I wanted to remove the existing search service applications in my SP 2013 Farm. For that I directed my juniors to delete the same from central admin, but they could not delete. The entries were still there. So, they went to Sql Server and deleted all the search service application related databases using Sql Management Studio.
Now, when they came back to central admin, manage service applications page, all the search service applications were still available . When they tried to Delete the same again, but got another kind of error.
Sorry, something went wrong Cannot open database "Search_Service_Application_DB_a995b3c88ca94d63963387a519011088" requested by the login. The login failed. Login failed for user 'mydomain1\mmuser1'
How to resume deleting the same Search service applns from Central Admin.
