Container Usage 
The average container usage specifies the percentage of the pages of a container in the liveCache basis layer that are actually occupied. This value is current only directly after the database structure has been checked. Start to check the database structure for a liveCache database only if there are hardly any other activities running in the liveCache database. A database structure check for an individual container is not possible.
The average container usage can be displayed from the following user menus:
DBA Cockpit, Class Containers
liveCache Assistant, Class Containers
