[Zope] Zope Database Cache

Hi, I have some questions about the Zope database cache. You can change the settings for this cache on the "Cache Parameters"-tab in the database management screen (/Control_Panel/Database). 1. The default target size is 400 objects. But the total number of objects in the combined caches is much larger. How does the target size influence the total number of objects in the cache? How should this setting be used? 2. "Total number of objects in all caches". I don't use any RamCacheManager. Does this mean that there is more than one database cache?
