Best Practices

The following are best practices from this chapter:

• Ensure that the Visio Graphics Service is set up in conjunction with the Secure Store Service before starting development. Unattended Service Account will only work when Secure Store Service Application is created. Unattended Service Account helps with refreshing data from an external data source.
  
  
• To avoid all possible configuration issues, pay careful attention to the Visio configuration chapter (Chapter 11). Do not delete any web drawing from your SharePoint site until you are sure that web drawing is not configured to be accessed from a Visio Web Access web part.
  
  
• Make sure the data provider you are using in your web drawing is listed in a trusted data provider list.
  
  
• Monitor network activities to make sure there are no connectivity issues between all servers used to configure your SharePoint farm.
