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.

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments: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.

-Credential

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

Parameter properties

Type:PSCredential
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

ByName
Position:Named
Mandatory:False
Value from pipeline: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.

-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.

-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.

DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
