Description

The SqlProtocol DSC resource manages the SQL Server protocols for a SQL Server instance.

For more information about protocol properties look at the following articles:

• TCP/IP Properties (Protocols Tab).
• Shared Memory Properties.
• Named Pipes Properties.

Requirements

• Target machine must be running Windows Server 2012 or later.
• Target machine must be running SQL Server Database Engine 2012 or later.
• Target machine must have access to the SQLPS PowerShell module or the SqlServer PowerShell module.
• If a protocol is disabled that prevents the cmdlet Restart-SqlService from contacting the instance to evaluate if it is a cluster. If this is the case then the parameter SuppressRestart must be used to override the restart. It is the same if a protocol is enabled that was previously disabled and no other protocol allows connecting to the instance, then the parameter SuppressRestart must also be used.
• When connecting to a Failover Cluster where the account SYSTEM does not have access then the correct credential must be provided in the built-in parameter PSDscRunAsCredential. If not the following error can appear; An internal error occurred.
• When using the resource against an SQL Server 2022 instance, the module SqlServer v22.0.49-preview or newer must be installed.

Examples

Example 1

This example will enable the TCP/IP protocol, set the protocol to listen on all IP addresses, and set the keep alive duration.

The resource will be run as the account provided in $SystemAdministratorAccount.

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [System.Management.Automation.PSCredential]
        $SystemAdministratorAccount
    )

    Import-DscResource -ModuleName 'SqlServerDsc'

    node localhost
    {
        SqlProtocol 'ChangeTcpIpOnDefaultInstance'
        {
            InstanceName           = 'MSSQLSERVER'
            ProtocolName           = 'TcpIp'
            Enabled                = $true
            ListenOnAllIpAddresses = $false
            KeepAlive              = 20000

            PsDscRunAsCredential   = $SystemAdministratorAccount
        }
    }
}

Example 2

This example will enable the Named Pipes protocol and set the name of the pipe.

The resource will be run as the account provided in $SystemAdministratorAccount.

Configuration Example
