How to Set CommandTimeout for the Report Server MSSQL Storage

Environment

Product Version	7.2.21.1125+
Product	Progress® Telerik® Report Server

Description

Starting with version R3 2021 SP2 (7.2.21.1125), the CommandTimeout of the Report Server MSSQL Storage is configurable. Generally, this should be set when you configure the MSSQL storage from the Configuration page of the Report Server along with the connection string. This is a bug in the Report Server UI that is reported in The MSSQL Storage Configuration page doesn't allow setting the CommandTimeout property.

Solution

You may configure the value of the CommandTimeout property for the MSSQL Storage in the ReportServerAdmin.config configuration file of your Report Server web application. The file resides by default in the installation folder of the Report Server web application, for example, C:\Program Files (x86)\Progress\Telerik Report Server\Telerik.ReportServer.Web. Here is a sample code for the config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="reportServer" type="Telerik.ReportServer.Web.Configuration.ReportServerConfigurationSection, Telerik.ReportServer.Web" requirePermission="false" allowLocation="true" />
  </configSections>
  <reportServer>
    <storage provider="MsSqlServer">
      <parameters>
                <parameter name="ConnectionString" value="Data Source=(local)\MSSQLSERVER01;Initial Catalog=RESTStorage;Integrated Security=SSPI" />
        <parameter name="commandTimeout" value="360" />
      </parameters>
    </storage>
  </reportServer>
</configuration>

You need to edit the file manually to add the command timeout configuration.
