Sets tempdb data and log files according to best practices.
Calculates tempdb size and file configurations based on passed parameters, calculated values, and Microsoft best practices. User must declare SQL Server to be configured and total data file size as mandatory values. Function then calculates the number of data files based on logical cores on the target host and create evenly sized data files based on the total data size declared by the user.
Other parameters can adjust the settings as the user desires (such as different file paths, number of data files, and log file size). No functions that shrink or delete data files are performed. If you wish to do this, you will need to resize tempdb so that it is "smaller" than what the function will size it to before running the function.

PS C:\> Set-DbaTempDbConfig -SqlInstance localhost -DataFileSize 1000
Creates tempdb with a number of data files equal to the logical cores where each file is equal to 1000MB divided by the number of logical cores, with a log file of 250MB.
PS C:\> Set-DbaTempDbConfig -SqlInstance localhost -DataFileSize 1000 -DataFileCount 8
Creates tempdb with 8 data files, each one sized at 125MB, with a log file of 250MB.
PS C:\> Set-DbaTempDbConfig -SqlInstance localhost -DataFileSize 1000 -OutputScriptOnly
Provides a SQL script output to configure tempdb according to the passed parameters.
PS C:\> Set-DbaTempDbConfig -SqlInstance localhost -DataFileSize 1000 -DisableGrowth
Disables the growth for the data and log files.
PS C:\> Set-DbaTempDbConfig -SqlInstance localhost -DataFileSize 1000 -OutputScriptOnly
Returns the T-SQL script representing tempdb configuration.
The target SQL Server instance or instances.
| Alias | |
| Required | True |
| Pipeline | false |
| Default Value |
Specifies the total data file size in megabytes. This is distributed across the total number of data files.
| Alias | |
| Required | True |
| Pipeline | false |
| Default Value | 0 |
Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies the number of data files to create. If this number is not specified, the number of logical cores of the host will be used.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | 0 |
Specifies the log file size in megabytes. If not specified, no change will be made.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | 0 |
Specifies the growth amount for the data file(s) in megabytes. The default is 512 MB.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | 512 |
Specifies the growth amount for the log file in megabytes. The default is 512 MB.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | 512 |
Specifies the filesystem path(s) in which to create the tempdb data files. If not specified, current tempdb location will be used.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies the filesystem path in which to create the tempdb log file. If not specified, current tempdb location will be used.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies the filesystem path into which the generated T-SQL script will be saved.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
If this switch is enabled, only the T-SQL script to change the tempdb configuration is created and output.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, the tempdb files will be configured to not grow. This overrides -DataFileGrowth and -LogFileGrowth.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
| Alias | wi |
| Required | False |
| Pipeline | false |
| Default Value |
If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
