Unable to delete Search Service Application (SSA) in SharePoint 2010

Hello,

If you have a bull headed Enterprise Search Service Application and you can not able to delete this service application by Central Administration or fallowing powershell script
$ssa = Get-SPServiceApplication -name “<Search Service Application  Name>”
Remove-SPServiceApplication $ssa

The symptoms is when you attempt to  delete this service application powershell or web GUI is hanging  until timeout.

So you may try fallowing powershell command to force to delete:

1) Open the SharePoint PowerShell on the SharePoint server and run the following commands:
2) Run fallowing command which will list all Enterprize search applications and their GUIDs
Get-SPEnterpriseSearchServiceApplication
Take note of problematic service application guid
3) Type fallowing command:
$ssa = Get-SPEnterpriseSearchServiceApplication -id “<noted guid here>”
$ssa.unprovision(1)

if the above command is successful the SSA will be deleted, if it is hung, then try fallowing:
1) Open a new PowerShell:
2) Run fallowing command which will list all Enterprize search applications and their GUIDs
Get-SPEnterpriseSearchServiceApplication
Take note of problematic service application guid

$ssa = Get-SPEnterpriseSearchServiceApplication -id “<noted guid here>”
$ssa.Delete()

I hope this will resolve your issues.
