SharePoint 2013 Visio Web Access Web part Error. The Server Failed to process the request.
You can resolve the above problem by giving service account (sp_services)
sysadm role in SQL Database.
How to find the service account which needs db_owner in SQL
Db.??
Run the following commands in powershell. to find out what is the service ID
Get-SPServiceApplicationPool | Select Id, Name
Get-SPServiceApplicationPool -Identity "SharePoint
Hosted Services"
I got the service ID which is used for SharePoint Hosted
Services. And that is svc_spp_service on the My server.
I logged into SQL database and give access to this
svc_Spp_service ID sysadmin access in MS SQL server. And my problem was solved.
