Problem Note 34796: Multiple queries might be generated when exporting large reports in SAS® Web Report Studio
 |  |  |  |
When exporting a report that contains a large number of rows, multiple queries might be submitted in order to satisfy the export request. In some cases, the extra queries might cause performance problems. (The extra queries can be seen in the workspace server log.)
If you experience performance problems, you can reduce the number of queries that are required to satisfy the export request by increasing the value of the wrs.report.tuning.offlinePages property in your LocalProperties.xml file.
Caution: The wrs.report.tuning.offlinePages property affects the entire application, not just exporting to Excel. This means that each time SAS Web Report Studio requests data from the server, using offline result sets, more data than usual will be downloaded and stored in the cache on the disk. So, you will need to monitor your available disk space.
If you already have a LocalProperties.xml file, then follow these steps. (If you do not have a LocalProperties.xml file, see SAS Note 32858.)
- Open your LocalProperties.xml file in a text editor.
- Add the following line (before the closing </properties> tag) and enter a value such as
1000. - Restart your servlet container (Tomcat, Websphere, or Weblogic).
<-- Offline Results page size (40 row pages). default 5 == 200 rows -->
<wrs.report.tuning.offlinePages>1000</wrs.report.tuning.offlinePages >
