Microsoft SQL Server Reporting Services periodically restarts, and each restart clears the Reporting Services cache. After this cache has been cleared, it may take some time for the next report that is run to display. For example, you may have noticed that it takes a really long time for the first report that is run each morning to display.
To minimize the effect of Reporting Services restarts, a new class that is named SRSReportServerWarmup is included with cumulative update 7 for Microsoft Dynamics AX 2012 R2. When the SRSReportServerWarmup class runs, it prepares the report server for use by performing the following tasks:
- Loads Microsoft Dynamics AX business logic assemblies.
- Connects to Reporting Services.
- Runs a sample report that is named SRSReportServerWarmup.
As a best practice, you should schedule the batch job that runs the SRSReportServerWarmup class to run immediately after Reporting Services restarts. For more information about how to configure the batch job, see Run the SRSReportServerWarmup class.
