Modifying performance settings for the RAS

The Server tab of the Report Application Server (RAS) in the Crystal Management Console allows you to modify the number of minutes before an idle connection is closed, and the maximum number of simultaneous processing threads.

The "Minutes Before an Idle Connection is Closed" setting alters the length of time that the RAS waits for further requests from an idle connection. Before you change this setting, it is important to understand that setting a value too low can cause a user's request to be closed prematurely, and setting a value that is too high can affect the server's scalability (for instance, if the ReportClientDocument object is not closed explicitly, the server will be waiting unnecessarily for an idle job to close).

The "Maximum Simultaneous Report Jobs" setting limits the number of concurrent reporting requests that a RAS processes. The default value is acceptable for most, if not all, reporting scenarios. The ideal setting for your reporting environment, however, is highly dependent upon your hardware configuration, your database software, and your reporting requirements. Thus, it is difficult to discuss the recommended or optimum settings in a general way. It is recommended that you contact your Crystal Decisions, Inc. sales representative and request information about the Crystal Enterprise Sizing Guide. A Crystal Services consultant can then assess your reporting environment and assist you in customizing these advanced configuration and performance settings.

Tip:    On Windows, you can also change these settings in the CCM. Stop the RAS and view its Properties. Click the Parameters tab. From the Option Type list, select Server.
