PowerShell - Create Search Service App Pools (All 3)

Question

1. How many App Pools are created when you create the Search Service Application?
2. How can I create all the Search Service Application App Pools using PowerShell and give them all unique names?

I've come across many scripts to create the search service application with a custom Admin App Pool name. The only thing missing in all of these scripts is the ability to also name the Query App Pool like you can do in Central Admin. I'm mainly looking to separate the App Pools and give them all unique names.

Answer 1

1. Single Application Pool / the one you indicate when you create the S-SA

2. See script

   Function Get-SPServiceApplicationPoolByName($SPApplicationPoolName, $ManagedAccount) {
   

   $appPool = Get-SPServiceApplicationPool | Where {$_.Name -eq $SPApplicationPoolName}

   if($appPool -eq $null) {
       $appPool = New-SPServiceApplicationPool -Name $SPApplicationPoolName -Account $ManagedAccount
   }
   
   Return $appPool}
   

Answer 2

There are two search-related service application pools: Admin and Query. Here are the lines of PowerShell I use in my scripts:

# Create the application pools for the Search Admin service and the Search Query service
$apppool_searchadmin = New-SPServiceApplicationPool –name $ap_search_admin –account $account_search_admin
$apppool_searchquery = New-SPServiceApplicationPool –name $ap_search_query –account $account_search_query

New-SPServiceApplicationPool will return the app pool, which I use save to the two variables and use in my script later when needed. I pass it the name of the application pool and a string that contains the account name ("DOMAIN\account") for the application pool.

You can then create the search service with New-SPEnterpriseSearchServiceApplication:

$searchApp = New-SPEnterpriseSearchServiceApplication -Name $searchServiceAppName -ApplicationPool $apppool_searchquery -AdminApplicationPool $apppool_searchadmin -DatabaseName $dbName
