About This Guide

Data Chooser is Slow

When building a list of available data sources for Ad Hoc Views, the Data Chooser runs sub-queries to filter out ad hoc reports and views that are stored at /adhoc/topics. When a large number of ad hoc reports and views are stored in the repository under that location, the sub-query can be slow. To improve performance, you can disable the sub-uery by settingskip.adhoc.datasource.check to true in jasperserver-pro/WEB-INF/js.config.properties.

If skip.adhoc.datasource.check is enabled, avoid using ad hoc reports as a data source.

Configuration File
.../WEB-INF/js.config.properties
Property	Description
skip.adhoc.datasource.check	To improve performance, disable the sub-queries by setting skip.adhoc.datasource.check to true.
