Move SQL Tempdb files – Common errors
October 5, 2015
Run query on the correct database
EXEC sp_helpfile GO
Tip: you can also view it under properties.
USE master; GO ALTER DATABASE tempdb MODIFY FILE (NAME = tempdev, FILENAME = ‘F:\MSSQL\DATA\tempdb.mdf’); GO
ALTER DATABASE tempdb MODIFY FILE (NAME = templog, FILENAME = ‘F:\MSSQL\DATA\templog.ldf’); GO
Restart sql services: ‘stop and start’
The file “tempdev” has been modified in the system catalog. The new path will be used the next time the database is started.
The file “templog” has been modified in the system catalog. The new path will be used the next time the database is started.
rerun the sp query to verify the correct location fort he tempdb files
Now delete the old files or in my case rename them before finally remove them.
Next we are gonna change the properties for the autogrowth.
