. So to truncate a log in 2008, run the following script.

BACKUP LOG database_name TO DISK='NULL'

Please endure that the database recovery model is set to full (see below) and a database full back up has been run.

MS SQL Server - Moving temp DB location

Moving the temp DB location

The script below will move the temp db from its current location to the new location (highlighted). Please ensure you change the logical file name (also highlighted) .

use master
go
Alter database tempdb modify file (name = tempdev, filename = 'E:\Sqldata\tempdb.mdf')
go
Alter database tempdb modify file (name = templog, filename = 'E:\Sqldata\templog.ldf')
go


After running the above script you will need to restart the MS SQL Server Service for the changes to take effect.

Note This script creates two stored procedures in the master database. The procedures are named:

• sp_hexadecimal 
• sp_help_revlogin.

On the Source SQL Server instance, run the following statement:

EXEC sp_help_revlogin

The output script that the sp_help_revlogin stored procedure generates is the login script. This login script creates the logins that have the original Security Identifier (SID) and the original password.
On server B, start SQL Server Management Studio, and then connect to the instance of SQL Server to which you moved the database.

Open a new Query Editor window on the target SQL Server instance, and then run the output script.
