SqlAGDatabase

Parameters

Parameter	Attribute	DataType	Description	Allowed Values
DatabaseName	Required	StringArray[]	The name of the database(s) to add to the availability group. This accepts wildcards.
ServerName	Key	String	Hostname of the SQL Server where the primary replica of the availability group lives. If the availability group is not currently on this server, the resource will attempt to connect to the server where the primary replica lives.
InstanceName	Key	String	Name of the SQL Server instance where the primary replica of the availability group lives. If the availability group is not currently on this instance, the resource will attempt to connect to the instance where the primary replica lives.
AvailabilityGroupName	Key	String	The name of the availability group in which to manage the database membership(s).
BackupPath	Required	String	The path used to seed the availability group replicas. This should be a path that is accessible by all of the replicas.
Ensure	Write	String	Specifies the membership of the database(s) in the availability group. The option 'Present' means that the defined database(s) are added to the availability group. All other databases that may be a member of the availability group are ignored. The option 'Absent' means that the defined database(s) are removed from the availability group. All other databases that may be a member of the availability group are ignored. The default is 'Present'.	Present, Absent
Force	Write	Boolean	When parameter Ensure is set to 'Present' it ensures the specified database(s) are the only databases that are a member of the specified Availability Group. This parameter is ignored when parameter Ensure is set to 'Absent'.
MatchDatabaseOwner	Write	Boolean	If set to $true, this ensures the database owner of the database on the primary replica is the owner of the database on all secondary replicas. This requires the database owner is available as a login on all replicas and that the PsDscRunAsCredential has impersonate any login, control server, impersonate login, or control login permissions. If set to $false, the owner of the database will be the username specified in PsDscRunAsCredential. The default is $false.
ReplaceExisting	Write	Boolean	If set to $true, this adds the restore option WITH REPLACE. If set to $false, existing databases and files will block the restore and throw error. The default is $false.
ProcessOnlyOnActiveNode	Write	Boolean	Specifies that the resource will only determine if a change is needed if the target node is the active host of the SQL Server instance.
StatementTimeout	Write	SInt32	Set the query timeout in seconds for the backup and restore operations. The default is 600 seconds (10mins).
IsActiveNode	Read	Boolean	Returns if the current node is actively hosting the SQL Server instance.

Description

The SqlAGDatabase DSC resource is used to add databases or remove databases from a specified availability group. When a replica has Automatic seeding on Automatic, no restore is use for that replica. When all replicas are on automatic seeding, no backup is made, unless the database has never been backuped.

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 be running Windows Management Framework (WMF) 5 or later.

Examples

Example 1

This example shows how to ensure that the databases 'DB*' and 'AdventureWorks' are members of the Availability Group 'TestAG'.

In the event this is applied to a Failover Cluster Instance (FCI), the ProcessOnlyOnActiveNode property will tell the Test-TargetResource function to evaluate if any changes are needed if the node is actively hosting the SQL Server Instance.

Configuration Example

    param
    (
        [Parameter(Mandatory = $true)]
        [System.Management.Automation.PSCredential]
        $SqlAdministratorCredential
    )

    Import-DscResource -ModuleName 'SqlServerDsc'

    Node $AllNodes.NodeName
    {
        SqlAGDatabase 'AddAGDatabaseMemberships'
        {
            AvailabilityGroupName   = 'TestAG'

            InstanceName            = 'MSSQLSERVER'

Example 2

This example shows how to ensure that the databases 'DB*' and 'AdventureWorks' are not members of the Availability Group 'TestAG'.
