The Dimension Cache has the following available options:
 

Enable Caching - Checking this will enable caching of dimensions on the local system. Note that for dimension(s) to be added to the global cache, you must enable caching for each dimension desired by checking the checkbox on the row of the dimension name.

Method - Specifies when the dimension will be added to the cache. Method has two possible options, one of which can be selected from the dropdown by clicking in the cell of the row/column

On Startup - Dimension will start running in the background as soon as the web application starts. Once it finishes running, it will be added to the cache.

On Demand - Dimension will start running in the background when it is requested the first time. Once it finishes running, it will be added to the cache.
