Is it safe to delete tempdb MDF?
3 Answers. No, you cannot delete the tempdb mdf file. If you need to shrink the file again, restart SQL Server, and then run DBCC SHRINKFILE() . This is a supported operation, unlike any of this “delete an mdf file while SQL Server is not looking” voodoo.
How many TempDB files should you have?
The general recommendation is that it should be equal to logical processors, if less than 8 else configure it to 8 files. For example, if we have a dual-core processor, then set the number of TempDB data files equal to two. If we have more than 8 cores, start with 8 files and add four at a time as needed.
How many TempDB should I have?
It is recommended that you have one TempDB data file per CPU core. For example a server with 2 duel core processors would recommend 4 TempDB data files. With that in mind, Microsoft recommends a maximum of 8 TempDB files per SQL Server.
How to remove a tempdb file in SQL Server?
The question which I often receive is about how to add TempDB files in SQL Server but I have never received a question about how to remove a TempDB file. One of the DBA accidently added an additional TempDB file to their setup and had no idea what to do next to go back to the original situation.
How often do I need to use tempdb?
I am fortunate to work on different challenges every week for SQL Server Performance Tuning. The other day I ended up a very interesting situation while working with Comprehensive Database Performance Health Check, with TempDB files.
Is it possible to move 32 tempdb files?
Now moving the database to another drive was not possible because the other drive had 32 tempdb files. After careful investigation, we realized that over 97% of the TempDB was empty and they were just occupying big space as they were pre-sized initially. Additionally, looking at the 32 TempDB was absolutely not needed.
Why are my tempdb files getting too big?
If your files become too large – for example if your tempdb files are properly pre-sized and they grow because of some bad queries that spill in tempdb, etc., – then you can SHRINK the files to get them back the appropriate size. But in this situation, I mistakenly ran a query that ADDED files and pre-sized them and filled up a drive.
