Configuring the maximum cache size in memory
The cache can retain up to 0.5 GB of reporting data and if it reaches capacity, it frees up space for new reports by purging the data for the least frequently used reports.
Use the following:
portal.reports.cache.maxSizeInMemory
The unit of measure for the cache maxSizeInMemory value is bytes.
Example: portal.reports.cache.maxSizeInMemory=536870912
