Description

The Set-SqlErrorLog cmdlet sets or resets the maximum number of error log files before they are recycled.

This cmdlet supports the following modes of operation to set logs:

  • Pass the instance of the SQL Server.
  • Specify the Path parameter of the SQL Server instance.
  • Invoke the cmdlet in a valid context.

Examples

Example 1: Set the maximum number or error logs

PS C:\> Set-SqlErrorLog -ServerInstance "MyServer\MyInstance" -MaxLogCount 11 | Out-Null

This command sets the maximum number of error log files to 11.

Example 2: Return the TSQL script code to set the maximum number or error logs

PS C:\> Set-SqlErrorLog -ServerInstance "MyServer\MyInstance" -MaxLogCount 11 -Script

USE [master] 
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'NumErrorLogs', REG_DWORD, 11
GO

This command returns the T-SQL script code, as a string array, that is needed to set the maximum number of error log files to 11.

Parameters

-AccessToken

The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.

This can be used, for example, to connect to SQL Azure DB and SQL Azure Managed Instance using a Service Principal or a Managed Identity.

The parameter to use can be either a string representing the token or a PSAccessToken object as returned by running Get-AzAccessToken -ResourceUrl https://database.windows.net.

This parameter is new in v22 of the module.

Type:PSObject
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ConnectionTimeout

Specifies the number of seconds to wait for a server connection before a time-out failure. The time-out value must be an integer value between 0 and 65534. If 0 is specified, connection attempts do not time out.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Credential

Specifies a PSCredential object used to specify the credentials for a SQL Server login that has permission to perform this operation.

Type:PSCredential
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Encrypt

The encryption type to use when connecting to SQL Server.

This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.

In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:String
Accepted values:Mandatory, Optional, Strict
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ErrorLogSizeKb

Specifies the size limit of the SQL instance error log file in kilo bytes.

Valid range is 0 to Int32.MaxValue.

If the user does not specify this parameter then the ErrorLogSizeKb remains unchanged. The default value for the SQL instance is 0.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-HostNameInCertificate

The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.

This parameter is new in v22 of the module.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-InputObject

Specifies the server object of the target instance.

Type:Server
Position:1
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-MaxLogCount

Specifies the maximum number of error log files. If the value is not specified, the cmdlet resets the value to the default.

The allowed range of values are between 6 and 99.

Type:UInt16
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Path

Specifies the path to the instance of SQL Server on which this cmdlet runs the operation. If you do not specify a value for this parameter, the cmdlet uses the working location.

Type:String
Position:1
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ProgressAction

Determines how PowerShell responds to progress updates generated by a script, cmdlet, or provider, such as the progress bars generated by the Write-Progress cmdlet. The Write-Progress cmdlet creates progress bars that show a command's status.

Type:ActionPreference
Aliases:proga
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Script

Indicates that this cmdlet returns a Transact-SQL script that performs the task that this cmdlet performs.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ServerInstance

Specifies, as a string array, the name of an instance of SQL Server. For default instances, only specify the computer name: MyComputer. For named instances, use the format MyComputer\MyInstanceName.

Type:String[]
Position:1
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-TrustServerCertificate

Indicates whether the channel will be encrypted while bypassing walking the certificate chain to validate trust.

In v22 of the module, the default is $true (for compatibility with v21). In v23+ of the module, the default value will be '$false', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

System.String[]

Microsoft.SqlServer.Management.Smo.Server

Notes

If the value on the server is already set to the value specified, this cmdlet does not do anything.
