Scheduling

At this phase, you need to define the business view information and the updating policy of the in-memory cube with the following tabs:

General

Before you can schedule a cube task, you first need to configure the settings in this tab.

Move the cube to disk if insufficient memory is allocated

When the option is selected, the cube will be cached on disk when the specified memory size is not enough to hold it.

If the option is selected, when initiating or updating an in-memory cube, if the memory requirement is bigger than the cube's maximum memory allowed, or if all in-memory cubes' memory usage will be bigger than the maximum cube memory allowed, the cube will be swapped to disk, otherwise if this option is unselected, the cube status will be set to disabled.
