This applies to: Managed Dashboards, Managed Reports This article describes the dbi.config file used to define pieces of information needed to start the application. This is initially configured as part of the installation process.

​
Application Database Connection String

The connection string that Symphony uses to connect to its application database is defined in the connectionStrings element: 
<connectionStrings>
  <add
  name="AppConnectionString"
  connectionString="Data Source=localhost;Initial Catalog=&quot;Dundas BI Instance1&quot;;User ID=DundasUser;Password=1234"
 />
</connectionStrings>
If this section is encrypted, it can be decrypted using the dt command line tool. See Using the dt Command Line Tool. Symphony can use either a Microsoft SQL Server database or a PostgreSQL database to store its application data, and connection strings are defined differently for each. For syntax details including available parameters/keywords, see Microsoft Docs for SQL Server or Npgsql for PostgreSQL.
Note: The warehouse database connection string can be changed from the configuration settings while logged in as an administrator. Its connection string uses the same syntax.

​
Application Storage Type

The ApplicationStorage key should be set to the type of database you are using. Below is an example of how this would look for SQL Server: 
<!-- The type of database server hosting the Application database.
Can be "SqlServer" or "Postgres". -->
<add key="ApplicationStorage" value="SqlServer" />

​
Setting the Temp Data Path

The temp data path is the path where any temporary application data is saved. If it is not set or set to empty string, the App_Data path is used. The following folders would exist under the folder defined by this setting:
  • BLOBFiles
  • Logs
  • TempLib
  • ViewThumbnails
  • FileDelivery
  • DownloadStaging 
<!-- The path where any temporary application data is saved.
If not set or set to empty string, the App_Data path is used.". -->
<add key="TempDataPath" value="" />

​
Recycle the Application Pool

For changes to this file to take effect, you need to recycle the application pool in IIS or the website service on Linux.

Complete Example

The following is a complete example of a dbi.config file’s contents, including some example keys provided as comments for reference: 
<?xml version="1.0"?>
<configuration>
  <connectionStrings>
    <!-- SQL SERVER -->
    <add name="AppConnectionString" connectionString="Data Source=localhost; Initial Catalog=&quot;Dundas BI Instance1&quot;;User ID=DundasUser;Password=1234" />
 
    <!-- PostgreSQL -->
    <!--<add name="AppConnectionString" connectionString="Host=localhost;Port=5432;Database=&quot;Dundas BI Instance1&quot;;User ID=DundasBIUser;Password=1234;" />-->
  </connectionStrings>
  <appSettings>
    <!-- The type of database server hosting the Application database. Can be "SqlServer" or "Postgres". -->
    <add key="ApplicationStorage" value="SqlServer" />
     
    <!-- The path where any temporary application data is saved. If not set or set to empty string, the App_Data path is used.". -->
    <!--<add key="TempDataPath" value="" />-->
  </appSettings>
</configuration>
