Report Execution Caching II: Report Manager Perspective - Page 2

Settings to Configure Report Execution Caching from Report Manager

As we have learned, the primary objective of Report Execution caching is to enhance report performance by caching temporarily, upon the initial consumer-client request, reports for which we enable such caching. We make the settings to enable this capability, as well as specify its operational behavior, within the report execution properties. Report execution properties control how a report is processed. Execution properties must be set for each report individually, although they can be set to reference pre-established defaults, as we shall see.

As we saw in our hands-on practice session in Report Execution Caching I, setting Report execution properties within the SQL Server Management Studio is both straightforward and intuitive. In the subsections that follow, we will examine these settings for a sample report from the perspective of another avenue, the Report Manager. We will do so, once again, using a report from among the samples that are available to anyone installing Reporting Services 2005.

If you have not installed the samples, you’ll need to install them to use the sample report presented in the steps below. If you prefer to use a local report, the steps will be approximately the same for accessing the property settings.

Configure Report Execution Caching from the Report Manager

Most of us are aware that, among the graphical user, command-line and programmatic interfaces that Reporting Services makes available to us for performing management activities, Report Manager is perhaps the most user-friendly. This web-based management application interfaces with the Report Server via the Web Service API, and is easily accessed using a web browser. Report Manager has many uses, and affords us a straightforward means of flexibly managing access to all reports and related resources.

Let’s take a look at how we can adjust Report Execution caching settings for a report within the Report Manager. To do this, we will take the following steps:

1.  Open an instance of the web browser on the PC.

2.  Point the browser to the following URL:

http://<Server_Name>/Reports

NOTE: Replace <Server_Name> in the above with the name of the server hosting Report Manager in the local environment. Also, replace the default Reports directory with the appropriate virtual directory established in the local environment, if appropriate.

Report Manager’s home page next appears, somewhat similar to that shown in Illustration 2.

3.  Access the sample reports (mine are within the AdventureWorks Sample Reports directory shown in Illustration 2 above), by navigating into their containing folder(s) from the home page.

4.  Click-select the Sales Reason Comparisons report from among the sample reports listed, as depicted in Illustration 3.

The report briefly executes, and then opens.

5.  Click the Properties tab atop the report, as shown in Illustration 4.

6.  Click the Execution tab that appears on the left side of the page, as depicted in Illustration 5.

We arrive at the Execution properties page, where we can set execution properties for the currently selected report only. These options determine when report processing occurs, and, among other activities, we can set these options to govern a report run during off-peak hours, and the like, for flexible resource scheduling within our own environments. As we have learned, one of the options that might be useful to us might be to temporarily cache copies of a frequently accessed report. The idea, of course, would be to eliminate wait time for multiple users attempting to access the same report, say, within minutes of each other.
