How to change default OLAP Settings in JasperReports Server

JasperReports Server uses Mondrian properties that are set by Mondrian engine. For example, JasperReports Server v4.7 and v5.0 engine version is mondrian-3.2.0.13661. To override those properties /WEB-INF/classes/mondrian.properties file is used.

Some of the properties are updated by default. If you don't see any of the properties that are available in UI (Server Settings/OLAP settings) simply add them to the file and restart JasperReports Server, for example:

mondrian.rolap.queryTimeout=30
mondrian.util.memoryMonitor.enable=true
mondrian.util.memoryMonitor.percentage.threshold=180
