Description

Type: Distributed Requires CredSSP: No

This resource is responsible for provisioning the search service application. The current version lets you specify the database name and server, as well as the application pool. If the application pool is changed the DSC resource will set it back as per what is set in the resource. The database name parameter is used as the prefix for all search databases (so you will end up with one for the admin database which matches the name, and then "_analyticsreportingstore", "_crawlstore" and "_linkstore" databases as well).

The default value for the Ensure parameter is Present. When not specifying this parameter, the service application is provisioned.

For more information about the Deletion Policy settings, check the following article: https://docs.microsoft.com/en-us/previous-versions/office/sharepoint-server-2010/hh127009(v=office.14)?redirectedfrom=MSDN

NOTE: Don't forget to configure a Search topology using the SPSearchTopology resource!

NOTE2: The resource is also able to add the Farm account as db_owner to all Search databases, to prevent the issue described here: https://www.techmikael.com/2014/10/caution-if-you-have-used.html Use the FixFarmAccountPermissions parameter to implement this fix (default $true if not specified).

Examples

Example 1

This example creates a new search service app in the local farm

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [PSCredential]
        $SetupAccount
    )

    Import-DscResource -ModuleName SharePointDsc

    node localhost
    {
        SPSearchServiceApp SearchServiceApp
        {
            Name                 = "Search Service Application"
            DatabaseName         = "SP_Search"
            ApplicationPool      = "SharePoint Service Applications"
            PsDscRunAsCredential = $SetupAccount
        }
    }
}

Example 2

This example removes a search service app in the local farm. The ApplicationPool parameter is still required but is not actually used, so its value does not matter.

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [PSCredential]
        $SetupAccount
    )

    Import-DscResource -ModuleName SharePointDsc

    node localhost
    {
        SPSearchServiceApp SearchServiceApp
        {
            Name                 = "Search Service Application"
            Ensure               = "Absent"
            ApplicationPool      = "n/a"
            PsDscRunAsCredential = $SetupAccount
        }
    }
}

Example 3

This example creates a new search service app in the local farm

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [PSCredential]
        $SetupAccount
    )

    Import-DscResource -ModuleName SharePointDsc

    node localhost
    {
        SPSearchServiceApp SearchServiceApp
        {
            Name                       = "Search Service Application"
            DatabaseName               = "SP_Search"
            ApplicationPool            = "SharePoint Service Applications"
            ProxyName                  = "Search Service Application Proxy"
            SearchCenterUrl            = "https://intranet.contoso.com/sites/search"
            AlertsEnabled              = $true
            ErrorDeleteCountAllowed    = 10
            ErrorDeleteIntervalAllowed = 240
            ErrorCountAllowed          = 15
            ErrorIntervalAllowed       = 360
            DeleteUnvisitedMethod      = 1
            RecrawlErrorCount          = 5
            RecrawlErrorInterval       = 120
            Ensure                     = "Present"
            PsDscRunAsCredential       = $SetupAccount
        }
    }
}
