Modifying performance settings for Job Servers

By default, the Job Server runs jobs as independent processes rather than as threads. This method allows for more efficient processing of large, complex reports. The "Maximum Jobs Allowed" setting limits the number of concurrent independent processes (child processes) that the Job Server allows—that is, it limits the number of scheduled reports that the Job Server will process at any one time. You can tailor the maximum number of jobs to suit your reporting environment.

The default "Maximum Jobs Allowed" setting 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

You can also change the default directory where the Job Server stores its temporary files.
